Connecting to the Network
b.If there are separate fiber‐optic connections on the other device, check the crossover of the cables. Swap the cable connections if necessary.
c.Check that the fiber‐optic connection meets the dB loss and cable specifications outlined in the Cabling Guide for multimode cabling. To obtain this document, refer to “Related Documents” on page xvi.
If a link has not been established, refer to Chapter 4 for LED troubleshooting details. If a problem persists, refer to “Getting Help” on page 1‐8 for details on contacting Enterasys Networks for support.
5.Repeat steps 1 through 4, above, until all connections have been made.
Connecting Fiber-Optic Cables to LC Ports
Warning:
Advertencia: Los
Warnhinweis:
This section describes how to connect
•a 1000BASE‐SX multimode fiber‐optic segment from the network or other devices to an LC port connector of a Mini‐GBIC (MGBIC‐LC01), or
•a 1000BASE‐LX single‐mode fiber‐optic segment from the network or other devices to an LC port connector of a Mini‐GBIC (MGBIC‐LC09).
Each fiber‐optic link consists of two fiber‐optic strands within the cable:
•Transmit (TX)
•Receive (RX)
The transmit strand from a switch port connects to the receive port of a fiber‐optic Gigabit Ethernet device at the other end of the segment. The receive strand of the applicable LC port connects to the transmit port of the fiber‐optic Gigabit Ethernet device.
Enterasys recommends labeling fiber‐optic cables to indicate receive and transmit ends. Many cables are pre‐labeled, providing matching labels or tapes at both ends of each strand of cable.
