Juniper Networks J2350 manual Port Fast Ethernet ePIM

JUNOS Software with Enhanced Services Hardware Guide

4-Port Fast Ethernet ePIM

You can install 4-Port Fast Ethernet ePIMs in any of the high-speed slots, as follows:

■J4350—Install up to two 4-Port Fast Ethernet ePIMs in slots 3 and 6.

■J6350—Install up to four 4-Port Fast Ethernet ePIMs in slots 2, 3, 5, and 6.

NOTE: For 4-port Fast Ethernet ePIMs, if you apply a CoS scheduler map on outgoing (egress) traffic, the router does not divide the bandwidth appropriately among the CoS queues. As a workaround, configure enforced CoS shaping on the ports.

The 4-Port 10/100-Mbps Fast Ethernet ePIM, shown in Figure 35 on page 54, has four physical Fast Ethernet ports.

The 4-Port Fast Ethernet ePIM provides the following key features:

■Full-duplex and half-duplex modes.

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

For pinouts of cable connectors for Fast Ethernet ePIMs, see “Fast Ethernet RJ-45 Connector Pinout” on page 189.

NOTE: 4-port Fast Ethernet ePIMs support a maximum frame size of 1514 bytes.

Jumbo frames are not supported.

For information about installing and removing a PIM, see “Replacing a

PIM” on page 120.

Fast Ethernet LEDs indicate link status and activity. Table 30 on page 55 describes the meaning of the LEDs.
