before starting the procedures described in this guide. Do not
reconnect the power until the switch is completely reassembled
and cover plates are replaced on any open module slots or power
supply bays.
●If your switch is rack mounted, make sure that the rack is not going
to tip over as you complete these procedures. If the switch is
difficult to reach, remove it from the rack or other mounting
location before proceeding.

Installing the Replacement Fan Tray
Overview
The installation steps are:
1. Disconnect all AC power from the switch and remove any power supplies and
cover plates.
2. On the front of the switch, mark or otherwise note the location of the network
cables attached to the network modules in switch slots A and B so that you can
reconnect the cables to the correct ports at the end of this procedure. Then,
disconnect all network cables from modules that are installed in slots A and B
on the front of the switch.
Alternatively, if you have sufficient slack in the cables, you can leave the network
cables connected to the modules as you complete the next step.
3. Remove the Management module and any modules that you have installed in
slots A and B. (Remember which module is located in which slot).
4. Remove the old fan tray assembly.
5. Install the Replacement Fan Tray.
6. Reinstall the Management module into its slot and the network modules into
their previous positions in slots A and B. (Make sure you do not overtighten the
screws on the modules.)
7. If you disconnected the network cables in step 2, reconnect the cables to the
correct ports on the network modules.
8. On the back of the switch, reinstall the power supply or supplies and cover plates.
9. Reconnect the AC power to the power supplies.
10. Verify that the switch is operating correctly by observing the LEDs on the front
of the switch.
