Operation

Before you begin

Before powering on the enclosure system, make sure that all modules are firmly seated in their correct slots. Verify
that you have successfully completed the sequential "Installation Checklist" instructions in
you have completed these steps, you can access the management interfaces to complete the system setup.

Powering on/powering off

CAUTION: Do not operate the enclosure system until the ambient temperature is within the specified operating
range described in
make sure they have had time to adjust to the environmental conditions before they are used with production data
for I/O.
1. Power on the system by connecting the power cables from the PSU to the PDU. See
The System Power LED on the front panel should be lit green when the enclosure power is activated.
2. Power the system down by disconnecting the power cord from the power supply module.
When powering up, make sure to power up the enclosures and associated data host in the following order:
•
Expansion enclosures first.
This ensures that the DISCs in the drive enclosure have enough time to completely spin up before being
scanned by the controller modules within the controller enclosure.
While enclosures power up, their LEDs blink. After the LEDs stop blinking—if no LEDs on the front, back and
top of the enclosure are amber—the power-on sequence is complete, and no faults have been detected.

•
Controller enclosure next if an RBOD is used. Not applicable to server attached JBOD configuration.
Depending upon the number and type of DISCs in the system, it may take several minutes for the system to
become ready.
• Data host last (if powered down for maintenance purposes).
TIP: When powering off, you will reverse the order of steps used for powering on.
IMPORTANT: If main power is lost for any reason, upon restoration of power, the system will restart
automatically.
NOTE: See "LEDs" (page 66)
