Extra SPS for redundancy
An additional SPS can be added for redundancy. When only one SPS is used, the AC power
out connectors for the SPS supply AC power to both SP A and SP B.
It is important to cable each SPS so that it connects completely to either the A side or the B
side. For example, if you are looking at the SPSs from the rear, they should be configured
as:
◆ SPS A (rear, right side)—Power-out and sense (management) cables connected to the
SP A power supply.
◆ SPS B (rear, left side)—Power-out and sense (management) cables connected to the
SP B power supply.
Note: If an SPS is cabled with the SPS sense (management) cable going to the power
supply on SP A and the power-out cable going to the power supply on SP B (or vice versa),
an error condition will occur when the SPS is tested or when it is charging.
Looking from left to right, Figure 14 shows an example of the rear view of a dual 1U SPS (B
and A, respectively).
