ID LEDs
The two ID LEDs are used to identify the module’s chassis ID number.
This number, which, as explained in “Chassis ID Jumper” on page 66, is
set with the jumper on the board and is used in the management
commands to identify the chassis. A management module can have the
value 0 or 31. If the ID LED 0 is on, the module and the chassis have the
ID number 0. If the ID LED 31 is on, then the module and chassis have the
ID number 31.
