8.2.17.1 Troubleshooting the RSN
Using the same technique above, place the RSN you want to test in the RCT Cradle.
If you see the heartbeat LED is lit, then you know that the RSNs is working. If the RSN is
still not working (receiving or transmitting), then the trouble is with another component in
the IMS.
Using the illustration above, you can see the status of the LEDs on the RCT Cradle. Using
the RSN Troubleshooting Solutions table below, if an LED is not lit, look at the possible
causes in the Not Illuminated column. For a possible solution to why the LED is not
illuminated, look in the Description and Resolution columns.
