Starting the System

This section discusses the various ways to start the system.
Starting the System without a Hardware Management Console (HMC)
Attached
To start a system that does not use an HMC, do the following:
1. On a Model 6C3, open the front rack door.
On a Model 6E3, open the bezel door.
2. Ensure that the power is connected to the system unit.
Before you press the power-on button on the operator panel, observe the following:
v The power LED is slowly blinking.
v An OK prompt is visible in the operator panel display.
3. Press the power-on button on the operator panel.
After pressing the power-on button on the operator panel, observe the following:
a. The power LED begins to blink visibly faster.
b. The system cooling fans are activated after approximately 30 seconds and begin to accelerate to
operating speed.
c. There is approximately a 30-second transition period between the time the power button is pressed
and the power LED remains on solid (no longer blinking). The power LED stays on solid and
progress indicators, also referred to as checkpoints, are visible on the operator panel display.

Starting the System with an HMC Attached

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. The power-on button on the operator
panel can be pushed to initialize the system but the preferred method is to use the HMC. Progress
indicators, also referred to as checkpoints, are visible on the operator panel display as the system power
is turned on. The power LED on the system stops blinking and stays on, indicating the system power is
on.
The system unit is powered on through an internal system power control network (SPCN). When power is
applied, the power LEDs on the system unit go from blinking to continuous. This indicates that the system
power levels are satisfactory.
