notes will cause malfunctions or failures of the server.
„
Make sure to power off the server before connecting or disconnecting cables between the

„
Use the forced shutdown feature (pressing the POWER switch for 4 seconds or longer) in
emergency state only (e.g., when an OS command does not shutdown the server, the
POWER switch does not turn off the server, or resetting does not work). Do not use this
feature in usual power-off operation.

Observe the following:
– When you have just turned off the AC power of the server, wait at least 30 seconds
before turning it back on.
– When you have turned on the AC power of the server, wait at least 30 seconds before
