Chassis Install Instructions (734751-001, March 2014)

4 Powering up
After disk enclosures are physically installed and cabled, power up all devices and verify that they
are operating properly.
Before powering on
Observe the following best practices before powering on the 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.
Power on procedures
1. Apply power to each power supply module.
2. Once power is applied to the power supplies, the enclosure starts running.
The power on LED turns solid green.
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. Apply power to the controller enclosure (if included in the configuration).
5. 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.
6. Verify that each component is operating properly.
