Software release
- 4-port: JUNOS 7.6R3 and later (Type 1)
- 8-port: JUNOS 7.6R2 and later (Type 2) M320 routers support no more than three 8-port Ethernet IQ2 PICs in an FPC2. Table 19 describes which PICs can be installed in the fourth slot of the FPC2.
- 8-port: JUNOS 8.2 and later (Type 3)
Description
- Four or eight Gigabit Ethernet ports
- Power requirement:
- 4-port: 0.65 A @ 48 V (31 W)
- 8-port (Type 2): 0.89 A @ 48 V (42.5 W)
- 8-port (Type 3): 1.25 A @48 V (60 W)
Hardware features
- High-performance throughput on each port:
- 4-port with SFP: speeds up to 1 Gbps
- 8-port with SFP: speeds up to 4 Gbps
- Full-duplex mode
- Large maximum transmission units (MTUs) of up to 9192 bytes
Software features
- Intelligent handling of oversubscribed traffic for the Type 1 and Type 2 PICs
- Optical diagnostics and related alarms
- Quality of service (QoS) per channel: weighted round-robin (WRR), random early detection (RED), weighted random early detection (WRED)
- Virtual Router Redundancy Protocol (VRRP) support
- Hierarchical shaping
- 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
- Flexible Ethernet encapsulation
- MAC learning, policing, accounting, and filtering
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 Instructions.Do not install SONET/SDH SFPs in the Gigabit Ethernet port. The port will not recognize the SFP.
- Fiber-optic small form-factor pluggable transceivers (SFPs):
- Copper 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
LEDs OK or Status LED, one tricolor:
- Off—PIC is offline and it is safe to remove it from the router.
- Green—PIC is operating normally.
- Amber—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.
