1-Port Gigabit Ethernet ePIMs

The 1-port Gigabit Ethernet ePIM is supported on J4350 and J6350 Services Routers and is available in two versions, one with copper connector (see Figure 26), the other with small form-factor pluggable (SFP) transceivers (see Figure 27).

Features. The Gigabit Ethernet ePIM provides the following key features:

• Autonegotiation through medium-dependent interface (MDI) and MDI crossover (MDI-X) support.
• Link speeds for the Copper Gigabit Ethernet ePIM are configurable to 10, 100, or 1000 Mbps, and transmission mode is configurable to half or full duplex. The SFP Gigabit Ethernet ePIM cannot be manually configured—it is set at 1000 Mbps and full duplex.
• The SFP Gigabit Ethernet ePIM uses SFPs to allow different connectors to be used on the ePIM ports. The ePIM supports 1000Base-SX, 1000Base-LX, and 1000Base-T copper SFPs. It does not support 1000Base-LH SFPs.

  1000Base-SX and 1000Base-LX SFP transceivers have the following characteristics:

  • Duplex LC/PC connector (Rx and Tx).
  • Optical interface support—See Table 23.

• Copper Gigabit Ethernet ePIM and 1000Base-T SFP transceivers have the following characteristics:
  • Connector: Four-pair, category 5 unshielded twisted-pair cable through an RJ-45 connector
  • Pinout: MDI crossover
  • Maximum distance: 100 m (328 ft)

For pinouts of cable connectors for Copper Gigabit Ethernet ePIMs, see Gigabit Ethernet ePIM RJ-45 Connector Pinout.

Limitations. The Gigabit Ethernet ePIM has the following limitations:

• Gigabit Ethernet ePIMs do not support SNMP.
• Configure Gigabit Ethernet ePIM interfaces up to a maximum MTU size of 9018 bytes.

Installation. You can install Gigabit Ethernet ePIMs in any high-speed slot as follows:

• J4350—Install up to two Gigabit Ethernet ePIMs in slots 3 and 6.
• J6350—Install up to four Gigabit Ethernet ePIMs in slots 2, 3, 5, and 6.

Note: High-speed slots are labeled with an E on the front-panel slot number diagram.

Interface LEDs. The LINK and TX/RX LEDs indicate link status and activity. Table 22 describes the meaning of the LEDs.

For alarms, see the configuring and monitoring alarms information in the JUNOS Software Administration Guide.

Optical Interface Support. Table 23 describes the optical interface support on the SFP Gigabit Ethernet ePIM over single-mode fiber-optic (SMF) and multimode fiber-optic (MMF) cables.
