Bezels

The HSA 822MS ships with RJ-45/RJ-11 connector bezel plug-

ins in a variety of colors and a black, blank

bezel.

To change to a different color RJ-45 connector

bezel or if an RJ-45 connector is not needed or

desired, replace the connector bezel plug-in on

the AAP/RJ-45 panel with a bezel of a different

color or a blank plug-in. See Replacing the Bezels

in chapter 3.

If no RJ-45 connector is desired, snap

the interior RJ-45 cable onto the rear of

the blank bezel plug-in (shown at

right) to hold it conveniently out of the

way. Retain the removed connector

bezel plug-in for any possible later

use.
