Installation—Continued
AutoCross jumper
(model 140 only)
The AutoCross feature allows either straight-through (MDI) or crossover (MDI-X)
cables to be used when connecting to 10Base-T, 100Base-TX, or 1000Base-T
devices, such as hubs, transceivers, or network interface cards (NICs). AutoCross
determines the characteristics of the cable connection and automatically configures
the unit to link up to its companion device regardless of the cable configuration.
The AutoCross jumper is the three-pin header J6 on the circuit board
(labeled NA = No
Autocross and A = AutoCross).
See Jumper positions below.
Note:
Use small needle-nose pliers to set the jumper.
A
Either straight-through or crossover cable can be
used for all twisted-pair copper links.
NA
Straight-through or crossover twisted-pair cable,
depending on installed site devices, MUST be
installed at EACH end of the twisted-pair copper
link.
Note:
Factory default is “A” enabled. Transition Networks recommends leaving
the jumper in the “enable” position.
