When two power modules are installed, you can hot-swap a power module. To avoid device damage
and bodily injury, follow the procedures in
to install and replace a power
module.
Figure 19 Installation procedure
Figure 20 Removal procedure
The installation and removal procedures are the same for power modules. This guide uses the
PSR150-A1 power module as an example.
Installing a power module
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Unpack the power module and verify that the power module model is as required.
3.
Remove the filler panel (if any) from the target slot.
If you require only one power module, install it in power module slot 1 and make sure a filler
panel is installed in power module slot 2.
4.
Orient the power module with the upside up. Grasp the handle of the power module with one
hand and support its bottom with the other, and slide the power module slowly along the guide
rails into the slot. See callout 1 in
To prevent damage to the power module and the connector on the switch backplane, insert the
power module gently. If you encounter a hard resistance or the power module tilts while
inserting the power module, pull out the power module, realign it with the slot, and then insert it
again.
5.
Fasten the captive screws on the power module with a Phillips screwdriver to secure the power
module in the chassis. See callout 2 in
.
If the captive screw cannot be tightly fastened, examine the installation of the power module.

Removing a power module
