Atom GPS Troubleshooting

Atom GPS Troubleshooting

Frequency/Time Locking Failure of the Atom GPS System

Common Causes
Common causes are as follows:
  • The GPS satellite incorrectly receives signals.
  • A hardware error exists in the module.
Troubleshooting Procedure

Procedure

  1. Check whether the Atom GPS module is running properly.

    Run the display smart-clock interface interface-name command to check the running status of the Atom GPS module.

    • If the values of the Freq lock success and Time lock success fields are yes, check whether the GPS feeder is damaged, whether the connector loosens, and whether the GPS antenna is blocked or interfered. If the fault persists, go to Step 3.

    • If the values of the Freq lock success and Time lock success fields are no, the frequency and time of the module become out of lock. In this case, go to Step 2.

  2. Reset the Atom GPS module.

    Run the reset smart-clock command to reset the Atom GPS module and wait for 10 minutes.

    • View clock locking information. If both the frequency and time are locked, the fault is rectified.

    • View clock locking information. If the frequency and time are still out of locked, go to Step 3.

  3. Collect the following information and contact Huawei technical support personnel:

    • Results of the preceding procedure

    • Configuration, log, and alarm files of the device

Failure to Interconnect a 1588v2/G.8275.1-capable Device and an Atom GPS Module

Common Causes
Common causes are as follows:
  • The 1588v2/G.8275.1 configuration on the device does not match the Atom GPS module configuration.
  • The Atom GPS module time is not locked to the GPS time.
Troubleshooting Procedure

Procedure

  1. Check whether the time is locked to the GPS time.

    Run the display smart-clock interface interface-name command to check the running status of the Atom GPS module.

    • If the value of neither the Freq lock success nor Time lock success field is no and the value of the clock-class field is 6, go to Step 2.

    • If the values of both the Freq lock success and Time lock success fields are no and the value of the clock-class field is not 6, the clock source is invalid. In this case, go to Step 4.

  2. Check whether the domain where the device resides is the same as that of the Atom GPS module.

    Run the display ptp all command to check whether Domain value of the device is the same as that of the Atom GPS module.

    • If not, run the ptp domain domain-value command as planned to configure the device and Atom GPS module to be in the same clock domain. If the fault persists, go to Step 3.

    • If yes, go to Step 3.

  3. (Only for G.8275.1)Check whether the notslave attribute of the interface is false.

    Run the display ptp all config command to check whether the ptp notslave disable command is set for interfaces on both sides.

    • If not, run the ptp notslave disable command in the interface view as planned. If the fault persists, go to Step 4.

    • If yes, go to Step 4.

  4. Collect the following information and contact Huawei technical support personnel:

    • Results of the preceding procedure

    • Configuration, log, and alarm files of the device
