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 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 2-9) and
snapping a new icon in place.
5. Replace the front panel in the surface mount enclosure and
secure it in place with the Allen screws removed in step 1.
Removing and Replacing the EnclosureThe procedures for changing the top surface, adding a second
connector panel, and replacing the gas lift require removing the
HSA 800 or HSA 802 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 all connector/AAP panels and/or blank panels,
remove the four screws on the right and left sides of the
front panel (figure 3-1). Retain the screws. Lift the panels
away from the enclosure as far as the connected cables
allow.
4. Disconnect any cables from the rear of the existing AAPs.
Carefully pull the cables through and out the bottom of the
surface mount enclosure.
The flanged edges of the top of the surface enclosure
are sharp when the HSA is removed from the table.
Exercise caution when handling to prevent personal
injury.
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). These edges
are soft and can be easily nicked or bent. Exercise
caution when handling and mounting the
enclosure. Mishandling can damage the appearance
of the enclosure.
The surfaces of the HSA enclosure have screws and
other protruding hardware that could damage fine
furniture. Do not rest the enclosure on unprotected
furniture.
5. On the underside of the table, remove the two bolts that
secure the clamshell to the surface mount enclosure
(figure 3-3). Lift the enclosure out of the table.
6. Remove and retain the four screws in the corners of each
side surface of the enclosure “cube”. Remove the two
halves of the shroud.
You need not remove the screws in the center of each
side. They do not secure the shroud in any way; rather,
they provide structural support to the enclosure.
7. Disconnect the 3-prong cable connector on the
interior AC cable (figure 3-4, page 3-7).
8. With a tweeker, inside the front 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 front panel plug-in.
9. Remove the front panel(s) from
the enclosure.
10. Perform the desired maintenance or
modification procedure.
11. If the surface is not level, adjust the top
surface. See Adjusting the Top Surface
Level in this chapter.
12. Cable the rear of the AAPs installed on the front panel(s).
Route the cables through the hole in the underside of the
surface mount enclosure and connect them to the rear of
the AAPs. Refer to the cabling information in the
documentation for the AAP.
13. Snap the interior RJ-45 cable connectors onto the rear of
the RJ-45 front panel plug-ins.
14. Replace the front panel and/or blank panel in the surface
mount enclosure and secure them in place with the screws
removed in step 3. If needed, four spare screws are stored
in the underside of the enclosure.
15. Reconnect the interior AC power cable.
16. Secure the two shroud halves to the enclosure frame with
the eight screws (four per side) removed in step 6.
