Web
Opening a Web Connection
This section explains the Web interface in detail. From the Web, you can
monitor and control the UPS in which the card is installed. You can also
configure many settings of the card.
NOTE: To specify that the card communicates at either 10Mbit or
100Mbit, instead of it trying to auto-negotiate, you must use the Service
Terminal.
You access the Web Interface of the OpenComms Web Card by opening
a direct web browser. The card utilizes functionality of Microsoft Internet
Explorer 5.0 or higher. Whenever possible, you should use the latest
copy of IE.
1. Open your web browser software.
2. Enter the IP address or hostname of the card in the address line of
your browser.
The first page you will see every time you open a new Web connection to
the card is the Power Flow folder in the monitor tab. After your browser
connects, you will see a screen very similar to below:
You will notice that information on the Web page is grouped in Tabs and
Folders. The card organizes similar information together in folders, and
similar functions in tabs.
Tabs: Across the top of the screen are four tabs, monitor, control, configure, and support. As the tab names suggest, different information is presented and different operations are available to you under each tab.
Folders: Within each tab, you will see a different list of folders on the left
pane of your screen. Here, display, control, and configuration information
grouped logically. If, for example you click the Input folder under the
monitor tab, you will see only information about the UPS' input power.
A rigorous explanation of the information in the tabs and folders is not
necessary, as you will quickly sort out why things are where they are. So,
the discussion that will follow for the rest of the Web section touches on
the important functionality delivered in certain areas.
Connected Device Information
Clicking between the monitor, contol, configure, and support tabs gives
you access to folder lists on the bottom of the left pane. Although the
folder list changes, depending on the tab selected, the top portion of the
left pane remains constant. In the top or the left pane, connected device
information and connected UPS status is always presented.
The IP address of the card and the Liebert UPS model type is presented
under Connected Device:. In this example, the InOpenComms Web Card
is installed in a UPStation GXT 700VA UPS and has been assigned the
IP address, 126.4.20.92.
The current operating state of the UPS is presented under Connected
Device Status: along with the most serious UPS alarm, if one if present.
For our example above, the UPS is operating normally with the load protected.
Security
By opening a connection to the OpenComms Web Card, you are able to
do three things. You can Monitor, Configure and Control the UPS.
The card allows any user with access to the network segment on which it
resides to monitor the UPS. This means anyone on the segment can
view the entire contents of the monitor and support tabs.
The card restricts access to the folders in the control and configure tabs.
When a user clicks on a folder, they are prompted for a User Name and
Password.
The factory default User Name is "Liebert" and the Password is "Liebert".
Because this is a well-known username and password, you should
change it as soon as possible. You should change the username and
password as soon as possible. If you have not made this change from
the Service Terminal, you can do so from the Web.
Monitor Tab
When you select the monitor tab, you are presented with Connected
Device: and Connected Device Status: on the top of the left pane. The
Folder list is at the bottom of the pane under Device Information:.
The first page you will see every time you open a new Web connection to
the card is the Power Flow folder in the monitor tab. After your browser
connects, you will see a screen very similar to below:
From the monitor Tab, you are able to view the parametric data of the
UPS.
The Power Flow folder provides a graphical representation of the current
state of the UPS along with useful information about Input, Output, and
Battery voltages as well as Battery runtime information.
The Alarm folder provides a list or any present UPS alarms.
Clicking on the Battery, Output, Input, Bypass (not supported in PowerSure Interactive UPSs), or Internals folder replaces the summary data
presented on the graphical power flow pane with a tabular view of the
complete list of data points reported by the UPS. Clicking on the Input
folder presents a screen similar to:
In the tabular view data, like Input voltage, that changes over time is
grouped as a Parameter. Values, which are known to the UPS, like Nominal input frequency, are reported in Information. Finally, condition
parameters, like Utility failed, are together in a table labeled, Condition.
The list of data in each of these sections and folders varies across UPS
product lines and sizes and will change depending on the UPS in which
you have installed the card.
Control Tab
When you select the control tab, you are presented with Connected
Device: and Connected Device Status: on the top of the left pane. The
Folder list is at the bottom of the pane under Control Operations:.
As detailed in the Web Security section, a Username and Password protect the folders in the control tab.
From the control tab you can silense alarms remotely, turn the UPS' output ON or OFF or Reboot the UPS.
Each folder represents a different control behavior and this list will vary
across UPS product lines and sizes.
Configure Tab
When you select the configure tab, you are presented with Connected
Device: and Connected Device Status: on the top of the left pane. The
Folder list is at the bottom of the pane under Configuration Categories:.
As detailed in the Web Security section, a Username and Password protect the folders in the configure tab.
When you click on a folder under Configuration Categories: you will be
able to edit network and device settings, including SNMP community lists.
The folder list is shown below:
Device Info
Clicking on the Device Info folder allows you to edit the Name, Contact,
Location, and Description fields.
Factory Defaults
Clicking on the Factory Defaults folder allows you to reset the card to the
factory settings.
Network
Clicking on the Network folder allows you to reset the card to the factory
settings.
SNMP
Clicking on the SNMP folder allows you to enable authentication traps.
Clicking on the Access or Traps folder allows you to configure the devices
you want to have access to the card via SNMP and devices you want to
receive traps from the card. The Access folder is shown below:
As you are adding communities, you need to consider access rights.
Notice above, that 126.4.1.100 has write access when the device passes
the correct Community String of MyCommunity. This means that this network device has both read and write access to the card, whereas
126.4.1.200 has only the ability to read information when providing the
correct Community String. Devices with write access can control the UPS
and reconfigure settings of the card. In order for a device you have added
to the Access folder to also receive notification from the card via SNMP
Traps for UPS alarms and condition changed, you also need to add the
device toe the Traps folder.
Users
Clicking on the Users folder allows you to edit the Username or Password
that must both be entered correctly to control the UPS or change configuration settings of the card from the Web.
The factory default User Name is Liebert and the Password is Liebert.
Because this is a well-known username and password, you should
change it as soon as possible. You can also change the Username or
Password from the Web.
From the Web, you need to know the current Username of Password to
make a change.
Web
Clicking on the Web folder allows you to modify the Web browser refresh
rate. Due to the static nature of the Web, the card instructs your Web
browser to refresh many areas of the card's web page at a specific interval.
Configure Tab - Making and Saving Configurations
Similar to configuring the card using the Service Terminal, every time you
make a configuration change, the card will have “save and reboot” for that
change to take effect. As you navigate between the card's control web
pages, you will notice that configuration screens include Edit and Save
buttons and a Reinitialization folder. As an example, the screen shot
below shows the edit fields available under the configure tab when you
select the SNMP folder:
The Edit button allows configuration and parameter changes.
Once the Edit button is selected, a Save button will appear in its place.
The Save button can be used at any time during the (re)configuration process. Once the Save button is selected, the user will be prompted to reinitialize the card, so
that the new settings
will
take
effect. During this
time, the card is
unavailable on the
network. When this
process
begins,
your web browser
may be instructed
to open a new page.
Configure Tab - After Reinitialization
Once card reinitialization is selected and confirmed, the card is unavailable on the network. As the card reboots, it first begins communicating
on the network and it will begin communicating with the UPS in which it is
installed. The card will present to you some helpful information during the
period of time that it is restarting.
Support Tab
When you select the support tab, you are presented with Connected
Device: and Connected Device Status: on the top of the left pane. A single device list is at the bottom of the pane under Support:.
The support tab displays the Name, Location, and Description fields as
well as relevant contact information for Liebert Technical Applications
support.
SNMP
The OpenComms Web Card utilizes a SNMPv1 agent and is MIB-II compliant. The card supports the open standard UPS MIB RFC1628, with
additional functionality and support through the Liebert Global Products
MIB. A copy of the Liebert Global Products MIB is included on the CD
included with your purchase. Likewise, the latest version of Libert Global
Products MIB can be obtained at www.liebert.com.
Appendices
MultiLink Support
The most frequently asked question about configuring MultiLink to monitor a SNMP device, like the OpenComms Web Card, across the network
is, what community string do I use?
NOTE: Use the community string LiebertEM for MultiLink.
Configuring for MultiLink support from the Service Terminal
From the Main Menu, select option "3" for SNMP Communications Menu.
In order for MultiLink to monitor the card, the network address information
of the machine on which MultiLink is installed needs to be added to both
the Display/Modify Communities and the Display/Modify Trap Communities.
As an example, you have installed MultiLink on a PC and you will monitor,
across the network, the OpenComms Web Card you are now installing.
Your PC has the IP address of 126.4.1.1.
Select option "2" from the SNMP Communications Menu and add
126.4.1.1 with the community string Liebert EM.
Select option "3" from the SNMP Communications Menu and add
126.4.1.1 with the community string Liebert EM.
If you have made changes, you need to press "ESC" to return to the Main
Menu and then press "x" to exit and save changes.
Adding to both the Communities list and the Trap Communities list is necessary for MultiLink to work properly.
Configuring for MultiLink support from the Web
Open a web connection to the OpenComms Web Card. Click on the Configure tab. In order for MultiLink to monitor the card, the network address
information of the machine on which MultiLink is installed needs to be
added to both the Access and Traps selection folders as stated in the
above examples.
