4
Installation
The media module comes equipped with a bank of DIP switches
and jumpers for setting configuration. The default DIP switch
settings (all switches in the UP position) and jumper settings will
work for most installations.
The following steps are used to configure the Perle Fast Media
Converter Module:
•Set the Auto-Config jumper. (CM-100MM only) (optional)
•Set the DIP switch settings. (optional).
•Insert the media module into the chassis.
•Connect fiber cable 1 to port MM1.
•Connect fiber cable 2 to port MM2/SM2.
Auto-Config Jumper (CM-100MM only)
The Auto-Config jumper is J5.
Refer to the diagram below for labelling. This jumper only applies
to the CM-100MM converter module.
Auto (Pin 2 and Pin 3 are strapped): When set to Auto. At power
up the media module will, check its internal flash memory to see if
configuration information has been downloaded to it from a
management module. If so, the media module will use this
configuration as its running configuration. If there is no
configuration in flash, the media module will read the settings of
the DIP switches and use those settings as its running
configuration.
SW (Pin 1 and Pin 2 are strapped): When set to SW (Switch). At
power up, the media module will read the settings of the DIP
switches and use those settings as its running configuration. The
media module will ignore any configuration information in its flash
memory.
Note: The default jumper setting is Auto
