Replacing A Power Supply Module; Removing An Ac Power Supply - Cisco Nexus 93360YC-FX2 Hardware Installation Manual

Replacing a Power Supply Module

b) Position the fan module in front of the open fan slot (be sure that the backside of the module with the electrical
connectors is positioned to enter the slot first) and slide the module all the way into the chassis until its front side
comes in contact with the chassis. For the last 0.2 inches (0.5 cm), carefully mount the module onto the chassis
connectors by pushing more firmly, but do not force the module if it does not move further (excessive force can
damage the connectors).
Note
c) Verify that the STS LED turns on and becomes green.
If the STS LED does not turn on, slide the module out of the chassis, and visually check the electrical connectors on
the back side of the chassis for damage. If damaged, contact Cisco Technical Assistance for help. If undamaged,
repeat the previous step to reinstall the module.
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
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
• Ensure that the chassis is grounded. For grounding instructions, see
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.
Note The LED might be on and amber colored to indicate that the input power has been disconnected.
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.

If you are not able to push the module all the way into the slot, carefully slide the module out of the slot
and check its electrical connectors for damage. If damaged, contact Cisco Technical Assistance for help.
If undamaged, repeat this step to reinstall the module.
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.
