Powering On the Server Locally
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 62
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.
Caution – Before you power on the system, ensure that the system doors and all
panels are properly installed.

To Power On the Server Locally
1. Turn on power to any external peripherals and storage devices.
Read the documentation supplied with the device for specific instructions.
2. Establish a connection to the system console.
If you are powering on the system for the first time, connect a device to the serial
management port using one of the methods described in Chapter 2. Otherwise, use
one of the methods for connecting to the system console, also described in Chapter 2.
3. Connect the AC power cords.
Note – As soon as the AC power cords are connected to the system, the ALOM
system controller boots and displays its power-on self-test (POST) messages. Though
the system power is still off, the ALOM system controller is up and running, and
monitoring the system. Regardless of system power state, as long as the power cords
are connected and providing standby power, the ALOM system controller is on and
monitoring the system.
