Cisco 7606-S DC Power Supply Configurations


The Cisco 7606-S router accepts two DC power supplies:

2700 W DC-input power supply

4500 W DC-input power supply

You can configure the DC power supplies in the Cisco 7606-S router as follows:

2700 W DC-input power supplies in both shelves.

4500 W DC-input power supplies in both shelves.

A 2700 W DC-input power supply in the upper shelf and a 4500 W DC-input power supply in the lower shelf.

To configure the Cisco7606-S V01 and the Cisco7606-V V02 chassis to use the 2700 W DC-input power supply and the 4500 W DC-input power supply, you must use the booster bracket (Part Number 800-31261-01) and the slim bracket (Part Number 700- 26979-01).

The PID for the slim bracket is KIT-MNTG-4500W06S= .

The PID for booster bracket is KIT-MNTG-2700W06S=.

Identifying Chassis Version in the Supported Line Card

You can use either of the following methods to identify the chassis version in the supported router:

Product Identification Label on the router: - Displays the labels of all the supported chassis. For example, the PID label Cisco7606-S V01 specifies that the chassis version is 01.

Show inventory command in the command line interface: - Displays the version ID of all the supported chassis.


Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing.

Cisco 7606-S V01 Configuration with Two 2700 W DC Power Supplies

This chassis uses booster bracket (Part Number 700-23386-01) to support the power supplies. You do not have to change anything.

Cisco 7606-S V01 Configuration with Two 4500 W DC Power Supplies


Note This configuration requires you to remove the old booster brackets (Part Number 700-23386-01 ) and replace them with the slim brackets (Part Number 700- 26979-01). To do this, proceed as follows:



Step 1 Remove the power supplies as described in Removing PWR-2700-DC Power Supply from a Cisco 7606-S Router.

Step 2 Remove the two screws (Part Number 48-2030-01) securing the bracket (Part Number 700-23386-01) at the top slot and remove the bracket. See Figure E-1.

Step 3 Remove the two screws (Part Number 48-2030-01) securing the bracket (Part Number 700-23386-01) at the lower slot and remove the bracket. See Figure E-1.

Step 4 Use the screws (Part Number 48-2030-01) removed in Step 1 to install the slim bracket (Part Number 700-26979-01) at the top slot. See Figure E-2.

Step 5 Use the screws (Part Number 48-2030-01) removed in Step 2 to install the slim bracket (Part Number 700-26979-01) at the bottom slot. See Figure E-2.

Step 6 Install the 4500 W DC in the upper and lower shelves as described in Installing a PWR-4500-DC Power Supply in a Cisco 7606-S Router.

Cisco 7606-S V01 Configuration with a 2700 W DC Power Supply and a 4500 W DC Power Supply

This configuration requires you to remove the booster brackets (Part Number 700-23386-01) and replace them with the slim brackets (Part Number 700- 26979-01) . To do this, proceed as follows:


Step 1 Remove the power supplies as described in Removing a DC-Input Power Supply.


Note When you are using a PWR-2700-DC and a PWR-4500-DC, you must install the PWR-4500-DC supply in the lower slot.


Step 2 Remove the two screws (Part Number 48-2030-01) securing the bracket (Part Number 700-23386-01) at the top slot and remove the bracket. See Figure E-1.

Step 3 Remove the two screws (Part Number 48-2030-01) securing the bracket (Part Number 700-23386-01) at the lower slot and remove the bracket. See Figure E-1.

Step 4 Use the screws (Part Number 48-2030-01) removed in Step 1 to install the slim bracket (Part Number 700-26979-01) at the top slot. See Figure E-2.

Step 5 At the top slot, use three screws (Part Number 48-2454-01) to install the booster bracket (Part Number 800-31261-01) . See Figure E-3.

Step 6 Install the 2700 W DC power supply in the top slot as described in Installing a PWR-2700-DC Power Supply in a Cisco 7606-S Router.

Step 7 Install the 4500 W DC in the lower shelves as described in Installing a PWR-4500-DC Power Supply in a Cisco 7606-S Router.

Cisco 7606-S V02 Configuration with Two 2700 W DC Power Supplies

This configuration requires you to do nothing as this version of the Cisco 7606-S router already has the slim brackets (Part Number 700- 26979-01) and the booster brackets (Part Number 800-31261-01).

Cisco 7606-S V02 Configuration with Two 4500 W DC Power Supplies

This configuration requires you to remove both upper and lower booster brackets 800-31261-01.


Step 1 Remove the power supplies from the top slot and the lower slot as described in Removing PWR-2700-DC Power Supply from a Cisco 7606-S Router.

Step 2 Remove three screws (Part Number 48-2454-01) securing the booster bracket (Part Number 800-31261-01) at the top slot. See Figure E-4.

Step 3 Push the booster bracket (Part Number 800-31261-01) backward and then lift and remove it from the chassis.

Step 4 Remove three screws (Part Number 48-2454-01) securing the booster bracket (Part Number 800-31261-01) at the bottom slot. See Figure E-4.

Step 5 Push the booster bracket (Part Number 800-31261-01) backward and then lift and remove it from the chassis.

Step 6 Install the 4500 W DC in the top slot as described in Installing a PWR-4500-DC Power Supply in a Cisco 7606-S Router.

Step 7 Install the 4500 W DC in the lower slot as described in Installing a PWR-4500-DC Power Supply in a Cisco 7606-S Router.
