MX2010 High-Voltage Universal (HVAC/HVDC) Power Supply Module Description
The MX2008, MX2010, and MX2020 routers support the same power modules AC, DC, 240 V China, and universal PSMs and PDMs.
The MX2010 supports a universal HVAC/HVDC power system. The HVAC/HVDC power system operates with nine feeds. 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 feeds In the HVAC/HVDC power configuration, the router contains up to nine HVAC/HVDC PSMs located at the rear of the chassis in slots PSM0 through PSM8, (left to right). The HVAC/HVDC 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.
The MX2010 systems configured for universal (HVAC/HVDC) input power must use only universal PDMs and PSMs. AC, DC, 240 V China, and universal 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. Figure 1 shows the universal PSM.
The HVAC/HVDC power system is feed redundant. Each universal PSM can be connected to two separate feeds from different sources that are used to provide feed redundancy. The PSM has two independent power trains connected in parallel at the output while each input is connected to its own feed. Power always is drawn from both feeds. There are two PDMs per power system capable of carrying nine feeds each. The bottom PDM in each power cage provides power to INP0 of all PSMs installed in the cage, while top PDM in each power cage provides power to INP1 of all PSMs installed in the cage. Feed connection to the PDMs should be done according to standard TIA-942 “Telecommunications Infrastructure Standard for Data” depending on tiering level. The primary input of the PSM is a dual-redundant feed, INP0 and INP1. Both feeds are active during operation, and always carry current. Two dual-position DIP switches accessible from front panel indicate whether respective input INP0 or INP1 is expected to be connected or not. Set the input mode DIP switch to the on or off position to determine the power supply feeds (see Table 1 and Figure 2). In addition, a PSM failure triggers the alarm LED on the craft interface. Each PDM has an LED per feed indicating whether the feed is active or not, or whether the feed is connected properly. See MX2010 High-Voltage Universal (HVAC/HVDC) Power Supply Module Description.

The universal HVAC/HVDC PSM has one more (third) DIP input switch accessible from the front panel, see Figure 2. This switch indicates the PSM in the system is using the universal (MX2K-PDM-HV) PDM that has 30 A rated power cord. This should be in the ON position.
