Two-Port Enhanced Gigabit Ethernet Interface Modules

This chapter describes the two-port Enhanced Gigabit Ethernet interface module supported by the following systems:

  • Catalyst 8540 MSR

  • Catalyst 8540 CSR

About Two-Port Enhanced Gigabit Ethernet Interface Modules

The Catalyst 8540 supports a two-port enhanced Gigabit Ethernet interface module. It consists of two one-port Gigabit Ethernet port adapters attached to a carrier module. The port adapters are not hot swappable, but the complete interface module is hot swappable. The interface module is full-duplex, supports Fast EtherChannel operation, and provides built-in ACL functionality. It is available with 16 KB, 64 KB, or 256 KB of memory.


Note   The port adapters within the two-port interface modules must have matching routing table memory. That is, if the ATM OC-12c port adapter has 64 KB of routing table memory, the Gigabit Ethernet port adapter must have 64 KB of routing table memory for the interface module to function properly.

Interface Ports Supported

Table 24-1 identifies the maximum number of two-port enhanced Gigabit Ethernet interface ports supported in each system.

Connections supported

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

  • Short wavelength multimode fiber

  • Long wavelength multimode fiber

  • Single-mode fiber

  • Gigabit Ethernet over UTP

Cabling Two-Port Enhanced Gigabit Ethernet Interface Modules

This section describes supported cabling configurations for the enhanced two-port interface module that provides 1000-Mbps multimode and single-mode fiber-optic connections. It provides two Gigabit Ethernet ports that have Gigabit Interface Converter (GBIC) modular transceivers and SC-type fiber connectors.

The port adapters have GBIC modular transceivers and SC-type fiber connectors.


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

Two-Port Enhanced Gigabit Ethernet Interface Module Connectors

To connect the two-port enhanced Gigabit Ethernet interface module to an external device, use an SC-type connector for multimode and single-mode fiber-optic traffic. (See Figure 24-2.)

LED State Description

Link

Green

A port is operational (a signal is detected).

Off

No signal is detected.

Full-Duplex

On

A port is operating in full-duplex mode. This is always the case for an operational Gigabit Ethernet port.

Rx (Receive)

Green

A port is receiving a packet. Green for approximately 50 ms.

Off

No signal is detected.

Op-Det

Green

An optical signal from another Gigabit Ethernet module is detected. It is steadily on when there is a Gigabit connection.

Off

No signal is detected.

Tx (Transmit)

Green

A port is transmitting a packet. Green for approximately 50 ms.

Off

No signal is detected.

Rx Sync

Green

A port is synchronized with the port from which it is receiving data.
