Prerequisites and Preparation
¡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.)
Varning! Denna varningssymbol signalerar fara. Du befinner dig i en situation som kan leda till personskada. Innan du utför arbete på någon utrustning måste du vara medveten om farorna med elkretsar och känna till vanligt förfarande för att förebygga skador. (Se förklaringar av de varningar som förekommer i denna publikation i appendix "Translated Safety Warnings" [Översatta säkerhetsvarningar] i den installationshandbok som medföljer denna anordning.)
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.

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:
•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.
