NTERMINATED

10BASE-2 (BNC)

ODULE

For the LANplex 2500/2016

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).
