Product Description

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.

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:

Warnung

Avvertenza

Advarsel

Dieses Warnsymbol bedeutet Gefahr. Sie befinden sich in einer Situation,
die zu einer Körperverletzung führen könnte. Bevor Sie mit der Arbeit an
irgendeinem Gerät beginnen, seien Sie sich der mit elektrischen
Stromkreisen verbundenen Gefahren und der Standardpraktiken zur
Vermeidung von Unfällen bewußt. (Übersetzungen der in dieser
Veröffentlichung enthaltenen Warnhinweise finden Sie im Anhang mit
dem Titel “Translated Safety Warnings” (Übersetzung der Warnhinweise)
in der diesem Gerät beiliegenden Installationsanleitung.)

Questo simbolo di avvertenza indica un pericolo. Si è in una situazione che
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.

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,
kan du se i vedlegget "Translated Safety Warnings" [Oversatte

Aviso

Este símbolo de aviso indica perigo. Encontra-se numa situação que lhe
poderá causar danos fisicos. Antes de começar a trabalhar com qualquer
equipamento, familiarize-se com os perigos relacionados com circuitos
eléctricos, e com quaisquer práticas comuns que possam prevenir
possíveis acidentes. (Para ver as traduções dos avisos que constam desta

Warning

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.)

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.)

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.
