- One or two Gigabit Ethernet ports
- Power requirement: 0.46 A @ 48 V (22 W)
- Fine-grained queuing per logical interface
- Optical interface support—See Table 17
- High-performance throughput on each port at speeds up
to 1 Gbps
- Full-duplex mode
- Large MTUs of up to 9192 bytes
- Optical diagnostics and related alarms
- Quality of service (QoS) per channel: weighted round-robin
(WRR), random early detection (RED), weighted random early detection
- Virtual Router Redundancy Protocol (VRRP) support
- 802.1q virtual LANs (VLANs)
- VLAN stacking and rewriting
- Flexible Ethernet encapsulation
- MAC policing, accounts, and filters
- JUNOS release 7.0 or later is required to configure graceful
Routing Engine switchover (GRES).
Cables and connectors
- You can install any transceiver supported by the PIC.
For information about installing and removing transceivers, see the PIC and Transceiver Installation
- Fiber-optic SFP transceivers:
- Duplex LC/PC connector (Rx and Tx)
- Optical interface support—see Table 17
- 1000Base-T SFP transceivers:
- Connector: Four-pair, Category 5 shielded twisted-pair
connectivity through an RJ-45 connector
- Pinout: MDI crossover
- Length: 328 ft/100 m
Do not install SONET/SDH OC48c/STM16 SFPs in
the Gigabit Ethernet port. The port will not recognize the SFP.
Status LED, 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
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.
