Juniper Networks J2350 manual Optical Interface Support for SFP Gigabit Ethernet ePIM

JUNOS Software with Enhanced Services Hardware Guide

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.

To install or remove a PIM, see “Replacing a PIM” on page 120.

Interface LEDs. The LINK and TX/RX LEDs indicate link status and activity.

Table 23 on page 46 describes the meaning of the LEDs.

Table 23: Gigabit Ethernet Port LEDs

Function	Color	State	Description
LINK	Green	On steadily	Port is online.
	Unlit	Off	Port is offline.
TX/RX	Green	Blinking	Port is transmitting or receiving traffic.
	Unlit	Off	Port might be online, but it is not
			receiving traffic.

For alarms, see the configuring and monitoring alarms information in the JUNOS

Software Administration Guide.

Optical Interface Support. Table 24 on page 46 describes the optical interface support on the SFP Gigabit Ethernet ePIM over single-mode fiber-optic (SMF) and multimode fiber-optic (MMF) cables.
