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.
Caution
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.
Caution
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.
a. 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.
