Cisco 10005 ESR DC Power Entry Module Installation
78-12653-01
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.
Figure 1 DC PEM
The Cisco 10005 chassis has two compartments for PEMs. The chassis can
operate with a single PEM; install two PEMs if you require power redundancy.
Prerequisites and Preparation
Before you perform any of the procedures in this guide, we recommend that you:
•Read the safety guidelines in the next section and review the electrical safety
and ESD-prevention guidelines in the Cisco 10005 ESR Hardware
Installation Guide.
•Ensure that you have all of the necessary tools and equipment (see the
“Required Tools and Equipment” section on page 7).
•Have access to the following documents during the installation:

Warning Before working on equipment that is connected to power lines, remove
jewelry (including rings, necklaces, and watches). Metal objects will heat
up when connected to power and ground and the heat can cause serious
burns or weld the metal object to the terminals.
Warning This product requires short-circuit (overcurrent) protection to be provided
as part of the building installation. Install only in accordance with national
and local wiring regulations.
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.
Warning Use copper conductors only.
¡Advertencia!
Este símbolo de aviso significa peligro. Existe riesgo para su integridad
física. Antes de manipular cualquier equipo, considerar los riesgos que
entraña la corriente eléctrica y familiarizarse con los procedimientos
estándar de prevención de accidentes. (Para ver traducciones de las
advertencias que aparecen en esta publicación, consultar el apéndice
titulado “Translated Safety Warnings,” en la guía de instalación que se
acompaña con este dispositivo.)

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.

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.
