Gigabit Ethernet PIC

Image g003164.gif

Software release
  • JUNOS 4.1 and later
Description
  • One Gigabit Ethernet port
  • Power requirements: 0.27 A/48 V @ 13.2 W
  • Supports large Ethernet frame sizes for more efficient throughput across the intra-POP network
  • Optical interface support—see Table 7
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/PC connector (RX and TX)
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
