TrangoLINK Apex™ 18 User Manual Rev. 1.0 Section: Appendix A - Command Set Summary Page 89
All set commands on the Active unit are also executed on
the Standby unit to keep the states synchronized. The 2
units have separate IP Settings/Mgmt Channel and can
be upgraded independent of each other.
In the event of system failure or link loss the Active
transfers control to the Standby, only if the Standby is
healthy. If the active unit is powered down or if the
redundancy cable is unplugged then Standby will assume
the role of the Active.
Once the Standby unit takes over, the failed active unit is
powered off and the data ports disabled.
The failed unit is not rebooted and can be used to
diagnose the problem.
Appropriate traps are sent in the case of Active failover,
Standby detection and Standby taking over as Active.
The “status modem” command on the Active unit will
display the current health of the Standby unit.
Standby Lock: 1
Standby ODU 1
Standby RSSI: -41 dBm
The standby is considered healthy when the lock indicator
status is 1.
