Installing and removing power supplies
CAUTION:
Provide a circuit breaker for each power supply and make sure the circuit breaker is off before
installation.
This section applies only to the switch models that support removable power supplies.
The S5130S-28F-EI and S5130S-52F-EI switches each provide two power supply slots. They come
with power supply slot 1 empty and power supply slot 2 installed with a filler panel. You can install
one power supply, or two power supplies for redundancy. For information about power supplies
available for the S5130S-28F-EI and S5130S-52F-EI switches, see removable components in
S5130S-EI Switch Series Hardware Information and Specifications .
When two power supplies are installed, you can hot-swap a power supply. To avoid device damage
and bodily injury, follow the procedures in
Figure2-17 and Figure2-18 to install and replace a power
supply.
Figure2-17 Installation procedure
Figure2-18 Removal procedure
The installation and removal procedures are the same for power supplies. This guide uses the
PSR150-A1 power supply as an example.
Installing 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 as required.
3. Remove the filler panel (if any) from the target slot.
If you require only one power supply, install it in power supply slot 1 and make sure a filler panel
is installed in power supply slot 2.
4. Orient the power supply with the upside up. 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
Figure2-19 .
To prevent damage to the power supply and the connector on the switch backplane, insert the
power supply gently. If you encounter a hard resistance or the power supply tilts while inserting
the power supply, pull out the power supply, realign it with the slot, and then insert it again.
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
Figure2-19 .
If the captive screw cannot be tightly fastened, examine the installation of the power supply.
