System Status Power LED, Beeps | HP D315 specification

Chapter 4 System Support

The systems covered in this guide utilize the following specialized functions built into the LPC47B367 I/O Controller:

♦Power/HD LED status indicators – The I/O controller provides color and blink control for the front panel LEDs used for indicating system events as listed below. Indications valid for both D315 and d325 unless otherwise indicated.

System Status	Power LED	HD LED	Beeps
S0: System on (normal operation)	Steady green	Green w/HD activity	None
S1: Suspend	Blinks green @ 0.5 Hz	Off	None
S3: Suspend to RAM	Blinks green @ 0.5 Hz	Off	None
S4: Suspend to disk	Off	Off	None
S5: Soft off	Off	Off	None
Processor not seated	Steady red	Off	None
ROM flashing	[1]	Off	None
No memory installed	Blinks red @ 2 Hz	Off	None
Power supply crowbar activated (D315	Blinks red @ 0.5 Hz	Off	None
only)
CPU thermal shutdown	D315 [2], d325 [3]
Memory error (d325 only)	See note [4]	Off	5
Video error (d325 only)	See note [5]	Off	6
System board failure (d325 only)	See note [6]	Off	7
Invalid ROM checksum (d325 only)	See note [7]	Off	8
System off	Off	Off	None

NOTES:

[1]Red during flash, then blinks green @ 1 Hz when user can reboot.

[2]Repetitive sequence of 2 red blinks @ 1 Hz, followed by 2-second pause.

[3]Repetitive sequence of four red blinks @ 1 Hz followed by 2-second pause

[4]Repetitive sequence of five red blinks @ 1 Hz followed by 2-second pause.

[5]Repetitive sequence of six red blinks @ 1 Hz followed by 2-second pause.

[6]Repetitive sequence of seven red blinks @ 1 Hz followed by 2-second pause.

[7]Repetitive sequence of eight red blinks @ 1 Hz followed by 2-second pause.

♦I/O security – The parallel, serial, and diskette interfaces may be disabled individually by software and the LPC47B367’s disabling register locked. If the disabling register is locked, a system reset through a cold boot is required to gain access to the disabling (Device Disable) register.

♦Legacy/ACPI power button mode control – The LPC47B367 receives the pulse signal from the system’s power button and produces the PS On signal according to the mode (legacy or ACPI) selected. Refer to chapter 7 for more information regarding power management.
