Powering on the disk enclosure

After disk enclosures are physically installed and cabled, power on all devices and verify that they
are operating properly.
Power on best practices
Observe the following best practices before powering on the disk enclosure for the first time:
Complete the server, controller, or controller enclosure installation. For more information, see the
server, controller, or controller enclosure user documents.
Install the disk enclosures.
Install disk drives in the disk enclosures so that the connected host controller can identify and
configure them at power on.
Connect the SAS cables and power cords to the enclosure.
Powering on disk enclosures
IMPORTANT:
Always power on disk enclosures before controller enclosures and servers. This ensures that servers,
during the discovery process, identify the enclosures and installed disk drives as operational devices.
1.
Apply power to each uninterruptible power supply (UPS). For more information, see the UPS
documentation.
2.
Apply power to the disk enclosures. Press and hold the power on/standby button on the disk
enclosures until the system power LED illuminates solid green.
The LED on the power on/standby button changes from amber to solid green, indicating that the
disk enclosure has transitioned from a standby state to fully powered.
3.
Wait a few minutes for the disk enclosures to complete their startup routines.
IMPORTANT:
If power is applied to the server before disk enclosures complete their startup routine, the server
might not properly discover the storage and may erroneously mark the drives as failed when the
server is powered on.
4.
Apply power to the controller enclosure (if included in the configuration). For more information,
see the controller enclosure documentation.
5.
Power on (or restart) the server with access to the disk enclosures, start the operating system, and
log on as administrator. For more information, see the server documentation.
IMPORTANT:
When you power on the server, the monitor might display a "New Hardware Found" message.
Cancel out of this window to prevent the installation of unsupported software.
6.
Verify that each component is operating properly.
