Software release	Junos OS Release 6.2 and later Junos OS Release 8.4 and later supports the 2-port PIC and 4-port PIC on the Enhanced III FPC2.
Description	One, two, or four Gigabit Ethernet ports Power requirement: 1-port: 0.27 A @ 48 V (13.2 W) 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
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 fixed transceivers: 1000Base-LH 1000Base-LX 1000Base-SX 1000Base-T Optical interface specifications—see Gigabit Ethernet 1000BASE Optical Interface 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
