Connecting the MX2008 to High-Voltage Power
Installing MX2000 Router High-Voltage Universal (HVAC/HVDC) Power Supply Modules
To install an MX2000 high-voltage second-generation universal (HVAC/HVDC) PSM:
- On the PSM, slide the plastic cover away from the input
mode switch to expose the dual DIP switches. Move the input mode DIP
switch 0 (left switch) to the ON position for the bottom feed INP0 (expected
to be connected), and DIP switch 1 (middle switch)
to the ON position for the top feed INP1 (expected to be connected). If both DIP switches 0 and 1 are turned to the ON position, then both top and bottom feeds are expected
to be connected, (see Figure 1).
In addition, a PSM failure triggers the alarm LED on the craft interface.
Note:The DIP switches are only used to indicate presence of a feed. If both feeds are present, power is always drawn from feed 0. Power will be drawn from feed 1 only if feed 0 fails.

- Using both hands, grasp the handle and slide the PSM straight
into the chassis until the PSM is fully seated in the chassis slot.
Tighten the two captive screws (see Figure 2).
Apply between 10 lb-in. (1.13 Nm) to 12 lb-in. (1.35 Nm)
of torque to each screw. Do not overtighten the screws. Figure 2: Installing an MX2000 Router High-Voltage Universal (HVAC/HVDC) PSM
- Repeat Steps 1 through 7 for installing
PSMs in slots 0, 1, and 2, where required.Figure 3: Selecting Input Feed on the Universal (HVAC/HVDC) Power Supply ModuleNote:
Each PSM slot not occupied by a universal (HVAC/HVDC) PSM must be covered by a PSM blank panel.

Connecting Power to a High Voltage-Powered MX2000 Router with Power Distribution Modules
Before performing DC power procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.
Ensure that you have connected the chassis to earth ground. See Grounding an MX2000 Router.
You connect AC or DC power to the router by connecting the power cord from a universal (HVAC/HVDC) PDM to an AC or DC power source. See MX2000 High-Voltage Universal PDM (MX2K-PDM-HV) Power Cord Specifications for the list of supported power cords.
To connect the DC or AC source power cables to the router:
- Plug the power cord into the power sockets
on the high-voltage second-generation universal (HVAC/HVDC) PDM .
See Figure 1. Apply slight pressure so that the power cord is firmly
seated in the power socket until you feel it engage. As you plug in
each power cord, the power LED for the socket lights up green.Figure 4: Connecting Power to the Universal (HVAC/HVDC) PDM
