Chapter 3: Installation
3.5CONNECTING 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.
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.
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.
3.5.1Connecting 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.
