End of Procedure
Cabling the System Monitor
The System Monitor (NT8D22) is used to monitor the temperature, power
supplies, and blower unit in a column. A series of daisy-chained flat-ribbon
cables between each module is used to connect the power supplies and the top
cap thermal sensors to the system monitor located in the pedestal. The flat
cable routes through the square holes in the rear horizontal cable trough.
Figure 63 shows the cabling of the system monitor in a column.
