Powering on disk enclosures
IMPORTANT:
Always power up disk enclosures before controllers and servers. This ensures that the servers, during
their discovery, see the enclosure as an operational device. If you do not power up the disk enclosures
before powering up the controllers and servers, you will need to power down the servers, ensure that
the disk enclosures are powered up, and then power back up the servers.
1. Apply power to each UPS.
2. Apply power to the disk enclosures by pressing and holding the power on/standby button on
the rear of 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.
CAUTION:
If power is applied to the server before the disk enclosures complete their startup routine, the
server might not properly discover the storage.
4. Power on (or restart) the server with access to the disk enclosures, start the operating system, and
log on as administrator.
CAUTION:
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.
5. Verify that each component is operating properly.
