Alarms

DPS Expansion Module has visual and audible alarms that alert you to the status of the

system.

Visible alarms

The functional modules have associated status LEDs. The OPS panel shows a consolidated

status for all identified modules.

Audible alarms

DPS Expansion Module includes an audible alarm that indicates when a fault state is

present. The following conditions will activate the audible alarm:

•Fan fault

• Voltage out of range

• Over temperature

• Thermal overrun

• System fault

• Logical fault

• Power supply fault

• Removal of one power supply module

To mute an audible alarm, press the Alarm Mute button on the enclosure front panel. The

alarm will be muted automatically after two minutes if the mute switch is not manually

operated.

The alarm sounds continuously for critical error conditions such as when the enclosure

temperature has exceeded the upper limit, more than one fan fails, or the controller

temperature fails. You cannot mute these alarms.

LED State Description

Power On Steady Green Power applied to the enclosure.

System Fault Steady Amber Indicates a problem with a Power Supply or Cooling

Fan module. For specific fault LEDs per module, see

Power supply module LEDs on page 53 and Cooling fan

module LED on page 54.

Logical Fault Steady Amber Indicates failure of a disk drive in an array. The LED

will remain illuminated until the array is fault tolerant.

Disk drives not part of an array will not illuminate the

Logical Fault LED. See OPS panel LEDs on page 54.

Logical Fault LED will illuminate when a RAID

Controller fault occurs.

Box Identity Blinking Blue You can illuminate this LED from the DPS Expansion

Module interface to identify an enclosure.
