Each of the Ethernet ports (located be-
side the VGA port) has a yellow and a
green LED. See the table on the right for

LED1/LED2 (Debug LEDs)
The two surface-mounted debug LEDs (LED1 and LED2) are each com-
posed of four individual LEDs, which are used to provide POST code infor-
mation. See the diagrams below for reading the debug LEDs and refer to
Appendix B for a complete list of POST codes (a partial listing of the most
common codes are given below). The description below for reading the
LEDs is when viewed from the top/front side of the chassis.
