Product Description

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:

può causare infortuni. Prima di lavorare su qualsiasi apparecchiatura,

occorre conoscere i pericoli relativi ai circuiti elettrici ed essere al

corrente delle pratiche standard per la prevenzione di incidenti. La

traduzione delle avvertenze riportate in questa pubblicazione si trova

nell’appendice, “Translated Safety Warnings” (Traduzione delle

avvertenze di sicurezza), del manuale d’installazione che accompagna

questo dispositivo.

Advarsel

Dette varselsymbolet betyr fare. Du befinner deg i en situasjon som kan

føre til personskade. Før du utfører arbeid på utstyr, må du være

oppmerksom på de faremomentene som elektriske kretser innebærer, samt

gjøre deg kjent med vanlig praksis når det gjelder å unngå ulykker. (Hvis

du vil se oversettelser av de advarslene som finnes i denne publikasjonen,

Prerequisites and Preparation

Cisco 10005 ESR DC Power Entry Module Installation

78-12653-01

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

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.
