Replacing a Protected Station Faulty Radio
Replacing a faulty radio in a Protected Station can be achieved without disruption to traffic.
Assuming that the primary radio is active and the secondary radio is faulty and needs replacement:
1. Ensure the replacement radio has the same version of software installed as the primary radio. If
necessary, upgrade the software in the replacement radio.
2. Set the RF Interface MAC Address (see ‘Maintenance > Advanced’ on page 121). This MAC address is
present on chassis label.
3. Using SuperVisor > Maintenance > Advanced ‘Save Configuration to USB’ and ‘Restore Configuration
from USB’ operation, clone the primary radio’s configuration to the replacement radio.
4. Configure the replacement radio as the secondary radio and setup the other protection parameters
(see ‘Terminal > Operating Mode’ on page 76).
5. Using the Hardware Manual Lock switch, force the primary radio to active.
6. Carefully remove the faulty radio from the protection switch and install the replacement radio.
7. Power on the replacement radio and wait for it to become standby.
8. Set the Hardware Manual Lock switch to the Auto position.
Setting the Software Manual Lock
To make changes remotely to the Protected Station radios, the Software Manual Lock must be set to
prevent switch-over while making the changes (see ‘Lock Active’ on page 119). This procedure should be
followed when making changes that may interrupt traffic or cause a trigger a switch condition.
This procedure assumes that the Hardware Manual Lock is set to the Auto position, and there are no active
switching alarm conditions:
1. Login to the primary radio (left hand radio A by default).
2. Set the Software Manual Lock (Lock Active To) to Primary. The primary radio will become active i.e.
traffic will be switched to the primary radio.
3. Login to the secondary radio (right hand radio B by default).
4. Set the Software Manual Lock (Lock Active To) to Primary. This will prevent the secondary radio from
becoming active.
5. Make the changes to the secondary radio if required.
6. Set the secondary radio Software Manual Lock (Lock Active To) to Automatic.
7. Login to the primary radio (left hand radio A by default).
8. Set the Software Manual Lock (Lock Active To) to Secondary. This will prevent the primary radio from
becoming active.
Note: The Primary radio will become ‘Standby’ and the Secondary radio will become ‘Active’.
9. Make the changes to the primary radio if required.
10. Set the primary radio Software Manual Lock (Lock Active To) to Automatic.
