LE7500A MODULES
Installing the Intelligent Media Converter Modules
• The LE7501A Management Module can only be installed in the far
right-hand slot. See diagram.
• Intelligent “redundant twister”
™
modules have DIP switches that must
be set prior to installation. Refer to the
Intelligent Media Converter
“redundant twister” Module Installation & User Guide
for more details.
• Intelligent “redundant twister” F/O modules require two slots.
• Modules must be firmly secured to the chassis before network
connections are made.
Follow the simple steps outlined below:
1. Grasp a module by the front panel as shown and insert into a slot
making sure that both the top and bottom of the card edges are lined
up with the top and bottom card guides.
2. Slide the module in until the top and bottom edges of the front panel
are flush and even with the top and bottom edges of the chassis and
secure to the chassis by turning the thumb screw clockwise until snug.

• LINK Switch UP: module sends link on both the PRIMARY and SECONDARY ports; the end station connected to the module sees a valid link state.
• LINK Switch DOWN (default): module sends link on the active port only;
the end station connected to the module sees a valid link state only if the
port on the module is active.
• LLCF Switch UP: Link Loss Carry Forward is enabled.
• LLCF Switch DOWN (default): Link Loss Carry Forward is disabled.
• RED Switch UP (default): redundancy is enabled; Operates in Dynamic
Recovery Mode (DRM).
• RED Switch DOWN: redundancy is disabled; Network Select Mode (NSM)
is enabled. NOTE: In this mode the reset push button toggles the active
port between A and B for each switch closure. The AUTO switch sets the
initial active port on power up: UP for SECONDARY; DOWN for
PRIMARY. The SW LED remains OFF in NSM.
DIP switches can be managed with console commands or with NetBeacon
™
Management Software. Refer to the Intelligent Media Converter™ Command
Line Interface Guide, or the NetBeacon
™
Management Software
Installation & User Guide for software management information. For more
information on the Intelligent “redundant twister” modules, refer to the
Intelligent Media Converter “redundant twister”™ Installation & User
Guide.
LE7501A Management Module

agent reports individual board status to the network management software.
TP Data Rate: 10Mbps half-duplex; 20Mbps full-duplex
LED Operation:
• (TP) LK: link present
• (TP) AT: link present and packet received
• PWR: power supply present and ON
• (Console) A: power supply A present and ON
• (Console) B: power supply B present and ON
• (Console) R: system is operational
• (Console) ER: indicates system diagnostics or boot failure
PC Terminal Session Parameters:
9600 Baud / 8 data bit / 1 stop bit / No Parity / No Flow Control
Refer to the Intelligent Media Converter
™
LE7500A Installation & User
Guide for information on booting the LE7501A Management Module. Refer
to the Intelligent Media Converter
™
Command Line Interface Guide for
the software commands.
IMPORTANT: When setting DIP Switches: UP is furthest from the circuit board.
DOWN is closest to the circuit board.
NOTE: Link Loss Carry Forward (LLCF) functionality is incorporated on all intelligent twister modules with the exception of the LE7111A-BNC
module. Refer to the
