Exclusive Web \fdministration Features
You can perform the same administr\Bative configuration from the web administration in\Bterface that is available from the user 
interface. The web administration in\Bterface contains the following additional features not available from the user interface.
Using \fdvanced Directory Features
\fdvanced usage of th\Be directory is available only from the web administration in\Bterface. On the Directory tab, the List \fll button 
retrieves the current directory data. You can import and export entries to and from the local directory using the Import and 
Export buttons; you can export entries from the corporate directory. Clear \fll deletes all entries in the local di\Brectory. Search 
enables you to locate a specific entry in the directory.
When importing and exporting directory entries from the web administration in\Bterface, use a text editor that supports UTF-
8 encoding to view or edit the data. D\Bouble-byte characters are not supported in directory entries imported using the web 
administration interface.
Saving and Restoring a System Configuration
You can save and restore a system configuration onl\By from the web administration in\Bterface. 
NOTE
System restore is not supported with the FireFox browser or other browsers based on Mozilla code.
The System Save feature creates a text file that contains command line interface commands to restore a saved configuration. The 
saved configuration inc\Bludes all the preferences that can be se\Bt through the command li\Bne interface, except the command lin\Be 
interface password and the password for the default SNMP \Buser. You can edit the file \Bmanually to customize the configuration. \B
The System Restore feature restores a system configuration usi\Bng the saved configuration file\B. For more information about 
editing commands in\B the configuration fil\Be and saving and restoring a system configuration usi\Bng the command line\B interface, 
refer to LifeSize Passport \futomation Command Line Interface.
NOTE
Configuration preferences and options v\Bary across the system software releases. Restoring a system configuration usi\Bng a 
file saved from a different model or software release may produce unexpected results. L\b recommends that you restore a 
configuration that was\B saved from the same system or the same system model and software release.
To save a system configuration from the web administration in\Bterface, follow these steps:
1.  In the web administration in\Bterface, navigate to P\fefe\fe\bces : System : System Reset. If you wish to save system 
passwords in the file, select Save passwords. Passwords saved with this option a\Bre not encrypted.
2.  Click System Save.
3.  In the Download file dialog \Bbox, click Yes.
4.  When prompted, choose a location\B in which to save the configuration fi\Ble and then click S\Bave.
To restore the system configuration from the web administration in\Bterface, follow these steps:
1.  Ensure that a saved configuration file\B exists before performing a restore.
2.  If you chose not to save passwords when you saved the configuration \Bfile, passwords appear in the fil\Be as tokens 
surrounded by ### characters and FIX: precedes the command \Bin the configuration \Bfile, for example:
 FIX: set admin pas\Psword ###Password###
If you wish to replace these tokens with passwords before using the file to restore a system, delete FIX: and replace 
###token### with the passw\Bord. If you do not edit these \Blines, error 09 (invalid command) app\Bears in the command\B 
output when you restore the system; the FIX: lines \Bare ignored; and values previously set for the passwords remain 
unchanged.

3.  Close all calls co\Bnnected to the system. If calls are connected when you perform a restore, a dialog appears\B prompting 
you to continue or cance\Bl the restore. If you continue, the system restore process terminates the calls.
4.  In the web administration in\Bterface, navigate to P\fefe\fe\bces : System : System Reset.
5.  Click System Restore.
6.  If an error dialog appears, examine the errors. You may wish to copy and paste the errors into a text editing program for 
analysis and troubleshooting. Errors due to the presence of FIX: lin\Bes identify command\Bs with token passwords that were 
not manually edited. Other errors may indicate a problem with restoring a specified preference or restoring the entire 
configuration. For a description of the error codes that can ap\Bpear, see “Standard Return Codes” in the LifeSize Passport 
\futomation Command Line Interface manual.
7.  Click Continue. The system reboots and a dialog\B appears indicating\B that the restore was successful.
Copying Screen Text to the Clipboard
The web administration in\Bterface supports copying data from most screens to the operating system clipboard. This feature 
facilitates troubleshooting by enabling you to paste configuration information into an email or text editing application\B. If a 
screen supports this feature, a Copy button appears in the l\Bower right corner of the screen. Click the Copy button to copy the 
data on the screen to the clipboard.
Downloading Call History
You can download call history as a comma separ\Bated value file (.csv\B file extension) from the Diagnostics page in the \Bweb 
administration interface. Click Call History and then click Download Call History. When prompted, choose a location\B to save the 
file. The call history file contains the s\Bame output that is pr\Boduced when you execute the following command in the\B command 
line interface:
 
  stat\fs call histor\b -f -?
 
Downloading call his\Btory from the web administration in\Bterface retrieves a maximum of 26\B records. You can retrieve up to  
1 000 records using the comman\Bd line interface. Restoring a system to default settings, or executing the set system clean -C 
command from the command line\B interface, deletes call history from the system. For more information, refer to LifeSize Passport 
\futomation Command Line Interface manual.
Upgrading System Software
You can upgrade your system software and manually ins\Btall a license key only from the web administration in\Bterface. For more 
information, refer to “Upgrading your System Software” on page 54.

Near End Video Quality
Before you place a call, examine the near \Bend video image of\B the camera. If the image flickers, colors appear un\Bbalanced, or the 
image appears too dark, you may need to adjust the room lighting or cam\Bera brightness and whitebalance.
Placing a Call
You can place a vid\Beo or voice call with your VCS system in the following ways:
• Select a stored number from the REDI\fL list o\Bn the main screen or from the directory.
• Manually dial a num\Bber using the Video Call or Voice Call buttons on the main scr\Been.
You can place a cal\Bl with the IP addresses. This enables systems inside a corporate network without access to a gateway to call 
other systems in the network using system IP addresses.
NOTE
When microphone howling occurs during the Video or Voice call, the microphone will be shu\Bt off automatically and the i\Bcon 
for announcing that th\Be microphone is shut off w\Bill appear on the l\Bower right-hand corner of the screen automatically. 
Placing a Call from the REDI\fL List
The REDI\fL list on th\Be main screen stores up to 15 recently dialed numb\Bers. \f scroll bar appears wh\Ben more than five entries are 
available for selection. The oldest entry in the list is automatically removed when the system receives a call after the maximum 
number of entries has been reached.
The last call placed\B always appears at the top of the list. The entry includes the name\B of the system called and an i\Bcon that 
indicates whether the call \Bwas a voice  or video  call. The entry’s number (and band\Bwidth if the entry is a video call)\B 
appears below the list when the e\Bntry is selected. If the system receives a call, but does not answer it, the call appe\Bars in the 
REDI\fL list as a mis\Bsed call. The  symbol appears ne\Bxt to the name in the en\Btry. Select the entry to display the date and time 
of the missed call \Bbelow the REDI\fL list.
To place a call from the REDI\fL list, \Buse the arrow keys on the remote control to select an entry and press OK.
To change the bandwi\Bdth for a video call on\B the REDI\fL list bef\Bore placing the call, select Video Call on the main scr\Been, press
