TABLE 2-3.
Powering On the Server
Do not use this power-on procedure if you have just added any new internal option
or external storage device, or if you have removed a storage device without
replacing it. To power on the system under those circumstances, you must initiate a
reconfiguration boot. For those instructions, see
“Initiating a Reconfiguration Boot”
on page 24.
Caution – Never move the system when the system power is on. Movement can
cause catastrophic disk drive failure. Always power off the system before moving it.
1. Establish a connection to the system console.
If you are powering on the system for the first time, connect a terminal to the serial
management port. For more information on establishing a connection, refer to the
Netra 240 Server Installation Guide (817-2698).
2. Connect the server to a power source.
Once connected, the server automatically goes into Standby power mode.
