1. Remove the surface mount enclosure. See Removing and
Replacing the Enclosure, steps 1 through 9. Place the
enclosure on a horizontal surface.
2. Insert the new RJ-45 connector bezel plug-ins through the
holes in the bottom of the surface mount enclosure.
3. Snap the interior RJ-45 cable connectors onto the rear of
the bottom RJ-45 connector bezel plug-ins.
4. Connect the internal cables to the inside of the bottom
RJ-45 connectors.
5. Replace the single-outlet internal AC power cord with a
double-outlet AC power cord.
6. Install the second AC connector.
7. Reinstall the surface mount enclosure. See Removing and
Replacing the Enclosure, steps 11 through 19. In steps 12
through 14, install the new front connector panel in place
of the blank panel. In step 15, connect the AC cables to
both AC connectors.
Replacing the Gas Lift
The gas lift that raises the surface is rated for 100,000 opening
and closing cycles. An enclosure with many cables connected or
an enclosure with a brass top panel may require a stronger gas
lift than the standard 10-lb lift (see Routing Template and
Replacement Parts in appendix A, Specifications, Part Numbers, and
Accessories for part numbers of the 12-lb and 15-lb gas lift.
Replace the gas lift as follows:
Ensure that AC power is disconnected before
servicing the HSA unit.
1. Remove the surface mount enclosure. See Removing and
Replacing the Enclosure, steps 1 through 9. Place the
enclosure upside-down on a horizontal surface. To protect
the finish, place the enclosure on a soft cloth.
2. Open and close the top panel as necessary to access the
center lifting platform (figure 3-5). Remove the four
screws that secure the top panel bracket to the lifting
platform.
CAUTION
With the top panel bracket detached from the lifting
platform, the bracket will be floppy atop the gas lift.
Ensure that the bracket does not bang into the top
flange. Marring of the soft surface of the flange
may result
3. Turn the enclosure frame rightside-up.

4. Remove and retain the 9/32” nut and bolt that secure the
gas lift to the top panel clevis. Lift the panel and clevis off
of the gas lift and set it aside on the bracket flanges.
5. Turn the gas lift counterclockwise until the lift comes free
of the frame clevis nut at the bottom of the enclosure
