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.

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 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.

(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
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:
•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).
Power problems •If the yellow Fault LED on the power module
is on:
– Make sure the power switch on the power
module is set to | (On).
– Make sure the power and ground wires are
properly connected to the terminals on the
PEM. Follow the wiring instructions
carefully to ensure that you insert the wires
into the correct openings in the terminal
block. See the “Wiring a DC PEM” section
on page 12 for details.
•If the Miswire LED on the DC PEM is on, the
–48V and return (RTN) wires are reversed. Power
off the PEM, turn off the branch circuit that feeds
power to the Cisco 10005, and reconnect the
wires correctly. (See the “Wiring a DC PEM”
section on page 12 for details.)

FCC Class B Compliance
The equipment described in this manual generates and might radiate
radio-frequency energy. If it is not installed in accordance with Cisco installation
instructions, it might cause interference with radio and television reception. This
equipment has been tested and found to comply with the limits for a Class B
digital device in accordance with the specifications in part 15 of the FCC rules.
These specifications are designed to provide reasonable protection against such
interference in a residential installation. However, there is no guarantee that
interference will not occur in a particular installation.
Modifying the equipment without written authorization from Cisco might result
in the equipment no longer complying with FCC requirements for Class A or
Class B digital devices. In that event, your right to use the equipment might be
limited by FCC regulations, and you might be required to correct any interference
to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it
off. If the interference stops, it was probably caused by the Cisco equipment or
one of its peripheral devices. If the equipment causes interference to radio or
television reception, try to correct the interference by using one or more of the
following measures:
•Turn the television or radio antenna until the interference stops.
•Move the equipment to one side or the other of the television or radio.
•Move the equipment farther away from the television or radio.
•Plug the equipment into an outlet that is on a different circuit from the
television or radio. (That is, make certain the equipment and the television or
radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the
FCC approval and negate your authority to operate the product.
