Software release

• 2-port and 4-port: Junos OS Release 5.3 and later

Description

• Two or four Gigabit Ethernet ports
• Power requirements:
  • 2-port: 0.35 A @ 48 V (17 W)
  • 4-port: 0.40 A @ 48 V (19.2 W)
• Supports large Ethernet frame sizes for more efficient throughput across the intra-POP network

Hardware features

• High-performance throughput on all ports at speeds up to 1 Gbps
• Autonegotiation between Gigabit Ethernet circuit partners
• Full-duplex mode
• Maximum transmission units (MTUs) of up to 9192 bytes

Note: If you use a 4-port Gigabit Ethernet PIC on a Juniper Networks M160 router, the MTU will decrease to 4500 bytes.

Software features

• Virtual Router Redundancy Protocol (VRRP) support
• 802.1Q virtual LANs (VLANs) support
• 64 source MAC address filters per port
• 960 destination MAC filters per port

Cables and connectors

• Duplex SC connector (TX and RX)
• Fiber-optic SFP transceivers:
  • 1000Base-LH (model number: SFP-1GE-LH)
  • 1000Base-LX (model number: SFP-1GE-LX)
  • 1000Base-SX (model number: SFP-1GE-SX)
  • 1000Base-T (model number: SFP-1-GE-T)

  Optical interface specifications—see Ethernet 10BASE, 100BASE, and 1000BASE Copper and Optical Specifications

LEDs

Status LEDs, one bicolor:

• Off—PIC not enabled
• Green—PIC is operating normally
• Red—PIC has an error or failure

Port LEDs, one pair per port:

• Link—If green, the port is online; if there is no light, the port is down
• Activity—If flashing green, the port is receiving data; if there is no light, the port might be on, but is not receiving data
