Step7 If you intend to attach an external alarm monitoring facility to the circuit breaker
alarm terminal block on the power supply, do so at this time. For an illustration
of how the leads from the alarm monitoring facility are connected to the alarm
terminal block, refer to Figure 7-9 in the section entitled “Adding a DC-Input
Power Supply” in Chapter7.
The section in Chapter 1 entitled “Circuit Breaker Alarm Terminal Block”
describes the alarm monitoring facility in greater detail. This facility provides an
overt (visible or audible) indication that an overcurrent (fault) condition has
occurred in the DC-input power supply.
Step8 Verify that the source DC cables from the source DC circuit breaker to the power
supply terminals are properly installed and that the locking washers and nuts are
securely fastened to the terminals.
Step9 Reinstall the plastic safety cover by placing it over the two standoffs and the
knurled thumbscrew on the power supply faceplate, sliding the cover to the left
and downward until it is seated, and hand tightening the knurled thumbscrew.
Step10 Repeat the procedure in Step 1 through Step 8 to connect source DC power to
the second (redundant) DC-input power supply, if one is present.
Caution At this time, do not turn the rotary power switch to the ON (|) position for either
a single or a redundant DC-input power supply.
Step11 Turn on the source DC circuit breaker that services the DC-input power
supply(ies).
You are now ready to start up your Cisco 12008, as described in the following section.
