power supply and insert it again. Make sure the power supply has a good contact with the
connectors.
•
When the switch has two power supplies working in 1+1 redundancy, removing one power supply
does not affect system operation. If the switch has only one power supply, removing the power
supply causes power down of the switch.
•
If you are not to install a new power supply after removing the old one, install a filler panel in the
slot in time.
•
Use a torque of 5 kgf-cm (0.49 Nm) to fasten the captive screws on a power supply.
Installing a CA-70A12, PSR75-12A, or PSR150-D1 power
supply
The installation procedure is the same for the CA-70A12, PSR75-12A, and PSR150-D1 power
supplies. The following procedure installs a PSR75-12A power supply.
To install a PSR75-12A power supply:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Remove the filler panel from the target power supply slot as follows:
a.
Remove the screws from the filler panel.
b.
Use a flathead screwdriver to remove the filler panel.

3.
Unpack the power supply and verify that the power supply model is correct.
4.
Correctly orient the power supply with the power supply slot (use the letters on the power
supply faceplate for orientation), grasp the handle of the power supply with one hand and
support its bottom with the other, and slide the power supply slowly along the guide rails into
the slot (see callout 1 in
5.
Fasten the captive screws on the power supply with a Phillips screwdriver to secure the power
supply in the chassis (see callout 2 in
). If the captive screw cannot be tightly
fastened, verify the installation of the power supply.
As a best practice, use a torque of 5 kgf-cm (0.49 Nm) to fasten the captive screws.
6.
Install the filler panel over the empty power supply slot to prevent dust and ensure good
ventilation if you install only one power supply.
