Note: The power-control button has effect only if local power control is enabled for
the DPI blade. Local power control is enabled and disabled through the
management-module Web interface.
Power-on LED: This green LED indicates the power status of the DPI blade in the
following manner:
v Flashing rapidly: The service processor (BMC) on the DPI blade is initializing
v Flashing slowly: The DPI blade has power but is not turned on.
v Lit continuously: The DPI blade has power and is turned on.
Turning on the DPI blade
The DPI blade has two power domains: PD1 and PD2. Power domain 1 (PD1)
occurs automatically when the DPI blade is connected to the BladeCenter unit. This
enables the BMC to communicate with the management module and control the
DPI blade.
Power domain 2 (PD2) occurs when power is applied to the entire DPI blade
through the host blade server.
Depending on the binding state of the DPI blade, you can turn on the DPI blade
using the power button on the front of the DPI blade, through the advanced
management module interface, or through the ASM. The preferable way to turn on
the DPI blade is through the ASM.
Notes:
1. Wait until the power-on LED on the DPI blade flashes slowly before you turn on
2. For you to power-on the DPI blade through the ASM, the DPI blade must be
Turning off the DPI blade
Note: When you turn off the DPI blade, it is still connected to power through the
BladeCenter unit. The DPI blade can respond to requests from the management
module, such as a remote request to turn on the DPI blade. To remove all power
from the DPI blade, you must remove it from the BladeCenter unit.
The DPI blade can be turned off in any of the following ways:
v You can press the power button on the DPI blade (behind the control panel door)
v The management module can turn off the DPI blade:

on the DPI blade (see "Control panel buttons and LEDs" on page 4).
– The preferable way to turn off the DPI blade is through the ASM. If you are
removing or changing the DPI blade in any way, you must unbind the DPI
blade by using the ASM before you proceed. See Chapter 2, "Setup
information and instructions," on page 7 for more information about the
binding process.
– If there are critical voltage or temperature errors, the management module will
automatically turn off the DPI blade
