Software release

  • 1-port, 4-port: Junos OS Release 5.2 and later
  • 2-port: Junos OS Release 5.3 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

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

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
