5 Using the screws from the cover plate, secure the option card to the back panel of the switch.
For information about installing or replacing the pluggable optical modules in the Summit option card,
refer to the Extreme Networks Pluggable Interface Modules Installation Manual.
NOTE
If you install only one pluggable optical module in the Summit option card, attach the appropriate cover plate or
dust cover over the remaining open optical module slot or cage.
Be sure that the switch option slot always has either an installed Summit option card or a faceplate over the
opening. An open slot could divert air from the switch and cause overheating.
