Loading Firmware
In Case of Difficulty
If the firmware did not load successfully, LED patterns on the front panel can help you
isolate the problem.
• If the following LED pattern is present, an acceptable firmware file name was not found
on the disk. (The desired format for firmware filenames is 8753ES.07._yz, where
yz = the latest firmware revision number.) Check that the firmware disk used was for
the 8753ES.
• If any of the following LED patterns are present, the firmware disk may be defective.
• If any other LED pattern is present, the CPU board is defective.
