Juniper Networks M120 manual One, two, four, or ten Gigabit Ethernet ports

Gigabit Ethernet PICs with SFP

Software release	■	1-port: JUNOS 8.0R2 and later (Type 1)
	■ 2-port: JUNOS 8.0R2 and later (Type 2)
	■ 4-port: JUNOS 8.0R2 and later (Type 2)
	■	10-port: JUNOS 8.0R2 and later (Type 3)

NOTE: These PICs are not supported in JUNOS Release 8.1R1.

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
Hardware features	■	High-performance throughput on each port 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
	■ 960 destination MAC filters per port
	■ Optical diagnostics and related alarms on the 2-port, 4-port, and 10-port PICs (JUNOS
		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.
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.
	■ Fiber-optic SFP transceivers:
		■ Duplex LC/PC connector (Rx and Tx)
		■ Optical interface support—See Table 15 on page 62
	■	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

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