Remote Outlet Switching/Monitoring Configuration
The DPC is equipped with individually switchable outlets. Total current for each group of outlets is available on the Sensors page and on the Control page.
The unit will list all available outlets under “DPC Configuration” on the Control page. Each outlet has five fields associated with it:
- Name: A friendly name to easily identify what is plugged into the outlet, for example “Mail Server.”
- URL: Enter a URL associated with the equipment plugged into the outlet. This URL will appear as a clickable link at the top of the Control Page next to the outlet status information.
- Power−On Delay: Delay from the time the “On – Delayed” action is executed until the outlet will turn on.
- Power−Off Delay: Delay from the time the “Off – Delayed” action is executed until the outlet will turn off.
- Reboot Delay: Delay from the time the “Reboot” action is executed and all selected outlets have turned off until the outlet will turn back on.
The Max Group Amps (MGA) setting is a protective feature designed to help eliminate downtime due to overloading of a power strip. The unit will not allow any more outlets in the same group to turn on once the MGA threshold has been reached. For example, if MGA is set at 10A, there are 3 outlets enabled in Group A and the total draw for Group A is 9A, the unit will allow a fourth outlet to turn on. However, if after enabling the fourth outlet, the current draw were to rise to 11A, no more outlets in Group
A would be allowed to turn on. If the total draw drops below 10A, another outlet will be allowed to turn on.
NOTE: DPC will not shut off any outlet automatically, even if the MGA has been exceeded. It is still possible to overload the strip if the load on any outlet is increased after the outlet is turned on. It is advisable to set an alarm on each group based on the MGA as an additional warning of potential problems.
Remote Outlet Switching Control
There are six possible actions for any given outlet, available from the
“Action” drop down box on the Control page:
- On – Immediate: Turns on all checked outlets immediately.
- On – Delayed: Turns on all checked outlets subject to the “Power On” delays entered at the bottom of the Control page.
- Off – Immediate: Turns off all checked outlets immediately.
- Off – Delayed: Turns off all checked outlets subject to the “Power Off” delays entered at the bottom of the Control page.
- Reboot: Turns off all checked outlets immediately and turns them back on subject to the “Reboot” delays entered at the bottom of the Control page.
- Cancel Actions: Cancels any actions currently in progress on the selected outlets.
To perform an action, select the check box next to the outlets needing attention, select an action from the drop down box and click the “Execute” button. A dialog box will appear asking for confirmation of the selected actions. Click OK to allow the action to proceed or click Cancel to make changes.
Internal Sensors
All internal sensors are measured every 5 seconds. External sensors are measured every 10 to 30 seconds depending on the # of devices connected. Sensor data collected by the Hoffman Smart unit gives useful trend analysis data. While all values are not absolute in relation to a known unit, trend analysis of the data allows users to view changes in data value over time. Analysis of the change in value of the data can lead the user to useful conclusions about what is happening in the monitored environment.
- Volts – Measures instantaneous RMS voltage.
- Volts (Peak) – Reports the highest reported voltage since the last time the data was updated, typically every 5 seconds.
- Amps – Measures instantaneous RMS current.
- Amps (Peak) – Reports the highest reported current since the last time the data on the screen was updated, typically every 5 seconds.
- Real Power – Average of instantaneous voltage and current over the last 1.5 seconds.
- Apparent Power – The product of instantaneous RMS Voltage and RMS Current. This is the value used by circuit breakers.
- Power Factor – The ratio of Real Power to Apparent Power.
- Amps Group – Reports the group SUM of individual receptacle readings.
Connecting Optional RJ Remote Sensors
Plug and Play Remote Sensors may be attached to the unit and in some cases
splitters may be required to add additional sensors.
Each sensor has a unique address and is automatically discovered and added to
the webpage. Note: the display order of the sensors on the web page is
determined by the internal ID of each sensor, a customizable friendly name is
available for each on the
Display page.
The supplied wires can be extended or shortened using Cat 3 wire and RJ12
connectors. Note: the sensor wire has six conductors, wiring must be
straight−through: reverse polarity will temporarily disable all sensors until
corrected. The sensors use a serial communication and are subject to network
signaling constraints dependent on shielding, environmental noise, and length
of wire.
Typical installations should allow runs of up to 600 feet of sensor wire.
Optional RJ Remote Sensors
- DST Temperature
- DSTA Temperature / Airflow
- DSTAH Temperature / Airflow / Humidity
Custom lengths available upon request at 763.422.2661 or dataservice@hoffmanonline.com
Graphing and Displaying Data
All data collected by the unit can be graphed. The Log page allows the user to
select graphed content and sampling rate, selected items will be displayed on
LCD (on units where it is present, or optional Remote Display). The amount of
data and sample rate determine the graph time span. This period is calculated
and displayed on the Log page. When the onboard memory fills up,old data will
be deleted, making room for new data. All settings are stored in case of a
power loss or reboot. A sample rate of 30 seconds or longer is recommended to
allow the unit to gather all sensor data before graphing. Sampling rates of 60
to 120 seconds should provide ample resolution for most situations.
Setting Alarms
For all data collected by the unit, the user can set high and low limits. When
these limits are exceeded the user has the option of sending an email, SNMP
trap, activate the audible alarm (on units where it is present), or any
combination of the three. The SNMP traps can be sent to 4 IP addresses. Some
analysis of each unit is recommended before setting alarm limits. Once each
unit has been operating in the environment under normal, steady state
conditions for several hours, alarm set points may be chosen. By allowing the
unit to come to steady state before setting alarm set−points, the user may
make more informed decisions about the normal variation in conditions and
choose alarm set points that will inform when conditions are truly changing
without triggering numerous false alarms. Aside from using historical graphs
to make alarm set−point decisions, the user may choose to download raw log
data from the logs page to see specific historical data records and use this
data to help set useful alarm set−points. Note:
Changes in settings are processed less frequently and depending on the number
of attached devices may take several minutes to respond. Rapidly resetting
alarm values may not provide desired results. Allow up to 2 minutes after
making a setting change before modifying. Test alarms can be sent for each
measured value via the Alarms page.
Optional DRD Remote Display
This small module can be mounted in an accessible spot inside or outside the
rack or cabinet. A LCD display scrolls values of items selected on the Logs
page. The connection to the unit is made with a 10’ handset type 4−conductor
cable. The buzzer can be activated for alarm states to identify problems. An
alarm reset is located next to the display to silence the buzzer when the
problem is located. The LED indicator stays on in alarm state even after the
buzzer has been silenced.
Optional IP−Enabled Web Camera
The unit has been designed to allow up to 4 IP Network Cameras to interface
with the webpage. To enable this feature the camera must be set to allow
anonymous access. The unit Configuration page allows you to add the IP address
of the camera and specify the model. This live image will appear on the
Sensors page and will update with the webpage. Clicking on the picture itself
will take you to the IP address of the camera. Each device currently supports
up to 4 cameras simultaneously.
Supported Cameras: Axis 205/206, D−Link DCS−900, D−Link DCS−950/G, D−Link
DCS−5300/G
Other Formats
- PDA Displays data in a small screen format for a PDA.
- WAP Wireless Application Protocol, displays text values for wireless clients such as mobile phones and some PDAs.
- XML Extensible Markup Language, displays values in XML format.
- MIB Management Information Base, downloads the MIB to be used for SNMP applications.
Accounts, Passwords and Security
- The unit is accessible via a standard, unencrypted HTTP connection as well as an encrypted HTTPS (SSL) connection. The user may opt to enable access via HTTP, HTTPS, or both HTTP and HTTPS. It is not possible to disable the web interface completely.
- The unit has a View−Only account, a Control Access account, and an Administrator account. When activated the Administrator account limits access to any web pages with configuration settings. When left blank no username or password is required to adjust the configuration. When activated, the View−Only account requires a username and password to view sensor data. The
- Control Access account allows access to the Control page, allowing configuration of attached switch−able power distribution units. The Administrator account must be password protected to activate the View−Only and Control Access accounts. The user may choose any name for the
- Administrator, Control Access, and View−Only accounts consisting of alphanumeric characters, spaces, and underscores, except for “root” and “admin”. These account names are disabled for security reasons and cannot be re−enabled.
WARNING! Record your password. Loss of password will require the unit serial number and contact of customer service to be recovered.
Setting Time and Date
- The unit comes preconfigured with the IP addresses of two military NTP servers and set to the Central Time Zone (−500 GMT).
- Should a local time server be preferred, enter its IP address into the box and click the “Save Changes” button. Should the user need to revert back to the military time servers, simply clearing the time server addresses and clicking “Save Changes” will set the time servers back to the defaults.
- The unit attempts to contact the timeservers while booting up. If a timeserver is unavailable, all log time stamps will present time as the number of seconds since the unit was powered up. Note: that the time and date are not adjusted for daylight savings time. Setting the time zone offset forward and backward an hour will cause a gap or overwriting of logs, respectively.
Telnet
When using Telnet to connect to the unit, the Administrator username and
password from the Configuration page will be required.
If the Administrator user is not configured, the Telnet server will be
enabled, but logins will be impossible. The Telnet server can be disabled on
the Configuration page. Available Telnet commands can be found by using the
command “help”. The following are some commonly used Telnet commands:
Airflowset – Resets the internal airflow sensor such that the current flow is
measured as ‘20’.
- Exit – Terminates the Telnet connection.
- Reboot – Reboots the controller board remotely. Power distribution is not affected.
- Report – Displays a report of all connected sensors and their current values.
- Time – Displays the current date and time according to the unit if the unit has contacted an NTP server.
- System info – Displays general information about the unit, including: Unit type, Software version and MAC address.
SNMP
The unit is accessible via SNMP and can be configured to send out SNMP traps
to a maximum of 4 IP addresses when alarm conditions are met. The community
string defaults to “public,” but is user−customizable on the Configuration
page. The MIB is downloadable via a link at the top of the web interface. The
MIB is walk−able via any SNMP browser, but will have to be imported before
doing so. The SNMP service can be disabled via the Configuration page. A test
SNMP trap can be sent from the Configuration page.
E−Mail
- The unit is capable of sending e−mail to a maximum of 5 e−mail addresses when alarm conditions are met. E−mail settings are on the Configuration page. An SMTP server, a “From” address and a “To” address are required to send email alerts. Some e−mail servers are password protected and will require a POP server, username and password for validation. In most cases, the username does not have to match the “From” address, but does need to be a valid user on the POP server. Microsoft Exchange servers will have to be set to allow SMTP relay from the IP address of the unit. A local network administrator will have to change this setting.
- A test email can be sent from the Configuration page.
Daily Affirmation
Daily Affirmation allows the users to choose a frequency with which the unit
will forward a full status report to their e−mail. This status report can come
hourly, every 2, 4, 8, or 12 hours, or once daily (24 hours). This feature
allows you to know that everything is still running, and gives you an update
on all attached devices as well. Set−up of this feature is on the
Configuration page under ”Status Reports”.
Owner Contact Information
Owner contact information can be entered on the Configuration page and will
display at the bottom of the web interface.
