Installing and Removing OCX1100 Switch Hardware Components


The OCX1100 switch chassis is a rigid sheet-metal structure that houses the hardware components. The field-replaceable units (FRUs) in OCX1100 switches are:

  • Power supplies

  • Fan modules

  • Transceivers

The power supplies (AC or DC), fan modules, and transceivers are hot-removable and hot-insertable: You can remove and replace them without powering off the switch or disrupting switch functions.


You must remove only one fan module at a time for replacement from the rear panel of the chassis. The switch continues to operate without thermal shutdown for a limited period of time (30 seconds) during the replacement of a fan module.
