5.3 VIEWING POWER UP DIAGNOSTIC TESTS

The MicroMMAC-T runs from BootPROM comprehensive booting and diagnostic tests of the device whenever it has been started or reset. You can view a chronicle of the tests and any error condition messages they produce by connecting your terminal to the COM 2 port of the MicroMMAC-T. BootPROM loads the test image into Flash at the completion of the test, which lasts approximately two minutes.

NOTE: The LCD displays the following message whenever the POWER

UP DIAGNOSTIC test is running: “Cabletron Test in Progress.” See Section 5.2 for information about LCDs.

The testing process generates information and displays it on your terminal. The only time you can issue commands controlling the display of the information is when an error condition has been discovered.

Figure 5-2 shows the opening test information sequence of the POWER UP DIAGNOSTIC screen depicting an error condition message with response options that are discussed below.
