Specifications
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.
NOTE: Depending on your web browser, multiple web accesses from the same machine are often treated as one user.
Temperature Status
The Temperature Status graph displays a blinking error whenever temperature exceeds the low or high
threshold. The PT22 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 PT22 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 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.
