3-4 Setting Up the Repeater

Self-Test

When a repeater is powered on, it performs a self-test. If the test is successful,
all the LEDs flash yellow, then green, indicating that repeater is operating
properly and had no failures.
If the test is not successful, the LEDs do not flash, indicating some type of
failure. You can diagnose the failure by viewing the first three port LEDs on
the front panel. The following diagram shows the types of failures that can
occur and how you can identify them.
