Dual-Port Fast Ethernet PIM

The Dual-Port 10/100-Mbps Fast Ethernet PIM (Figure 34 on page 60) has two physical Fast Ethernet ports.

Figure 34: Fast Ethernet PIM

The Dual-Port Fast Ethernet PIM provides the following key features:

■Onboard network processor

■Full-duplex and half-duplex modes

■Media access control (MAC) address filtering

■Autonegotiation through medium-dependent interface (MDI) and MDI crossover (MDI–X) support

For pinouts of cable connectors for Fast Ethernet PIMs, see “Fast Ethernet RJ-45

Connector Pinout” on page 233.

To install or remove a PIM, see “Replacing a PIM” on page 172.

Fast Ethernet LEDs indicate link status, port speed, and activity. Table 29 on page 61 describes the meaning of the LEDs.
