22 Installation ELS100-24TXM
•Memory
Memory tests on the CPU RAM are performed after the ser ial port
test. No results are displayed on the console.
After these two tests are performed, the operational software of the switch
is loaded. A series of more extensive diagnostic tests are then conducted
during which the Test LED remains lit. The results of the tests are
displayed on the terminal. If all tests pass, the Test LED turns off. When
all tests are complete, the system is functional and the user interface i s
ready to receive commands at the console.
