3.4 CONNECTING TO THE NETWORK
This section provides the procedures for connecting fiber optic and
twisted pair segments from the network or other devices to the 6H12X-08.
Ports 1 through 6 have SC connectors for fiber. The 6H128-08 supports
multimode fiber, and the 6H129-08 supports single mode fiber. Ports 7
and 8 support FE-100TX, FE-100FX, or FE-100F3 Fast Ethernet
Interface Modules. The FE-100TX has an RJ45 connector for a Twisted
Pair cable connection. The FE-100FX and FE-100F3 have SC connectors
for fiber optic cable connections.
Refer to Section 3.4.1 to make fiber connections to ports 1 through 6.
Refer to Section 3.4.2 to make a twisted pair connection to an FE-100TX
in port slot 7 or 8.
Refer to Section 3.4.3 to make a fiber optic cable connection to an
FE-100FX or FE-100F3 in port slot 7 or 8.
3.4.1 Connecting Fiber Optic Cables to Ports 1
Through 6
Ports 1 through 6 of the 6H12X-08 have SC style network ports (see
Figure 3-2 ). Cabletron Systems supplies fiber optic cable that uses SC
style connectors that are keyed to ensure proper crossing over of the
transmit and receive fibers. The 6H128-08 is designed for use with
multimode fiber, and the 6H129-08 is designed for use with single mode
fiber. Use of the incorrect fiber type may cause network problems. Please
refer to the Cabletron Systems Cabling Guide for further information.
NOTE
If the 6H12X-08 is being installed in a network using
SmartTrunking, there are rules concerning the network cable
and port configurations that must be followed for
SmartTrunking to operate properly. Before connecting the
cables, refer to the
SmartTrunk User’s Guide for the
configuration information.
