Gigabit Ethernet PICs

Software release

1-port: JUNOS 4.0 and later 2-port: JUNOS 4.1 and later 4-port: JUNOS 5.0 and later

Description	One, two, or four Gigabit Ethernet ports Power requirements: 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 Optical interface support—see Table 4
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/PC connector (TX and RX)
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
