Onboard Indicators
GLAN1/GLAN2 LEDs
Each of the Ethernet ports (located beside the VGA port) has a yellow and
a green LED. See the tables below for the functions associated with these
LEDs.
On each Gb LAN port, the yellow LED indicates activity while the
other LED may be green, orange or off to indicate the speed of the connec-
tion (as specified in the tables below).

Debug LEDs
Two sets of surface-mounted debug LEDs are located beside the LAN2 port
and are each composed of four individual LEDs (D1 through D8) , which are
used to provide POST code information. See the diagrams below for read-
ing 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).

Reading the Debug LEDs:
W hen on, each of the eight separate
LEDs represent the value of the
number shown beside it in the
diagram. Add up the numerical values
of each illuminated LED in the D5-D8
row to get the high digit (left) and
those in the D1-D4 row to get the low
(right) digit of the corresponding
hexidecimal PO ST code.
Example:
The example on the left indicates a
hexidecimal PO ST code of C6. This is
determined in the following manner:
D1-D4 (right digit): 4 + 2 = 6
D5-D8 (left digit): 8 + 4 = 12
(decimal 12 = hexidecimal C)
