How-To-Troubleshooting Procedures

Check a TRAK_ALARM

Trak 9100 Known Alarms

Check Trak 9100 events/alarms in UEM.

When TRAK9100 fails, a field tech would have to check the status LEDs to verify if the issue is a hardware failure.  FSU cards, Power Supplies, and GPS antennas are known to fail.

Determine NTP Servers

Use this table to determine what would be the NTP server address for different network devices we use:

Note that the selected name of the server needs to be converted into IP Address prior setting the value to device.

• Network Time Protocol (NTP) provides a clock synchronization mechanism to the RDMs and other NTP clients at the site. In a high-availability configuration, the NTP clients must use the TRAK 9100 Simulcast Site Reference (SSR), at the prime site, as the primary time source; and an ntp02.zoneNdevice at a zone core as the secondary time source. The RDMs at the site also act as an NTP time source. The base radios use RDM A as the primary NTP time source, and use RDM B as the secondary NTP time source.
• NTP provides a clock synchronization mechanism to the NTP clients at the site. All NTP clients use the TRAK 9100 SSR at the prime site (ntp01.site#.zone#) as the primary time source and the Virtual Management Server (ntp02.zone#) at the zone core as the secondary time source. This configuration applies even for subsites equipped with a TRAK SSR.
• NTP source “ntp02.zone#” resides on a Generic Application Server if the system deployment/release does not include Virtual Management Servers.

Shutting OFF an RF Site/Bringing an RF site back into Wide Trunking

A Customer may call us requesting for temporary disabling of an RF site.

A typical example is Putting an RF site OFF for maintenance due to antenna replacement.

IMPORTANT: Only a specific list of people should have the ability to request a Site-OFF. Please refer to customer specific CSP or any similar document for permission validation

Shutting OFF an RF Site Procedure:

 1. From the left pane, under “Network Database”, select “Site” and find the site name:

2. Look for the “Repeater Site” type of object. Locate the appropriate site, Right-click on it and

select “Issue Command”: 

3. In the Command Window, select “Site” on the left, then “Site Off” and “Apply”:

Result: The site will go in Site-OFF Mode, which will stop any transmission.

Look for a positive message in the Status Bar.

Site equipments are still powered-on and accessible via network management applications. Site is OFF, no transmitter keyed and not accessible for subscriber traffic.

You can see the Site-OFF state in UEM and Zonewatch.

Restore the service when instructed to by proceeding with “Requesting a Wide-Trunking state from UEM”.

Bringing an RF site back into Wide Trunking:

1. Follow the steps 1 and 2 from the "Shutting OFF an RF Site"  procedure.

2. In the Command Window, select “Site” on the left, then “Wide Trunking” and “Apply”:

Result: The site will go in Wide trunking Mode, which will restore trunking operation including an Active Control Channel.

Look for a positive message in the Status Bar

 Site is Wide Trunking, a control channel is on-air and the site is accessible for subscriber traffic.
