4 Release latch Press to release the sled from the enclosure.
5Power-on indicator/
power button
The power-on indicator lights when the
sled power is on. The power-on indicator
lights amber when the system critical event
occurs.
NOTE: The power-on indicator lights amber
according to critical system error log (SEL)
assertion. If the SEL is full or a deassertion
event occurred while sensor monitoring is
paused (e.g. fan monitoring is paused during
system power off), the power-on indicator
turns amber. To turn off an amber LED and
reset the power-on indicator to normal
condition (solid green), either perform a
BMC cold reset or reseat the sled in the
server enclosure.
The power button turns the compute
sled on.
NOTES:
•When powering on the sled, the video
monitor can take from several seconds
to over 2 minutes to display an image,
depending on the amount of memory
installed in the system.
•On ACPI-compliant operating systems,
turning off the sled using the power
button causes the sled to perform a
graceful shutdown before power to the
sled is turned off.
•To force an ungraceful shutdown, press
and hold the power button for five
seconds.
