Powering on and powering off the blade
server
Important information
If the server is connected to external storage devices, make sure the server is the first device to
power off and then the last device to power on. This restriction prevents the server from mistakenly
identifying the external storage devices as faulty devices.
Powering on the blade server
Guidelines
If the blade server is successfully powered on, the system power LED turns steady green. For more
information about the position of the LEDs, see "Appendix A Server specifications."
As a best practice for the internal components to operate correctly, do not perform the power on
action immediately after powering off the server. Wait for over 30 seconds for HDD drives to stop
rotation and electronic components to be powered off completely.
Prerequisites
Before you power on the server, you must complete the following tasks:
•
Install the server and internal components correctly.
•
Connect the server to a power source.
Procedure
Powering on the blade server together with the enclosure
If you want to power on the server together with the enclosure, configure the power-on delay for slots
first. After configuration, power on the enclosure, and the blade server is powered on automatically
based on previous settings. No extra action is required.
For more information about the power-on delay for slots, see the OM online help.
