Replacing a Power Supply Module
The switch requires two power supplies for redundancy. With one power supply providing the necessary
power for operations, you can replace the other power supply during operations so long as the new power
supply has the same airflow direction as the other modules in the chassis.
You can replace a power supply with another supported power supply that has the same power source type
and the same wattage rating as the other installed power supply. Additionally, the airflow direction of the
power supply must match or conform to the airflow direction of the installed fan modules. For the airflow
direction used by the switch, see the coloring of the fan modules.
Removing an AC Power Supply
To remove an AC power supply, you must first disconnect the power cable and then remove the module from
the chassis.
Before you begin
• To replace a power supply during operations, you must have a functioning power supply providing power
to the switch while you replace the other power supply. If there is only one power supply installed in the
switch and you need to replace it, install the new power supply in the open slot and power it up before
removing the original power supply.
• Ensure that the chassis is grounded. For grounding instructions, see
Grounding the Chassis, on page 18
.
Step 1
Pull the power cord out from the power receptacle on the power supply to be removed and verify that the
LED turns
off.
The
LED might be on and amber colored to indicate that the input power has been disconnected.
Note
Step 2
Remove the power supply from the chassis by pushing and holding its thumb latch to the left and pulling the power supply
part way out of the chassis.
Step 3
Place your other hand under the power supply to support it while you slide it out of the chassis.
