XLIGHTS(4) OpenBSD Programmer's Manual (MacPPC) XLIGHTS(4)NAMExlights - Xserve G4 and G5 front panel LEDs
SYNOPSIS
xlights* at macobio?
DESCRIPTION
The xlights driver provides support for the on-board i2s virtual sound
device that drives the front panel LEDs of Apple G4 and G5 Xserve
machines.
The lights provide an indication of system load and health. System load
is indicated by three dots travelling in a ring around the sixteen LEDs
found on the front panel. When the system is lightly loaded these dots
travel quickly and slow down as system load increases. System health is
indicated by the absence of the dots which means a hung machine or one
that is in ddb(4).
