  Copper interface specifications—see Ethernet 10BASE, 100BASE, and 1000BASE Copper and Optical Specifications

• Bidirectional SFP transceivers:
  • Connector: Duplex LC/PC (Rx and Tx)
  • 1000BASE-BX (model number pairs: SFP-GE10KT13R14 with SFP-GE10KT14R13, SFP-GE10KT13R15 with SFP-GE10KT15R13, SFP-GE40KT13R15 with SFP-GE40KT15R13)

  Optical interface specifications—see Bidirectional SFP Optical Interface Specifications

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

LEDs

OK/FAIL LED, one bicolor:

• Steady green—DPC is functioning normally.
• Blinking green—DPC is transitioning online or offline.
• Red—DPC has failed.

Link LED, one green per port:

• Off—No link.
• On steadily—Link is active.

The Link LEDs are labeled in groups of five:

• 0/0 for 0/0 through 0/4
• 0/5 for 0/5 through 0/9
• 1/0 for 1/0 through 1/4
• 1/5 for 1/5 through 1/9
• 2/0 for 2/0 through 2/4
• 2/5 for 2/5 through 2/9
• 3/0 for 3/0 through 3/4
• 3/5 for 3/5 through 3/9
