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:
•Installing a Second DC PEM
•Replacing a DC PEM
•Wiring a DC PEM
•Troubleshooting the Installation
Note 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.
Installing a Second DC PEM
Warning Never install an AC power module and a DC power module in the same chassis.
Follow these step to install a second DC PEM for redundancy.
Caution Do not power off the DC PEM that is providing power to the router. If you do so, all data traffic halts.
Step 1 Put on an antistatic wrist or ankle strap. Connect the strap to the ESD jack on the front of the chassis or to a bare metal surface of the chassis.
Step 2 Ensure that the power switch on the new DC PEM is set to 0 (Off).
Step 3 Insert the new DC PEM (Figure 2) all the way into the power bay to ensure a secure connection to the midplane. Tighten the captive screws.
Figure 2 Inserting a DC PEM
To complete the installation, follow the steps in the "Wiring a DC PEM" section.
Replacing a DC PEM
Warning Never install an AC power module and a DC power module in the same chassis.
Follow these steps to replace a DC PEM:
Step 1 Put on an antistatic wrist or ankle strap. Connect the strap to the ESD jack on the front of the chassis or to a bare metal surface of the chassis.
Step 2 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.
Caution 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.
Step 4 At the terminal block on the PEM that you turned off, use a voltmeter to verify that there is no power present.
Warning Do not allow the test probes of the voltmeter to touch each other while they are touching the power terminals. This is an ENERGY HAZARD to you, to the voltmeter, and to the wires connecting the router to its power source.
Step 5 Use a screwdriver to loosen the screws on the PEM terminal block and remove the wires. Be sure to disconnect the ground (bottom wire) last.
Warning When you are installing or replacing the unit, the ground connection must always be made first and disconnected last.
Step 6 Loosen the captive screws on the DC PEM you are removing and pull the PEM from the chassis using the handle on the faceplate (Figure 3).
Step 7 Ensure that the power switch on the new DC PEM is set to 0 (Off).
Step 8 Insert the new DC PEM all the way into the power bay (see Figure 3) to ensure a secure connection to the midplane. Tighten the captive screws that hold the PEM in place.
If you do no not install a new PEM right away, install a blank faceplate over the empty power bay.
Warning 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.
Figure 3 Removing and Replacing a DC PEM
To complete the installation, follow the procedures in the next section.
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). Trim the end of the insulation so that it is straight, as shown in Figure 4, not slanted.
Figure 4 Stripping Insulation
Warning Remove the covering from exactly the specified length of each wire. If you strip too much of the covering, exposed wire protruding from the terminal block will create an electrical hazard. If you strip too little of the covering, the wire might not make a good contact with the terminal, or it might not be held securely in place in the terminal block.
Step 3 Prepare the other end of each wire to be connected to a DC power source according to the requirements of your site.
Step 4 Connect the power and ground wires to the DC power source.
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.
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).
Figure 5 Positioning the Power and Ground Terminals to Accept Wires
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).
Figure 6 Insert Grounding Wire into Grounding Receptacle
Step 4 Ensure that no copper wire strands are left outside the receptacle.
Step 5 Use the screwdriver to tighten the ground screw in the terminal block to a torque of 1.5 to 1.8 newton meters (13.28 to 15.93 inch-pounds). (Tighten in a clockwise direction.) To avoid breaking the screw, do no exceed 2.3 newton meters.
Step 6 Pull on the wire to ensure that it is held firmly in place.
Step 7 Make sure that the other end of the wire is connected to ground at the DC power source.
Step 8 If you are connecting two power sources to the Cisco 10005 ESR, repeat this procedure for the second 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.
Follow these steps to connect DC power to the Cisco 10005 ESR. Refer to Figure 7.
Step 1 Ensure that power in the DC circuit is off.
Step 2 Ensure that the PEMs are fully inserted into the chassis and secured with their captive screws.
Step 3 Ensure that the circuit breaker on the newly installed PEM is set to 0 (Off).
Step 4 Turn the + and - screws on the new PEM's terminal block counter-clockwise to fully open the terminal connectors. This step ensures that the correct opening is presented for the wires (see Figure 5).
Step 5 Insert the battery return wire from the external power source into the receptacle labeled + (positive) on the PEM (Figure 7). 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). (Tighten the screws clockwise.)
Warning The illustration shows the DC power supply terminal block. Wire the DC power supply as illustrated. The proper wiring sequence is ground to ground, positive to positive, and negative to negative. The ground wire must always be connected first and disconnected last.
Figure 7 Connecting Power to the Terminal Block
Step 6 Insert the power lead from the battery -48V power source into the receptacle 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). (Tighten the screws clockwise.)
Step 7 If you are connecting a second power source, repeat Step 5 and Step 6 to wire the second power source to the second PEM.
Step 8 If your chassis contains only one PEM, install a blank faceplate over the empty power bay.
Warning 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.
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.
Checking the DC Power Connection
Follow these steps to verify that you have correctly connected DC power to the Cisco 10005 chassis:
Step 1 Make sure the circuit breaker on the PEM you have just installed is still set to 0 (Off).
Step 2 Turn on power to the DC circuit.
Step 3 Use a voltmeter to check the voltage at the terminal block on the PEM. Connect the voltmeter's positive contact to the positive (+) terminal on the terminal block. Connect the voltmeter's negative contact to the negative (-) terminal on the terminal block. If the power is wired correctly:
•The voltmeter registers approximately +48VDC to +56VDC (or battery float voltage).
•The yellow Fault LED on the PEM lights.
Warning Do not allow the test probes of the voltmeter to touch each other while they are touching the power terminals. This is an ENERGY HAZARD to you, to the voltmeter, and to the wires connecting the router to its power source.
Step 4 Flip the circuit breakers on the PEMs to | (On). If the power is properly connected:
•The green Power LED lights on each PEM. The green LED indicates that the PEM is making power available to the chassis in the proper voltage range.
•The yellow Fault LED on each PEM goes out.
•The fans start to turn. A slight delay in fan startup is normal.
Troubleshooting the Installation
