Starting the System with an HMC Attached
Power on the system only after all of the following steps are completed:
v All I/O drawer cables are connected
v
Base system cables are connected
v All PCI cables to supported subsystems are connected
v
The hardware management console (HMC) is connected (if required)
v Power is connected to the system
After the required cables are installed and the power cables are connected, the HMC user interface
provides a power-on function to turn on the power to the system. If a system operator panel is available,
the power-on button on the operator panel can be pushed to initialize the system but the preferred method
is to use the HMC if you are booting logical partitions. Progress indicators, also referred to as
checkpoints ,
are visible on the operator panel display (if available) as the system power is turned on. The power LED
on the base system stops blinking and stays on, indicating the system power is on.
The base system and I/O subsystems are powered on through the system power control network (SPCN).
When power is applied, the power LEDs on the base system go from blinking to continuous, and the
power LEDs on the I/O subsystem(s) come on and stay on, which indicates that power levels are
satisfactory in the subsystems.
After the system is powered on, all logical partitions will be in a standby or powered on state. Each logical
partition must then be booted through the HMC. The state of all logical partitions that have been booted
will be
running .
