1 Power-on indicator,
power button
The power-on indicator lights when the system
power is on. The power button controls the
power supply output to the system.
Warning: Turning off the power removes the
main power but keeps standby power
supplied to the Node. Because of this,
you must unplug the Node before
servicing unless you are replacing a
hot-swappable part (see Hot-
Swappable Parts on page 72).
Caution: Turning off the power without properly
shutting down the system may result in
loss of data (see Turning On and
Shutting Down the System on
page 21).
Note: To shut down the Node in the event of an
emergency, press and hold the power
button for 4 seconds. Warning: This may
result in data loss and may cause a delay
on next startup due to a blockpool verify
operation.

one of the buttons is pressed again.
