TROUBLESHOOTING
If the following instructions fail to solve your problem, contact Pelco Technical Support at
1-800-289-9100 for help. You should have the serial number from the bottom of the unit and the
firmware version ready in case they are needed.
Do not try to personally repair a unit. Opening it immediately voids any warranty. Leave mainte-
nance and repairs to qualified technical personnel. Swap a defective unit with a replacement unit
and return the defective one for repair.
BASIC FUNCTIONING
LEDs on the unit indicate its condition. The following sections describe malfunctions indicated by
the LEDs.
Green Power LED
Green Power LED Is Off
If the green power LED on the front panel is off and you believe it should be blinking, check the
following:
• Make sure the enclosed power supply is connected correctly to the power plug socket.
• Make sure the power supply is connected correctly to a functioning power outlet.
• Check the power cord for apparent damage.
• Check the power supply for a 5 VDC output. If it is correctly connected and the green power
LED still does not light, exchange the power supply for a new one.
Green Power LED Blinks Slowly
This does not indicate a malfunction but means a connection exists between one unit and another.
Connections with a web browser have no effect on this LED, so there will be no blinking light
during configuration.
Green Power LED Lit
This indicates the NET104A is on but there is no connection.
Green Power LED Stays Off After Firmware Upload And Reprogramming
If the power LED does not come back on after a firmware upload, there may have been a problem
during upload. Return the system to the dealer.
Closely follow the instructions for the firmware upload. Especially do not disconnect the power
supply during firmware upload and reprogramming.
