4.2 Troubleshooting
If the BCI 4900 units do not operate properly after installation,
check for possible cable breaks, loose connections, and
incorrect cable connections. If a problem exists on the fiber
link, please check your fiber connectors for improperly cleaned
fiber cables and connectors. If problems persist that may be
fiber related, contact BCI at 1-800-214-0222 for further
assistance.
For electrical problems, perform the following troubleshooting
procedures:
1. If the POWER indicator is OFF, check for the following:
a. The line cord is plugged into the unit and your outlet
has power.
b. The 4900 unit is powered on.
2. If the POWER indicator is ON, but the Optical Link
indicator is OFF, check for the following:
a. Make sure the appropriate (Singlemode or Multimode)
fibers are being used.
b. Fiber and fiber connectors are not broken. Ensure that
the optical loss does not exceed the specified optical
power attenuation (see Section 5.0 Specifications for
the optical power budget).
