Turning On Housekeeping Power
Use the following procedure to turn on housekeeping power to the system:
Step 1. Verify that the ac voltage at the input source is within specifications for each cabinet being
installed.
Step 2. Ensure that:
The ac breakers are in the OFF position.
The cabinet power switch at the front of the cabinet is in the OFF position.
The ac breakers and cabinet switches on the I/O expansion cabinet (if present) are in the OFF
position.
Step 3. If the complex has an IOX cabinet, power on this cabinet first.
IMPORTANT The 48 V switch on the front panel must be OFF at this time.
Step 4. Turn on the ac breakers on the PDCAs at the back of the each cabinet.
In a large complex, power on the cabinets in one of the two following orders:
9, 8, 1, 0
8, 9, 0, 1
On the front and back panels, the HKP and the Present LEDs illuminate (Figure 3-36).
On cabinet 0, the HKP and the Present LEDs illuminate, but only the HKP LED illuminates on
cabinet 1 (the right cabinet).
