Software release

• 1-port: Junos OS Release 8.0R2 and later (Type 1)
• 2-port: Junos OS Release 8.0R2 and later (Type 2)
• 4-port: Junos OS Release 8.0R2 and later (Type 2)
• 10-port: Junos OS Release 8.0R2 and later (Type 3)

Note: These PICs are not supported in Junos OS Release 8.1R1.

For information on which FPCs support these PICs, seeM120 PIC/FPC Compatibility .

Description

• One, two, four, or ten Gigabit Ethernet ports
• Power requirement:
  • 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

Software features

• Virtual Router Redundancy Protocol (VRRP) support
• 802.1q virtual LANs (VLANs) support
• 960 destination MAC filters per port
• Optical diagnostics and related alarms on the 2-port, 4-port, and 10-port PICs (Junos OS Release 8.2 and later)
• Flexible Ethernet encapsulation on the 1-port, 2-port, and 4-port PICs
• Multiple tag protocol identifiers (TPID) support on the 1-port, 2-port, and 4-port PICs
• Source MAC learning on the 1-port, 2-port, and 4-port PICs
• MAC accounting and policing—Dynamic local address learning of source MAC addresses on the 1-port, 2-port, and 4-port PICs

Note: The 10-port Gigabit Ethernet PIC with SFP does not support MAC accounting and policing, MAC learning, TPID, or flexible Ethernet encapsulation.

LEDs

Status LED, 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.
