Handling Port Adapters

Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage.


Note When a slot is not in use, a blank port adapter must fill the empty slot to allow the router or switch to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the installed port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove the blank port adapter.



Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter components or connector pins. Always use an ESD wrist strap when handling equipment. (See Figure 3-1.)

Figure 3-1 Handling a Port Adapter

Online Insertion and Removal

The Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco 7201 router, Cisco 7301 router, and the Cisco 7401ASR router support the online insertion and removal (OIR) of all port adapter modules. You do not have to power down routers when removing and replacing port adapters in the Cisco 7200 series router, Cisco 7200 VXR routers, Cisco 7201 router, Cisco 7301 router, or Cisco 7401ASR router.

For the Cisco 7304 router, you must remove the Cisco 7304 PCI port adapter carrier card before removing or replacing port adapters.

For Cisco 7500 series routers, you must remove the VIP before removing and replacing port adapters.

For Cisco 7600 series routers, you must remove the FlexWAN module before removing or replacing port adapters.


Note As you disengage the port adapter from the router or switch, OIR administratively shuts down all active interfaces in the port adapter.


OIR allows you to install and replace port adapters and service adapters (carrier cards, VIPs and FlexWAN modules) while the router is operating; you do not need to notify the software or shut down the system power, although you should not run traffic through the port adapter you are removing while it is being removed. OIR is a method that is seamless to end users on the network, maintains all routing information, and preserves sessions.


Note After you replace port adapters several times using OIR, SRAM on the routers becomes fragmented. When this happens, the system might not be able to find enough contiguous SRAM to complete initialization at bootup, and you might get an error message that there is not enough memory. If you have been using the OIR feature numerous times and you get a memory error message during initialization of a PA-A6, we recommend that you power off and restart the system.


The following is a functional description of OIR for background information only; for specific procedures for installing and replacing a PA-A6 in a supported platform, refer to the "Port Adapter Removal and Installation" section.

Each PA-A6 has a bus connector that connects it to the router. The connector has a set of tiered pins in three lengths that send specific signals to the system as they make contact with the port adapter. The system assesses the signals it receives and the order in which it receives them to determine if a port adapter is being removed from or introduced to the system. From these signals, the system determines whether to reinitialize a new interface or to shut down a disconnected interface.

Specifically, when you insert a port adapter, the longest pins make contact with the port adapter first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them.

When you remove or insert a port adapter, the pins send signals to notify the system of changes. The router then performs the following procedure:

1. Rapidly scans the system for configuration changes.

2. Initializes newly inserted port adapters or administratively shuts down any vacant interfaces.

3. Brings all previously configured interfaces on the port adapter back to their previously installed states. Any newly inserted interface is put in the administratively shutdown state, as if it was present (but not configured) at boot time. If a similar port adapter type is reinserted into a slot, its ports are configured and brought online up to the port count of the originally installed port adapter of that type.


Note Before you begin installation, read Chapter 2, "Preparing for Installation" for a list of parts and tools required for installation.


Warnings and Cautions

Observe the following warnings and cautions when installing or removing port adapters:

If a port adapter lever or other retaining mechanism (for example, port adapter latch) does not move to the locked position, the port adapter is not completely seated in the midplane. Carefully pull the port adapter halfway out of the slot, reinsert it, and move the port adapter lever or other mechanism to the locked position.

To prevent jamming the carrier between the upper and the lower edges of the port adapter slot, and to ensure that the edge connector at the rear of the port adapter mates with the connection at the rear of the port adapter slot, make certain that the carrier is positioned correctly, as shown in the cutaway illustrations in the "Port Adapter Removal and Installation" section.

Blank Faceplate and Panel Covers Warning

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. Statement 1029

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.

Aviso

Plaquetas vazias e painéis de proteção têm três funções importantes: impedem a exposição a tensões e correntes elétricas perigosas dentro do chassi; apresentam interferência eletromagnética (EMI) que pode danificar outros equipamentos: direcionam o fluxo do ar refrigerado pelo chassi. Não opere o sistema a menos que todas as placas, plaquetas, tampas frontais e tampas traseiras estejam em seu devido lugar.

Advarsel

Blanke frontplader og sidepaneler tjener tre vigtige formål: de forhinder udsættelse for farlig spænding og strøm inde i chassiset, de isolerer elektromagnetisk interferens (EMI), der kan forstyre andet udstyr, og de leder en strøm af kølig luft gennem chassiset. Betjen ikke systemet medmindre alle kort, frontplader, sidepaneler og bagpaneler er på plads.

Cisco 7304 PCI Port Adapter Carrier Card—Removing and Installing a Port Adapter

You can install one single-width port adapter in a Cisco 7304 PCI port adapter carrier card. This section provides step-by-step instructions for removing and installing a port adapter in a Cisco 7304 PCI port adapter carrier card.


Caution When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the Cisco 7304 PCI port adapter carrier card.


Note If the Cisco 7304 PCI port adapter carrier card is still in the router, you must remove the port adapter carrier card before removing a port adapter.


To remove and install a port adapter in a Cisco 7304 PCI port adapter carrier card, refer to Figure 3-2 and do the following:


Step 1 To remove the port adapter from the Cisco 7304 PCI port adapter carrier card, turn the port adapter lock from its locked and horizontal position shown in A of Figure 3-2 to its unlocked and vertical position shown in B of Figure 3-2.

Step 2 Ensure that the cables are disconnected from the port adapter before removing the Cisco 7304 PCI port adapter carrier card from the chassis.

Step 3 Grasp the handle of the port adapter and pull the port adapter from the Cisco 7304 PCI port adapter carrier card.

Step 4 To insert the port adapter in the Cisco 7304 PCI port adapter carrier card, locate the guide rails inside the Cisco 7304 PCI port adapter carrier card that hold the port adapter in place. They are at the top left and top right of the port adapter slot and are recessed about an inch, as shown in C of Figure 3-2.

Step 5 Carefully slide the port adapter in the Cisco 7304 PCI port adapter carrier card until the port adapter makes contact with the port adapter interface connector. When fully seated, the port adapter front panel should be flush with the face of the Cisco 7304 PCI port adapter carrier card.

Step 6 After the port adapter is properly seated, turn the port adapter lock to its locked and horizontal position, as shown in A of Figure 3-2.


Figure 3-2 illustrates how to remove and install a port adapter in a Cisco 7304 PCI port adapter carrier card.

Connecting Port Adapter Cables

The PA-A6 interfaces provide an interface to ATM switching fabrics for transmitting and receiving data at rates of up to 155 Mbps bidirectionally. The single-mode intermediate-reach and multimode interfaces connect to the SONET/SDH, 155-Mbps multimode or single-mode optical fiber.

For SONET/SDH multimode and single-mode connections, use one duplex SC connector or two simplex SC connectors. Be sure to remove the dust covers from each connector before installing new cables.

E3 or T3 Connections

To connect an ATM E3 or T3 port to the network, use the following procedure:


Step 1 Attach the appropriate coaxial cable directly to the receptacle on the router. (See Figure 3-3.) For cable information, see Table 1-3 on page 1-5.

Step 2 Attach the network end of the coaxial cable to the external E3 or T3 equipment.


Figure 3-3 Attaching a PA-A6 Interface Cable—Coaxial Cable Connector Shown

OC-3c Connections

To connect an ATM OC-3c/STM-1 port to the network, use the following procedure:


Step 1 Attach the appropriate optical fiber cable directly to the receptacle on the router. (See Figure 3-4.) For cable information, see Table 1-3 on page 1-5.

Step 2 Attach the network end of the cable to an external DSU (an ATM network).


Figure 3-4 Attaching a PA-A6 Interface Cable—Duplex Cable Connector Shown


Note Figure 3-4 shows a cable with one duplex SC connector; however, you could also use two cables with one simplex SC connector on each. If you do use separate cables with single SC connectors, you must observe the proper relationship between the transmit (TX) and receive (RX) receptacles on the PA-A6.
