The port can be connected to a 1000BASE-T-compatible device, such as a high-speed workstation, server, hub, router, or other switch. When connecting the GBIC to a workstation, server, or router, use four twisted-pair, straight-through cabling. When connecting the GBIC to a hub or other switch, use four twisted-pair, crossover cabling. The cable length from the GBIC to an attached device cannot exceed 328 feet (100 meters).
For connector pinouts and cable specifications, see the "Connectors and Cables" section.
Follow these guidelines when handling a GBIC:
Gigabit Ethernet devices are shipped without the GBIC installed.
|
Caution Installing this product in or connecting this product to an unauthorized device might damage the device. Refer to the online 1000BASE-T GBIC Switch Compatibility Matrix posted with the GBIC documentation on Cisco.com for the list of products that support the GBIC. |
GBICs are hot-swappable and are designed to prevent incorrect insertion.
Follow these steps to insert the GBIC in a GBIC or module slot:
Step 1 Remove the GBIC from the protective packaging.
Step 2 Grip the two plastic tabs with your thumb and forefinger.
Step 3 Insert the GBIC in the GBIC or module slot, and slide the GBIC in the slot until you hear a click. The click means the GBIC is locked in the slot.
If the GBIC is not inserted securely (not locked in the slot), the switch might not recognize it or might display the wrong media type after you enter the show interface privileged EXEC command on the Cisco IOS CLI or the show port command on the Catalyst software CLI. If this happens, remove and reinsert the GBIC. See the "Troubleshooting" section for more information.
To connect a 1000BASE-T-compatible device to the GBIC, see the "Connecting to 1000BASE-T Ports" section.
To remove the GBIC from the GBIC slot, disconnect the cable from the RJ-45 connector on the GBIC. Release the GBIC from the slot by simultaneously squeezing the two plastic tabs, and pull out the GBIC.

Caution To prevent electrostatic-discharge (ESD) damage, follow your normal board and component handling procedures. |
|
Caution To comply with GR-1089 intrabuilding lightning immunity requirements, you must use grounded, shielded, twisted-pair, Category 5 cabling. |
Step 1 When connecting to a 1000BASE-T-compatible server, workstation, or router, use four twisted-pair, straight-through Category 5 cabling for the GBIC port. When connecting to a 1000BASE-T-compatible switch or repeater, use four twisted-pair, crossover Category 5 cabling.
Step 2 Insert the other cable connector in an RJ-45 connector on a 1000BASE-T-compatible target device.
Step 3 Observe the port status LED.
The LED turns green when the GBIC and the target device have an established link.
The LED turns amber while STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the 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 the "Troubleshooting" section for solutions to cabling problems.
Step 4 Reconfigure and reboot the target device if necessary.
|
Caution The 1000BASE-T GBIC does not support half duplex. Configuring the GBIC port for half duplex causes collisions. |
The GBIC only supports 1000-Mbps full-duplex connections. If the port configuration settings are changed, the switch does not detect and enable the GBIC. An error message appears in the CLI, the Catalyst software CLI, or the CMS.
The Catalyst 2900 XL, Catalyst 2950, Catalyst 3500 XL, Catalyst 3550, Catalyst 4000 family, and Catalyst 6000 family switches detect and enable the GBIC only when they are running the minimum software releases listed in Table 1.
These tables describe how to detect and solve problems that might arise when you are installing the GBIC. If you are installing the GBIC in a 1000BASE-X module for a Catalyst 2900 XL switch, see Table 5. If you are installing the GBIC in a Catalyst 2950, Catalyst 3500 XL, or Catalyst 3550 switch, see Table 6. For more information, refer to the documentation that came with your switch or module.
If you are installing the GBIC in a Catalyst 4000 family or Catalyst 6000 family switch, refer to the hardware documentation that came with your switch or module for troubleshooting information.
| Symptom | Possible Causes | Corrective Action |

The GBIC port uses a standard RJ-45 connector. Figure 8 shows the pinout.
When connecting the port to a 1000BASE-T-compatible device, such as a server, workstation, or router, you must use four twisted-pair, straight-through Category 5 cabling. Figure 9 shows the straight-through cable schematics.
When connecting the port to a 1000BASE-T-compatible device, such as a switch or repeater, you must use four twisted-pair, crossover Category 5 cabling. Figure 10 shows the crossover cable schematics.
|
Note Use a straight-through cable to connect two ports only when one port is designated with an X. Use a crossover cable to connect two ports when both ports are designated with an X or when both ports do not have an X. |

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco's installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco's written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
· Turn the television or radio antenna until the interference stops.
· Move the equipment to one side or the other of the television or radio.
· Move the equipment farther away from the television or radio.
· Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.
