Installing MX2010 DC Power Supply Modules

1. Verify that the power switches on all PSMs are in the off (O) position.
2. 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 (right 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).
   Note

   The DIP switches are used only 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. A PSM failure triggers the alarm LED on the craft interface.

3. 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).

4. Verify that the INP0 and/or INP1 LEDs on the PSM are lit green steadily (see Figure 3) .
   Note

   If you are connecting two feeds, INP0 and INP1, both LEDs on the PSM are lit green steadily.

5. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
6. Move the switch to the on (|) position.
7. Verify that the PWR OK LED is lit green steadily. See MX2010 DC Power Supply Module LEDs for information about MX2010 DC PSM LEDs.
8. Repeat Steps 1 through 7 for installing PSMs in slots 0, 1, and 2, where required.

   Note

   Each PSM slot not occupied by a DC PSM must be covered by a PSM blank panel.
