After you turn on power to the firewall, the following sequence of events should occur:
1. When power is first applied, verify that the PWR LED is on.
2. After approximately 60 to 90 seconds, verify that:
a. The TEST LED is not lit.
b. The LAN port LEDs are lit for any local ports that are connected.

connected to a 10 Mbps device, the 10 Mbps LED will be green.
