You can use the Open Services Networking Module (OSN|M) as an expansion module installed in an expansion module slot on the rear panel of a Switch 5500G. It provides a software and hardware platform that can run various services. After an OSN|M is inserted into the expansion module slot, it interacts with the switch through its two internal service interfaces, which conforms to the software and hardware interface specifications defined by OSN. An OSN|M runs an independent Linux system. To configure and maintain this system, you can log in using several methods. You can develop and load service software on the OSN system to implement ...

Appearance Figure 1 displays the front view of the OSN|M. Figure 1 OSN|M appearance Front Panel This section describes the OSN|M’s front panel. Front Panel View An OSN|M provides one USB 2.0 interface, one console port, and one 10/100 Base-TX management Ethernet port. Figure 2 illustrates the front panel of an OSN|M.

LEDs There are PWR, SYS, HDD, and management Ethernet port LEDs on the front panel of an OSN|M. Table 1 describes the four LEDs. Interface Specifications Console port The console port on the OSN|M’s front panel conforms to the EIA/TIA-232 asynchronous serial port specifications. You can use the console port to log into and then configure the OSN|M’s Linux system. Refer to Table 2 for the console port specifications. Table 1 The OSN|M front panel’s LED descriptions LED Color Status Function PWR Green Green, solid ON Normal Green, blinking The module is being loaded. OFF The module is powered off. SYS Green/R ...

You can use the 10/100Base-TX management Ethernet port on the OSN|M’s front panel for management only; not for exchanging data. Use this port to log into the OSN|M’s Linux system through SSH, and then to configure the Linux system. Refer to Table 3 for the management Ethernet port specifications. Interface standard EIA/TIA-232 Cable type Asynchronous serial port cables Baud rate (bps) ■ 300 ■ 1200 ■ 2400 ■ 4800 ■ 9600 (default) ■ 19200 ■ 38400 ■ 56000 ■ 115200 Table 3 Management Ethernet port specifications Specification Description Connector type RJ45 Number of connectors 1 Interface stan ...

USB interface Use the USB interface on the OSN|M’s front panel to connect a storage medium such as a USB flash disk to perform file related operations. Refer to Table 4 for the USB interface specifications. Hardware Configuration Table 5 describes the hardware components of the OSN|M. c CAUTION: Do not replace OSN|M hardware components yourself. Doing so can damage the module. Table 6 describes the hard disk’s default partitioning. Table 4 USB interface specifications Specification Description Connector type USB interface Number of connectors 1 Interface standard USB 2.0 (backward compatible) Transmit rate � ...

leave-factory setting is null. /dev/hda3 swap swap The Linux system’s swapping partition. When you boot from hard disk using Elilo, it uses this partition as the system’s swapping partition. /dev/hda5 /opt ext The partition provided for the users. It is the system’s largest partition. System, files are not saved on this partition. /dev/hda6 vboot vfat The Linux system’s boot partition. The boot loader Elilo can identify the vfat partition only. The Linux kernel and ramdisk file are stored on this partition. Table 6 Default partitioning of the OSN|M ha ...

15 3 OSN|M Installation Installing and Removing the OSN|M The Switch 5500G supports hot swapping the OSN|M. c CAUTION: If the Linux system is running on an OSN|M, use the poweroff command to exit the system before removing the OSN|M. Installing an OSN|M in a Switch 5500G To install the OSN|M, perform the following steps: 1 Put on an ESD-preventive wrist strap and make sure that the ESD-preventive wrist strap is properly grounded. Then take the OSN|M out of the package. 2 Unscrew the mounting screws on the switch’s expansion module filler panel and remove the filler panel. 3 Hold the two sides of the OSN|M front panel ...

Figure 3 Install an OSN|M in a switch Removing the OSN|M 1 Put on an ESD-preventive wrist strap and ensure that the ESD-preventive wrist strap is properly grounded. 2 Loosen the fastening screws on both sides of the OSN|M using a screwdriver. 3 Hold the two sides of the OSN|M front panel with both hands and draw back the module until the module is fully separated from the switch. c CAUTION: ■ Hold the two sides rather than the middle of the OSN|M front panel to install or remove the OSN|M. Otherwise, the OSN|M may be out of shape. ■ Do not apply excessive force to install or remove an OSN|M, and do not touch the s ...

17 Connecting the Management Ethernet Port Cable To connect the management Ethernet port cable, perform the following steps: c CAUTION: When connecting the cable, pay attention to the mark on the interface to insert it in the correct direction, otherwise, you may damage the interface or the OSN|M. 1 Connect the management Ethernet port to a terminal. ■ If the terminal to be connected is a PC or router, use a crossover cable to connect the management Ethernet port to an Ethernet port of the PC or router. ■ If the terminal to be connected is a HUB or switch, use a standard cable to connect the management ...

Linux System Login Options You can log into the OSN|M Linux system through: ■ The OSN|M’s console port. ■ The OSN|M’s management Ethernet port using SSH. ■ The OSN|M’s internal service interface using SSH ■ A serial port redirection after you log into the switch. You can connect to the switch’s OSN|M or to another switch’s (within the same fabric) OSN|M to which you have logged in through a CLI. After you connect to the OSN|M’s Linux system, you need to input the correct username and password. The default username and password are both root. Logging In Through the Console Port In this exampl ...

Logging In Through the OSN|M Management Ethernet Port Using SSH The SSH server function is enabled on the OSN|M by default. You can use SSH on the SSH client to log into the Linux system through the OSN|M’s management Ethernet port performing the following steps: 1 Connect one end of the cable to the switch’s Ethernet port and the other end to the OSN|M’s management Ethernet port. 2 Power on the OSN|M and log into the OSN|M’s Linux system by executing the ssh2 command on the switch. The management Ethernet port’s default IP address is 192.168.0.2/24. Configuration Example # Create a VLAN inter ...
