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

		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 Philips head screws on the screw
	clamps to secure the enclosure to the surface.
			Overtightening the Philips head screws on the screw
	CAUTION
			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

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.

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.

CAUTION	The flanged edges of the top of the surface enclosure
	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.
