Replacing the Bezels

The HSA 822 ships with RJ-45 connector bezel plug-ins in a variety of colors and a black, blank bezel. Replace a bezel as follows:

1.	Remove the top and bottom screws on the right and left
	sides of the AAP panel (figure 3-1). Retain the screws. Lift
	the panel away from the enclosure as far as the connected
	cables allow and then allow the panel to dangle,
	supported by its connected cables.
	The center screws on each side of the AAP panel do not
	fasten the AAP panel in place. They secure the
	AC power outlet.
	Ensure that the edges of the AAP panels do not scratch
	the finished surface of the top panel flange when
	removing the panels.
2.	With a tweeker, push down on and
	gently twist on the front of each RJ-45
	connector detent to disconnect the
	connector from the rear of the AAP panel
	plug-in.
3.	Pinch the top and bottom bezel detents
	together and push the bezel through the
	AAP 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. Replace the AAP panel in the surface mount enclosure and secure it in place with the screws removed in step 1. If you lose an AAP panel screw, four spare screws are stored in the underside of the enclosure.

Removing and Replacing the Enclosure

The procedures for replacing the gas lift and adjusting the levelling of the top surface require removing the HSA 822 from the table. Remove and replace the surface mount enclosure for maintenance 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 RJ-45 connectors from
	the underside of the surface mount enclosure.
3.	On both AAP panels, remove the top and bottom screws
	on the right and left sides of the AAP panel (figure 3-1,
	page 3-2). Retain the screws. Lift the panels away from
	the enclosure as far as the connected cables allow and then
	allow the panels to dangle, supported by their connected
	cables.
		The center screws on each side of the AAP panel do not
		fasten the AAP panel in place. They secure the AC
		power outlet.
			Ensure that the edges of the AAP panels do not
	CAUTION
			scratch the finished surface of the top panel flange
			or the furniture in which the HSA 822 is installed
			when removing the panels.
4.	To ensure that the bottom RJ-45 connectors match up with
	the AAP panel RJ-45 connectors when the maintenance is
	complete, tag the internal CAT 6 cables to define their
	installation location (top or bottom and side A or B).
	Also tag the side of the enclosure itself (A or B).
5.	With a tweeker, inside the AAP panels,
	push down on and gently twist on the
	front of each RJ-45 connector detent to
	disconnect the connector from the rear of
	the AAP panel plug-in.
6.	Disconnect any cables from the rear of
	the existing AAPs. Carefully pull the
	cables through and out the bottom of the
	surface mount enclosure.
7.	Set the AAP panels aside.
