Module Description

This module contains eight (8) unterminated Ethernet 10BASE-2 ports that
use BNC connectors. I

f a port on this module is at the end of a 10BASE-2

(BNC) segment, you must provide an external 50 Ohm terminator.

When the port is at the end of a segment, using a T connector with a
terminating plug may cause interference with adjacent ports. 3Com
recommends terminating ports with the ITT Pomona Y connector, Model
4896, with a terminating plug on the end, or the ITT Pomona Feed-Thru
Terminator, Model 4119-50. When the port is in the middle of a segment, the
Y connector may be necessary.

Prior to installing the unterminated 10BASE-2 (BNC) module, LANplex
system software revision 7.0.0 or later and LANplex diagnostics software
revision 3.0.2 or later must be installed. A system software revision
supporting this module is available from the 3com BBS, the Internet FTP site
(3Com.ftp.com), or 3Com Forum on Compuserve, or 3Com’s Web site
(http://infodeli.3com.com/infodeli/swlib/switch_files.htm).

For a description of how to configure this module into your network, see
the LANplex documentation set.
