4. Verify that a link exists by checking that the port RX LED is on (flashing amber, blinking green,
or solid green). If the RX LED is off, perform the following steps until it is on:
a. Verify that the device at the other end of the segment is ON and connected to the segment.
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 fiber optic cabling. To obtain this document, refer to
Section
1.6.
If a link has not been established, refer to
problem persists, refer to
Enterasys Networks for support.
5. Repeat steps 1 through 3, above, until all connections have been made.

Connecting Fiber Optic Cables to an SC Port
The optional ZPIM1-01 and 10GBASE-LR have an SC style connector for a cable connection to a
10-Gigabit Ethernet network. Enterasys Networks offers fiber optic cables that use SC style
connectors, which are keyed to ensure proper crossover of the transmit and receive fibers.
Note: An odd number of crossovers (preferably one) must be maintained between like devices so
that the transmit port of one device is connected to the receive port of the other device and vice
versa.
3.9.3
Network Connection Using Fiber Optic Cable
The following instructions apply to SC connections of either the ZPIM1-01 or 10GBASE-LR
module installed in a ZPIM1-06. In this procedure connection to ZPIM1-01 is used as an example.
To connect the switch to the network, perform the following steps:
1. Remove any protective covers from the fiber optic ports and from the ends of the connectors.
