Auto-Config Jumper (CM-1110 only)
The Auto-Config jumper (J5) is located just above the Auto-MDIX
jumper (see above). Refer to the diagram below for labelling. This
jumper only applies to CM-1110 modules.
Strapping pins 1 and 2 of the jumper will set the module in SW
mode and strapping pins 2 and 3 will set it in Auto Config mode.
Auto: When set to Auto the module will, at power-up, check its
internal flash memory to see if configuration information has been
downloaded to it from a management module. If so, it will use this
as its running configuration. If there is no configuration in flash it
will read the settings of the DIP switches and use those as its
running configuration.
SW: When set to SW (Switch), the module will, at power-up, read
the settings of the DIP Switches and use those as its running
configuration. It will ignore any configuration information in its flash
memory.
Note: The default jumper setting is Auto
Dip Switches
