Step 1:
Connect the media converter to the twisted
pair device with a twisted pair cable.
Step 2:
Loop a single strand of fiber from the transmit
port to the receive port of your media converter.
Step 3:
Verify that you have both twisted pair and fiber
link (see LEDs, page 5) on your media converter.
• Make sure to use the appropriate twisted pair cable, and have the
crossover/pass-through switch set correctly, if your link partner does
not include
AutoCross .
• If using a high powered device (which is designed for long distance
installations) for a short distance installation, the fiber transmitters
may overdrive the receivers and cause data loss. If this is the case,
you may need to add an optical attenuator to your connection.

Use Pulsing FiberAlert in the following two situations:
A) When connecting two PoE Compact Media Converters (or con-
necting a PoE Compact Media Converter to a Black Box 100 Mbps
modular media converter ) with FiberAlert enabled.
B) When connecting one PoE Compact Media Converter with
FiberAlert enabled and one Black Box Media Converter with Link Fault
Detection (LFD) enabled.
NOTE: Pulsing FiberAlert may be useful when connecting PoE Compact Media Converter to
another manufacturer’s product that has a similar feature to FiberAlert.
NOTE: Please refer to the Installation Guide for the appropriate Black Box product for more
information on LFD.
Auto-Negotiation on
PoE Compact Media Converter
PoE Compact Media Converters include Auto-Negotiation . When Auto-
Negotiation is enabled (default), the media converter negotiates as a 100 Mbps
Full-Duplex device; if the device the PoE Compact Media Converter is connect-
ed 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-
Converter 1 Converter 2

NOTE
FiberAlert is not available/applicable on single-strand fiber versions of
PoE Compact Media Converter.

Enable FiberAlert on only ONE side of a media conversion; enabling it on both
sides will keep both transmitters off indefinitely. If you want to enable FiberAlert
on BOTH sides of the conversion, you MUST also enable
Pulsing FiberAlert on
one unit. Black Box recommends enabling Pusling FiberAlert on ONE side (see
page 5).
