DIGITAL: Environment->Voltage Sensors

Description:
------------

The Voltage Sensors menu entry displays information about the voltage
sensors installed on the selected host.  The following fields are
displayed:

Index - Unique enumeration identifying each component.

Description - Description of the sensor.

Nominal Value - Indicates the nominal voltage rating.

Units - Units used by the other fields.  Possible values are:
	Unknown
	Other
	MillivoltsDC
	MilliVoltsAC
	VoltsDS
	VoltsAC
	MilliAmpsDC
	MilliAmpsAC
	AmpsDC
	AmpsAC
	Relative

Reading - Current state of voltage or current as detected by this
sensor.

Status - Status of the sensor.

Low Voltage - Default value for low voltage threshold.

High Voltage - Default value for high voltage threshold.

Need More Power voltage - Default value for Need More Power voltage
threshold.

Shut Now Voltage - Default value for Shutdown Now voltage threshold.

Troubleshooting:
----------------

"Warning:  no information returned for query" - There are two possible reasons
for this message.  First, the selected object does not have a Digital SNMP agent
running.  Second, the selected object's SNMP agent does not support these
particular MIB variables.

"Cannot get SNMP table.  No response arrived before timeout" - This message
means that the request was not returned from the selected object's SNMP agent.
Possibly the SNMP agent is not running or this system is inaccessible.
