Configure
FiberAlert
on
McBasic TX/FX
by adjusting a two-position switch,
labeled FA, on the faceplate next to the fiber connectors. Enable this fea-
ture by moving the switch to the up (ON) position. Disable (default) by
moving the switch to the down (OFF) position.
Auto-Negotiation on McBasic TX/FX
Auto-Negotiation
is available on
McBasic TX/FX
. When
Auto-Negotiation
is enabled, the media converter negotiates as a 100 Mbps Full-Duplex
device; if the device the
McBasic TX/FX
is connected to can operate at 100
Mbps Full-Duplex, a link will be established.
If the twisted pair port on the other device does not have the ability to
auto-negotiate, or if a 100 Mbps Half-Duplex connection is desired,
Auto-
Negotiation
on
McBasic TX/FX
must be disabled. Half- and Full-Duplex set-
tings must be manually set and match on both devices to which
McBasic TX/FX
is connected. The diagram below shows a typical applica-
tion, followed by a table with three possible configurations.

Installation Troubleshooting
• During installation, test your fiber and twisted pair connections with
FiberAlert
disabled. Then enable
FiberAlert
, if desired, just before final
installation. This will reduce the feature’s interference with testing.
