3.6 Initialization
After the device is powered on, it begins the Power-On Self-Test. A series of tests run automatically
to ensure the device functions properly. During this time, its LED indicators will respond in the
following order:
1. The PWR LED indicator lights on all the time. The SYS LED and the LED indicators of all the ports
keep off.
2. After about one minute, the SYS LED and LED indicators of all the ports will flash momentarily and
then turn off.
3. Several seconds later, the SYS LED indicator will flash, which represents a successful initialization.
