Removing And Replacing The Enclosure; Replacing The Bezels - Extron electronics HSA 200S User Manual

Maintenance and Modifications
The most probable corrective maintenance procedures for your
HSA 200 or HSA 222 are leveling the top surface and replacing
the gas lifts. Most of the maintenance procedures require
removing the surface mount enclosure from the table.

Removing and Replacing the Enclosure

• The procedure for replacing the bezel in an HSA 222 only
requires removing the HSA from the table.
• The procedure for replacing the gas lift requires removing
the HSA 200 or HSA 222.
• The procedure for levelling the top surface may require
removing the HSA.
Remove and replace the surface mount enclosure for
maintenance as follows:
Ensure that AC power is disconnected before
servicing the HSA unit.
1. Disconnect:
• The IEC power cord
• The RJ-45 connectors from the underside of the surface
mount enclosure
• (HSA 200 models only) Any device plugged into the AC
power outlet
• (HSA 200 models only) The BNC (video) connectors
• (HSA 200 models only) The audio connector
• (HSA 200CE and HSA 200SE only) The power supply
connector
2. Loosen the locking
thumbscrews on the screw
clamps to unlock the clamp.
3. Loosen the screw clamps.
4. Remove the screw clamps on
both sides of the enclosure.
Lift the enclosure from the table.
The flanged edges of the top of the surface enclosure
CAUTION
are bevelled to an ultra-fine thickness of less than
0.04 (4/100)" (approximately 1 mm), and are
therefore very sharp. These edges are also soft and
may be easily nicked or bent. Exercise caution
when handling and mounting the enclosure.
Mishandling may result in injury to the installer or
damage the appearance of the enclosure.

Screw
Clamp
Thumbscrew
The surfaces of the HSA enclosure have screws and other
protrusions that could damage fine furniture. Do not
rest the enclosure on unprotected furniture.
5. Perform the desired maintenance procedure.
6. If the surface is not level, adjust the top surface. See
"Adjusting the Top Panel" in this chapter.
7. Carefully lower the HSA enclosure into the table opening.
8. From the underside of the table, reinstall the screw clamps
on the enclosure at a height at which the clamp will reach
the underside of the tabletop.
9. Snugly tighten the Phillips head screws on the screw
clamps to secure the enclosure to the surface.
CAUTION Overtightening the Phillips head screws on the
screw clamps can bend the clamp's horizontal
flange.
10. Tighten the locking thumbscrews on the screw clamps to
lock the clamp in position.
11. Reconnect all of the connectors removed in step 1.

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.
To change to a different color connector
bezel or if a connector is not needed,
replace the connector bezel plug-in on the
front panel with a bezel of a different
color or a blank plug-in.
If no connector is desired, snap the
interior RJ-45 connector onto the rear of
the blank bezel plug-in to hold it conveniently out of the way.
Retain the removed connector bezel plug-in for later use.
Replace a bezel as follows:
1. (HSA 222 models only) Remove the surface mount
enclosure from the table. See "Removing and Replacing
the Enclosure", steps 1 through 4.
