Warning Before you install, operate, or service the system, read the Site Preparation and Safety Guide. This guide contains important safety information you should know before working with the system.

Installing the Power Entry Module

The Power Entry Module (PEM) (see Figure 1) allows you to connect the Catalyst 4006 switch to an external power supply. The PEM is installed on the front panel of the Catalyst 4006 switch chassis.

Figure 1 PEM


Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

Caution Ensure that the external power supply is disconnected from the power source before you install and connect it to the PEM.

Follow these steps to install a PEM in your Catalyst 4006 switch chassis:


Step 1 Using a screw driver, unscrew the two captive screws on the PEM panel.


Note Keep the PEM panel in the event you need to remove the PEM later.


Step 2 Carefully insert the PEM into the slot. Be careful that you align it properly so that the 14-pin connector on the rear of the PEM seats properly into the chassis. (See Figure 2.)

Figure 2 Inserting the PEM into the Slot

Step 3 Tighten the two captive installation screws on the PEM front panel, securing it to the Catalyst 4006 switch front panel.


Installing the External Power Shelf and Power Supplies

The external power supply (see Figure 3) allows you to operate voice-power enabled switching modules in the Catalyst 4006 switch chassis. The external power supply is a single-phase, AC-DC, 1050 watt, -52V output power supply. The external power supply is installed in an external power shelf (see Figure 4) that fits into a standard equipment rack. Up to three external power supplies can be installed in the external power shelf.

Figure 3 External Power Supply

Figure 4 External Power Shelf


Note To use an external power supply, you must first install a PEM. If you have not installed a PEM, see the "Installing the Power Entry Module" section for more information.


Rack-Mounting the External Power Shelf


Note Ensure that you install the external power shelf close enough to your Catalyst 4006 switch so that you can connect all power cords to the PEM and to the power outlet. We recommend that you install the external power shelf directly above your Catalyst 4006 switch or in a directly adjacent rack.


The external power supply is installed in the external power shelf. Follow these steps to install the external power shelf in an equipment rack:


Step 1 Align the mounting holes in the L brackets with the mounting holes in the equipment rack.

Step 2 Secure the external power shelf using four (two per side) 12-24 x 3/4-inch screws through the elongated holes in the L bracket and into the threaded holes in the mounting post. (See Figure 5.)

Figure 5 Installing the External Power Shelf in the Rack

Step 3 Use a tape measure and level to ensure that the external power shelf is installed straight and level.


Installing the External Power Supply

After you have installed an external power shelf in the equipment rack, you can install the external power supplies in the chassis. If you have not installed the external power shelf, see the "Rack-Mounting the External Power Shelf" section.

Follow these steps to install an external power supply:


Step 1 Ensure that the external power supply you are installing is not plugged in to a power outlet or the PEM.

Step 2 Loosen the screws on the attachment plates on the upper left and right corners of the external power supply so you can slide the attachment plates down. (See Figure 6.)

Figure 6 External Power Supply Attachment Plates

Step 3 Grasp the external power supply handle with one hand. Place your other hand underneath to support the bottom of the external power supply, as shown in Figure 7.

Figure 7 Handling an External Power Supply


Caution Use both hands to install and remove external power supplies.

Step 4 Slide the external power supply all the way into the external power shelf bay, aligning the attachment plates with the slots on the top of the external power shelf.

Step 5 Slide each attachment plate up so that the upper edge is wedged into the external power shelf slot and use a screwdriver to tighten the two screws on each attachment plate. (See Figure 8.)

Figure 8 Tightening the Attachment Plates

Step 6 Before you connect the external power supply to a power source, ensure that all site power and grounding requirements described in the Site Preparation and Safety Guide have been met.

Step 7 Plug the 2-pin Molex cord into the external power supply. (See Figure 9.)

Figure 9 Connecting the External Power Supply to the PEM

Step 8 Connect the other end of the 2-pin Molex cord to the PEM.


Note Up to three external power supplies can be connected to one PEM.


Step 9 Plug the IEC power cord into the external power supply. (See Figure 10.)

Figure 10 Connecting the Power Cord

Step 10 Connect the other end of the power cord to an AC-power input source.


Caution In a system with multiple external power supplies, connect each external power supply to a separate AC power source. In case of a power source failure, the second source will probably still be available and can maintain maximum overcurrent protection for each power connection.

Step 11 Verify external power supply operation by checking the power supply front panel LEDs:

The LED labeled INPUT OK is lit.

The LED labeled OUTPUT OK is lit.

Step 12 Check the external power supply and system status from the system console by entering the show system command. For more information on commands, refer to the Command Reference for your switch.

Step 13 If the LEDs or the show system command output indicate a power problem or other system problem, refer to the Catalyst 4003 and 4006 Switch Installation Guide for more information.

Translated Safety Warnings

This section translates to multiple languages the warnings in this installation note. These translated warnings can be used with other documents related to this document.

Faceplates and Cover Panel Requirement


Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

Waarschuwing

Lege vlakplaten en afdekpanelen vervullen drie belangrijke functies: ze voorkomen blootstelling aan gevaarlijke voltages en stroom binnenin het frame, ze bevatten elektromagnetische storing (EMI) hetgeen andere apparaten kan verstoren en ze leiden de stroom van koellucht door het frame. Het systeem niet bedienen tenzij alle kaarten, vlakplaten en afdekkingen aan de voor- en achterkant zich op hun plaats bevinden.

Varoitus

Tyhjillä tasolaikoilla ja suojapaneeleilla on kolme tärkeää käyttötarkoitusta: Ne suojaavat asennuspohjan sisäisille vaarallisille jännitteille ja sähkövirralle altistumiselta; ne pitävät sisällään elektromagneettisen häiriön (EMI), joka voi häiritä muita laitteita; ja ne suuntaavat tuuletusilman asennuspohjan läpi. Järjestelmää ei saa käyttää, elleivät kaikki tasolaikat, etukannet ja takakannet ole kunnolla paikoillaan.

Attention

Ne jamais faire fonctionner le système sans que l'intégralité des cartes, des plaques métalliques et des panneaux avant et arrière ne soient fixés à leur emplacement. Ceux-ci remplissent trois fonctions essentielles : ils évitent tout risque de contact avec des tensions et des courants dangereux à l'intérieur du châssis, ils évitent toute diffusion d'interférences électromagnétiques qui pourraient perturber le fonctionnement des autres équipements, et ils canalisent le flux d'air de refroidissement dans le châssis.

Warnung

Blanke Faceplates und Abdeckungen haben drei wichtigen Funktionen: (1) Sie schützen vor gefährlichen Spannungen und Strom innerhalb des Chassis; (2) sie halten elektromagnetische Interferenzen (EMI) zurück, die andere Geräte stören könnten; (3) sie lenken den kühlenden Luftstrom durch das Chassis. Das System darf nur betrieben werden, wenn alle Karten, Faceplates, Voder- und Rückabdeckungen an Ort und Stelle sind.

Avvertenza

Le piattaforme bianche e i panelli di protezione hanno tre funzioni importanti: Evitano l'esposizione a voltaggi e correnti elettriche pericolose nello chassis, trattengono le interferenze elettromagnetiche (EMI) che potrebbero scombussolare altri apparati e dirigono il flusso di aria per il raffreddamento attraverso lo chassis. Non mettete in funzione il sistema se le schede, le piattaforme, i panelli frontali e posteriori non sono in posizione.

Advarsel

Blanke ytterplater og deksler sørger for tre viktige funksjoner: de forhindrer utsettelse for farlig spenning og strøm inni kabinettet; de inneholder elektromagnetisk forstyrrelse (EMI) som kan avbryte annet utstyr, og de dirigerer luftavkjølingsstrømmen gjennom kabinettet. Betjen ikke systemet med mindre alle kort, ytterplater, frontdeksler og bakdeksler sitter på plass.

Aviso

As faces furadas e os painéis de protecção desempenham três importantes funções: previnem contra uma exposição perigosa a voltagens e correntes existentes no interior do chassis; previnem contra interferência electromagnética (EMI) que poderá danificar outro equipamento; e canalizam o fluxo do ar de refrigeração através do chassis. Não deverá operar o sistema sem que todas as placas, faces, protecções anteriores e posteriores estejam nos seus lugares.

Advertencia

Las placas frontales y los paneles de relleno cumplen tres funciones importantes: evitan la exposición a niveles peligrosos de voltaje y corriente dentro del chasis; reducen la interferencia electromagnética (EMI) que podría perturbar la operación de otros equipos y dirigen el flujo de aire de enfriamiento a través del chasis. No haga funcionar el sistema a menos que todas las tarjetas, placas frontales, cubiertas frontales y cubiertas traseras estén en su lugar.

Varning!

Tomma framplattor och skyddspaneler har tre viktiga funktioner: de förhindrar att personer utsätts för farlig spänning och ström som finns inuti chassit; de innehåller elektromagnetisk interferens (EMI) som kan störa annan utrustning; och de styr riktningen på kylluftsflödet genom chassit. Använd inte systemet om inte alla kort, framplattor, fram- och bakskydd är på plats.
