For switches with replaceable fan modules, refer to the following information to replace the fan modules.
Do not operate a chassis for more than a few minutes with a missing cooling module. To ensure internal chassis air pressure is maintained and to avoid loss of traffic due to modules overheating and shutting down, leave a failed cooling module installed until you have a replacement.
Images in this topic might show switches that are not identical to the ones you are using. However, the procedure for replacing a fan module is the same for all Extreme Networks switches.I
Note
Read all of the information in this chapter thoroughly before attempting to replace a fan module.
