Expansion Module
the frame number will not be changed. A message will be logged in the Error Logger
notifying the user of the switch change (specifying the actual frame number.)
If the frame number was set to a number other than 1-9/A-D before power-up, the
expansion module will restart itself continually until the frame number is changed.
The MERR LED will be red, but no error is logged. The invalid number (1-15) will
be reflected in the Expansion Address LEDs.
If the frame number is changed after the Expansion Loader has begun discovery, but
before the Expansion Image is started, the expansion module will restart itself and use
the new frame number (assuming it is 1-9/A-D.)
It is recommended to set the frame numbers in sequential order (i.e. frame number 1
connected to the expansion LAN switch port Eth2, frame number 2 connected to
expansion LAN switch port Eth3, etc.)
0 is an illegal frame number and is not represented by the EXP ADDR LEDs.
