This section describes recommended practices for safe and effective installation of the hardware described in this document, and includes the following sections:

Safety Recommendations

Preventing Electrostatic Discharge Damage

General Maintenance Guidelines for Cisco Interface Cards

Safety warnings included in this section apply to all Cisco interface cards used on Cisco access routers.


Note Recommendations and warnings for specific interface cards are documented in the chapter specific to the interface card.


Safety Recommendations

To prevent hazardous conditions, follow these safety recommendations while working with this equipment:

Keep tools away from walk areas where you or others could trip over them.

Do not wear loose clothing around the router. Fasten your tie or scarf and roll up your sleeves to prevent clothing from being caught in the chassis.

Wear safety glasses when working under any conditions that might be hazardous to your eyes.

Locate the emergency power-off switch in the room before you start working. If an electrical accident occurs, shut the power off.

Before working on the router, turn off the power and unplug the power cord.

Disconnect all power sources before doing the following:

Installing or removing a router chassis

Working near power supplies

Do not work alone if potentially hazardous conditions exist.

Always check that power is disconnected from a circuit.

Eliminate possible hazards from your work area, such as damp floors, ungrounded power extension cables, or missing safety grounds.

If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself.

Turn off power to the room using the emergency power-off switch.

If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge can damage equipment and impair electrical circuitry. Electrostatic discharge occurs when electronic printed circuit cards, such as those used in Cisco interface cards, are improperly handled and can result in complete or intermittent equipment failure. Always observe the following electrostatic discharge damage (ESD) prevention procedures when installing, removing, and replacing Cisco network modules, Cisco interface cards, Cisco expansion modules, or other electronic printed circuit cards:

Make sure that the router chassis is electrically connected to earth ground.

Wear an ESD-preventive wrist strap, and make sure that it makes good contact with your skin.

Connect the wrist strap clip to an unpainted portion of the chassis frame to channel unwanted ESD voltages to ground.


Caution The wrist strap and clip must be used correctly to ensure proper ESD protection. Periodically confirm that the resistance value of the ESD-preventive wrist strap is between 1 and 10 megohms (Mohm).

If no wrist strap is available, ground yourself by touching the metal part of the router chassis.

General Maintenance Guidelines for Cisco Interface Cards

The following maintenance guidelines apply to Cisco interface cards:

Keep the router chassis area clear and dust-free during and after installation.

If you remove the chassis cover for any reason, store it in a safe place.

Do not perform any action that creates a hazard to people or makes equipment unsafe.

Keep walk areas clear to prevent falls or damage to equipment.

Follow installation and maintenance procedures as documented by Cisco Systems, Inc.

Installing Cisco Interface Cards on the Cisco ICS 7750

This section describes how to install Cisco interface cards on the Cisco Integrated Communication System (ICS) 7750, and contains the following subsections:

Preparing to Install Interface Cards on the Cisco ICS 7750

Installing Interface Cards on the Cisco ICS 7750

Cisco interface cards are installed in the Cisco ICS 7750 through either the multiservice route processor (MRP) or analog station interface 81 (ASI 81) cards. For more information about these cards, see the "Processor Cards Feature Summary" in Cisco ICS 7750 System Description.

The MRP has two interface card slots (slot 0, slot 1) and the ASI 81 has one interface card slot (slot 1).

Preparing to Install Interface Cards on the Cisco ICS 7750

Before installing an interface card into the MRP or ASI 81, perform the following tasks:

Verify that the MRP or ASI 81 card has the minimum Cisco IOS release required to support your interface card.

Determine whether additional voice traffic due to installed voice or voice/WAN interface cards will require additional digital signal processors (DSPs). If additional DSPs are required, install up to two additional packet voice data modules (PVDMs) on each MRP or ASI 81 card to provide more processing power.


Timesaver To configure digital voice ports correctly, any additional PVDMs must be installed before the interface card is installed on the MRP or ASI 81 card, or the Cisco ICS 7750 will not be recognized as a voice port.



Tip To see a list of voice ports on the Cisco ICS 7750, use the Cisco IOS show running-config or show diag commands.


Installing Interface Cards on the Cisco ICS 7750

To install an interface card on an MRP or ASI 81 card for installation into the Cisco ICS 7750, perform the following steps:


Step 1 If the MRP or ASI 81 is already installed in the chassis, back up the card configuration using the ICS System Manager application. For more information on backing up card configurations, refer to the ICS System Manager online help system.

If the MRP or ASI 81 is not installed in the chassis, go to Step 7.


Caution Do not power down the chassis using the power supply switch or by unplugging the power supply. Doing so may cause the Cisco ICS 7750 to lose important configuration data and interrupt any applications or functions running on other cards in the chassis.


Timesaver You do not have to turn off power to the Cisco ICS 7750 for this procedure. If the Cisco ICS 7750 is running, do not power down the entire chassis by using the chassis power supply switch or by unplugging the power supply.


Step 2 Shut down operations on the MRP or ASI 81 card by pressing the SHTDN button on the card faceplate. The status LED on the card blinks; after several minutes, the status LED goes off. Wait for the status LED to go off before continuing to Step 3.

Step 3 Put on an ESD-preventive wrist strap and attach the wrist strap to an unpainted chassis surface to establish a ground.


Caution To prevent ESD damage, handle the cards only by the edges, and use an ESD-preventive wrist strap or other grounding device.

Step 4 Disconnect any cables attached to the front of the interface card and secure them out of the way, using cable ties if necessary.

Step 5 Loosen the lock-down screws at the top and bottom of the MRP or ASI 81 card.

Step 6 Press the upper and lower extractor levers away from the chassis at the same time, disengaging the MRP or ASI 81 card from the Cisco ICS 7750 backplane. Pull the card away from the backplane about 1 inch (2.5 cm) to disengage it from the backplane. Do not completely remove the card from the chassis.


Caution Always use the extractor levers to disengage or seat cards. Failure to use the levers can cause erroneous system error messages indicating a card failure.


Caution Do not use the extractor levers to lift or support the weight of the cards.


Caution Devices on system cards can get hot during operation. To remove a card, hold the card by the faceplate and bottom edge. Allow the card to cool before touching any other part of it or placing it an antistatic bag.

Step 7 If you are replacing an interface card, or if there is a blank interface card faceplate already installed in the MRP or ASI 81 card, use either a number 2 Phillips screwdriver or a small flat-blade screwdriver to remove the interface card or blank faceplate.


Tip Save the blank faceplate for future use.



Note If you remove an interface card while the MRP or ASI 81 is running, the interface card configuration is lost until the system card reboots.


Step 8 Align the new interface card with the guides in the ASI 81 or MRP slot, and slide it gently into the slot. (See Figure 18.)

Figure 18 Installing Interface Cards into an MRP Card

Step 9 Push the interface card into place until you feel its edge connector seat securely into the connector on the MRP or ASI 81.

Step 10 Using a Phillips or flat-blade screwdriver, tighten the interface card mounting screws until the interface card faceplate makes contact with the faceplate on the MRP or ASI 81 card.


Tip If an interface card slot on the ASI 81 or MRP is unoccupied, install a filler panel to enable proper airflow.


Step 11 Align the ASI 81 or MRP with the upper and lower card guides in the chassis slot, and make sure that the extractor levers are in the open position (pointing outward).

Step 12 With the top and bottom edges of the ASI 81 or MRP in the card guides, gently slide the card into the chassis until you feel resistance. Because there are grounding clips near the front and rear of the card guides, you might need to increase the amount of force that you use to get the card past the grounding clips. If you encounter extreme resistance, pull the card out slightly, and push it back in again.

Step 13 Press the upper and lower extractor levers inward at the same time until they lock into their slots. This step firmly seats the ASI 81 or MRP into the chassis.

Step 14 Connect cables to the ASI 81 or MRP interfaces.

Step 15 The status LED on the ASI 81 or MRP blinks green as it boots. Wait until the LED is steady green, and then verify that the interface card installation. See the "Verifying Installation of Interface Cards in the Cisco ICS 7750" section.


Verifying Installation of Interface Cards in the Cisco ICS 7750

To verify that an interface card was installed successfully, check the system card LEDs using Table 3.

Table 3 LEDs Used to Verify Interface Card Installation on the Cisco ICS 7750

LED
Description

Status

Shows the status of the MRP or ASI 81:

Blinks green while the card is booting up.

Green after the power-on self-test (POST) is complete, and the card is operating correctly.

Slot 0

Shows the slot status of an MRP card that has an interface card installed in the slot, or of an 8-port FXS card in the ASI 81:

Green shows that the WIC, VWIC, or VIC is correctly installed in the slot.

Off indicates that no card is installed in the slot, or that a card is incorrectly installed in the slot.

Installing Other Accessories in Cisco Interface Cards

Certain Cisco interface cards support a variety of additional modules, such as small form-factor pluggable modules (SFPs).

Installing and Removing SFPs

SFPs are hot-swappable Ethernet interfaces that can be installed directly into Cisco interface cards. The following Cisco interface card is currently support SFPs:

HWIC-1GE-SFP

This section describes a generic installation and removal procedure. SFPs use various latch designs (see Figure 20) to secure the module in the SFP port.


Note Latch designs are not linked to SFP model or technology type; for information on the SFP technology type and model, see the label on the side of the SFP.


To install an SFP in a Cisco interface card, perform the following steps:


Step 1 Install the interface card in the router. (See the "Installing Cisco Interface Cards in Cisco Access Routers" section.)


Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 125

Step 2 Slide the SFP into the housing on the interface card until it is locked into position. (See Figure 19.) The SFP is designed to prevent improper insertion.


Tip If the SFP uses a bale-clasp latch (see Figure 20), the bale-clasp handle should be on top of the SFP in the closed position for proper seating of the SFP module.


Figure 19 Installing an SFP in Cisco Interface Cards


Caution Do not remove the optical port plugs used on the SFP (gray color in the illustration) until you are ready to connect cabling to the interface card.

Step 3 (For optical SFPs) Remove the plugs from the SC connectors on the SFP.

Step 4 Connect the interface card to the network.


Timesaver If installing the SFP in an uninstalled interface card, install the interface card (see the "Installing Cisco Interface Cards in Cisco Access Routers" section) before connecting the interface card to the network.



To remove a SFP from an interface card, perform the following steps:


Step 1 Disconnect all cables from the SFP.


Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 125

Caution The latching mechanism used on many SFPs locks the SFP into place whenever cables are connected. Do not pull on the cabling in an attempt to remove the SFP.

Step 2 Disconnect the SFP latch. (See Figure 20.)
