Starting a system that is not managed by an HMC or an SDMC
You can use the power button or the Advanced System Management Interface (ASMI) to start a system
that is not managed by a Hardware Management Console (HMC) or an IBM Systems Director
Management Console (SDMC).
To start a system that is not managed by a HMC or SDMC, follow these steps:
1. Open the front rack door, if necessary.
2. Before you press the power button on the control panel, ensure that power is connected to the system
unit as follows:
v All system power cables are connected to a power source.
v The power LED, as shown in the following figure, is slowly flashing.
v The top of the display, as shown in the following figure, shows 01 V=F.
3. Press the power button (A), as shown in the following figure, on the control panel.
v A: Power-on button
v B: Power LED
– A constant light indicates full system power to the unit.
– A flashing light indicates standby power to the unit.
Note: There is approximately a 30-second transition period from the time the power-on button is
pressed to when the power LED goes from flashing to solid. During the transition period, the LED
might flash faster.
