Viewing the Device Status

Sensors and TDUs that are connected to the network, and receiving power through Power-over-Ethernet (PoE), will have Running status if you have:

  • Created the required Geometry Cells and Location Cells.

  • Positioned the devices within Location Cells.

  • Configured network and timing for the devices.

The actual status of the sensors in the different Location Cells will differ depending on the completeness of the configuration.

To view the status of a sensor or TDU, click the View sensor status tab.

Device Statuses

A device that has Running status has booted successfully.

The following statuses indicate that you have configured the device but there is a specific problem that you need to resolve:

Status Description

Last seen booting

The device was rebooted at the specified date and time. This means one of the following:

No timing signal

The device has booted successfully, but is not receiving a timing signal.

These statuses indicate a more fundamental problem:

Status Description

Last seen...

With the exception of Last seen booting, there is problem preventing the system from reporting the current status. For example, there may be no network connection.

No geometry cell

No location cell

The device is not located in a geometry cell or location cell so it cannot obtain its configuration settings from the server. It will continue to reboot until it has obtained its configuration.
Unknown The device may not be connected to the network.

Notes on the View sensor status tab:

  • The Status Age indicates the duration for which the device has been in its current status.

  • You can sort sensors by clicking the column headings.

  • You can group sensors by using the Group by option.

  • You can optionally add comments to individual devices or sets of devices.

  • A command-line tool ubisense_ls_sensor_status can be used to print a similar table of sensor statuses, optionally filtered by the sensors' last reboot times. This can be downloaded from the Ubisense Application Manager in Ubisense > Location system > Administration tools.

Adding Comments to Devices

You can add a comment to one or more devices listed on the View sensor status tab.

To add a comment to a single device—double-click the device to open the editor.

To add a comment to several devices:

  1. Press the Shift or Ctrl keys and then click the required devices.
  2. Click Edit comment.

Troubleshooting Booting Errors

Sensors and TDUs have the same operating and statuses and error codes. These are described in DIMENSION 4 boot process overview

LED Error Codes and Timing Trees

In a timing tree, the upstream sensor distributes timing to the downstream sensors. If the upstream sensor is not working, the downstream sensors do not receive timing and the LEDs will flash green/orange (notice that this is not an LED error code). Therefore, when troubleshooting any booting errors, first examine the timing tree for any potential problems.

Rebooting Devices

To reboot sensors and TDUs:

  1. On the View sensor status tab, select the device that you want to reboot. To reboot multiple devices: press the Shift or Ctrl keys and then click the required devices.

  2. Click Reboot.

The status of the device first changes to Rebooting then, after the device is booted successfully, the status changes to Running.

When handling a large number of sensors, it is useful to group the sensors first. For example, to reboot sensors in a sensor group and then observe their status:

  1. Group the sensors by Group.

  2. Select the sensors in the Group, and then click Show selected.

  3. Click Reboot.

  4. Group the sensors by Status, and then click Expand all. The progress summary of only those sensors that you have rebooted is then displayed.

  5. When you have finished, click Show all.
