Replacing the Bezels
The HSA ships with RJ-45/RJ-11 connector bezel plug-ins in a
variety of colors and a black, blank bezel. Replace a bezel as
follows:
1 . Remove the four hex head screws on the
right and left sides of the front panel
(figure 3-1). Retain the screws. Lift the
panel away from the enclosure.
2 . With an Extron tweeker or a small
screwdriver, push down on and gently
twist on the front of each connector detent
to disconnect the connector from the rear
of the front panel plug-in.
3 . Pinch the top and bottom bezel detents together
and push the bezel through the front 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 . Snap the internal RJ-45 connector onto the back of the front
panel enclosure bezel plug-in.
6 . Replace the front panel in the surface mount enclosure and
secure it in place with the hex head screws that were
removed in step 1.
Removing and Replacing the Enclosure
The procedure for replacing the gas lift requires removing the
HSA 400 or HSA 402 from the table. Adjusting the top surface
level may also require removal of the HSA from the table.
Remove and replace the surface mount enclosure 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 the RJ-45 connectors
from the underside of the surface mount enclosure.
3 . Through the access hole in the rear of the enclosure,
disconnect the 3-prong cable connector on the interior AC
cable (figure 3-4).

4 . On front panel, remove the four hex head screws on the
right and left sides of the front panel (figure 3-1). Retain
the screws. Lift the panel away from the
enclosure as far as the connected cables
allow.
Ensure that the edges of the connector
panels do not scratch the finished
surface of the top panel flange when
removing the panels.
5 . With an Extron Tweeker, push down on and
gently twist on the front of each connector
detent to disconnect the connector from the
rear of the front panel bezel plug-in.
