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.
8 . On the underside of the table, remove the two bolts that
secure the clamshell to the surface mount enclosure
(figure 3-4). Lift the enclosure out of the table.
9 . Remove and retain the four screws in the corners of each
side surface of the enclosure shroud “cube”. Remove the
two halves of the shroud.
You do not need to 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.
10 . Perform the desired maintenance or modification
procedure.
11 . If the surface is not level or the top panel is not level with
the flange, adjust the top surface. See Adjusting the Top
Surface in this chapter.
12 . Connect the appropriate cables to the rear of the AAPs
installed on the AAP panels. 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 AAP panel bezel plug-ins in
the locations identified by the
tags.
