Procedure

  1. Disconnect the Ethernet and power cable from the front of the terminal server.

    Figure 1. Front of Terminal Server

  2. Push the terminal server back through brackets before disconnecting the wires in the back.
    note:

    You may have to loosen the bracket mounting nut to easily slide out the terminal server.

    Figure 2. Terminal Server - Outside of Holding Bracket

  3. When the terminal server is outside of the brackets, disconnect the rear wires. Confirm that all the cables are properly labeled to aid re-connection.
  4. Before putting the new terminal server into the cabinet, record the MAC address on the bottom of the terminal server. This address will be used in Step 8.d.

    Figure 3. MAC Address on Terminal Server

  5. Install the replacement terminal server. After the rear wires are plugged into the new server, push the terminal server through the rear of the brackets towards the front.
  6. Install the PEM or AUX.
  7. Connect the front Ethernet and power cables Figure 1. Once the power cable is connected, a steady green LED should be on the power supply. The power supply for the terminal server is located on the CAM Chassis shelf. You may have to pull out the CAM Chassis in order to properly view the power supply LED.

      Figure 6. Terminal Server - Reset Button

    2. Continue to hold the reset button, then remove the DC power cable while still holding in the reset button. Reinstall the power cable. The LED blinks on and off in a 1:5:1 sequence. If you interrupt the continuous hold momentarily, by slip or mistake, the 1:5:1 sequence will not appear. If this is the case, repeat until the LED blink sequence is as noted. Once the LED is on continuously, it has received its IP from the host.
  10. Open the mgd_term windows to verify connections to AGP and SCP.
    1. Click C Shell in the Service Desktop Manager.
    2. Type mgd_term and press Enter.
