Impediment RS-1600-X24 User Manual page 219

You can also use the Mute button on the X24 Ops Panel to turn off the alarm when it sounds.
The alarm sounds for temperature or voltage conditions (events). Warning events are generated when
the temperature or voltage enters the warning range. Shutdown events are generated when the
temperature or voltage enters the shutdown range. After reaching the shutdown range, the X24
Subsystem will not function. You must resolve the problem and restart the X24 Subsystem. If the problem
is not resolved, it will shut down again.
Alarm conditions trigger an event message that displays in the Disk Array Administrator software window
and in the event log. See
page 164.
A change to this setting on either SM module is automatically updated on the other SM module.
Table 7–3shows the temperature and voltage thresholds for each alarm and what to do to resolve the
problem.
Table 7–3 .Alarm thresholds
Alarm threshold
X24 internal temperature
• Warning: 0°C to 4°C and
66°C to 70°C
• Shutdown: <0°C and >70°C
X24 CPU temperature
• Warning: 0°C to 4°C and
91°C to 100°C
• Shutdown: <0°C and >100°C
VCC voltage
• Warning: 5 V -10% to -8% and +8%
to +10%
• Shutdown: 5 V <-10% and >+10%

What to do when the alarm sounds
• Check the Disk Array Administrator software to confirm
what the alarm means. See
Log", on page
• Check the ambient temperature and lower it, if needed.
Ambient temperature should be less than 45°C.
• Check that the X24 Subsystem has good airflow
clearance. The X24 Subsystem requires airflow
clearance on all sides, except the bottom and top.
• Check that the internal fans are running. The fans are in
the Power Managers.
• Same as above.
• Check the Disk Array Administrator software to confirm
what the alarm means. See
Log", on page
• If it is a warning alarm, let the X24 Subsystem continue
to operate.
• If it is a shutdown alarm, see which SM module is
showing the alarm. If only one SM module shows the
alarm, replace that SM module. If it is both, you must
troubleshoot the Power Supply/Cooling modules.
