Replacing the Bezels
The HSA 822 ships with RJ-45 connector bezel plug-ins in a
variety of colors and a black, blank bezel. Replace a bezel as
follows:
1 . Remove the top and bottom screws on the right and left
sides of the AAP panel (figure 3-1). Retain the screws. Lift
the panel away from the enclosure as far as the connected
cables allow and then allow the panel to dangle,
supported by its connected cables.
The center screws on each side of the AAP panel do not
fasten the AAP panel in place. They secure the
AC power outlet.
Ensure that the edges of the AAP panels do not scratch
the finished surface of the top panel flange when
removing the panels.
2 . With a tweeker, push down on and
gently twist on the front of each RJ-45
connector detent to disconnect the
connector from the rear of the AAP panel
plug-in.
3 . Pinch the top and bottom bezel detents
together and push the bezel through the
AAP panel.
4 . Snap a replacement bezel in place. If
necessary, replace the connector icon by
prying the old icon off of the connector plug-in with a
tweeker (figure 3-3) and snapping a new icon in place.

5 . Replace the AAP panel in the surface mount enclosure and
secure it in place with the screws removed in step 1. If you
lose an AAP panel screw, four spare screws are stored in
the underside of the enclosure.

Removing and Replacing the Enclosure
The procedures for replacing the gas lift and adjusting the
levelling of the top surface require removing the HSA 822 from
the table. Remove and replace the surface mount enclosure for
maintenance as follows:
Ensure that AC power is disconnected before
servicing the HSA unit.
1 . On the underside of the clamshell and in the enclosure, cut
the tie wraps that route the AAP cables out of the way.
2 . Disconnect the IEC power cord and RJ-45 connectors from
the underside of the surface mount enclosure.
3 . On both AAP panels, remove the top and bottom screws
on the right and left sides of the AAP panel (figure 3-1,
page 3-2). Retain the screws. Lift the panels away from
the enclosure as far as the connected cables allow and then
allow the panels to dangle, supported by their connected
cables.
The center screws on each side of the AAP panel do not
fasten the AAP panel in place. They secure the AC
power outlet.
CAUTION Ensure that the edges of the AAP panels do not
scratch the finished surface of the top panel flange
or the furniture in which the HSA 822 is installed
when removing the panels.
4 . To ensure that the bottom RJ-45 connectors match up with
the AAP panel RJ-45 connectors when the maintenance is
complete, tag the internal CAT 6 cables to define their
installation location (top or bottom and side A or B).
Also tag the side of the enclosure itself (A or B).
5 . With a tweeker, inside the AAP panels,
push down on and gently twist on the
front of each RJ-45 connector detent to
disconnect the connector from the rear of
the AAP panel plug-in.
6 . Disconnect any cables from the rear of
the existing AAPs. Carefully pull the
cables through and out the bottom of the
surface mount enclosure.
7 . Set the AAP panels aside.
