Chapter 2 Installing the System 27
After you have connected the power cables, you are ready to power on the system,
as described in the next section.
Powering On the System
Caution –
To avoid damage to internal circuits, do not connect or disconnect any
cable while the FRU associated with the cable is powered on.
1. Verify that the AC power cable of the system is connected to the correct AC outlet.
Caution – Do not disconnect the AC power cable from the outlet when working on
or in the system. This connection provides a grounding path that prevents damage
from electrostatic discharge.
2. At the bottom front and bottom back of the base cabinet, set the AC power
sequencer circuit breakers to the “On” position (
FIGURE 2-13
).
As soon as you connect AC power to the system, the Storage Service Processor
powers up.
The three power indicators on the front sequencer panel show the status of the front
power sequencer (
FIGURE 2-15
). The main AC power light emitting diode (LED)
illuminates when power is applied to the system. The LED for sequencer stage 1
illuminates next, followed immediately by the LED for sequencer stage 2.
