7. Using the screws from the cover plate, secure the option card to the back panel of the switch.
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.
Note
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.
For information about installing or replacing the pluggable optical modules in the Summit option card,
refer to the Extreme Networks Pluggable Transceivers Installation Guide.
