step 2 connect the other end of the power cable to a grounded ac outlet.
after the switch powers on, it begins the power-on self-test (post), a series of tests that run automatically to ensure that the switch functions properly.
post lasts approximately 1 minute. when post is complete, only the syst and stat leds remain green. the mastr led is also green on a single switch or on a stack master switch.
the syst led turns amber if the post fails. if the post fails, see chapter 4, “troubleshooting,” to determine a course of action.
