4.1 Problems, Causes, and Solutions
Problem:
All of the LEDs on the local or remote unit are not lit.
Probable cause:
The unit is not receiving power.
Possible solution:
Make sure the power supply is securely connected to both the
unit and a working AC outlet.
Problem:
The Link LEDs on the local and remote units are not lit.
Probable cause:
The connection between the local and remote units is not correct.
Possible solution:
Make sure that a standard duplex 50/125-µm or 62.5/125-µm
multimode or 9/125-µm single-mode fiberoptic cable is securely connected to both
the local and remote units, and make sure that each strand of the cable runs from
TX on one end to RX on the other end.
Problem:
The host LED on the local unit and the device LEDs on the remote unit
are not lit.
Probable causes:
Either the USB link between the local unit and the host
computer is not correct, the computer isn’t functioning, or the computer doesn’t
recognize the RemotePort.
Possible solutions:
1. Make sure that the USB cable between the host computer and local unit is
securely connected.
2. Unplug the local unit’s power supply and then plug it back in.
3. Reset or reboot the computer.
4. If the computer consistently fails to recognize the RemotePort as a “Generic
USB Hub,” call Black Box Technical Support as directed in
Section 4.2
