Configuring Redundancy Triggers
An alarm may be enabled (active) but not enabled for redundancy; for example, the over-
temperature alarm may be active, but unless it has been enabled for redundancy, the
APEX
will not failover
to the backup due to an over-temperature fault.
Using the
Redundancy Triggers
window, you must individually select which alarms are
required for redundancy in your configuration scheme. When these triggers are enabled,
the APEX will failover to the standby unit whenever any triggering conditions take place.
You can configure the following parameters in the
Redundancy Trigger Configuration
section of the Chassis Redundancy Configuration window:
Parameter
Description
•
GigE 1 and 2 Link Loss
•
GigE 3 and 4 Link Loss
•
Enet 1 Link Loss
•
Enet 2 Link Loss
You can configure the APEX to failover due to link faults. By default, a
link loss condition on an enabled GigE interface will cause a failover
because it is a critical fault.
If
transport stream redundancy
is in use (where a secondary stream is
received on a different interface), you may configure the APEX1000 to
failover
only
after the pair of GigE links are lost. You may also define
whether ENET1 and ENET2 link loss will cause a failover.
Notes:
1. GigE link loss is only selectable when GigE interfaces are enabled.
2. ENET2 link loss should not be enabled if directly connected to the
secondary APEX by means of a crossover cable.
Temperature Fault
The APEX will failover due to over-temperature detected.
QAM Module Fault
The APEX will failover due to QAM module fault detected.
•
Critical
indicates clock, PLL, data sync, communication, configuration,
RF output level, unsupported HW faults, invalid code versions, code
downloading, or code download failed.
QAM RF Port Fault
The APEX will failover due to QAM RF port fault detected.
•
Critical
indicates clock, PLL, or data synchronization problem.
•
QRM code download in progress, QRM code download failed, and
unsupported QRM.
QAM Channel Fault
The APEX will failover due to QAM channel fault detected.
•
Critical
indicates data fault.
To configure any the parameters available in the Redundancy Triggers screen:
1.
Place a checkmark in the corresponding checkbox to certify that failover will occur
upon detection of that specific fault.
2.
