Installing a Clock Module

You can install a clock module without powering down the router. However, you will need to reboot the router to initialize the newly installed clock module.

Note

The router might reboot itself when the installation is complete. Because of this, we recommend that you perform the installation during off-peak hours.

1. Attach an ESD-preventive wrist strap to your bare wrist and connect the metal end to an appropriate ground point on the rack.
2. On the front panel of the E4G-200 router, loosen the screws that hold the cover on the clock module slot.

   Remove the slot cover as shown in the following figure.
