3.5 CONNECTING TO THE NETWORK
This section provides the procedures for connecting fiber optic segments
and twisted pair from the network or other devices to the 2H28-08R.
Ports 1 through 6 on the 2H28-08R have SC connectors for fiber
connections. The 2H28-08R supports multimode fiber optic cable. 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; multimode for the FE-100FX, and
single mode for the FE-100F3.
Refer to Section 3.5.1 to make fiber connections to ports 1 through 6.
Refer to Section 3.5.2 to make a twisted pair connection to an FE-100TX
in port 7 or 8.
Refer to Section 3.5.3 to make a fiber optic cable connection to an
FE-100FX or FE-100F3 in port 7 or 8.
3.5.1 Connecting Fiber Optic Cables to Ports
1 Through 6
Ports 1 through 6 of the 2H28-08R have SC style network ports (see
Figure 3-6 ). 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 2H28-08R is designed for use with
multimode fiber optic cable. Use of the incorrect fiber type may cause
network problems. Refer to the Cabletron Systems Cabling Guide for
further information.
NOTE
If the 2H28-08R 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. Refer to the Cabletron
Systems
SmartTrunk User’s Guide for additional information.
