Cisco Systems 12012 manual Checking the Installation

Removing and Replacing a Card Cage Assembly

Note The captive jackscrew is used to align and draw the power supply connector into the backplane connector. To prevent connector alignment problems, apply even pressure on the power supply handle as you turn the captive jackscrew.

Step 4 Keep one hand on the power supply handle and apply even pressure to the power supply as you turn the captive jackscrew clockwise (insert) using a 10-mm nutdriver or flat-blade screwdriver. Do not overtighten the jackscrew.

Note All electrical connections between the power supply and the backplane are made automatically when the power supply is fully inserted in the power supply bay.

Repeat Step 2 through Step 4 for a second DC-input power supply.

Step 5 Turn on the source DC circuit breaker servicing the DC-input power supply. Do not turn on the power supply power switch at this time.

Proceed to the next section to verify the installation

Checking the Installation

To complete the installation, perform a check of all connections, then power up the system.

Follow these steps to restart the system and verify that the system restarts successfully:

Step 1 Check the following components to make sure they are secure:

•Line cards are fully inserted in the slots and all captive screws are tightened.

•Vertical cable brackets are attached to their respective line cards and all captive screws are tightened.

•Interface cable connections are secured.

•Interface cables are routed neatly through the cable-management system.

•Any empty card slots or power supply bays are filled with card blanks or power supply blanks.

•Power supplies are fully inserted in the bays and the captive screws are tightened.

•Power supply cables are fully connected to the power supplies and the power source, and secured with appropriate strain relief.

•Front covers are installed on the DC-input power supplies.

•The air deflector in the lower card cage is down, resting on its stops.

•The air filter tray is up and the two captive screws are tightened.

Step 2 Ensure that a console terminal is connected to the RP console port and turned on, or that you have a remote login to the router from another device through a telnet session. (You will need to check the startup banner and displays to ensure that the system restarts properly and that all the interfaces reinitialize in the proper state.)
