Step 6
Verify power settings and connections
1. Verify that the cabinet master (power distribution panel) switches are in the
off position.
2. Verify that the power switch on each SPS is off.
3. For high availability, verify that A and B power cords on each enclosure are
connected to different power strips.
4. Verify that all power connections are correct and fully seated:
•
Standby power supply A (SPS A) connects to the SPS serial port (marked with a
battery symbol) on SP A; SPS B connects to SP B.
•
The AC power cord for power supply (PS) A connects to SPS A, and for PS B
connects to SPS B.
•
The SPSs connect to separate power distribution units (PDUs) in the cabinet.
•
Power/cooling module A in the first DAE3P (EA 0, bus 0) in the system connects
to SPS A, and power/cooling module B in the first DAE3P connects to SPS B.
Subsequent DAE3Ps connect directly to the cabinet’s power distribution units.
Make sure power/cooling modules A and B connect to different PDUs.
5. Connect the cabinet AC power cables to the power outlets in the customer’s
facility.
Connect the power cables on the right and left side of the cabinet to different
branch circuits. All active power cables must be connected to an appropriate power
source. Connecting to only one power source will degrade the system’s high
availability.
