Replacing an XGM or XGM2 Series Port Option Card

This section describes how to replace XGM and XGM2 series port option cards in Summit X350, X450a, and X450e series switches.



Pluggable optical modules can become very hot after prolonged use. Take care when removing a pluggable optical module from the option card. If the pluggable optical module is too hot to touch, disengage the module and allow it to cool before removing it completely.


Summit port option cards are not hot-swappable. Disconnect power to the switch before installing or removing a Summit XGM or XGM2 series option card. After the Summit port option card is installed in a compatible switch, you can hot-swap pluggable optical modules. Use only optical modules approved by Extreme Networks.

To replace a port option card, follow these steps:

  1. Disconnect the AC power and any redundant power supply from the Summit switch.
  2. Attach an ESD-preventive wrist strap to your bare wrist and connect the metal end to an appropriate ground point on the equipment rack.
  3. Remove the screws that secure the option card to the switch.
    1. Save the screws for re-use.
  4. Pull the option card out of the switch and set it on an ESD-preventive surface.
  5. Align the sheet metal edges on the new option card with the card guides in the switch housing.
  6. Carefully slide the option card into the switch housing until the connectors engage and the card is flush with the back panel of the switch.

  7. Use the screws you removed from the old option card to secure the new option card to the back panel of the switch.


    If you remove a Summit option card and do not install a replacement, you must install a faceplate over the opening. An open slot could divert air from the switch and cause overheating.
