MX2010 DC Power Supply Module (-48 V) Description

The MX2010 supports a DC power system. The DC power system operates with feeds of 60 A or 80 A
current limited. A total of nine feeds are required to fully power the MX2010. Another nine feeds are
required to provide feed redundancy (a total of 18 60-A or 80-A feeds). In the DC power configuration,
the router contains up to nine DC PSMs located at the rear of the chassis in slots PSM0 through PSM8,
(left to right). The DC PSMs in slots PSM0 through PSM8 provide power to the all router components
including MPCs in slot 0 through 9, CB-REs in slot 0 and 1, SFBs in slot 0 through 7, and fan trays 0, 1, 2,
and 3.
NOTE: The MX2010 systems configured for DC input power must use only DC PDMs and DC
PSMs. You cannot mix AC and DC PSMs or PDMs within a single system.
Up to nine PSMs may be connected in parallel to increase available system power across MPCs as needed
and provide redundancy.
Description
Positive and negative input feeds are connected. PDM is functioning normally.
Positive input feed is not connected or present.
Negative input feed is not connected or present.
Figure 47 on page 117 shows the DC PSM.
