This chapter describes and illustrates how to install DC fuse panels in Cisco AccessPath-TS and AccessPath-TS3 Model 530 Integrated Access Systems. Use this document with the Cisco AccessPath-TS3 Model 530 Integrated Access System Hardware Installation Guide and with the Regulatory Compliance And Safety Information Document that accompanied your system.
The DC fuse panels provide either single or multiple DC power feeds for your system. Each side of a DC fuse panel can accept 50 amps of continuous input power at -48 volts DC. If multiple feeds are used, a common ground is required for safe operation.
If an system is configured for DC power, the power is supplied to the shelves through 2 DC fuse panels (see Figure 1-1), which are mounted at the top of the AccessPath rack. The DC fuse panels are shipped with the Cisco AccessPath-TS Integrated Access System, but might not be mounted in it. In AccessPath-TS3 Model 530 Integrated Access System, the DC fuse panels are factory-installed.
Note Your DC fuse panel might look slightly different, but its functionality is the same as the panel described and illustrated below.
The DC fuse panels distribute DC power from the primary input feed(s) to all internal power components in the system. Individual GMT-style protection fuses are provided at the power supply level for component protection on each of the internal circuits.
DC fuse panel installation is described in detail in the following sections:
In addition, refer to the DC fuse panel cabling chapter appropriate to your system:

Varoitus Tämä varoitusmerkki merkitsee vaaraa. Olet tilanteessa, joka voi johtaa ruumiinvammaan. Ennen kuin työskentelet minkään laitteiston parissa, ota selvää sähkökytkentöihin liittyvistä vaaroista ja tavanomaisista onnettomuuksien ehkäisykeinoista. Tässä julkaisussa esiintyvien varoitusten käännökset löydät laitteen mukana olevasta Regulatory Compliance and Safety Information -kirjasesta (määräysten noudattaminen ja tietoa turvallisuudesta).
Attention Ce symbole d'avertissement indique un danger. Vous vous trouvez dans une situation pouvant causer des blessures ou des dommages corporels. Avant de travailler sur un équipement, soyez conscient des dangers posés par les circuits électriques et familiarisez-vous avec les procédures couramment utilisées pour éviter les accidents. Pour prendre connaissance des traductions d'avertissements figurant dans cette publication, consultez le document Regulatory Compliance and Safety Information (Conformité aux règlements et consignes de sécurité) qui accompagne cet appareil.
Warnung 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 Dokument Regulatory Compliance and Safety Information (Informationen zu behördlichen Vorschriften und Sicherheit), das zusammen mit diesem Gerät geliefert wurde.
Avvertenza Questo simbolo di avvertenza indica un pericolo. La situazione potrebbe causare infortuni alle persone. 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 nel documento Regulatory Compliance and Safety Information (Conformità alle norme e informazioni sulla sicurezza) 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 vare 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 dokumentet Regulatory Compliance and Safety Information (Overholdelse av forskrifter og sikkerhetsinformasjon) som ble levert med denne enheten.
Aviso Este símbolo de aviso indica perigo. Encontra-se numa situação que lhe poderá causar danos físicos. 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 publicação, consulte o documento Regulatory Compliance and Safety Information (Informação de Segurança e Disposições Reguladoras) que acompanha este dispositivo.
¡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 una traducción de las advertencias que aparecen en esta publicación, consultar el documento titulado Regulatory Compliance and Safety Information (Información sobre seguridad y conformidad con las disposiciones reglamentarias) 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.

Follow these guidelines when working on equipment powered by electricity:
The following items are included with each DC fuse panel:
To install the DC fuse panels, you will also need the following tools and equipment (which are not included):
This section describes how to mount the DC fuse panels in the system cabinet. In the Cisco AccessPath-TS3 Model 530, these panels are factory-installed.
The location of the DC fuse panels is important for proper operation. If equipment is placed too close together, has inadequate ventilation, or is inaccessible, then malfunctions and shutdowns can result and maintenance will be difficult. Plan for access to both the front and rear panels.
The following steps explain how to mount the DC fuse panels in the AccessPath rack:
Note Your DC fuse panel might look slightly different, but its functionality is the same as the panel described and illustrated below. For example, grey DC fuse panels have input circuit breakers; black panels do not.
Step 2 After you secure the rack-mounting brackets to the DC fuse panels, mount the panels at the top of the system rack above the system controller. Use the screws that you provide to attach the DC fuse panels to the side rails of the equipment rack as shown in Figure 1-3.
Note The DC fuse panels must be mounted so that the front panels face the rear of the system cabinet. The fuses and the main circuit breakers of the DC fuse panels should face the same direction as the operating controls of the access servers and the other equipment.
