16-Port 10/100BASE-T Fast Ethernet Interface Modules

This chapter describes the 16-port 10/100BASE-T Fast Ethernet interface module supported by the following systems:

  • Catalyst 8540 MSR

  • Catalyst 8540 CSR

This chapter includes the following sections:

About 16-Port 10/100BASE-T Interface Modules

The Catalyst 8540 supports a 16-port 10/100BASE-T interface module. The 16-port 10/100BASE-T interface module is available with either 16 KB or 64 KB of memory, which is used by the routing tables.

Interface Ports Supported

Table 18-1 identifies the maximum number of interface ports supported in each system.

Connections Supported

The 16-port 10/100BASE-T interface module provides connections for category 5 UTP using RJ-45 connectors.

Cabling 16-Port 10/100BASE-T Interface Modules

This section describes supported cabling configurations for the 16-port 10/100BASE-T interface module that provides 10-Mbps or 100-Mbps Layer 2 or Layer 3 unshielded twisted-pair (UTP) connections. It provides full-duplex or half-duplex connections and Fast EtherChannel operation.


Note   "Connectors and Connector Pinouts," lists cabling requirements.

16-Port 10/100BASE-T Interface Module Connectors

To connect the 16-port 10/100BASE-T interface module to an external device, use RJ-45 connectors. (See Figure 18-2.)
