Biamp Tesira SERVER Manuals

Specifying PoE switches for Biamp Tesira devices Many Biamp products are powered using PoE (Power over Ethernet) from a network switch. When powering many devices from one switch, it's important to ensure that the switch has enough power to supply all connected devices. This article is designed to aid AV network designers in PoE budget calculations for Tesira systems. Initial considerations In addition to ensuring network switches can handle the traffic that is intended to be transmitted through them, it is important to make sure the switches can power all the connected PoE devices. PoE (Power Over Ethernet) is a set of standards developed by the IEEE under the 802.3 publication that describes power provision over Ethernet. PoE Budget is a specification of network switches and multi-port PoE injectors. This power budget is a shared resource available as needed to all ports. Each PoE device negotiates power needs with the switch or PoE injector based on the class of the device. The device is then provided with power from the PoE budget accordingly. PoE budget may be exceeded during system operation if a network switch is not properly specified. This will cause the switch to turn off PoE on one and possibly all the ports. The communication with endpoint devices will be interrupted and Tesira performance could be temporarily or even permanently compromised. The terms PoE and PoE+ have some overlap in meaning. For this reason, PoE and PoE+ equipment will be generically referred to as “PoE equipment” throughout this article. Calculating PoE device counts Calculating how many devices a single network switch can power will help identify how many switches are required to power all the PoE devices in the system. Please follow these steps: 1. Check the total PoE budget of the switch in the manufacturer's specification. 2. Check the Biamp endpoint device's PoE class using the provided technical documentation or this Tesira PoE devices reference chart. 3. Make note of the "Max Power From Switch" value for the PoE class of your selected endpoint devices. * Copyright 2013-2020 Biamp Systems http://support.biamp.com/ 1

Adding or removing I/O cards in a Tesira server It is possible to modify the I/O card configuration of a Tesira SERVER or SERVER-IO in the field, and Biamp offers individual card kits for this purpose. This article explains how to add or remove I/O cards in a Tesira server, and get it up and running again. Preparations Before unplugging the Tesira server, the following steps should be followed: 1. Save a backup copy of the configuration file that is loaded to the Tesira system, if applicable. You can do this by connecting to the Tesira system using Tesira software, and then disconnecting from the system and choosing File→Save As. 2. Perform a "Reset Device" on the Tesira server to clear out its configuration file. You can do this in the Device Maintenance window in Tesira software (System→Network→Perform Device Maintenance). 3. Update the firmware of the Tesira server to the latest version available. This helps to avoid firmware version mismatches when adding newer I/O cards to an older device. Firmware upgrade instructions can be found at this link: Tesira firmware update instructions. Opening the Tesira server The next step is to open the Tesira server and add/remove/modify the I/O cards as desired. Remove screws and top cover 1. Unplug all cables (including the power cable) and connectors from the Tesira server and place it on a properly grounded anti-static mat. Ensure that you are properly grounded using an ESD wrist strap. Failure to take proper ESD precautions may cause damage to the I/O cards and/or other internal components of the server. 2. Using a #1 Philips screwdriver, remove the three screws along the top of the rear panel. For the updated chassis you will need to remove 3 screws along the top front and 3 screws on the top rear of the chassis 3. Pull up on the tabs protruding from the rear of the top cover to dislodge it. Then, pull the top cover towards the rear to remove it completely. For the updated chassis simply pull on the two rear tabs ro remove it once the screws have been taken out. Replacing a card 1. Remove the three screws that attach the I/O card to the rear chassis (the top-right, middle-left, and bottom-right screws). For the updated chassis there will only be one screw attaching the I/O card to the rear of the chassis (top- Copyright 2013-2020 Biamp Systems http://support.biamp.com/ 1
