Installing a Supervisor Engine

This section describes how to safely install a supervisor engine.

Caution To prevent ESD damage, handle the supervisor engine by the carrier edges only.

To install a supervisor engine in the chassis, follow these steps:

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

Note If you are unsure about the correct way to attach an ESD grounding strap, see the "Attaching Your ESD Grounding Strap" section on page C-1 for instructions.

Step 2 Determine the correct slot for the supervisor engine. The following supervisor engines must be installed in these slots:

•Supervisor Engine 2

–Slots 1 and 2 for all chassis

•Supervisor Engine 32

–Slots 1 and 2 for 3- and 4-slot chassis

–Slots 5 and 6 for 6- and 9-slot chassis

–Slots 7 and 8 for 13-slot chassis

•Supervisor Engine 32 PISA

–Slots 1 and 2 for 3- and 4-slot chassis

–Slots 5 and 6 for 6- and 9-slot chassis

–Slots 7 and 8 for 13-slot chassis

•Supervisor Engine 720

–Slots 1 and 2 for 3- and 4-slot chassis

–Slots 5 and 6 for 6- and 9-slot chassis

–Slots 7 and 8 for 13-slot chassis

•Supervisor Engine 720-10GE

–Slots 1 and 2 for 3- and 4- slot chassis

–Slots 5 and 6 for 6- and 9-slot chassis

–Slots 7 and 8 for 13-slot chassis

Note The primary supervisor engine in a redundant supervisor engine configuration, or a single supervisor engine configuration can be installed in either of the two slots.

Step 3 Verify that there is enough clearance to accommodate any interface equipment, such as pluggable transceivers, that you will install directly to the supervisor engine uplink ports.

Step 4 Verify that the captive installation screws are tightened on all modules installed in the chassis.

Note This action assures that the EMI gaskets on all of the modules are fully compressed in order to maximize the opening space for the new or replacement supervisor engine. If the captive installation screws are loose, the EMI gaskets on the installed modules will push adjacent modules toward the open slot, reducing the opening size and making it difficult to install the supervisor engine.

Step 5 If necessary, remove the module filler plate covering the selected slot by removing the two Phillips pan-head screws from the filler plate.

Note If you must remove an existing supervisor engine, refer to "Removing a Supervisor Engine" section.

Step 6 Remove the new supervisor engine from its shipping packaging and from the antistatic shipping bag.

Caution To prevent ESD damage, handle supervisor engines by the carrier edges only.

Step 7 Fully open both ejector levers on the new supervisor engine. (See Figure 3-1.)

Step 8 Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the following two sets of steps:

Chassis with horizontal slots

a. Position the new supervisor engine in the slot. Make sure that you align the sides of the supervisor engine carrier with the slot guides on each side of the chassis slot. (See Figure 3-1.)

b. Carefully slide the supervisor engine into the slot until the EMI gasket along the top edge of the supervisor engine makes contact with the module or cover plate in the slot above it and the supervisor engine ejector levers have both closed to approximately 45 degrees with respect to the supervisor engine faceplate.

Figure 3-1 Positioning the Supervisor Engine in a Horizontal Slot Chassis

c. Using the thumb and forefinger of each hand, grasp the two ejector levers and gently press down to create a small 0.040 inch (1 mm) gap between the supervisor engine's EMI gasket and the module or cover plate above it. (See Figure 3-2.)

Note Do not press down too forcefully on the levers because they will bend and get damaged.

Figure 3-2 Clearing the EMI Gasket in a Horizontal Slot Chassis

d. While gently pressing down, simultaneously close the left and right ejector levers to fully seat the supervisor engine in the backplane connector. The ejector levers are fully closed when they are flush with the supervisor engine faceplate.

Note Failure to fully seat the supervisor engine in the backplane connector can result in error messages.

e. Tighten the two captive installation screws on the supervisor engine.

Note Make sure the ejector levers are fully closed before tightening the captive installation screws.

f. Verify that the supervisor engine STATUS LED is lit.

g. Periodically check the STATUS LED.

•If the STATUS LED changes from orange to green, the supervisor engine has successfully completed the boot process and is now online.

•If the STATUS LED remains orange or turns red, the supervisor engine has not successfully completed the boot process and may have encountered an error.

Note You should install switching-module filler plates (Cisco part number 800-00292-01) in any empty slots to maintain consistent airflow through the switch chassis.

Chassis with vertical slots

a. Position the supervisor engine in the slot. (See Figure 3-3.) Make sure that you align the sides of the supervisor engine carrier with the slot guides on the top and bottom of the chassis slot.

b. Carefully slide the supervisor engine into the slot until the EMI gasket along the right edge of the module makes contact with the module or cover plate in the slot adjacent to it and the module ejector levers have both closed to approximately 45 degrees with respect to the module faceplate. (See Figure 3-4.)

Figure 3-3 Positioning the Module in a Vertical Slot Chassis

Figure 3-4 Clearing the EMI Gasket in a Vertical Slot Chassis

c. Using the thumb and forefinger of each hand, grasp the two ejector levers and exert a slight pressure to the left, deflecting the supervisor engine approximately 0.040 inches (1 mm) creating a small gap between the supervisor engine's EMI gasket and the module or cover plate adjacent to it. (See Figure 3-4.)

Note Do not exert too much pressure on the ejector levers because they will bend and get damaged.

d. While gently pressing to the left on the ejector levers, simultaneously close both levers to fully seat the supervisor engine in the backplane connector. The ejector levers are fully closed when they are flush with the supervisor engine faceplate.

e. Tighten the two captive installation screws on the supervisor engine.

Note Make sure that the ejector levers are fully closed before tightening the captive installation screws.

f. Verify that the supervisor engine STATUS LED is lit.

g. Periodically check the STATUS LED:

•If the STATUS LED changes from orange to green, the supervisor engine has successfully completed the boot process and is now online.

•If the STATUS LED remains orange or turns red, the supervisor engine has not successfully completed the boot process and may have encountered an error.

Note You should install switching-module filler plates (Cisco part number 800-00292-01) in any empty slots to maintain consistent airflow through the switch chassis.

Removing a Supervisor Engine

This section describes how to remove a supervisor engine from the Catalyst 6500 series switch chassis.

Caution During this procedure, wear grounding wrist straps to avoid ESD damage to the module.

Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

Before you remove a supervisor engine, you should first upload the current configuration to a server. This step saves time when bringing the module back online. You can recover the configuration by downloading it from the server to the nonvolatile memory of the supervisor engine. For more information, refer to Chapter 27, "Working with Configuration Files," in the Catalyst 6500 Series Switch Software Configuration Guide or in Chapter 4, Chapter 5, and Chapter 6 in the Catalyst 6500 Series Cisco IOS Software Configuration Guide.

To remove a module from the chassis, follow these steps:

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

Note If you are unsure about the correct way to attach an ESD grounding strap, see the "Attaching Your ESD Grounding Strap" section on page C-1 for instructions.

Step 2 Disconnect any network interface cables attached to the module.

Step 3 Verify that the captive installation screws on all of the modules in the chassis are tight.

Note This step ensures that the space created by the removed module is maintained. If the captive installation screws are loose, the EMI gaskets on the installed modules will push the modules toward the open slot, reducing the opening size and making it difficult to remove the module.

Step 4 Loosen the two captive screws on the module. Make sure that the two captive screws are completely unscrewed from the chassis.

Step 5 Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the following two sets of steps:

Horizontal slots

a. Place your thumbs on the left and right ejector levers and simultaneously rotate the levers outward to unseat the module from the backplane connector. (See Figure 3-5.)

b. Grasp the front edge of the module and slide the module part of the way out of the slot. Place your other hand under the module to support the weight of the module. Do not touch the module circuitry. (See Figure 3-6.)

Vertical slots

a. Place your thumbs on the ejector levers located at the top and bottom of the module, and simultaneously rotate the levers outward to unseat the module from the backplane connector.

b. Grasp the edges of the module, and slide the module straight out of the slot. Do not touch the module circuitry.

Figure 3-5 Opening the Ejector Levers (Horizontal Slot Chassis Shown)

Figure 3-6 Removing the Supervisor Engine (Horizontal Slot Chassis Shown)

Step 6 Place the removed module on an antistatic mat or in an antistatic bag, or immediately reinstall it in another slot.

Step 7 If the slot is to remain empty, install a module filler plate to keep dust out of the chassis and to maintain proper airflow through the chassis. Secure the filler plate in place with two Phillips pan-head screws.

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

Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

Installing Pluggable Transceivers

Supervisor engine uplink ports require that pluggable transceivers be installed in the uplink port sockets. These transceivers are normally shipped separately from the supervisor engine and must be installed after the supervisor engine is installed in the chassis. This section describes how to install the various kinds of pluggable transceivers in the supervisor engine.

Note For additional transceiver installation information, see the transceiver installation note that accompanied the transceiver.

This section contains these topics:

•Installing GBIC Transceivers

•Installing SFP Transceivers

•Installing 10GBASE XENPAK Transceivers

•Installing the 10-Gigabit Ethernet X2 Transceivers

Installing GBIC Transceivers

GBIC transceivers are 1000BASE-X devices that provide an interface between either optical or copper networks and the Supervisor Engine 2 uplink ports. There are multiple types of GBIC transceivers providing a variety of cabling lengths, but all share the same basic form factor.

Note The 1000BASE-T (copper) GBIC has a larger connector housing than the optical GBICs that accommodates the larger RJ-45 connector.

For additional information on GBIC transceiver types, including recommended cabling distances, see the "GBIC Transceivers" section on page A-2. All GBIC transceivers are installed in sockets accessible through the supervisor engine faceplate. This section provides a procedure on how to correctly install GBIC transceivers in the supervisor engine.

Caution We strongly recommend that you do not install or remove the GBIC transceiver with a fiber-optic cable attached to it because of the potential damage to the cable, the cable connector, or the optical interfaces in the GBIC transceiver. Disconnect the network interface cable before removing or installing a GBIC transceiver.

You will need these tools to install the GBIC transceiver:

•Wrist strap or other personal grounding device to prevent ESD occurrences.

•Antistatic mat or an antistatic bag to set the unpackaged GBIC transceiver on.

•Fiber-optic end-face cleaning tools and inspection equipment. For information on inspecting and cleaning fiber-optic interfaces, see the document at this URL:

tap://www.cisco.com/en/US/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml

Caution During this procedure, you must wear a propery grounded ESD grounding strap to avoid ESD damage to the module.

Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

To install GBIC transceivers in an uplink port, follow these steps:

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

Note If you are unsure about the correct way to attach an ESD grounding strap, see the "Attaching Your ESD Grounding Strap" section on page C-1 for instructions.

Step 2 Remove the GBIC transceiver from its protective packaging and verify that the GBIC transceiver is the correct type for your network connection.

Note If this is an optical GBIC transceiver, do not remove optical bore plugs from the GBIC at this time.

Step 3 Grip the sides of the GBIC transceiver with your thumb and forefinger, carefully align the GBIC transceiver with the supervisor engine's uplink port socket opening, and carefully insert the GBIC through the socket flap and slide it into the module GBIC socket. (See Figure 3-7 for installing optical GBICs or Figure 3-8 for installing copper GBICs.)

Note GBIC transceivers have an alignment groove on each side of the transceiver to prevent incorrect insertion. (See Figure 3-9.)

Step 4 Continue sliding the GBIC transceiver into the socket until you hear a click, which indicates that the GBIC is fully mated to the socket connector and that the GBIC is locked into the socket.

Caution You must insert the GBIC straight into the socket (either horizontally or vertically, depending on the orientation of the socket). If you do not install the GBIC correctly or you use excessive force, you will damage the GBIC or the socket.

Installing SFP Transceivers

SFP transceivers provide an interface between an optical or copper network and the following supervisor engine uplink ports:

•Supervisor Engine 32 (8 ports, WS-SUP32-GE-3B and WS-S32-GE-PISA only)

•Supervisor Engine 720 (2 ports, WS-SUP720, WS-SUP720-3B, and WS-SUP720-3BXL)

•Supervisor Engine 720-10GE (2 ports, VS-S720-10G-3C and VS-S720-10G-3CXL)

There are different types of SFP transceivers, but all share the same form factor. For additional information on SFP transceiver types, including recommended cabling distances, see Appendix B. This section provides a procedure on how to correctly install SFP transceivers in the module port socket.

Caution We strongly recommend that you do not install or remove the SFP transceiver with fiber-optic cables attached to it because of the potential damage to the cables, the cable connector, or the optical interfaces in the SFP transceiver. Disconnect the network interface cable before removing or installing an SFP transceiver.

SFP transceiver modules can have three types of latching devices to secure the SFP transceiver in a port socket:

•Figure 3-10 shows an SFP transceiver with a Mylar tab latch.

•Figure 3-11 shows an SFP transceiver with an actuator button latch.

•Figure 3-12 shows an SFP transceiver that has a bale-clasp latch.

Determine which type of latch your SFP transceiver uses before following the installation and removal procedures.

Figure 3-10 SFP Transceiver with a Mylar Tab Latch

Figure 3-11 SFP Transceiver with an Actuator Button Latch

Figure 3-12 SFP Transceiver with a Bale-Clasp Latch

You will need these tools to correctly install the SFP transceiver:

•Wrist strap or other personal grounding device to prevent ESD occurrences.

•Antistatic mat or an antistatic bag to set the unpackaged SFP transceiver on.

•Fiber-optic end-face cleaning tools and inspection equipment. For information on inspecting and cleaning fiber-optic interfaces, see the document at this URL:

http://www.cisco.com/en/US/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml

Note Removing and installing an SFP transceiver can shorten its useful life. Do not remove and insert SFP transceivers more often than is absolutely necessary.

Caution The SFP transceivers are static-sensitive devices. Always use an ESD wrist strap or similar individual grounding device when handling SFP transceivers or coming in contact with modules.

To install an SFP transceiver, follow these steps:

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

Note If you are unsure about the correct way to attach an ESD grounding strap, see the "Attaching Your ESD Grounding Strap" section on page C-1 for instructions.

Step 2 Remove the SFP transceiver from its protective packaging and check the label on the SFP transceiver body to verify that you have the correct model for your network. Find the send (TX) and receive (RX) markings that identify the top side of the SFP transceiver and position the SFP transceiver in front of the socket opening.

Note For optical SFP transceivers, do not remove the optical bore dust plugs until directed to do so.

Note On some SFP transceivers, the TX and RX marking might be replaced by arrowheads pointing from the SFP transceiver connector (transmit direction or TX) and toward the connector (receive direction or RX).

Note Different Cisco modules have different SFP module socket configurations. Your module could have either a latch-up or a latch-down orientation. Ensure that you are installing the SFP transceiver in the correct orientation for your Cisco device.

Step 3 Insert the SFP transceiver into the socket and slide it in until you feel the SFP transceiver connector snap into place in the socket connector. (See Figure 3-13.)

a. On SFP transceivers equipped with bale clasps, you must remove the dust plugs from the optical bores in order to pivot the bale clasp down (unlocked position). Once you have slid the SFP transceiver completely into the socket and the connector is seated, pivot the bale clasp fully up to lock the transceiver in the socket. Immediately replace the dust plug in the optical bores until you are ready to install the network interface cables.

Figure 3-13 Inserting an SFP Transceiver into a Transceiver Socket

Step 4 You are now ready to attach the network interface cables to the SFP transceiver. See "Attaching the Network Interface Cables" section for instructions.

Installing Copper SFP Transceivers

The copper SFP transceiver (see Figure 3-14) has a bale-clasp locking mechanism that secures the transceiver in the module socket. An RJ-45 connector provides the transceiver's interface point to the network.

Figure 3-14 SFP Transceiver (Copper)

2

Bale-clasp latching mechanism shown in the closed (locked) position

   

To install a copper SFP transceiver, follow these steps:

Step 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.

Step 2 Remove the new copper SFP transceiver from its protective packaging.

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

Step 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. Figure 3-15, left view, shows the SFP installed in a latch-up orientation where the bale-clasp latching mechanism pivots up to the closed (locked) position. Figure 3-15, right view, shows the SFP transceiver installed in a latch-down orientation where the bale-clasp latching mechanism pivots down to the closed (locked) position. Verify that you have the SFP transceiver oriented correctly when you position it in front of the port socket.

Figure 3-15 SFP Transceiver Socket Orientations

Step 5 Leave the bale-clasp in the closed (locked) position and push the SFP transceiver into the socket until you feel the SFP transceiver snap into place in the socket. An audible click might also be heard as the SFP transceiver latch engages in the socket. (See Figure 3-16.)

Figure 3-16 Installing the Copper SFP Transceiver (Latch-Up Orientation Shown)

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

Note If, for any reason, you need to remove the copper SFP transceiver from the module socket, observe the following three guidelines:

•Do not attempt to remove the copper SFP transceiver by pulling on the network interface cable.

•Always use the bale-clasp handle to unlock the copper SFP transceiver before attempting to remove the SFP transceiver from the socket.

•Do not grasp the sides of the copper SFP transceiver when you are removing it, because you can damage the SFP transceiver and the socket. Always use the bale-clasp handle when removing a copper SFP transceiver.

Installing 10GBASE XENPAK Transceivers

This section provides a procedure on how to install 10GBASE-X XENPAK transceivers in the uplink ports on Supervisor Engine 32 (WS-SUP32-10GE-3B and WS-S32-10GE-PISA only). There are different types of XENPAK transceivers, but all share the same form factor. For additional information on XENPAK transceivers, including recommended cabling distances, refer to the "10-GB XENPAK Transceivers" section on page A-7.

You will need these tools to install the XENPAK transceiver:

•Small flat-blade screwdriver to loosen or tighten the XENPAK transceiver and XENPAK port cover captive installation screws.

•Wrist strap or other personal grounding device to prevent ESD occurrences.

•Antistatic mat or an antistatic bag to set the XENPAK transceiver on.

•Fiber-optic end-face cleaning tools and inspection equipment. For complete information on inspecting and cleaning fiber-optic connections, refer to the document at this URL:

http://www.cisco.com/en/US/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml

Caution During this procedure, wear grounding wrist straps to avoid ESD damage to the module.

Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

To install a XENPAK transceiver in a 10GBASE Ethernet module, follow these steps:

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

Note If you are unsure about the correct way to attach an ESD grounding strap, refer to the "Attaching Your ESD Grounding Strap" section on page C-1 for instructions.

Step 2 Loosen and remove the two M3 Phillips pan-head screws that secure the port cover to the supervisor engine faceplate and remove the port cover. Save the port cover and the two screws for future use.

Step 3 Remove the XENPAK transceiver from its protective packaging. If this is an optical XENPAK, do not remove optical bore plugs from the XENPAK at this time. Check the label on the XENPAK transceiver to verify that it is the correct model for your network.

Step 4 Align the XENPAK transceiver with the opening in the supervisor engine faceplate, and slide the XENPAK transceiver into the opening until the XENPAK transceiver faceplate is in contact with the supervisor engine faceplate. (See Figure 3-17.) This step ensures that the XENPAK transceiver is fully seated in the socket.

Step 5 Tighten the two captive installation screws to secure the XENPAK transceiver in the socket. Avoid cross-threading and do not overtighten the captive installation screws.

Step 6 You are now ready to attach the network interface cables to the XENPAK transceiver.

Note See "Attaching the Network Interface Cables" section for instructions.

Figure 3-17 Installing a XENPAK Transceiver

Installing the 10-Gigabit Ethernet X2 Transceivers

This section provides a procedure on how to install 10GBASE-X X2 transceivers in the uplink ports on the Supervisor Engine 720-10GE. There are different types of X2 transceivers but all share the same form factor. For additional information on X2 transceivers, including recommended cabling distances, see the "10-GB X2 Transceivers" section on page A-10.

The 10-Gigabit Ethernet X2 transceiver module that you receive can have either a spring-loaded latch sleeve or a latch sleeve that is not spring loaded. Both X2 transceiver types are functionally identical.

Note This installation procedure applies to both the spring-loaded and non-spring-loaded X2 transceivers.

Caution The X2 transceiver is a static-sensitive device. Always use an ESD wrist strap or similar individual grounding device when handling X2 transceivers or coming into contact with the supervisor engine.

To install an X2 transceiver, follow these steps:

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

Note If you are unsure about the correct way to attach an ESD grounding strap, see the "Attaching Your ESD Grounding Strap" section on page C-1 for instructions.

Step 2 Using a small flat-blade screwdriver, carefully pry the X2 transceiver port cover off of the supervisor engine uplink port faceplate.

Use the two arrows on the port cover as guides for inserting the screwdriver blade. Save the port cover for future use.

Step 3 Remove the X2 transceiver from its protective packaging.

Note Do not remove the optical bore dust plugs until directed to do so later in the procedure.

Step 4 Check the label on the X2 transceiver body to verify that you have the correct model for your network.

Step 5 To install the X2 transceiver, do the following:

b. Insert the X2 transceiver into the transceiver socket on the supervisor engine front panel. (See Figure 3-18, top view.) Continue sliding the X2 transceiver into the socket until the X2 transceiver EMI gasket is flush against the supervisor engine faceplate. The X2 transceiver connector is now mated to the socket connector.

c. Verify that the X2 transceiver latches are fully engaged and secure by sliding the transceiver latching sleeve toward the supervisor engine faceplate. (See Figure 3-18, bottom view.)

Caution If the latches are not fully engaged, you may accidently disconnect the X2 transceiver.

Figure 3-18 Installing the 10-Gigabit Ethernet X2 Transceiver Module

Note 10-Gigabit Ethernet X2 transceivers are keyed to prevent incorrect insertion.

Step 6 If you are cabling an optical X2 transceiver, perform the following substeps. If you are cabling a CX4 X2 transceiver, go to Step 7.

Note Before removing the dust plugs and making any optical connections, observe the following guidelines:

•Always keep the protective dust plugs on the unplugged fiber-optic cable connectors and the transceiver optical bores until you are ready to make a connection.

•Always inspect and clean the SC connector end-faces just before making any connections. Refer to the following Tip for a pointer to a white paper that describes the fiber-optic inspection and cleaning process.

•Always grasp the SC connector housing to plug or unplug a fiber-optic cable.

a. Remove the dust plugs from the optical network interface cable SC connectors. Save the dust plugs for future use.

b. Inspect and clean the SC connector's fiber-optic end-faces. Refer to the Tip below for a pointer to a white paper that describes the fiber-optic inspection and cleaning process.

Tip For complete information on inspecting and cleaning fiber-optic connections, refer to the white paper document at this URL:

http://www.cisco.com/en/US/tech/tk482/tk607/technologies_white_paper09186a0080254eba.shtml

c. Remove the dust plugs from the X2 transceiver optical bores.

d. Immediately attach the network interface cable SC connectors to the X2 transceiver. (See Figure 3-19 for cabling an optical X2 transceiver.)

Figure 3-19 Cabling an Optical 10-Gigabit Ethernet X2 Transceiver

Step 7 Plug the InfiniBand cable connector into the CX4 X2 transceiver connector. (See Figure 3-20.) Make sure that the InfiniBand cable connector is aligned with the X2 transceiver.

Note The Cisco X2-10GB-CX4 transceiver supports link lengths of up to 49.2 feet (15 m) using CX4 cable. Cisco offers four CX4 cables:

•CAB-INF-28G-1= (1 meter cable)

•CAB-INF-28G-5= (5 meter cable)

•CAB-INF-28G-10= (10  meter cable)

•CAB-INF-28G-15= (15 meter cable)

Figure 3-20 Cabling a CX4 (Copper) 10-Gigabit Ethernet X2 Transceiver Module

Step 8 Carefully route the InfiniBand network cable through the cable management brackets on your system. Figure 3-21 shows how the InfiniBand cable should be routed through either a horizontal cable management bracket or a vertical cable management bracket to provide adequate strain relief and support to prevent connector sag or skew.

Note Make sure that you route the InfiniBand cable through cable management brackets to provide adequate strain relief and cable support when cabling CX4 X2 transceivers. The InfiniBand cable is heavy. Without proper support, the InfiniBand cable can cause the cable connector to sag or skew. Misalignment between the cable connector and the transceiver connector can cause intermittent connections between the cable connector pins and the CX4 X2 transceiver pins.

Figure 3-21 InfiniBand Cable Support

Attaching the Network Interface Cables

This section describes how to attach network interface cables (optical and copper) to the supervisor engine uplink ports and contains the following topics:

•Attaching Optical Network Interface Cables

•Mode-Conditioning Patch Cord

•Connecting Transceivers to a Copper Network

Attaching Optical Network Interface Cables

Before you remove the dust plugs from the connector optical bores and make any connections, observe the following guidelines:

•Always keep the protective dust plugs on the unplugged fiber-optic cable connectors and the transceiver optical bores until you are ready to make a connection.

Caution Do not remove the plugs from the transceiver optical bores or the fiber-optic cable until you are ready to connect the cable. The plugs protect the transceiver optical bores and cable from contamination.

•Always inspect and clean the SC or the LC connector end-faces just before making any connections. Refer to the Tip on inspecting and cleaning fiber-optic connections for the location of a document that describes the fiber-optic inspection and cleaning process.

•Always grasp the SC or the LC connector housing instead of the fiber-optic cable to plug or unplug the fiber-optic cable.

To install the optical interface cables, follow these steps:

Step 1 Remove the dust plugs from the network interface cable optical connectors. Save the dust plugs for future use.

Step 2 Immediately inspect and clean the optical connector's fiber-optic end faces.

Step 3 Remove the dust plugs from the transceiver optical bores.

Note If you are using 1000BASE-LX, 10GBASE-LX4, or 10GBASE-LRM transceivers with FDDI-grade, OM1, or OM2 fiber-optic cable you need to install a mode-conditioning patch cord at each end of the link. If you are using OM3 fiber-optic cable, you do not need to install a mode-conditioning patch cord. Three mode-conditioning patch cords are available from Cisco: CAB-GELX-625=, CAB-MCP50-SC=, and CAB-MCP-LC=. For more information on mode-conditioning patch cords and their usage, see the "Mode-Conditioning Patch Cords" section on page A-26.

Note The read-only WDM GBIC (WDM-GBIC-REC=) has only one optical bore (receive).

Step 4 Immediately attach the network interface cable optical connector to the transceiver.

When an unconditioned laser source designed for operation on single-mode optical fiber is directly coupled to a multimode optical fiber cable, an effect known as differential mode delay (DMD) might result in a degradation of the modal bandwidth of the optical fiber cable.

This degradation results in a decrease in the link span (the distance between a transmitter and a receiver) that can be supported reliably. The effect of DMD can be overcome by conditioning the launch characteristics of a laser source. A practical means of performing this conditioning is to use a device called a mode-conditioning patch cord.

A mode-conditioning patch cord is an optical fiber cable assembly that consists of a pair of optical fibers terminated with connector hardware. Specifically, the mode-conditioning patch cord is composed of a single-mode optical fiber permanently coupled off-center (see Offset in Figure 3-22 and Figure 3-23) to a graded-index multimode optical fiber. Figure 3-22 and Figure 3-23 show a diagram of the mode-conditioning patch cord assembly.

The mode-conditioning patch cord assembly is composed of duplex optical fibers, including a single-mode-to-multimode offset launch fiber connected to the transmitter, and a second conventional graded-index multimode optical fiber connected to the receiver. The use of a plug-to-plug patch cord maximizes the power budget of multimode 1000BASE-LX/LH links.

Note The mode-conditioning patch cord is required to comply with IEEE standards. The IEEE found that link distances could not be met with certain types of fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center, which is accomplished by using the mode-conditioning patch cord. At the output end of the patch cord, the GBIC-LX/LH is compliant with the IEEE 802.3z standard for 1000BASE-LX.

Connecting Transceivers to a Copper Network

Caution To comply with GR-1089 intrabuilding lightning immunity requirements, you must use grounded, shielded, twisted-pair Category 5 cabling.

To connect transceivers to a copper network, follow these steps:

Step 1 Insert the network cable RJ-45 connector into the RJ-45 connector on the transceiver.

Note When connecting to a 1000BASE-T-compatible switch or repeater, use four-twisted-pair, crossover Category 5 cabling.

Step 2 Insert the other end of the network cable into an RJ-45 connector on a 1000BASE-T-compatible target device.
