To continue your GEIP+ installation, you must attach the cables to the Gigabit Interface Converter (GBIC) on your port adapter.
Your GEIP+ shipped with a GBIC installed, depending on the GBIC model you ordered (1000BaseSX, 1000BaseLX, or Long Haul).
 |
Note If your GEIP+ arrived without the GBIC installed and you need to install it now, or you need to change
your GBIC for another reason, use the procedures in the
"Replacing a GBIC in the GEIP+" section on
page 4-4. If your GBIC is installed, use the procedures in the "Connecting Cables to the GEIP+" section that follows. |
The two cabling options for the GEIP+ are discussed in the following sections:
Use this cabling option for the following connections:
(For specific information about multimode and single-mode optical fiber cables, refer to Table 1-4 and the "Optical Fiber Cables" section.)
Use this cabling option for a GEIP+ with a GBIC-LX or a GBIC-LH when you expect transmission distances to be greater than 984.25 feet (300 meters) over 50/125-micron or 62.5/125-micron multimode fiber. (For specific information about the mode-conditioning patch cord, see the "Mode-Conditioning Patch Cord with a Multimode GBIC-LX and GBIC-LH" section.)
 |
Caution To prevent transmission problems, do not use the mode-conditioning patch cord with 9/125-micron or 10/125-micron single-mode optical fiber under any circumstances. |
This section provides the cable-attachment procedure for the following connections:
|
Caution If you plan to use a GBIC-LX or a GBIC-LH in your GEIP+ at distances greater than 984.25 feet (300 meters) over 50/125-micron or 62.5/125-micron multimode fiber, to prevent data transmission problems you must use the mode-conditioning patch cord. Do not use the procedure in this section. Instead, proceed to the "Attaching a Mode-Conditioning Patch Cord to a GBIC-LX or GBIC-LH" section. |
|
Note Optical fiber cables are not available from Cisco Systems; they are available from outside commercial cable vendors. (For information on the proper cables to use, see Table 1-4 and the "Optical Fiber Cables" section.) |
Use the following procedure to attach multimode or single-mode optical fiber cables to your GBIC:
|
Caution To prevent transmission problems, ensure that you connect the TX and RX ports on one end of the optical fiber cable to the RX and TX ports (respectively) on the other end. In other words, connect TX to RX and RX to TX. |
 |
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. |
|
Warning Class 1 laser product. |
Step 2 Attach the network ends of your optical fiber cables to the 1000BaseX equipment in your cable plant.
This completes the procedure for attaching optical fiber cable to your GBIC.
This section describes the procedure for attaching a mode-conditioning patch cord to your GBIC-LX or GBIC-LH when you expect transmission distances to be greater than 984.25 feet (300 meters) over 50/125-micron or 62.5/125-micron multimode fiber. The mode-conditioning patch cord is available from Cisco Systems as Product Number CAB-GELX-625=. (For specific information about the mode-conditioning patch cord, see the "Mode-Conditioning Patch Cord with a Multimode GBIC-LX and GBIC-LH" section.)
|
Note If you use a GBIC-LX or GBIC-LH with single-mode optical fiber connections, you do not need to use the mode-conditioning patch cord; therefore, proceed to the "Attaching Multimode and Single-Mode Optical Fiber Cables to a GBIC" section. |
The network end of the GBIC has a duplex SC-type receptacle. You must attach the mode-conditioning patch cord to the SC-type receptacle on your GBIC (the GE interface).
Use the following procedure to attach the mode-conditioning patch cord to your GBIC:
|
Caution To prevent transmission problems, ensure that you connect the TX and RX ports on one end of the patch cord to the RX and TX ports (respectively) on the other end. In other words, connect TX to RX and RX to TX. |
|
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. |
|
Warning Class 1 laser product. |
Step 2 Attach the network ends of your mode-conditioning patch cord to the appropriate 1000BaseX equipment in your building cable plant. (See Figure 4-2.)
This completes the procedure for attaching a mode-conditioning patch cord to your GBIC.
Your GEIP+ shipped with a GBIC installed, depending on the GBIC model you ordered (1000BaseSX, 1000BaseLX, or Long Haul).
|
Note If your GEIP+ arrived without the GBIC installed and you need to install it now, or you need to change your GBIC for another reason, use the procedures in this section; otherwise, you do not need to use these procedures. |
|
Caution To prevent system problems, do not use GBICs from third-party vendors. Use only the GBIC that shipped with your GEIP+. |
|
Note If your GBIC is already properly installed, proceed to the "Attaching Multimode and Single-Mode Optical Fiber Cables to a GBIC" section; otherwise, continue with the following procedure. |
|
Caution To prevent problems associated with data transmission, you must attach this device only to devices compliant with IEEE 802.3x specifications. |
|
Note You can install and remove GBICs with power on to the system; however, we strongly recommend that you do not install or remove the GBIC with optical fiber cables attached to it. Disconnect all cables before removing or installing a GBIC. |
Use the following procedure to remove a GBIC from the GEIP+:
Step 2 Attach an ESD-preventive wrist strap between you and an unpainted chassis surface.
Step 3 Locate the tabs on either side of the exposed portion of the GBIC and squeeze them with your thumb and forefinger as you gently pull the GBIC out of the GBIC slot. (See arrows in Figure 4-3.)
Use the following procedure to insert a GBIC into the GEIP+:
Step 2 Locate the alignment groove on the GBIC. (See the enlargement in Figure 4-3.) Position the GBIC so that this groove is in the position shown in the enlargement, to ensure that the 20-pin plug on the GBIC is in the correct position.
|
Caution To prevent damage to the GBIC plug and receptacle before you insert the GBIC into the GBIC slot on the GEIP+, ensure that the plug is in the orientation shown in Figure 4-4. |
Step 3 Squeeze the tabs on each side of the GBIC using your thumb and forefinger, and insert the GBIC into the GBIC slot on the GEIP+. (See Figure 4-3.)
Step 4 Using moderate force, ensure that the GBIC is fully inserted into the 20-pin receptacle at the rear of the GBIC slot. The tabs on either side of the GBIC snap into place when you have completely and properly inserted the GBIC.
Step 5 Reattach the SC-type optical fiber cable or the mode-conditioning patch cord to the GBIC. (Use the appropriate procedure in the "Connecting Cables to the GEIP+" section.)
This completes the procedures for replacing the GBIC in your GEIP+.
