Gigabit Ethernet Enhanced IQ2 (IQ2E) PIC with SFP (M7i Router)

 

Software release

  • Junos OS Release 9.4 and later

Description

  • Four Gigabit Ethernet ports

  • Power requirement: 0.67 A @ 48 V (32 W)

Hardware features

  • High-performance throughput on each port: speeds up to 1 Gbps

  • Full-duplex mode

  • Large maximum transmission units (MTUs) of up to 9192 bytes

Software features

  • Intelligent handling of oversubscribed traffic

  • Optical diagnostics and related alarms

  • Quality of service (QoS) per channel: weighted round-robin (WRR), random early detection (RED), weighted random early detection (WRED)

  • Drop statistics reported per queue for each of four priority-based drop profiles

  • Four levels of strict priorities with priority propagation among scheduling levels

  • Virtual Router Redundancy Protocol (VRRP) support

  • Hierarchical shaping and hierarchical scheduler

  • Fine-grained queuing and shaping per logical interface at both ingress and egress

  • 802.1q virtual LANs (VLANs)

  • VLAN stacking and rewriting

  • Channels defined by two stacked VLAN tags

  • Multiple tag protocol identifiers (TPID) support

  • IP service for nonstandard TPID and stacked VLAN tags

  • 802.1p rewrite per channel

  • Flexible mapping of channels and scheduler resources at both ingress and egress

  • 16,000 schedulers (2,000 schedulers with 8 queues each or 4,000 schedulers with 4 queues each)

  • Scheduler resources dynamically allocated across ports

  • Flexible Ethernet encapsulation

  • MAC learning, policing, accounting, and filtering

Cables and connectors

  • You can install any transceiver supported by the PIC.

  • Fiber-optic small form-factor pluggable (SFP) transceivers:

    • Duplex LC/PC connector (Rx and Tx)

    • 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 the Hardware Compatibility Tool at https://apps.juniper.net/hct/

  • Copper SFP transceiver:

    • Connector: Four-pair, Category 5 shielded twisted-pair connectivity through an RJ-45 connector

    • 1000Base-T (model number: SFP-1GE-T)

    • Pinout: MDI crossover

    • Copper interface specifications—see the Hardware Compatibility Tool at https://apps.juniper.net/hct/

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

LEDs

OK LED, one tricolor:

  • Off—PIC is offline and it is safe to remove it from the router.

  • Green—PIC is operating normally.

  • Yellow—PIC is initializing.

  • Red—PIC has an error or failure.

APP LED, one bicolor:

  • Off—Monitoring application is not running.

  • Green—Monitoring application is running under acceptable load.

Port LEDs, one per port:

  • Off—Port is not enabled.

  • Green—Port is online with no alarms or failures.
