5.0 TROUBLESHOOTING
If problems should develop during installation or operation, follow the
suggestions below prior to calling Technical Support for help. If you are unsure of
any procedure described in this chapter, or if the 4-port BNC Repeater is not
operating as expected, do not attempt to repair or alter the unit. Contact Black Box
for assistance.
5.1 Before Calling for Assistance
1. If you have difficulty installing or operating the 4-port BNC Repeater, refer to
Chapters 3 and 4. Make sure the other components of the network are working.
2. Check the cables and connectors to make sure that they have been properly
connected and have not been crimped or in some way impaired during installation.
3. Check that the AC power cord is plugged into a functioning electrical outlet.
Make sure that the AC power cord is properly plugged into the 4-port BNC Repeater. Use
the PWR LED to verify that the unit is receiving proper power.
4. If the problem is isolated to a network device other than the 4-port BNC
Repeater, replace the problem device with a known good device. Verify whether or not the
problem is corrected. If it is not, go to step 5. If the problem is corrected, the 4-port BNC
Repeater and its associated cables are OK.
5. If the problem still exists, contact Black Box.
