Removing and Replacing the Enclosure
Many maintenance procedures require removing the HSA 822M
from the table. Remove and replace the surface mount
enclosure as follows:
1.
Activate the motor to raise the platform and then
disconnect the AC power.
Ensure that AC power is disconnected before
servicing the HSA unit.
When AC power is removed, the platform may sink
partially down into the HSA.
2.
On the underside of the clamshell, cut the tie wraps that
route the AAP cables out of the way.
3.
For both AAP/RJ-45 panels, remove the top and bottom
screws on the right and left sides of the panel (figure 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/RJ-45 panel
do not fasten the AAP/RJ-45 panel in place. They secure
the AC power outlet.
Ensure that the edges of the AAP/RJ-45 panels do
CAUTION
not scratch the finished surface of the top panel
flange or the furniture in which the HSA 822M is
installed when removing the panels.
4.
To ensure that you remate RJ-45 connectors in the proper
position 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/RJ-45
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/RJ-45 panel plug-in.
6.
Disconnect any cables from the rear of
the existing AAPs.
7.
Set the AAP/RJ-45 panels aside.
8.
Disconnect the IEC power cord, the RJ-45
connectors, and the control and status
connector (figure 3-1 on page 3-2, items
) from the connectors on the underside of the HSA.
