Description

The single-port 1000BASE-T GBIC (model WS-G5482 or WS-G5483) has these features:

Management through the Cisco IOS command-line interface (CLI), Catalyst software CLI, or the web-based Cluster Management Suite (CMS)

Full-duplex connectivity between two devices

The GBIC supports automatic medium-dependent interface crossover (Auto-MDIX). The GBIC automatically detects the required cable connection type (straight through or crossover) and configures the connection appropriately.


Caution The 1000BASE-T GBIC does not support half duplex. Configuring the GBIC port for half duplex causes collisions.

Caution In compliance with FCC Class A, you can install up to 12 WS-G5483 GBICs in a Catalyst 6000 family switch chassis.

Note The Catalyst 2950, Catalyst 4000 family, and Catalyst 6000 family switches support only the WS-G5483 GBIC.


Figure 1 shows the 1000BASE-T GBIC.

Figure 1 1000BASE-T GBIC

Supported Switches

For a list of the switches and switching modules that support the GBIC, refer to the online 1000BASE-T GBIC Switch Compatibility Matrix. The switches detect and enable the GBIC only when they are running the minimum software releases in the list.

For example, if your Catalyst 2900 XL or 3500 XL switch is running Cisco IOS Release 12.0(5)XW or later, it detects and enables the WS-G5482 GBIC. You can manage this GBIC by using the CLI or the Cluster Management Suite (CMS). If the switch is running a Cisco IOS release earlier than Cisco IOS Release 12.0(5)XW, it does not detect and enable this GBIC. You must upgrade your software to Cisco IOS Release 12.0(5)XW or later. To upgrade to Cisco IOS Release 12.0(5)XW or later, refer to the release notes for the upgrade procedures. After you upgrade the software, the switch detects and enables the GBIC.

If your Catalyst 2900 XL or 3500 XL switch is running Cisco IOS Release 12.0(5)WC3 or later, it also detects and enables the WS-G5483 GBIC. You can manage this GBIC by using the CLI or the CMS. If the switch is running a Cisco IOS release earlier than Cisco IOS Release 12.0(5)WC3, it does not detect and enable this GBIC. You must upgrade your software to Cisco IOS Release 12.0(5)WC3 or later. To upgrade to Cisco IOS Release 12.0(5)WC3 or later, refer to the release notes for the upgrade procedures. After you upgrade the software, the switch detects and enables the GBIC.

Connecting to 1000BASE-T Ports


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, router, switch, or repeater, use straight-through or crossover, four twisted-pair, Category 5 cabling for the GBIC port.

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.

Obtaining Technical Assistance

For all customers, partners, resellers, and distributors who hold valid Cisco service contracts, Cisco Technical Support provides 24-hour-a-day, award-winning technical assistance. The Cisco Technical Support Website on Cisco.com features extensive online support resources. In addition, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not hold a valid Cisco service contract, contact your reseller.

Cisco Technical Support Website

The Cisco Technical Support Website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, 365 days a year at this URL:

http://www.cisco.com/techsupport

Access to all tools on the Cisco Technical Support Website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

http://tools.cisco.com/RPF/register/register.do

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool automatically provides recommended solutions. If your issue is not resolved using the recommended resources, your service request will be assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553 2447

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
