Intelibs, Inc. Proprietary and Confidential Page 27 27 Following is one example of LMT operation which sets the upper limit of MRU chassis’ temperature. Step 1 • Click the box which is on the right side of “TMPUPR”. A number in the box represents current upper limit of chassis’ temperature and change the value. And then enter the key. Step 2 • Enter desired TMPUPR value by clicking arrow button or entering number. Then press “Set” button. • Then the bottom of the window shows result of command. • Press 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 MRU chassis’ temperature. If the box is GREEN, operating status is in normal condition. If the box is RED, “TMPUPR” alarm occurred and remains.
