b. If the card cage you are removing is in the column with the master
system monitor (should be column 0):
On the master system monitor (column 0), disconnect the RJ11 cable to J3,
then the cable to J6, then pull the system monitor out of the slot.
c. If the card cage you are removing is in the column with a slave
system monitor (should be column 1):
On the master system monitor (column 0), disconnect the RJ11 cable to J3,
then the cable to J6, then pull the system monitor out of the slot.

CAUTION
Service Interruption
If the system monitors are not removed, the system
may shut down.
7 Follow the appropriate step below to turn off power to the module:
a. With AC power, set the main circuit breaker for the column to OFF
(down) in the rear of the pedestal.
DANGER OF ELECTRIC SHOCK
Due to hazardous voltage in ac-powered systems,
power to the entire column must be shut down. This
shuts down all functions in the column including the
network group in that column. Relocate essential
services from this group before proceeding.
b. With DC power, set the switch on the NT6D41 CE Power Supply
to OFF (down). Set the circuit breaker for just this module to OFF
(down) in the rear of the pedestal. (All other modules in the column
retain power.)
