2 Powering up and powering down
the enclosure
IMPORTANT:
Before installing this product, read the

Powering up

Observe the following guidelines before powering up the enclosure:
• Install all components of the enclosure.
• Install hard drives in the enclosure so the connected host controller can identify and configure
them at powerup.
• Always power up the enclosure first, and then the server. This ensures that the servers, during
their discovery, see the enclosure as an operational device. If you do not power up the enclosure
before powering up the servers, you will need to power down the servers, ensure that the
enclosure is powered up, and then power back up the servers.
To power up the enclosure:
1. Complete server hardware installation and cabling. See the server documentation.
2.
Connect the SAS cables and power cords to the enclosure. See
3.
Press and hold the Power On/Standby button. Wait and observe the system power LED and fan
modules. When the enclosure powers up, the system power LED illuminates solid green and the
fans spin to a high speed, and then spin down to a low speed.
4.
Power up the servers. See the server documentation.

Powering down

CAUTION:
Be sure that the server is the first unit to be powered down and the last to be powered back up. Taking
this precaution ensures that the system does not erroneously mark the drives as failed when the server is
powered up.
IMPORTANT:
If installing a hot-plug device, it is not necessary to power down the enclosure.
To power down the enclosure:
1.
Power down any attached servers. See the server documentation.
2.
Press the Power On/Standby button on the enclosure. Wait for the system power LED to change
from green to amber.
3. Disconnect the power cords.
The system is now without power.
