Figure 0: Left: 1-Port Gigabit Ethernet IQ; Right: 2-Port Gigabit Ethernet IQ

Software release
  • 1-port: JUNOS 6.0 and later
  • 2-port: JUNOS 6.1 and later
Description
  • One or two Gigabit Ethernet ports
  • Power requirements: 0.46 A/48 V @ 22 W
  • Intelligent queuing (IQ) PICs support fine-grained queuing per logical interface.
  • Optical interface support—see Table 9

Note: On the M5, M10, M20, M40, and M160 routers, this PIC requires an Enhanced FPC. See the hardware guide for your router for more information.

Hardware features
  • High-performance throughput on all ports at speeds up to 1 Gbps
  • Full-duplex mode
  • Large MTUs of up to 9192 bytes
Software features
  • Quality of Service (QoS) per channel: Weighted Round Robin (WRR), Random Early Drop (RED), Weighted Random Early Drop (WRED)
  • Virtual Router Redundancy Protocol (VRRP) support
  • 802.1Q Virtual LANs (VLANs)
  • VLAN stacking and rewriting
  • MAC policing, accounts, and filters

Note: Extended support for graceful Routing Engine switchover (GRES) has been added for this PIC. To configure GRES, you must be running JUNOS release 7.3 or later.

Cables and connectors
  • You can use 1000Base-T, 1000Base-SX, 1000Base-LX, and 1000Base-LH SFPs to install different optical interfaces on the PIC. PICs with multiple ports can use any combination of SFPs.
  • SX, LX, and LH small form-factor pluggable transceivers (SFPs):
    • Duplex LC/PC connector (Rx and Tx)
  • 1000Base-T SFPs:
    • Connector: Four-pair, category 5 shielded twisted-pair connectivity through an RJ-45 connector
    • Pinout: MDI crossover
    • Length: 328-ft/100-m

Note: Do not install SONET/SDH OC48c/STM16 SFPs in the Gigabit Ethernet port. The port will not recognize the SFP.

  • Duplex LC/PC connector (Rx and Tx)

Note: PICs with multiple ports can use any combination of SFPs. For information about installing and removing SFPs, see the M160 Internet Router Hardware Guide.

LEDs Status LEDs, one tricolor:
  • Off—Not enabled
  • Green—Online with no alarms or failures
  • Amber—Online with alarms for remote failures
  • Red—Active with a local alarm; router has detected a failure

Note: The green status LED is lit on the 2-port Gigabit Ethernet IQ PIC when at least one port is online.


Port LEDs, one per port:
  • Off—Port is down
  • Green—Link is established
