MX2000 DC Power Supply Module (240 V China) Description
The MX2008 supports a DC power system. The 240 V China DC power system operates with nine feeds.
A total of nine feeds are required to fully power the MX2008. Another nine feeds are required to provide
feed redundancy (a total of 18 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,
RCBs in slot 0 and 1, SFBs in slot 0 through 7, and fan trays 0 and 1.
NOTE:
The MX2008 systems configured for DC (240 V China) input power must use only DC
(240 V China) PDMs and DC PSMs. AC and DC PSMs or PDMs must not be mixed 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.
