4.2 Example: Setting the Temperature Upper Limit
Following is one example of LMT operation which sets the upper limit of RU chassis’ temperature.
• At “Repeater Browser” window, click the DAS system to be managed, then the selected DAS
system’s control window will pop up.
Step 1
• Click the temperature upper limit box which is on the right side of “TMPUPR”. A number in the
box represents current upper limit of chassis’ temperature.
• Select TMPUPR value by clicking up/down button or enter temperature upper limit. Then click
“Set” button.
Step 2
• The result of operation displays at the bottom of the window.
Intelibs, Inc Proprietary and Confidential Page 36

• Click close button on the upper right corner of the window to exit the command window.
The small color box on the left side of “TMPUPR” represents current status of upper limit of RU
chassis’ temperature. If the box is GREEN, operating status is in normal condition. If the box is
RED, “TMPUPR” alarm occurred and remains.
4.3 Web interface
Master Unit provides comprehensive management of the Intelibs optical DAS systems via Web GUI.
Master Unit provides following functions for Web clients:
• Hierarchical view of the DAS systems
• Alarms histories
• Current Alarms
• SNMP agent settings
• Site and location information settings
• Web user settings
• Capture and restore the configuration of the DAS systems
• Parameter settings of the DAS systems
The web GUI is divided into two parts, a menu panel and a Parameter view panel. The menu panel is on
the left side of main window, and the other side is the parameter view panel as shown in Figure 4-3.

• Open Web browser such as Internet Explorer or Chrome.
Step 1
• Enter Master Unit’s IP address that is assigned for Web interface. Usually the IP address is global
IP or private IP if web client is on the same network where Master Unit is.
• Enter Login ID and Password. (Please contact Intelibs for login ID and password)
Step 2
The web interface provides two level user access, privileged or not. Privileged users can retrieve
and change the advanced parameters that control the DAS system. For example, “TMPUPR”
parameter is an advanced parameter that requires privileged user login.
• If ID/PWD matches, Web interface goes to Home page.
