Insert the AC power cord couplers into input
1
and input
2
on the PSM (see
Figure 23 on page 25 ).
CAUTION: One input on each AC PSM must be powered by a dedicated
power feed derived from feed A. and the other input on each PSM must
be powered by dedicated power feed derived from feed B.
This configuration provides the commonly deployed A/B feed redundancy
for the system. For example, you can connect input
1
on each AC PSM to
feed A, and input
2
on each AC PSM to feed B.
