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
Table 3 (page 36) . Once 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 “Environmental requirements” (page 94) . If the drive modules have been recently installed, 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 Figure 61 (page 69) .
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.

See “Overview of top panel LEDs” (page 31) and figures/tables for top panel FRUs.
• 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 72) for details pertaining to front panel LEDs and related fault conditions.
