CAUTION:
Do not mix AC and DC PSMs or different PDM types within a single system.
The MX2010 systems configured for three-phase wye AC input power must use only
three-phase wye AC PDMs and three-phase wye AC PSMs. The systems configured
for DC (-48 V) input power must use DC (-48 V) PDMS and PSMs. The systems
configured for DC (240 V China) input power must use DC (240 V China) PDMs and
PSMs. The systems configured for three-phase delta AC input power must use only
three-phase delta AC PDMs and three-phase delta AC PSMs. The systems configured
for single-phase AC input power must use only single phase AC PDMS and single-phase
AC PSMs.

Description
Component
The MX2010 DC power system comprises three components: nine
PSMs, two PDMs,, and a power midplane (PMP). The power system
distributes power from a pool of 22.5K W (20K W for PSM
nonredundant and 2.5 KW reserved for PSM redundancy). This pool
provides power to 10 line-card slots, four fan trays, two CB-REs and
eight SFBs.
DC power system
In the DC (-48 V) power configuration, the router contains up to two
DC PDMs located at the rear of the chassis in slots PDM0/Input0 and
PDM1/Input1 (bottom to top). A minimum of one PDM is required per
system. Two PDMs provide full redundancy. The DC PDM provides a
power interface to nine PSMs. Each DC PDM operates with seven feeds
or nine feeds of either a 60-A or 80-A amp current limit. You can select
the input feed capacity (60-A or 80-A) by setting the DIP switch on the
PDM to the rated amperage of the DC power input feeds. Each DC
PDM has seven or nine DC inputs (–48 VDC and return terminals for
each input).
NOTE:
The selected input capacity applies to all inputs of this PDM.
Selecting 60 A reduces the available power output capacity of the PSMs
supplied by this PDM.
In a redundant configuration, the 7-feed DC PDMs support a total of
fourteen 60-A or 80-A feeds, and the 9-feed DC PDMs support a total
of eighteen 60-A or 80-A feeds.
