About Two-Port Gigabit Ethernet Interface Modules

The Catalyst 8540 switch router supports a two-port Gigabit Ethernet interface module that has 1000-Mbps of Layer 2 or Layer 3 fiber-optic connections. It provides two Gigabit Ethernet ports that have GBIC modular transceivers and SC-type fiber connectors. The two-port Gigabit Ethernet interface module is available with 16 KB or 64 KB of memory. Routing tables use this memory.

Interface Ports Supported

Table 22-1 identifies the maximum number of two-port Gigabit Ethernet interface ports supported in each system.

Figure 22-1 shows a two-port Gigabit Ethernet interface module.

Connections supported

The two-port Gigabit Ethernet interface module with GBIC technology for flexible port interface types provide the following connections:

• Short wavelength multimode fiber
  
  
• Long wavelength multimode fiber
  
  
• Single-mode fiber
  
  
• Gigabit Ethernet over UTP5
  
  

Cabling Two-Port Gigabit Ethernet Interface Modules

This section describes supported cabling configurations for the two-port interface module. It provides two Gigabit Ethernet ports that have Gigabit Interface Converter (GBIC) modular transceivers and SC-type fiber connectors.

Note   See "Connectors and Connector Pinouts," for cabling requirements.

Two-Port Gigabit Ethernet Interface Module Connectors

To connect the two-port Gigabit Ethernet interface module to an external device, use an SC-type connector for multimode and single-mode fiber-optic traffic. (See Figure 22-2.)

Figure 22-2: Two-Port Gigabit Ethernet Network Connections and LEDs

Note   See "Connectors and Connector Pinouts," for SC-type connector information. Figure 2-12 shows a GBIC.

Two-Port Gigabit Ethernet Interface Module LEDs

The LEDs provide status information for the network connection. Figure 22-2 shows the LEDs for the two-port Gigabit Ethernet interface module. Table 22-2 describes the LEDs.
