Interfaces

Syntax: ge-fpc/pic/port where:

• fpc: Slot in the router where the DPC is installed
• pic:

20-port: 0 (left row of 10 ports), or 1 (right row of 10 ports)

40-port: 0 (bottom left row of 10 ports), 1 (bottom right row of 10 ports), 2 (top left row of 10 ports), or 3 (top right row of 10 ports)

• port: 0 through 9

For example, ge-1/1/0 is the interface for port 0 in the (top for 40-port) right row of 10 ports on a DPC installed in slot 1.

Cables and connectors

• You can install any transceiver supported by the DPC. For information about installing and removing transceivers, see the hardware guide for your router.
• Fiber-optic small form-factor pluggable (SFP) transceivers:

Connector: Duplex LC/PC (Rx and Tx)

1000BASE-EX (model number: SFP-GE40KM)

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 Gigabit Ethernet 1000BASE Optical Interface Specifications
• Copper SFP transceivers:

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

1000BASE-T (model number: SFP-1GE-T)

Pinout: MDI crossover

Length: 328 ft/100 m

• Copper interface specifications—see Gigabit Ethernet 1000BASE-T Copper Interface 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 Fast Ethernet and Gigabit Ethernet 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:

• 20-port:
  • 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
• 40-port:
  • 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
