For the power modules available for the switch and their specifications, see "Appendix B FRUs and
compatibility matrixes."
Installing a PSR150-A1/PSR150-A2/PSR150-D1 power
module
CAUTION:
To prevent damage to the power module or the connectors on the backplane, insert the power
module gently. If you encounter a hard resistance when inserting the power module, pull out the
power module and insert it again.
The installation procedure is the same for PSR150-A1, PSR150-A2, and PSR150-D1 power
modules. The following procedure uses the PSR150-A1 power module as an example.
To install a PSR150-A1 power module:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Remove the filler panel, if any, from the target power module slot as follows:
a. Remove the screws on the filler panel.
b. Use a flathead screwdriver to remove the filler panel.
Figure 24 Removing the filler panel
3. Unpack the power module and verify that the power module model is correct.
4. Correctly orient the power module with the power module slot (use the letters on the power
module faceplate for orientation), 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 Figure 25).
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 Figure 25). If the ca
ptive screw cannot be tightly fastened,
verify the installation of the power module.
6. Install the filler panel over the empty power module slot to prevent dust and ensure good
ventilation if you install only one power module.
