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.
