Removing the front bezel and top cover

To install option cards or DIMMs, you must remove the front bezel and the top cover from the gateway.

To remove the front bezel:

1Shut down the VPN Router 2750 using the Web GUI or the CLI, and then unplug it as described in “Shutting down the system to add or replace hardware” on page 62.

Warning: Risk of electric shock

Turn off the VPN Router 2750, and unplug it before you attempt to install an option card or DIMM.

2Use a Phillips screwdriver to turn each of the two screws on the front bezel a quarter turn counterclockwise (Figure 20).
