Installing and Removing SFP Modules

This section presents procedures to install and remove fiber-optic and 1000BASE-T SFP transceiver modules.

Installing SFP Modules

These sections describe how to install and remove SFP modules. SFP modules are inserted into SFP module slots on the front of the switch. Field-replaceable SFP modules provide the uplink interfaces, send (TX) and receive (RX).

You can use any combination of rugged SFP modules. Each SFP module must be of the same type as the SFP module on the other end of the cable, and the cable must not exceed the stipulated cable length for reliable communications.

For more information about SFP modules, see Cisco Transceiver Modules.


Warning
Do not insert and remove SFP modules while power is on; an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding. Statement 1087

Caution
Depending on the SFP module you use, the operating temperature limits may be effected. Choose an SFP module appropriate to the installed environment.

Caution
To prevent electrostatic-discharge (ESD) damage, follow standard board and component handling procedures.

Caution
Do not install or remove the LC SFP module with fiber-optic cables attached because of potential damage to the cables, the cable connector, or the optical interfaces in the SFP module. Disconnect all cables before removing or installing an SFP module.

Note
Removing and installing an SFP module can shorten its useful life. Do not remove and insert any module more often than is absolutely necessary.
Installing Fiber Optic SFP Modules

Warning
Class 1 laser product. Statement 1008

To install and cable an optical SFP transceiver uplink port:

  1. Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

  2. Find the send (TX) and receive (RX) markings on the module top.

    On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows that show the direction of the connection, either send or receive (TX or RX).

  3. If the module has a bale-clasp latch, move it to the open, unlocked position.

  4. Align the module in front of the slot opening, and push until you feel the connector snap into place.

  5. If the module has a bale-clasp latch, close it.

  6. For fiber-optic SFP modules, remove the dust plugs and save.

  7. Connect the SFP cables.

Figure 10. Installing an SFP Module

Caution
Do not remove the dust plugs from the fiber-optic SFP module port or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables from contamination and ambient light.

Caution
To comply with GR-1089 intrabuilding lightning immunity requirements, you must use grounded, shielded, twisted-pair, CAT5 cabling.

Note
When connecting to a 100/1000BASE-T-compatible server, workstation, or router, use four twisted-pair, straight-through CAT5 cabling for the SFP transceiver port. When connecting to a 100/1000BASE-T-compatible switch or repeater, use four twisted-pair, crossover CAT5 cabling.

To install a 100/1000BASE-T SFP transceiver:

  1. Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector on the chassis or to a properly grounded bare metal surface.


    Caution
    To avoid ESD damage, handle the SFP by its sides; do not touch the connector pins.

  2. Remove the SFP module from its protective packaging.

  3. Check the markings on the SFP transceiver to verify that you have the correct model for your network.

  4. Position the SFP transceiver in front of the port socket opening


    Note
    Different Cisco devices have different SFP transceiver socket configurations. Your Cisco device might require that the SFP transceiver be installed with the bale-clasp either in a latch-up or a latch-down orientation. Verify that you have the SFP transceiver oriented correctly when you position it in front of the port socket.

  5. With the bale-clasp closed (locked), slide the SFP transceiver into the socket until you feel it snap in place in the socket. You may hear an audible click as the SFP transceiver latch engages in the socket.

  6. Connect the network interface cable RJ-45 plug to the SFP RJ-45 connector.

  7. Observe the port status LED:

    • Green indicates that the SFP transceiver and the target device established a link.

    • Amber indicates that the port is discovering the network topology and searching for loops. This process takes about 30 seconds, and then the LED turns green.

    • Off indicates that the target device might not be turned on, there might be a cable problem, or there might be a problem with the adapter installed in the target device. Refer to Troubleshooting for solutions to cabling problems.

Connecting to SFP Modules

This section describes how to connect to a fiber-optic or 1000BASE-T SFP port. For instructions on how to install or remove an SFP module, see Connecting Devices to the Ethernet Ports.


Warning
Class 1 laser product. Statement 1008

Warning
Do not connect or disconnect cables to the ports while power is applied to the switch or any device on the network because an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed from the switch and cannot be accidentally be turned on, or verify that the area is nonhazardous before proceeding. Statement 1070

Caution
Do not remove the rubber plugs from the SFP module port or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables from contamination and ambient light.

Caution
To prevent ESD damage, follow standard board and component handling procedures.

Before connecting to the SFP module, be sure that you understand the port and cabling guidelines in Installing and Removing SFP Modules. See Cable and Connectors for information about the LC on the SFP module.

Connecting to a Fiber Optic SFP Module

To connect a fiber-optic cable to an SFP module:

  1. Remove the rubber plugs from the module port and fiber-optic cable, and store them for future use.

  2. Insert one end of the fiber-optic cable into the SFP module port.

  3. Insert the other cable end into a fiber-optic receptacle on a target device.

  4. Observe the port status LED:

    • The LED turns green when the switch and the target device have an established link.

    • The LED turns amber while the STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the port LED turns green.

    • If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be a problem with the adapter installed in the target device. See Troubleshooting for solutions to cabling problems

  5. If necessary, reconfigure and restart the switch or the target device

Connecting to a 1000BASE-T SFP Module

Caution
To prevent ESD damage, follow standard board and component handling procedures.

To connect a CAT5 cable to a 1000BASE-T SFP module:

  1. When connecting to servers, workstations, and routers, insert a four twisted-pair, straight-through cable in the RJ-45 connector. When connecting to switches or repeaters, insert a four twisted-pair, crossover cable.


    Note
    When connecting to a 1000BASE-T device, use a four twisted-pair CAT5 cable.

  2. Insert the other cable end in an RJ-45 connector on a target device.

  3. Observe the port status LED:

    • The LED turns green when the switch and the target device have an established link.

    • The LED turns amber while the STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the port LED turns green.

    • If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be a problem with the adapter installed in the target device. See Troubleshooting for solutions to cabling problems.

  4. If necessary, reconfigure and restart the switch or the target device.

Removing SFP Modules

  1. Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

  2. Disconnect the cable from the SFP module. For reattachment, note which cable connector plug is send (TX) and which is receive (RX).

  3. Insert a dust plug into the optical ports of the SFP module.

  4. If the module has a bale-clasp latch, pull the bale out and down to eject it. If the latch is obstructed and you cannot use your finger, use a small, flat-blade screwdriver or other long, narrow instrument.

  5. Grasp the SFP module, and carefully remove it from the slot.

  6. Place the module in an antistatic bag or other protective environment.

Replacing the SD Flash Memory Card

  1. Locate the flash memory card slot on the cable-side of the switch.

  2. Loosen the captive thumb screw. (Be careful not to cross-thread or over-tighten the thumb screw.)

  3. Pull the cover open, and pull the cover tab from the hinge.

  4. Gently push the flash memory card to eject it. Place it in an anti-static bag to protect it from static discharge.

  5. Push the replacement card into the slot, and press it firmly in place. The card is keyed so that you cannot insert it the wrong way.

  6. Place the flash card slot cover tabs into the hinge.

  7. Close the cover, and hand-tighten the screw.

Connecting Devices to the Ethernet Ports

The Ethernet ports use standard RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5, Category 5e, or Category 6 UTP cable. The 10BASE-T traffic uses Category 3 or Category 4 cable.

The autonegotiation feature is enabled by default on the switch. At this setting, the switch ports configure themselves to operate at the speed of the attached device. If the device does not support autonegotiation, you can set the switch port speed and duplex parameters. To maximize performance, either let the ports autonegotiate both speed and duplex, or set the port speed and duplex parameters on both ends of the connection.

For simplified cabling, the automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default. With auto-MDIX enabled, the switch detects the required cable type for copper Ethernet connections and configures the interface accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a Ethernet port, regardless of the type of connected device.

See the switch software configuration guide or the switch command reference on Cisco.com for more information about autonegotiation and auto-MDIX.

If auto-MDIX is disabled, use the guidelines in Cable and Connectors to select the cable for connecting the Ethernet ports to other devices.

When using PoE/PoE+, those ports have the same autonegotiation settings and cabling requirements as those in Connecting Devices to the Ethernet Ports . These ports provide PoE power.

See Cable and Connectors for information on the cables and connectors.

The ports provide PoE/PoE+ support for devices compliant with IEEE 802.3af/at and also provide Cisco prestandard PoE/PoE+ support for Cisco IP Phones and Cisco Aironet Access Points.

On a per-port basis, you can control whether or not a port automatically provides power to a connected IP phone or an access point.

To access an advanced PoE planning tool, use the Cisco Power Calculator on Cisco.com:

http://tools.cisco.com/cpc/launch.jsp

You can use this application to calculate the power supply requirements for a specific PoE/PoE+ configuration. The results show output current, output power, and heat dissipation.


Warning
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key or other means of security. Statement 1072

Caution
Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables to a suitable and safe earth ground before connecting them to the switch or other devices.

Where to Go Next

You can use the default configuration or use any of the management options described in Management Options to change the switch settings.
