Cisco C9610 series smart switches ship with preinstalled power supply modules. This section describes how to remove and install the power supply modules.

Required tools and equipments

To install a power supply unit on a Cisco C9610 switch, you need

Phillips-head screwdriver
10-mm torque driver (with a 3-inch shaft, at a minimum)
Wire-stripping tool
Wire-crimping tool

Remove and reinstall power supply modules

The chassis supports field-replaceable and hot-swappable AC-input and DC-input power supply modules. You can install a mix of AC-input and DC-input modules in the chassis. This section describes how to remove and install both kinds of modules and safety warnings to adhere to.

In redundant mode, you do not have to power down the switch to replace or upgrade the power supplies.
In combined mode, the module is still hot-swappable as long as the difference between total output power and the total used power is greater than the capacity of the module being removed.

Total output power: Total used > Capacity of power supply module being removed.

	7.	Follow the steps to install the power cord retainer, to hold it in place and avoid accidental removal. Fix the strap in the power cord retainer to the power supply module, to hold the clamp in place. Slide the retainer clamp around the power cord and position the retainer closest to the power supply. Depending on the width of the power cord, adjust the size of the retainer clamp, if required. Press the tabs on the retainer clamp towards each other to secure the power cord.
	8.	Set the power switch to the ON (\|) position

What to do next

Connect the power supply to the power source.

Connect to an AC power source

Procedure

	1.	Prior to connecting the power supply to a power source, ensure that the chassis is properly grounded.
	2.	Plug the power cable into the AC power receptacle on the power supply module.
	3.	Plug the other end of the power cable into a power source supplied by the data center. Note When using redundant mode, connect each power supply to a separate power source.
	4.	Verify that the power supply is receiving power by checking that the LED is on and is green. For more information about the power supply LEDs and the conditions that they indicate, see Power supply module LEDs. When you first activate the power supply, you can verify the functionality of the LED by checking that LED turns on for a couple of seconds. If the LED is flashing amber or green, check the power connections on the power supply and the power source.

Connect to a DC power source

To connect the DC power supply directly to one or two DC power sources, follow these steps.

Before you begin

Warning

Statement 1022—Disconnect Device

To reduce the risk of electric shock and fire, a readily accessible disconnect device must be incorporated in the fixed wiring.

Note
If you are using combined power mode or power supply redundancy mode, connect all the power supplies in the chassis to the same power source. If you are using input source redundancy mode or full redundancy mode, connect half the power supplies to one DC power source and the other half of the power supplies to another DC power source.

Verify that the power supply is receiving power by checking that the LED is on and is green.

When you first activate the power supply, you can verify the functionality of the LED by checking that LED turns on for a couple of seconds. If the LED is flashing amber or green, check the power connections on the power supply and the power source.

Verify the power supply installation

Procedure

	1.	Verify the power supply operation by checking the power supply’s front-panel LED. See Power supply module LEDs.
	2.	Check the power supply and system status from the system console by entering show power command in privileged EXEC mode. `Switch# show power`
	3.	If the LEDs or show power command output indicate a power problem or other system problem.

Remove and reinstall power supply blanks

If a power supply bay in a chassis is unused, you must cover it with a power supply blank cover to maintain proper airflow through the chassis. Part number of the power supply blank is C9606-PWR-BLANK=.

Warning

Statement 1029—Blank Faceplates and Cover Panels

Blank faceplates and cover panels serve three important functions: they reduce the risk of electric shock and fire, they contain electromagnetic interference (EMI) that might disrupt other equipment, and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.
