The DC power supplies in
PEM0
and
PEM1
must be powered by dedicated power feeds
derived from feed A, and the DC power supplies in
PEM2
and
PEM3
must be powered by
dedicated power feeds derived from feed B. This configuration provides the commonly
deployed A/B feed redundancy for the system.

NOTE:
If you plan to operate a maximally configured DC-powered services
gateway, we recommend that you provision 30 A @ -48 VDC for the system.
If you do not plan to provision 30 A @ -48 VDC for the system, you can use the information
in
Table 28 on page 185
and
Table 29 on page 185
to calculate the power consumption @
-48 VDC, and thermal output for various hardware configurations.
