Turn on the power switch.
The Power LED lights green (see Figure 1-1). If it does not, check to
make sure that the power cable is plugged in correctly and that the
power source is good.

screen. If you want to display the results of the tests after the switch has
already been turned on, turn the power switch off and then back on.
The switch performs two basic types of tests at power-up. During this
time, the Test LED (see Figure 1-1) lights steady green. These tests are:

Serial port
The serial console port test is the first test performed. If the switch
fails this test, no further tests are performed, and the console displays
no information.
