Software release

• 1-port: Junos OS Release 6.3 and later
• 2-port: Junos OS Release 6.4 and later
• 4-port: Junos OS Release 7.0 and later

Description

• One, two, or four Gigabit Ethernet ports
• Power requirement:
  • 1-port: 0.15 A @ 48 V (7.3 W)
  • 2-port: 0.25 A @ 48 V (11.9 W)
  • 4-port: 0.50 A @ 48 V (23.8 W)
• Supports large Ethernet frame sizes for more efficient throughput across the intra-POP network

Hardware features

• High-performance throughput on each port 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
• 960 destination MAC filters per port
• Optical diagnostics and related alarms on the 2-port and 4-port PICs (Junos OS Release 8.2 and later)
• Flexible Ethernet encapsulation
• Multiple tag protocol identifiers (TPID) support
• Source MAC learning
• MAC accounting and policing—Dynamic local address learning of source MAC addresses

Cables and connectors

• You can install any transceiver supported by the PIC.
• Fiber-optic SFP transceivers:
  • Duplex LC/PC connector (Rx and Tx)
  • Small form-factor pluggable (SFP) transceivers:
    • 1000Base-LH (model number: SFP-1GE-LH)
    • 1000Base-LX (model number: SFP-1GE-LX)
    • 1000Base-SX (model number: SFP-1GE-SX)

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

• Copper transceivers:
  • Connector: Four-pair, Category 5 shielded twisted-pair connectivity through an RJ-45 connector
  • 1000Base-T (model number: SFP-1-GE-T)

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

Note: Do not install Gigabit Ethernet SFPs in the SONET/SDH port. The port will not recognize the SFP.

LEDs

Status LED, one bicolor:

• Off—PIC is 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
