CUSL-L
CUSL-L System Panel Connectors
19) System Power LED Lead (3-1 pin PLED)
This 3-1 pin connector connects the system power LED, which lights when the
system is powered on and blinks when it is in sleep mode.
20) Keyboard Lock Switch Lead (2-pin KLCK)
A 2-pin connector to the case-mounted key switch for keyboard locking.
21) System Warning Speaker Connector (4-pin SPEAKER)
This 4-pin connector connects to the case-mounted speaker. Two sources
(LINE_OUT and SPEAKER) will allow you to hear system beeps and warn-
ings. Only SPEAKER will allow you to hear system beeps before the integrated
audio has been properly initialized.
22) IDE Activity LED (2-pin IDELED)
This connector supplies power to the cabinet's IDE activity LED. Read and
write activity by devices connected to the Primary or Secondary IDE connectors
will cause the LED to light up.
23) System Message LED Lead (2-pin MLED)
This indicates whether a message has been received from a fax/modem. The
LED will remain lit when there is no signal and blink when there is data re-
ceived. This function requires an ACPI OS and driver support.
24) System Management Interrupt Lead (2-pin SMI)
This allows the user to manually place the system into a suspend mode or "Green"
mode, where system activity is decreased to save electricity and expand the life
of certain components when the system is not in use. This 2-pin connector con-
nects to the case-mounted suspend switch.
25) ATX Power Switch Lead (2-pin PWR)
The system power is controlled by a momentary switch connected to this lead.
Pressing the button once will switch the system between ON and SOFT OFF.
Pushing the switch while in the ON mode for more than 4 seconds will turn the
system off. The system power LED shows the status of the system's power.
26) Reset Switch Lead (RESET)
Pressing the reset button restarts the computer if a system freeze-up occurs.
