MX2010 DC Power Distribution Description (-48 V)
Most sites distribute DC power through a main conduit that leads to frame-mounting DC power distribution
panels, one of which might be located at a location near the rack that houses the router. A pair of cables
(one input and one return) connects each set of PDM input terminal studs to the power distribution panel.
The PSMs can be connected to two separate feeds from different sources that are used for feed redundancy.
There are two PDMs located in slots PDM0/Input0 and PDM1/Input1 that are capable of carrying seven
to nine feeds each. Each feed is connected from one source to one PDM and feeds from the other source
to the second PDM of the DC power system. This configuration balances power draw for the system by
using the commonly deployed A/B feed redundancy.
Each system provides N+1 PSM redundancy along with N+N feed redundancy. If both DC feeds are
available, operating power draws from the feed with higher voltage. These feeds are set by the input mode
DIP switch located on the DC PSM (see “MX2010 DC Power Supply Module (-48 V) Description” on
