program.
No. Jumper
Short-
circuited S1
Short-
circuited S2
Short-
circuited S3
Only one of S1, S2, and S3 should be short circuited while others should be
disconnected.
If all of S1, S2, and S3 are disconnected, the default value is No.1 upon startup.
If two or all of S1, S2, and S3 are concurrently short circuited, the default value is
according to priority: S1 > S2 > S3.
To configuring default value, configuring jumper is of lower priority than
configuring through network management; it becomes invalid after the
configuration through network management takes effects.
