Operations Switched PDU
Installation and Operations Manual
Active Users:
Displays the number of active user sessions accessing the firmware. These sessions include serial,
TELNET, SSH, and Web sessions. Active Users also shows sessions that an unauthorized user may be attempting to
access. The number shown in Active Users changes instantly as the number of active user sessions change. A total of
4 concurrent web user sessions are allowed (HTTP or HTTPS).
NOTE:
Depending on your web browser, multiple web accesses from the same machine are often treated as one user.
Total Power Consumption:
Displays the total system power (in Watts) being distributed by the current PDU
configuration.
Line Status
The Line Status graph displays a blinking warning (yellow), whenever the total input load on an infeed exceeds the
present user set threshold. If an overload occurs, a blinking error condition (red) is displayed. The unit continues to
display these yellow and red states until the condition changes or the problem has been resolved.
The default input feed high load threshold is 80% of the input feed maximum load capacity.
NOTE:
The input feed high threshold is user-defined. You must configure this threshold value on the SNMP/Thresholds page or the
Command Line Interface (CLI).
Temperature Status
The Temperature Status graph displays a blinking error whenever temperature exceeds the low or high threshold. The
PDU will continue to display this state until the condition changes or the problem has been resolved.
For the temperature sensor, the default range of low/high temperature values is 5º-45º C (41º-115º F).
Up to four sets of dual temperature/humidity sensors can be displayed in this graph for a total of eight possible
temperature sensor graphs. A thin blue line separates each set based on the tower or environmental monitor.
NOTE:
The temperature threshold values are user-defined. You must configure these threshold values on the SNMP/Thresholds page or the
Command Line Interface (CLI).
Humidity Status
The Humidity Status graph displays a blinking error whenever humidity exceeds the low or high threshold. The PDU
will continue to display this state until the condition changes or the problem has been resolved.
For the humidity sensor, the default range of low/high humidity percentage is 0-100% (relative humidity).
Up to four sets of dual temperature/humidity sensors can be displayed in this graph for a total of eight possible
humidity sensor graphs. A thin blue line separates each set based on the tower or environmental monitor.
NOTE:
The humidity threshold values are user-defined. You must configure these threshold values on the SNMP/Thresholds page or the
Command Line Interface (CLI).
Field Descriptions
The following fields and icons are viewed left to right for Line Status, Temperature Status, and Humidity Status:
Icon:
Provides quick viewing of current operational state: Information
, Warning
and Critical
.
ID:
Device input feed or sensor identifier.
Name:
Descriptive, user-defined name for each input infeed or sensor.
Load, Temp, Humidity:
Current state of the reported input load (in amps), current temperature, or current
percentage of relative humidity.
Low Limit:
Displays the user-defined low limit of the load, temperature, or humidity graph. These values depend on
the sensor limited and cannot be set by the user. For example, a 0ºC low limit would be displayed as
for a
temperature sensor graph in Celsius.
Sensor Graph and Level Indicator:
The horizontal sensor graph shows current operating conditions in color-coded
segments. See the section below, “Sensor Graph Color Coding” for details. The level indicator
appears across the
graph to indicate the relative position of the current data value with respect to the minimum (low limit) and maximum
(high limit) values displayed at the left and right of the graph.
