Before you begin

You will need a phillips screwdriver, replacement CLK-7600, and ESD strap to complete this installation.

Caution Always use an ESD wrist strap when handling modules or coming into contact with internal components.

Caution You must remove all power from the Cisco 7600 series router before replacing the clock module.


Replacing the CLK-7600

1) Power down the switch.

2) On the back of the chassis is a large metal cover. Remove the 29 screws which hold this into place. Then remove the rear cover from the chassis. Refer to the following two pictures (not all of the screws are shown):

3) Connect the ESD strap.

4) Internal to the chassis there are 2 additional metal covers. Remove the 5 screws which hold the right cover in place (see photo). Once the screws are removed, lift the cover up and out towards you.

11) Replace the left internal cover and the 2 retaining screws.
