Installing/removing a power supply
In power redundancy mode, you can replace a power supply without powering off the switch but you must
strictly follow the installation and procedures in Figure 21 and Figure 22 to avoid any bodily injury or
damage to the switch.
Provide a circuit breaker for each power supply.

Installing a PSR150 power supply
To prevent damage to the power supply or the connectors on the backplane, insert the power supply
gently. If you encounter a hard resistance while inserting the power supply, pull out the power supply and
insert it again.
For the PSR150-A1 and PSR150-D1 power supplies, the installation and removal procedures are the
same. The following takes the PSR150-A1 power supply as an example.
To install a power supply:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Unpack the power supply and verify that the power supply model is correct.
3. 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 Figure 23).
4. Fasten the captive screws on the power supply with a Phillips screwdriver to secure the power
supply in the chassis (see callout 2 in Figure 23). If the captive screw cannot be tightly fastened,
verify the installation of the power supply.
5. Install the filler panel over the empty power supply slot to prevent dust and ensure good ventilation
if you install only one power supply.
