manual abstract
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 (Unterminated Port Status Board Active Error Error 1234567 8 For a description of how to configure this module into your network, see the LANplex documentation set. Audience This guide is intended for trained technical personnel only. 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. . LED Name Color Description Module Board Error Yellow Indicates that either an error has occurred or the Status option module has failed a diagnostic procedure Port Active Green Indicates that the associated port is active Status Error Yellow Indicates that an error condition has occurred with the associated port or that the port was disabled from the Administration Console Safety Information Prior to Installation Read if initial installation Electrostatic discharge (ESD) can damage components on the module. ESD occurs when the module is improperly handled and can cause complete or intermittent failures. To prevent ESD-related damage: ¦ Always wear the ESD wrist strap provided with the LANplex system, ensuring that it makes good skin contact ¦ Keep the module in its antistatic shielded bag until you are ready to install it ¦ Do not touch the components, pins, leads, or solder connections ¦ Always handle the module by its edges Before you install your new module, follow the appropriate pre-installation instructions in this section. Your LANplex system is shipped with protective faceplates covering the exposed installation slots. You must remove the protective faceplate covering the selected installation slot prior to installing the option module. CAUTION: When handling modules, 3Com recommends that you always use a wrist strap connected to a proper ground. This helps prevent the module from being damaged by electrostatic discharge. Additionally, when not in use, the module should be stored in an antistatic bag. To remove the faceplate: 1 Loosen the two captive screws securing the faceplate to the chassis. 2 Pull the faceplate away from the system. Captive screw Faceplate Power Run Processor Power Fan Temp Config Inserted ERROR PCMCIA LANplex 2500R Captive screw Read if replacing You can replace a module while the system is powered on. Replacing the a module module requires that you remove the attached cables from the module’s ports prior to installing the new module. To replace a module: 1 Disconnect the cables from the module’s ports. 2 Loosen the two captive screws securing the module to the chassis. 3 Pull the module out of the chassis.

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. For information on defining an IP inter- face, see the Administration Console User Guide for your LANplex system.
