PRELIMINARY
Connecting AC Power to a
Dual-SP Storage System
Before You Start
To complete this procedure, you will need
❑ The sense cable, which is the serial cable that shipped with the UPS. This cable allows
Navisphere Express to monitor UPS status.
❑ The AC power cables appropriate to your power source. These cables shipped with the
storage system.
CAUTION
You must connect the UPS serial cable to the purple UPS (+ -) port on SP A. This
connection is required for write-cache operation, and allows Navisphere Express
to monitor the UPS. A standard null-modem or other service serial cable may
look identical to the unique serial cable supplied with the UPS, but it will not
work. Be sure to use the unique serial cable that came with the UPS.
STEP 1. Plug one end of the UPS serial cable into the serial port on the UPS (Figure 43).
STEP 2. Plug the free end of the UPS serial cable into the UPS connector (labeled with a +- battery
icon) on SP A (Figure 43).
