WARNING
Static electricity can damage switch components. Be sure to wear antistatic
straps before handling hardware modules and disk drives.
On the ARX-2000, the front bezel must be removed before you can replace
the disk drives or the NVRAM battery. The following figure shows the
appearance of the front bezel when installed.

Remove the bezel, as described in the following steps:
1. If necessary, remove any cables still attached to the system.
2. Insert fingers through the two cutouts on the lower half on either
side of the bezel and pull it gently away from the front of the
system.
When you have completed the FRU replacement, re-install the bezel as
follows:
1. Line up the bezel with the switch.
2. Gently push the bezel onto the front of the switch until it clicks into
place.
3. Connect any Ethernet cables, as desired, to the front of the switch.
