Step
Procedure
Comments/References
1
Carefully place the Power
Supplies in the slots in the
Rack, ensuring that the
connector at the back seats
properly. See Table 9 steps 1
and 2 for power supply wiring
details.
Note: It is recommended each
power supply should be
powered from a separate
power source and a power
switch should be installed to
allow for servicing of each
Processor/Supply separately.
2
Set controller communication
ports.
See page 42.
3
Ensure that AC power to the
rack is disconnected.
Carefully place the Controller
Modules in the rack, adjacent
to the Power Supplies.
Fasten them in place with
captured screws at top and
bottom.
Torque to 0,4 -0,5 N.m
(3.5 – 4.4 Lb-In).
ATTENTION:
The CPU battery comes
installed with a plastic tab
protruding from the battery
cover. This tab breaks the
battery circuit. Do not
remove this tab at this time.
Removing the tab before
the controller is configured
can substantially shorten
battery life. Remove the tab
under power after the
controller configuration is
complete.
(For more information, refer to
Battery
