BN Disconnected from TCS

BN Alarm

If a BN becomes disconnected from TCS, an alarm should be present in TCS. To verify, follow these steps:

  1. Log into TCS.

  2. Click Alarms on the navigation pane.

  3. Check if there are any open alarms by searching for the BN in question.

Further information may be found via the Performance menu:

  1. Click the Device menu in the navigation pane.

  2. Find the row that corresponds to the BN in question.

  3. Click the BN hostname to open the device specific page.

  4. Check the Information card to confirm the network entities it is part of (Market, Site, Cell).

  5. Click Performance in the navigation pane.

  6. Toggle the switch in the upper left-hand corner of the screen to Compare KPIs.

  7. Click Customize and select the appropriate KPIs that may indicate a reason for the disconnect. These can include CPU Utilization, Input Voltage, etc.


    The BN may reboot if the voltage drops below 40V.

  8. Choose the time period to graph the data. Use the zoom tool (mouse drag in the graph) as needed.

BN Unable to Resolve TCS Address

The BN will not show up in TCS if it cannot resolve the TCS address. To verify, follow these steps:

  1. Log into the BN web UI by connecting to the Mgmt port on the BN with a laptop and typing in to a browser window (ensure the laptop is on the same subnet).

  2. After logging into the web UI, click Setup in the navigation pane.

  3. Check the DNS Servers listed under Network Services. Verify the FQDNs and IP addresses are correct.

  4. Click Save Config.

If the DNS Server information is correct:

  • Check the configured servers are responding via ping, etc.

  • Verify that other web sites load properly. If other web sites load properly, contact Tarana Technical Support for further help.
