Figure 0: Gigabit Ethernet PICs with SFP: 1-Port, 2-Port, and 4-Port
Software release
- 1-port: JUNOS 6.3 and later
- 2-port: JUNOS 6.4 and later
- 4-port: JUNOS 7.0 and later
Description
- One, two, four, or ten Gigabit Ethernet ports
- Power requirements:
- 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
- 10–port: 0.62 A/48 V @ 29.9 W
- Supports large Ethernet frame sizes for more efficient throughput across the intra-POP network
- Optical interface support—see Table 8
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
- 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
- 64 source MAC filters per VLAN and 1024 source MAC filters per port
- 960 destination MAC filters per port
- MAC accounting and policing—Dynamic local address learning of source MAC addresses
Note: MAC accounting and policing is not supported in 10–port Gigabit Ethernet with SFP.
Cables and connectors
- You can use 1000Base-T, 1000Base-SX, 1000Base-LX, and 1000Base-LH SFPs. PICs with multiple ports can use any combination of SFPs.
- SX, LX, and LH 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.
- 10-port PIC:
- Duplex LC/PC connector (TX and RX)
Note: This PIC uses small form-factor pluggables (SFPs) that allow different optical interfaces to be used on the PIC. You can use SX, LX, and LH SFPs. For information about installing and removing SFPs, see the M160 Internet Router Hardware Guide.
LEDs Status LEDs, 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
