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 IT T Pomona Y connector, Model
4896, with a terminating plug on the end, or the IT T 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.

Summary
Status LEDs The option module contains one Board Error LED, eight port status Active LEDs, and eight port status Error LEDs. Depending on the condition, the port status LED is either Active (green) or Error (yellow). See the table below for a description of the status LEDs. . Safety Information Elec...
The LANplex system will automatically reset when a module has been installed with the power on. If you physically change the configuration of the system after defining an IP interface, the port designated for that interface may no longer be valid. You may have to redefine the interface.

4 To seat the module, firmly push the module forward to engage the module and backplane connectors. You will feel a slight resistance as the connectors engage. CAUTION: If the resistance is too great, the module and backplane connec- tors may not be aligned. Forcing the module forward could damage t...
