Chapter 5 Hardware Fault Analysis
The part describes how to remove the fault from the GPON access device.
The key for resolving the systematic faults is to separate the fault from the system. You
can compare what the system is doing with what the system should do to detect the
fault. You need to check the following subsystems:
Power supply—providing the power
Port, cable and connection—ports on the front template of the GPON access
device and the cables connecting these ports
5.1.1 Performing the Following Power-Supply Steps
If the GPON access device is too hot, check whether the air outlet and air inlet
are clean and then do relative operations in section 2.3 “Requirements for
Common Locations”. The temperature of the locale where the GPON access
device runs should be from 0℃ to 50℃.
If the GPON access device cannot be started and the PWR indicator is off, check
the power.
5.1.2 Faults Relative with Port, Cable and Connection
Do the following checkups to help remove the fault:
If the port of the GPON access device cannot be linked, check whether the cable
is correctly connected and whether the peer connection is normal.
If the console port does not work after the system is started up, check whether
the console port is set to a baud rate of 9600 bps, eight data bits, no sum check
bit, one stop bit and no traffic control.
5.2 Indicator Description
The LEDs are used to show what operations are conducted by the GPON access
device. For the LEDs of BDCOM GP3600-08 GPON and their description, see the
following table:
When the device is powered on, the
indicator is on.
