Maintenance and Modifications

The HSA surface mount enclosures can be modified in the future to replace an AAP or to change the color or appearance of the bezel plug-ins. The most probable corrective maintenance procedures required are leveling the top surface and adjusting its height and replacing the gas lift. Most of the maintenance procedures require removing the surface mount enclosure from the table.

Replacing an AAP

Replace one or more AAPs 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.	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.

Remove two

Allen screws on each side.

3.	Disconnect any cables from the rear of the AAPs that are to
	be replaced. If a cable is no longer required in your
	system, carefully pull the cable out through the bottom of
	the surface mount enclosure and the clamshell.

4.	Remove the AAP(s) to be replaced from the front panel by
	unscrewing the nuts on the rear of the panel that fasten the
	plates to the faceplate (figure 3-2).

5.	Cable the rear of the AAPs to be installed before attaching
	the AAPs to the enclosure. Route the cables through the
	hole in the underside of the surface mount enclosure and
	connect them to the rear of the AAPs. If applicable, refer
	to the cabling information in the AAP documentation.
6.	Insert each AAP’s screws through the holes in the AAP
	opening of the front panel. Secure each AAP to the
	enclosure with the provided captive washers and #4-40
	nuts.
7.	Replace the front panel in the surface mount enclosure and
	secure it in place with the hex head screws removed in
	step 2. If you lose a front panel screw, two spare screws
	are stored in the underside of the clamshell.
8.	To prevent wear and tear caused by cable movement,
	secure the AAP cables underneath the table. See “Routing
	the AAP Cables” in chapter 2, “Installation”.
