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
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
"Environmental requirements" (page
have had time to adjust to the environmental conditions before they are used with production data for I/O.
•
Power ON the enclosure by connecting the power cables from the PSU to the PDU. See
System Power LED on the front panel should be lit green when the enclosure power is activated.
•
Power OFF the system by disconnecting the power cord from the power supply module.
When powering ON, make sure to power up the enclosures and associated data host in the following order:
1. Expansion enclosures (Exos E 4U106) first
This ensures that the disks in the expansion enclosures have enough time to completely spin up before being
scanned by the Controller modules within the server enclosure (Exos AP 4U100).
While enclosures are getting powered ON, 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.

"Overview of front panel LEDs"
b. See
"Overview of rear panel LEDs" (page 33)
c. See
"Overview of top LEDs" (page 38)
2. 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.
Depending upon system configuration, when power is applied to the 4U100 enclosure, the Controller modules will
either boot to standby or move to full operation. To transit from standby to operation, you can use "Reset" button or
use IPMI. For more information consult with your Integration partner.
3. Data host last (if powered OFF for maintenance purposes).
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.
