4.3 The 3-Slot Desktop Chassis
4.3.1 Alarm Reset, Last Gasp, and Temperature Gauge
The 3-Slot Desktop Chassis ships with one or two AC or DC power supply
modules, depending on the model. Fans are included in all models.
Alarm Reset Button
When one power supply module malfunctions, an audible alarm sounds
indicating the loss of the power supply. The alarm can be silenced by pressing
the Alarm Reset Button, located next to the power connector on the power supply
module. If this occurs the unit needs to be returned to Black Box for repair.
Last Gasp Alarm
The 3-Slot Desktop Chassis includes the Last Gasp trap feature, “Remote
Chassis Down”, which sends a Trap when the following occurs:
• Both power supply modules malfunction
• Both power supply modules are powered down
• When the AC line fails
Temperature Gauge
The 6-Slot Rackmount/Desktop Chassis includes a temperature monitoring
gauge with a heat sensor on the backplane of the chassis. Users define a
threshold for chassis temperature via SNMP. If the chassis’ temperature rises
above the specified level, the SNMP agent sends a trap (configured in iView²) to
the administrator. There is also an LED indicator on the SNMP Management
Module for chassis temperature.
