Operation Alarm Red Red Red Red
Operational Alarm
An operational alarm is indicated by all 4 LEDs periodically flashing red (no green flashes). This alarm can indicate the radio has
detected an error which may not be recoverable by the user. Depending on why the operational alarm has occurred, the event log
can be referred to, which may help diagnose why operation alarm is active.
HSC Mode Alarm
Each QB within a Hot Standby arrangement should have HSC Mode enabled by the user. When HSC mode is enabled, the QB
will attempt to negotiate and pair with an alternate QB. If HSC mode is disabled, a QB will ignore any HSC mode negotiation
messages it receives.
QB (within a QH)
Alarm Type
Pwr / Tx Sync / NoRx COM 1 RxD / TxD COM 2 RxD / TxD
Pairing Alarm Green Green
Description of Alarm When a QB in HSC mode attempts to negotiate with the alternate base, and no response
is received, a pairing alarm will be displayed (flashing all red, then, green as shown above)
Probable Causes (1) There is a mismatch in the configuration between Base A and Base B. Check that
HSC mode, IP address, SUBNET mask, shared IP and VLAN parameters are suitably
configured. For further information on configuration of Hot Standby radios refer to
Part G of this user manual.
(2) There is a problem with the cable connection in the hot standby arrangement.
Check cables are properly inserted into their correct locations.
Refer to “Step 2 - Interface Connections” in the ‘QH Quick Start Guide’ section.

QHHSC Change-Over Pending Timer Alarm
After a change-over occurs within a hot standby arrangement, the QHHSC will run a 60 second timer. If a new alarm is detected
on the online QB during this 60 seconds, the QHHSC will prevent the change-over and indicate a ‘Pending Timer’ alarm. Once
the timer reaches 0, the change-over will proceed. The pending timer helps prevent a high number of change-overs occurring in
a short period of time.
A pending timer alarm is indicated on the QHHSC with a flashing green LED on the corresponding radio LED (Radio A/B).
