Install - Step 2
Connect power cables
Attach the power and SPS serial cables.
1. Verify that any cabinet master switches are in the off position
2. Verify that the power switch on each standby power supply (SPS) is off.
3. If your system was installed and cabled prior to shipment, skip the remainder of
this step and continue with "Connect to site power" (page 25).
4. Connect standby power supply A (SPS A) to the SPS serial port (marked with a
battery symbol) on management module A; SPS B connects to the SPS port on
management module B. Use the sense cable, detailed below.
For high availability, connect the right and left power cords (A and B) to different
power strips/circuits.
5. Connect each SPS to a separate power distribution unit (PDU) in the cabinet, or a
separate site power circuit.
6. Connect the AC power cord for power supply A to SPS A; connect the power
supply B cord to SPS B.
7. Connect DAE-OS power/cooling module A to SPS A. Connect module B to SPS B.
8. For any additional DAEs that you previously connected to a back-end port:
•
Attach the AC power cord for power/cooling module A to the same power
strip that supports SPS A.
•
Connect module B power cords to power source B.
•
Do not connect a DAE other than the DAE-OS to an SPS.
The DAEs will start immediately when connected to active AC power.
If you have additional DAEs that are not connected to the SPE or each other, do
NOT connect them to power circuits now. After you initialize the base system and
confirm its error-free operation, you can power up and configure additional
DAEs.
