Gigabit Ethernet Copper/SFP MIC

Software release

  • Junos OS Release 12.3x51-D10 and later

Description

  • 6 tri-speed (10/100/1000 Mbps) ports, either RJ-45 or SFP

  • Supports large Ethernet frame sizes for more efficient throughput across the intra-POP network

  • Power requirement without PoE: 1.5 A @ 12 V (18 W)

  • Weight: 1.2 lb (0.54 kg)

  • Model number: ACX-MIC-6GE-CU-SFP

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

  • PoE Gigabit Ethernet ports that provide 32 W of electrical current per port to devices (limited to 170 W per chassis).

  • Ports are numbered 0 through 5

Software features

  • Optical diagnostics and related alarms

  • Virtual Router Redundancy Protocol (VRRP) support

  • IEEE 802.1Q virtual LANs (VLANs) support

  • Remote monitoring (RMON) EtherStats

  • Source MAC learning

  • MAC accounting and policing—Dynamic local address learning of source MAC addresses

  • Flexible Ethernet encapsulation

  • Multiple tag protocol identifiers (TPID)

Cables and connectors

RJ-45 ports:

  • Connector: Four-pair, Category 5 shielded twisted-pair connectivity through an RJ-45 connector

  • Pinout: MDI, MDI crossover

  • Maximum distance: 328 ft/100 m

  • Supported interface standards:

    • 1000BASE-T

    • 10/100/1000BASE-T

Tip:

You can use the Hardware Compatibility Tool to find information about the pluggable transceivers supported on your Juniper Networks device.

Note:

To extend the life of the laser, when a MIC is not being actively used with any valid links, take the MIC offline until you are ready to establish a link to another device. For information about taking a MIC offline, see the request chassis pic offline command in the CLI Explorer.

LEDs

OK/FAIL LED, one bicolor:

  • Green—MIC is functioning normally

  • Red—MIC has failed

Port link LEDs:

  • Activity—If the LED is blinking green, the port is sending or receiving data; if there is no light, the port is down or is not active.

  • Link—If the LED is yellow, the port link is up; if there is no light, the port links is down.
