Feature Description
AutoCross When the AutoCross feature is active, it allows the use
of a straight-through (MDI) or crossover (MDI-X)
copper cable when connecting to 10/100Base-T or
10/100/1000Base-T Devices. AutoCross determines the
characteristics of the connection and configures the
Devices to link up automatically. This occurs regardless
of the cable configuration: MDI or MDI-X. (Transition
networks recommends leaving AutoCross in default
mode, “enabled.”)

Automatic Firmware
Upgrades
The Device has an automatic firmware upgrade feature.
This feature applies to a communication link between a
local peer and its remote peer Devices connected via a
fiber optic cable. If the remote passive peer Device is not
in Active Mode and a local active peer Device detects a
different firmware revision on its remote passive peer
Device, the local active Device will force a bootload
condition and download its firmware revision to its
remote passive peer Device.
Note The local Device could have a different firmware
revision (newer or older) than its remote peer. In
either case, the firmware revision on the local
Device will replace that of its remote passive
peer.
Note: The firmware of the local active peer Device
should be upgraded before the remote passive
peer Device to ensure that the correct firmware
version is on both Devices.
