Power Supply Modules
The power supply modules are hot pluggable. This means you can remove or
install one of the two functioning power supply modules without disrupting service.
The power supply modules are also interchangeable; that is, any power supply
module will fit in slot #0 or slot #10.
6.5.1
Removing a Power Supply Module
To remove a power supply module, do the following:
1. Disconnect the power cord from the power supply module.
2. Connect an ESD wrist strap to the ground jack on the CPU module shown in
Figure 6-7 or some other ground point on the chassis.
3. Using a flat-blade screw driver, loosen the captive screws at the top and
bottom of the module faceplate as shown in Figure 6-7. The bottom screw is
under the latch.
4. Grasp the latch and press the red release button, then rotate the latch
downward to disengage the module from the backplane connector. Carefully
slide the module out of the slot.
WARNING!!
The power supply module faceplate and internal surfaces can
become very hot. Handle with care.
Voltage is present in an open slot when the switch is operating. To
avoid personal injury or damage to surrounding components, do
not place hands or objects into an open slot.
CAUTION!
Always use an ESD wrist strap when removing and installing a
power supply module. The power supply module contains
sensitive electronic components. To avoid damage to the power
supply module, do not touch the module components.
Keep the power supply module in an ESD protective container or
anti-static bag when not in use.
CAUTION!
To avoid damaging the latch mechanism, press the red release
button all the way in before rotating the latch.
CAUTION!
To prevent overheating and possible damage to the switch, do not
operate the switch with an empty slot any longer than it takes to
install a new power supply module.
