Cables and connectors

• You can install any transceiver supported by the PIC.
• Fiber-optic small form-factor pluggable (SFP) transceivers:
  • Duplex LC/PC connector (Rx and Tx)
  • 1000BASE-LH (model number: SFP-1GE-LH)
  • 1000BASE-LX (model number: SFP-1GE-LX)
  • 1000BASE-SX (model number: SFP-1GE-SX)
  • Optical interface specifications—see Ethernet 10BASE, 100BASE, and 1000BASE Copper and Optical Specifications
  • 1000BASE-BX (model number pairs: SFP-GE10KT13R14 with SFP-GE10KT14R13, SFP-GE10KT13R15 with SFP-GE10KT15R13, SFP-GE40KT13R15 with SFP-GE40KT15R13)—See Bidirectional SFP Optical Interface Specifications
• Copper transceiver:
  • Connector: Four-pair, Category 5 shielded twisted-pair connectivity through an RJ-45 connector
  • 1000BASE-T (model number: SFP-1-GE-T)
  • Pinout: MDI crossover
  • Copper interface specifications—see Ethernet 10BASE, 100BASE, and 1000BASE Copper and Optical Specifications

Note: Do not install SONET/SDH OC48c/STM16 SFPs in a Gigabit Ethernet port. The port will not recognize the SFP.

LEDs

Status LED, one tricolor:

• Off—Not enabled.
• Green—Online with no alarms or failures.
• Yellow—Online with alarms for remote failures.
• Red—Active with a local alarm; router has detected a failure.

Note: The green Status LED is lit on the 2-port Gigabit Ethernet IQ PIC when at least one port is online.

Port LEDs, one per port:

• Off—Port is down.
• Green—Link is established.
