Cisco 10005 ESR DC Power Entry Module Installation March 30, 2001 This installation note provides procedures for installing and replacing DC power entry modules (PEMs) in a Cisco 10005 edge services router (ESR).
Product Description Product Description The DC PEM (Figure 1) provides filtering and supplies DC power to the chassis electronics. The DC PEM receives input power (–48 VDC from building centralized power source) through terminal block connections located on the front panel of the PEM.

Prerequisites and Preparation Required Tools and Equipment Table 1 lists the tools and equipment you need to install a DC PEM. Table 1 Tools and Equipment Quantity Description Comments 1 Antistatic wrist or ankle strap with connection cord Prevents damage to equipment from electrostatic discharge (ESD). 1 Number 2 phillips screwdriver — 1 Flat-blade screwdriver. We recommend a torque-limiting screwdriver. Blade should measure 1.0 mm thick by 4.0 mm wide.
Adding or Replacing a DC PEM Adding or Replacing a DC PEM This section describes how to add or replace a DC PEM in a Cisco 10005 chassis. It contains these procedures: Note • Installing a Second DC PEM • Replacing a DC PEM • Wiring a DC PEM • Troubleshooting the Installation Before you perform any of the procedures in this document, be sure that you have connected the chassis to earth ground as described in the Cisco 10005 ESR Hardware Installation Guide.

Adding or Replacing a DC PEM Step 2 Caution Set the power switch on the PEM that you are replacing to the 0 (Off) position. If you have redundant PEMs, be sure to leave one PEM turned on. Do not power off both of the DC PEMs in a redundant system, or the system shuts and down all data traffic stops. Only power off the DC PEM you are replacing. Step 3 Turn off power to the branch circuit that provides power to the PEM that you are replacing.
Adding or Replacing a DC PEM Blank faceplates (filler panels) serve three important functions: they 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. Step 1 Cut the ends of the power and ground wires so that the ends are straight, not slanted. Step 2 Measure and strip 0.43 inches (11 mm) of insulation off the end of each DC power and ground wire (Figure 4).
Adding or Replacing a DC PEM Connecting DC Ground Warning When you are installing or replacing the unit, the ground connection must 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: Step 1 Set the DC PEM power switch to the 0 (Off) position.
Adding or Replacing a DC PEM Step 2 Turn all three screws on the PEM terminal block counterclockwise to fully open the terminal connectors. This step ensures that the correct opening is presented for the wires (Figure 5).

Adding or Replacing a DC PEM Step 3 Insert the end of the grounding wire into the grounding receptacle, which is the bottom receptacle in the terminal block on the PEM (Figure 6).

Adding or Replacing a DC PEM Connecting DC Power Warning Only a DC power source that is isolated from AC mains with reinforced 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. This requirement ensures that in a catastrophic power source fault condition, hazardous voltages are not present on power terminals and connectors.

Adding or Replacing a DC PEM Step 9 Secure the power cabling to the chassis by feeding a tie wrap through the slot on the side of the chassis and binding the cables. Dress the cables so that the fan assembly on the right and the air filter on the left can be removed if necessary.
Adding or Replacing a DC PEM Troubleshooting the Installation Table 2 provides information you can use to solve problems with a DC PEM. Table 2 Troubleshooting the DC PEM Symptom Steps to Take System fails to power on Check that: Power problems • All power leads are connected to the Cisco 10005 and to a power source. • The power switches are in the | (On) position. • The Power LED on the PEM is on (green). • The fan assembly is fully inserted (Fan Status LED is green).
