1 Diagnostic Indicators The diagnostic indicators light up to display error
statuses. For a description of possible statuses, see
Table 2 on page 26.
Note: The diagnostic indicators display error
statuses during system startup.
2 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.
Caution: Turning off the power without properly
shutting down the system may result in
loss of data (see Turning On and
Shutting Down the DXi4701 on
page 40).
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.
