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 protrusions that could damage fine furniture.
Do not rest the enclosure on unprotected furniture.
6. Remove the front panel from the enclosure.
7. Disconnect any cables from the rear of the existing AAPs.
Carefully pull the cables out through the bottom of the
surface mount enclosure.
8. On the underside of the table, remove the two bolts that
secure the clamshell to the surface mount enclosure
(figure 3-5). Lift the enclosure out of the table.

connectors on the underside of the surface mount
enclosure.
13. Cable the rear of the AAPs that are installed on the front

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.

onto the rear of the front panel
bezel plug-ins.

front panel screw, two spare screws are stored
in the underside of the clamshell.

17. 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”.
