The NetGuardian has two screw terminal barrier plug power connectors, located on the left side of the back panel. (See Figure 6.3.1.) Before you connect a power supply to the NetGuardian, test the voltage of your power supply: · Connect the black common lead of a voltmeter to the ground terminal of the battery, and connect the red lead of the voltmeter to the battery's –48 VDC terminal. The voltmeter should read between –43 and –53 VDC. If the reading is outside this range, test the power supply. To connect the NetGuardian to a power supply, follow these steps: 1. Remove Fuse A and Fuse B from the back panel of the NetGuardian. Do not reinsert the fuse until all connections to the unit have been made. 2. Remove the power connector plug from Power Connector A. Note that the plug can be inserted into the power connector only one way — this ensures that the barrier plug can only be reinserted with the correct polarity. Note that the –48V terminal is on the left and the GND terminal is on the right. 3. Use the grounding lug to properly ground the unit. 4. Insert a battery ground into the power connector plug's right terminal and tighten the screw; then insert a –48 VDC line to the plug's left terminal and tighten its screw. 5. Push the power connector plug firmly back into the power connector. If the power feed is connected correctly, the LED by the connector will light GREEN. The LED by the power connector will be off if the power feed is reversed. 6. Repeat Steps 2–5 for Power Connector B. 7. Reinsert Fuse A and Fuse B to power the NetGuardian. The front panel LEDs will flash RED and GREEN.

The NetGuardian 216F has a 10-BaseT Ethernet switch for connecting through LAN. To connect the NetGuardian 216F to the LAN, insert a standard RJ45 Ethernet cable into one of the Ethernet ports. From the NetGuardian 216F, the connection can be routed via Ethernet to a local subnet of up to 7 devices. Yost RS-232 RJ45 Connector Ethernet port pinout The pinout diagram for the Ethernet switch port is shown above.

6.5 Alarm and control relay connectors The NetGuardian's discrete alarm inputs, control relay outputs, and analog alarm inputs are connected through the 50-pin connectors labeled "Discretes 1–16, Analogs 1-4, and Relays 1-2" on the back panel. 6.5.1 Alarm and Control Relay Connector Pinout Table Discretes 1–16 RTN ALM RTN ALM ALM 1 1 26 ALM 9 9 34 ALM 2 2 27 ALM 10 10 35 ALM 3 3 28 ALM 11 11 36 ALM 4 4 29 ALM 12 12 37 ALM 5 5 30 ALM 13 13 38 ALM 6 6 31 ALM 14 14 39 ALM 7 7 32 ALM 15 15 40 ALM 8 8 33 ALM 16 16 41 Alarm, amphenol connector, and control relay pinout (continued on next page) Analogs 1–4 + – ANA 1 21 46 ANA 2 22 47 ANA 3 23 48 ANA 4 24 49 GND 25 50 Control Relatys 1–2 NO/NC CO CTRL 1 17/42 43 CTRL 2 19/44 18 FUSE 20/NA 45 Alarm, amphenol connector, and control relay pinout The table shows the pinouts for the 50-pin connectors "Discretes 1-16," and "Analogs 1-4" and "Control Relays 1-2."

Both of the 50-pin connectors on the back panel of the NetGuardian can be connected to the optional 25-pair 66 Block Connector (part number D-PR-966-10A-00). For 66 block pinout and color code information, see diagram below for Discretes 1–16. Note: If connecting to a 50-pair split block, all connections should be made on the two pin columns closest to the right-hand side of the block or bridge clips should be installed. Optional 66 block pinout for Discretes 1–16

The integrated temperature and battery sensor monitors the ambient temperature and the NetGuardian's power feeds. This option is available only if it was ordered with your NetGuardian. The integrated temperature sensor measures a range of -22° F to 158° F (-30° C to 70° C) within an accuracy of ± 1°.

The analogs are controlled by the dipswitches to the left of the Amphenol connector (located at the back of the unit). For milliamp sensor operation, turn the dipswitch on by placing it in the on position. For normal operation, place the dipswitch in the off position. Note that the dipswitch is internal, and requires the case to be opened in order to change the setting. ! Hot Tip! WARNING WARNING: Do not put the dipswitches in the on position unless you are sure of the analog setting. Having the dipswitches on will put a 250 ohm resistor across the input lines. Any voltage beyond 5V or 20 mA will damage components.

You can provision the NetGuardian using either the Edit216F software or the Web interface. The NetGuardian also supports a limited TTY interface for configuring some basic options. (For full instructions on configuring the NetGuardian, see the software configuration guides on the NetGuardian Resource CD.) You can provision the NetGuardian either locally through the craft port or remotely through a LAN connection. However, to access the NetGuardian via LAN you must first make a temporary connection to the NetGuardian and assign it an IP address on your network. For more information, see Section 10, "Connecting to the NetGuardian."

10 ... via Craft Port 10.1 NetGuardian Craft Port The simplest way to connect to the NetGuardian is over a physical cable connection between your PC's COM port and the NetGuardian's craft port. Note: You must be connected via craft port to use the TTY interface, but you don't have to be connected to a NetGuardian unit to use Edit216F. You only need a connection to the unit to read or write configuration files to its NVRAM. You can use Edit216F on an unconnected PC to create and store NetGuardian configuration files. Use the DB9M-DB9F download cable provided with your NetGuardian to make a craft port connection. You can perform all configuration tasks via the craft port with Edit216F — but if you like, you can connect via the craft port just to configure the NetGuardian's Private LAN IP address, and then do the rest of your configuration via a LAN connection. ... via LAN 10.2 NetGuardian LAN Link Once LAN settings are provisioned, you can connect to the NetGuardian over a LAN connection by connecting to one of the seven 10/100/1000BaseT Ethernet switch ports. This is a very convenient way to provision multiple NetGuardian units at multiple locations. Note: You don't have to be connected to a NetGuardian unit to use Edit216F. You only need a connection to the unit to read or write configuration files to its NVRAM. You can use Edit216F on an unconnected PC to create and store NetGuardian configuration files. To connect to the NetGuardian via LAN, all you need is the unit's IP address (Default IP address is 192.168.1.100). If you have physical access to the NetGuardian, the easiest thing to do is connect to the unit through the craft

connection, if you want. For instructions, see section: "Connecting to the NetGuardian via Craft Port." If you DON'T have physical access to the NetGuardian, you can make a LAN connection to the unit by temporarily changing your PC's IP address and subnet mask to match the NetGuardian's factory default IP settings. Follow these steps: 1. Look up your PC's current IP address and subnet mask, and write this information down. 2. Reset your PC's IP address to 192.168.1.200. 3. Reset your PC's subnet mask to 255.255.0.0. You may have to reboot your PC to apply your changes. 4. Once the IP address and subnet mask of your computer coincide with the NetGuardian's, you can access the NetGuardian via a Telnet session or via Web browser by using the NetGuardian's default IP address of 192.168.1.100. 5. Provision the NetGuardian with the appropriate information, then change your computer's IP address and subnet mask back to their original settings. Note: You can ping the NetGuardian to confirm connectivity through the Ethernet switch ports.

The TTY interface is the NetGuardian's built-in provision controls for basic configuration of the NetGuardian. Configure the NetGuardian's Ethernet port settings, monitor the status of base and system alarms, operate control relays, view live ping targets , view debug or create proxy connections to other ports. For more advanced configuration tools, please use the Web browser interface or the Edit216F utility. To use the TTY interface with the NetGuardian, all you need is any PC with terminal emulation software and a connection to the NetGuardian. This connection can be a direct connection to the NetGuardian's front panel craft port or a remote connection via Telnet. Some initial software configuration must be performed before you can use a remote connection to the NetGuardian. The TTY interface is primarily used for configuring and provisioning the NetGuardian, but you can also use it to ping IP targets, view system statistics, and data port activity. NOTE: The TTY default username and password is "dpstelecom". Menu Shortcut Keys 11.1 The letters before or enclosed in parentheses ( ) are menu shortcut keys. Press the shortcut key to access that option. Pressing the ESC key will always bring you back to the previous level. Entries are not case sensitive.

The NetGuardian must be assigned an IP address before you will be able to connect via LAN using a Telnet client or a Web browser. To connect via LAN, the minimum configuration requires setup of the IP address and subnet mask. Follow the instructions below to configure the NetGuardian's IP address, subnet mask, and default gateway for Ethernet connectivity. Configure the Ethernet port parameters 1. Once a connection is established, the NetGuardian will respond with "Password." 2. Type the default password, "dpstelecom," then press Enter. Note: DPS strongly recommends changing the default password. 3. The NetGuardian's main menu will appear. 4. Type C for the C)onfig menu. 5. Type E for E)dit menu. 6. Type E for port settings. 7. Configure the unit address, subnet mask, and default gateway. 8. ESC to the main menu. 9. When asked if you would like to save changes, type Y (yes). 10. Reboot to save the new configuration to the NetGuardian. 11. Now you can connect to the NetGuardian via LAN and complete the configuration.

Connect a PC running terminal emulation software to the craft port or connect via LAN using a Telnet client with emulation to port 2002 to reach the monitor menu selection.

See Section 12.4, "ASCII Conversion," for specific ASCII symbol conversion. Data port activity can be viewed from the M)onitor menu > p(O)rts option

The NG216F can support 2 SPF connections. When using a compatible OpticalZonu SFP transceiver, the contents of their registers can be read and the fiber connection status and parameters are displayed in the TTY interface. The TTY interface displays information about the transceiver such as its Type, Vendor, Part No., and Wavelength, as well as diagnostic information on the connection status such as TX Power, RX Power, Voltage, Bias, and Temperature. You can monitor SFP port 1 and port 2 individually by entering in the following commands, depending on which port you wish to monitor: Port 1: Port 2:

If the SFP transceivers are Micro OTDR capable, the distance to the fiber fault will be displayed in this TTY interface when a fault is detected. It will take 15 - 30 seconds after power up for the micro OTDR to run. Once micro OTDR runs, the vendor name field will change from OpticalZonu,Corp to OZC followed by OTDR data: 1. The first number after OZC indicates the number of reflections (02 in the example below). 2. The second number x2 indicates distance to the farthest fault (00128 in the example below means fault is 256m away [128 x 2]).

Useful in testing integrity of SNMP trap alarm reporting. To turn the feature off, set the Timed Tick timer to 0. 19 Netw ork Time Server Communication w ith Netw ork Time Server has failed. Try pinging the Netw ork Time Server’s IP Address as it is configured. If the ping test is successful, then check the port setting and verify the port is not being blocked on your netw ork. 21 Duplicate IP Address The unit has detected another node w ith the same IP Address. Unplug the LAN cable and contact your netw ork administrator. Your netw ork and the unit w ill most likely behave incorrectly. After assigning a correct IP Address, reboot the unit to clear the System alarm. 33 Pow er Up The unit has just come-online. The set alarm condition is follow ed immediately by a clear alarm condition. Seeing this alarm is normal if the unit is pow ering up. 36 Lost Provisioning The internal NVRAM may be damaged. The unit is using default configuration settings. Use Web or latest version of NGEditG5 to configure unit. Pow er cycle to see if alarm goes aw ay. May require RMA. 37 DCP Poller Inactive The unit has not seen a poll from the Master for the time specified by the DCP Timer setting. If DCP responder is not being used, then set the DCP Unit ID to 0. Otherw ise, try increasing the DCP timer setting under timers, or check how long it takes to cycle through the current polling chain on the Master system. 38 Ethernet not active The Net1 LAN port is dow n. Check LAN cable. Ping to and from the unit.

12.2 The SNMP Manager allows the user to view alarm status, set date/time, issue controls, and perform a resync. The display and tables below outline the MIB object identifiers. Table B.1 begins with dpsRTU; however, the MIB object identifier tree has several levels above it. The full English name is as follows: root.iso.org.dod.internet.private.enterprises.dps-Inc.dpsAlarmControl.dpsRTU. Therefore, dpsRTU's full object identifier is 1.3.6.1.4.1.2682.1.2. Each level beyond dpsRTU adds another object identifying number. For example, the object identifier of the Display portion of the Control Grid is 1.3.6.1.4.1.2682.1.2.3.3 because the object identifier of dpsRTU is 1.3.6.1.4.1.2682.1.2 + the Control Grid (.3) + the Display (.3).

13 Here are answers to some common questions from NetGuardian users. The latest FAQs can be found on the NetGuardian support web page, http://www.dpstele.com . If you have a question about the NetGuardian, please call us at (559) 454-1600 or e-mail us at [email protected] General FAQs 13.1 Q. How do I telnet to the NetGuardian? A. You must use Port 2002 to connect to the NetGuardian. Configure your Telnet client to connect using TCP/IP (not "Telnet," or any other port options). For connection information, enter the IP address of the NetGuardian and Port 2002. For example, to connect to the NetGuardian using the standard Windows Telnet client, click Start, click Run, and type "telnet 2002." Q. How do I connect my NetGuardian to the LAN? A. To connect your NetGuardian to your LAN, you need to configure the unit IP address, the subnet mask and the default gateway. A sample configuration could look like this: Unit Address: 192.168.1.100 subnet mask: 255.255.255.0 Default Gateway: 192.168.1.1 Save your changes by writing to NVRAM and reboot. Any change to the NetGuardian's IP configuration requires a reboot. Q. When I connect to the NetGuardian through the craft port on the front panel it either doesn't work right or it doesn't work at all. What's going on? A. Make sure your using the right COM port settings. Your COM port settings should read: Bits per second: 9600 (9600 baud) Data bits: 8 Parity: None Stop bits: 1 Flow control: None Important! Flow control must be set to none. Flow control normally defaults to hardware in most terminal programs, and this will not work correctly with the NetGuardian. Q. I can't change the craft port baud rate. A. If you select a higher baud rate, you must set your terminal emulator program to the new baud rate and press Enter. If your terminal emulator is set to a slower baud rate than the craft port, normal keys can appear as a break key — and the craft port interprets a break key as an override that resets the baud rate to the standard 9600 baud. Q. How do I use the NetGuardian to access TTY interfaces on remote site equipment? A. If your remote site device supports RS-232, you can connect it to one of the eight data ports located on the NetGuardian back panel. To make the data port accessible via LAN, configure the port for TCP/IP operation. You now have a LAN-based proxy port connection that lets you access your device's TTY interface through a Telnet session. Q. How do I telnet to the NetGuardian? A. Configure your Telnet client with these options: · Connect using TCP/IP (not "Telnet," or any other port options) · Enter the IP address of the NetGuardian · Enter Port 2002 Example: To connect using the Windows Telnet client, click Start, click Run, and type telnet 126.12.220.8 2002.

connectors. Q. I just changed the port settings for one of my data ports, but the changes did not seem to take effect even after I wrote the NVRAM. A. In order for data port and craft port changes (including changes to the baud rate and word format) to take effect, the NetGuardian must be rebooted. Whenever you make changes, remember to write them to the NetGuardian's NVRAM so they will be saved when the unit is rebooted. Q. The LAN link LED is green on my NetGuardian, but I can't poll it from my T/Mon. A. Some routers will not forward packets to an IP address until the MAC address of the destination device has been registered on the router's Address Resolution Protocol (ARP) table. Enter the IP address of your gateway and your T/Mon system to the ARP table. Q. What do the terms "port," "address," "display" and "alarm point" mean? A. These terms refer to numbers that designate the location of a network alarm, from the most general (a port to which several devices are connected) to the most specific (an individual alarm sensor). Port: A number designating a serial port through which a monitoring device collects data. Address: A number designating a device connected to a port. Display: A number designating a logical group of 64 alarm points. Alarm Point: A number designating a contact closure that is activated when an alarm condition occurs. For example, an alarm point might represent a low oil sensor in a generator or an open/close sensor in a door. These terms originally referred only to physical things: actual ports, devices, and contact closures. For the sake of consistency, port-address-display-alarm point terminology has been extended to include purely logical elements: for example, the NetGuardian reports internal alarms on Port 99, Address 1. Q. What characteristics of an alarm point can be configured through software? For instance, can point 4 be used to sense an active-low signal, or point 5 to sense a level or a edge? A. The NetGuardian's standard configuration is for all alarm points to be level-sensed. You cannot use configuration software to convert alarm points to TTL (edge-sensed) operation. TTL alarm points are a hardware option that must be specified when you order your NetGuardian. Ordering TTL points for your NetGuardian does not add to the cost of the unit What you can do with the configuration software is change any alarm point from "Normal" to "Reversed" operation. Switching to Reversed operation has different effects, depending on the kind of input connected to the alarm point: · If the alarm input generates an active-high signal, switching to Reversed operation means the NetGuardian will declare an alarm in the absence of the active-high signal, creating the practical equivalent of an active-low alarm. · If the alarm input generates an active-low signal, switching to Reversed operation means the NetGuardian will declare an alarm in the absence of the active-low signal, creating the practical equivalent of an active-high alarm. · If the alarm input is normally open, switching to Reversed operation converts it to a normally closed alarm point. · If the alarm input is normally closed, switching to Reversed operation converts it to a normally open alarm point. Q. Every time my NetGuardian starts up, I have to reenter the date and time. How can I get the NetGuardian to automatically maintain the date and time setting? A. You have three options for keeping the correct time on your NetGuardian: Real Time Clock Option: You can order your NetGuardian with the Real Time Clock hardware option. Once it's set, the Real Time Clock will keep the correct date and time, regardless of reboots. Network Time Protocol Synchronization: If your NetGuardian has Firmware Version 2.9F or later, you can configure the unit to automatically synchronize to a Network Time Protocol (NTP) server. · To get the latest NetGuardian firmware, sign in to MyDPS at www.dpstelecom.com/mydps. · For instructions on configuring your NetGuardian to use NTP synchronization, see your Edit216F or NetGuardian Web Browser Interface user manual. T/Mon RTU Time Sync Signal: You can configure your T/Mon NOC to send an RTU Time Sync signal at a

automatically synchronize the NetGuardian's clock to the T/Mon's clock. And if you set your T/Mon to NTP synchronization, you'll make sure you have consistent, accurate time stamps throughout your monitoring network. Q. How do I back up my NetGuardian configuration? A. There are two ways to back up NetGuardian configuration files: Use Edit216F NGEdit4 can read the configuration of a NetGuardian unit connected to your PC via LAN, modem or COM port. You can then use NGEdit4 to save a NetGuardian configuration file on your PC's hard disk or on a floppy disk. With Edit216F you can also make changes to the configuration file and write the changed configuration to the NetGuardian's NVRAM. Use FTP You can use File Transfer Protocol (FTP) to read and write configuration files to the NetGuardian's NVRAM, but you can't use FTP to edit configuration files. SNMP FAQs 13.2 Q. Which version of SNMP is supported by the SNMP agent on the NetGuardian? A. SNMP v1 and v2.0c. Q. How do I configure the NetGuardian to send traps to an SNMP manager? Is there a separate MIB for the NetGuardian? How many SNMP managers can the agent send traps to? And how do I set the IP address of the SNMP manager and the community string to be used when sending traps? A. The NetGuardian begins sending traps as soon as the SNMP managers are defined. The NetGuardian MIB is included on the NetGuardian Resource CD. The MIB should be compiled on your SNMP manager. (Note: MIB versions may change in the future.) The unit supports a main SNMP manager, which is configured by entering its IP address in the Trap Address field of Ethernet Port Setup. You can also configure up to eight secondary SNMP managers, which is configured by selecting the secondary SNMP managers as pager recipients. Community strings are configured globally for all SNMP managers. To configure the community strings, choose System from the Edit menu, and enter appropriate values in the Get, Set, and Trap fields. Q. Does the NetGuardian support MIB-2 and/or any other standard MIBs? A. The NetGuardian supports the bulk of MIB-2. Q. Does the NetGuardian SNMP agent support both NetGuardian and T/MonXM variables? A. The NetGuardian SNMP agent manages an embedded MIB that supports only the NetGuardian's RTU variables. The T/MonXM variables are included in the distributed MIB only to provide SNMP managers with a single MIB for all DPS Telecom products. Q. How many traps are triggered when a single point is set or cleared? The MIB defines traps like "major alarm set/cleared," "RTU point set," and a lot of granular traps, which could imply that more than one trap is sent when a change of state occurs on one point. A. Generally, a single change of state generates a single trap, but there are two exception to this rule. Exception 1: the first alarm in an "all clear" condition generates an additional "summary point set" trap. Exception 2: the final clear alarm that triggers an "all clear" condition generates an additional "summary point clear" trap. Q. What does "point map" mean? A. A point map is a single MIB leaf that presents the current status of a 64-alarm-point display in an ASCII-readable form, where a "." represents a clear and an "x" represents an alarm. Q. The NetGuardian manual talks about two control relay outputs. How do I control these from my SNMP manager? A. The control relays are operated by issuing the appropriate set commands, which are contained in the DPS Telecom MIB. For more information about the set commands, see Appendix, "Display Mapping," in any of the NetGuardian software configuration guides.

A. The NetGuardian alarm point descriptions are individually defined using the Web Browser, TTY, or Edit216F configuration interfaces. Q. My SNMP traps aren't getting through. What should I try? A. Try these three steps: 1. Make sure that the Trap Address (IP address of the SNMP manager) is defined. (If you changed the Trap Address, make sure you saved the change to NVRAM and rebooted.) 2. Make sure all alarm points are configured to send SNMP traps. 3. Make sure the NetGuardian and the SNMP manager are both on the network. Use the NetGuardian's ping command to ping the SNMP manager.

warranty period free of charge. DPS Telecom products not under warranty can still be repaired with a service charge. In the event that a DPS Telecom product needs repaired, contact Technical Support and a technician can help solidify the field diagnosis, and issue and RMA number if needed. An RMA will be issued if the product has a failed feature or component, if the technicians are unable to resolve the issue remotely, or if the wrong product is ordered or shipped. DPA Telecom, on average, returns RMA units within 4 weeks and will email the RMA submitter on the return shipment with a tracking number. Under urgent circumstances, DPS Telecom will issue an advanced replacement. DPS Telecom will send a replacement unit in advance if the problem affects service or if technicians can better troubleshoot an issue. In both cases the advance replacement depends on DPS Telecom stock on hand.
