Adding or Replacing a DC PEM Set the power switch on the PEM that you are replacing to the 0 (Off) position. If Step 2 you have redundant PEMs, be sure to leave one PEM turned on. Caution Do not power off both of the DC PEMs in a redundant system, or the system shuts and down all data traffic stops.

Blank faceplates (filler panels) serve three important functions: they Warning prevent exposure to hazardous voltages and currents inside the chassis; they confine electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, power modules, and faceplates are in place.

Adding or Replacing a DC PEM Wiring a DC PEM This section provides procedures for connecting a DC PEM to a DC power source. Preparing to Connect Power and Ground Follow these steps to prepare the power and ground wires to be connected to the Cisco 10005 DC PEM.
Page 13
Adding or Replacing a DC PEM Connecting DC Ground When you are installing or replacing the unit, the ground connection must Warning always be made first and disconnected last. To attach the grounding wire to the grounding receptacle on the Cisco 10005 DC PEM, perform these steps: Set the DC PEM power switch to the 0 (Off) position.

Insert the end of the grounding wire into the grounding receptacle, which is the Step 3 bottom receptacle in the terminal block on the PEM Figure 6 Ensure that no copper wire strands are left outside the receptacle. Step 4 Use the screwdriver to tighten the ground screw in the terminal block to a torque Step 5 of 1.5 to 1.8 newton meters (13.28 to 15.93 inch-pounds).
Adding or Replacing a DC PEM Connecting DC Power Only a DC power source that is isolated from AC mains with reinforced Warning insulation, and that complies with the other safety extra-low voltage (SELV) requirements in UL1950, CSA 950 3rd Edition, EN 60950, and IEC950, can be connected to a Cisco 10005 system.

Figure 7 Insert the power lead from the battery –48V power source into the receptacle Step 6 labeled – (negative) on the PEM. The stripped part of the wire must be fully inserted, so that no bare wire is exposed. Use the screwdriver to tighten the terminal screw to a torque of 1.5 to 1.8 newton meters (13.28 to 15.93 inch-pounds).
