Replacing the Disk Drive
Caution A 5-second delay is mandatory between removing a module, and either re-
installing it, or replacing it with another.
To replace one module with another, or to remove a module without replacing
it, use the following procedure:
1. Unscrew the retaining screws enough to disconnect them from the
threaded holes in the switch.
2. Using the extractor handles pull the module out from the slot.
3. Do one of the following:
• If installing another module of the same type, go to “Installation
Procedure” on page 1-3 and begin with step 2. A switch reset is not
required. The current configuration in that slot will apply to the new
module.
• If another module will not be installed in the slot (that is, the slot will
be left empty), re-install the cover plate over the slot opening.
Caution For proper cooling and reduction of electromagnetic emissions, ensure that
a slot cover is installed on any unused slot. In an operational chassis, an
unused slot should be covered if it is not used for more than 2 minutes.
Replacing the Disk Drive
The following is the procedure for replacing the Disk Drive in the module. The
module may be removed while the switch is powered on. The numbers in
Figure C-5 correspond to the step numbers below.
1. Using either a flat-bladed or Torx T-10 screwdriver loosen the retaining
screws securing the module.
2. Using the extractor handles, pull the module out from the slot and turn
it over. In the meantime, if the chassis is still operational, use a slot cover
to cover this slot, to ensure proper cooling.
3. Using a Cross Recess Type 1 No.1 (Philips tip) screwdriver remove the
four retaining screws holding the disk drive.
4. Slide the disk drive back to disconnect it.
5. Position the disk drive in the middle of the disk drive slot.
6. Using either side of the disk drive bracket, lift the disk drive out.
