Testing the Enclosure Connections
Use this procedure to power on the newly installed system.
1. Press the power switches at the back of each drive enclosure to the On ( –) position.
This ensures that the disks in the drive enclosures have enough time to completely
spin up before being scanned by the RAID modules in the controller enclosure.
Depending on your configuration, it can take several minutes for the system to
power up.
While enclosures power up, their LEDs blink. After the LEDs stop blinking, if no
LEDs on the front and back of the enclosure are amber, the power-on sequence is
complete and no faults have been detected.
For a description of LED behavior and status, see “Hardware Components and
LEDs” on page 13.
2. Press the power switches at the back of the controller enclosure to the On ( –)
position.
If the enclosure’s power-on sequence succeeds as described in Step 1, the system is
ready to use.
