Configuring the System Monitor
The master System Monitor (NT8D22) interfaces with a Serial Data Interface
(SDI) port in the column with CPU 0.
Procedure 15
Configuring the System Monitor (NT8D22)
1 Set the baud rate for the SDI port associated with the system monitor to
1200 baud in DTE mode.
2 In the rear of the pedestal, loosen the two retaining screws on the system
monitor and remove it from the PDU.
3 Configure the option switches for each system monitor. (See Circuit Card:
Description and Installation (NN43001-311) for a detailed description of
switch setting options.)
a. For a single-column system, configure the switches as shown in
Table 7.
Note: Connect and cable the system monitor in a single-column system
like a master system monitor for the rest of this procedure.
b. For a multiple-column system, configure the system monitor in the
column with CPU 0 as the master, using the settings shown in
Table 8 and Table 10 on page 154.
c. Configure option switches on slave system monitors as shown in
Table 9 on page 154 and Table 11 on page 156. If CPU 0 and CPU 1
are in different columns, configure the system monitor in the column
