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 steps 1 through 11, you can access the management interfaces using your web-browser 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. With 2U enclosures, power on the system by connecting the power cables from the PCM to the PDU, and
moving the power switch on each PCM to the on position. See
The System Power LED on the 2U Ops panel should be lit green when the enclosure power is activated.
With 5U enclosures, power on the system by connecting the power cables from the PSUs to the PDU, and
moving the power switch on each PSU to the on position. See
The System Power LED on the 5U Ops panel should be lit green when the enclosure power is activated.
2. Power the system down by moving the power switch on the PCM or PSU to the off position.
When powering up, make sure to power up the enclosures and associated data host in the following order:
•
Drive enclosures first
This ensures that the disks 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 and back
of the enclosure are amber—the power-on sequence is complete, and no faults have been detected.
•
Controller enclosure next
Depending upon the number and type of disks 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.
