MOUNTING AND WIRING GUIDE
|
Status
The green “STATUS” LED is located on the cover. On the main board, it is also the
green “SYSOK” LED next to the “HBEAT” LED—both are found near the Ethernet
connector housing. The status LED should remain lit whenever the controller is
powered
, or else be blinking during the boot sequence. If the status LED
does not
light
while power is applied, contact System Engineering for technical support.
Heartbeat
The yellow heartbeat “HBEAT” LED is located on the cover, as well as on the main
board next to the “SYSOK” Status LED. The heartbeat LED blinks about once per
second. If the heartbeat LED stays
on constantly
,
does not light
, or blinks
very
fast
(more than once per second), contact System Engineering for technical support.
Debug
The yellow “DEBUG” LED is located on the main board near the Ethernet connector
housing, and remains lit whenever the controller has been rebooted with the “serial
mode select” jumper in the “serial shell” position (see
on page 14). This
indicates that the DB-9
port is operating in serial shell mode.
USB
Three yellow LEDs “LD1”, “LD2”, and “LD3” are located together on the upper left
area on the main board, in the option slot 2 area. These LEDs indicate USB hub and
port (1 and 2) activity, respectively. These LEDs will not be easily visible if an option
card is installed in the upper (Slot 2) option slot.
Ethernet Ports
Two LEDs for each of the two LAN ports are provided on the back of the metal LAN
connector housing, and operate as follows.
The left-side
green
“activity” LED indicates activity on that port as follows:
•
Off
— No Ethernet link is made
•
On
— Ethernet link is present, but no activity on the LAN
•
Blinking
— Ethernet link is present with data activity on the LAN.
The right-side
yellow
“speed” LED indicates Ethernet connection speed, as either:
•
Off
— “Fast Ethernet” / “Ethernet” (100 Mbps /10Mbps).
•
On
— “Gigabit Ethernet” speed (1000 Mbps).
