Status monitoring and display

The major status monitoring capabilities of these enclosures include:

• Displaying the enclosure status on the enclosure icons

• Displaying the blower, power supply, EMU, drive, and I/O module status on the element LEDs

• Detecting the installation of blowers, power supplies, drives, or I/O modules

• Detecting the removal of blowers, power supplies, drives, or I/O module

• Sensing enclosure internal temperatures

• Sensing power supply voltage, current, and total power

• Sensing ambient temperature

NOTE:

The ambient temperature is the temperature at the enclosure air intake, or the room temperature.
