3.3.4.6 Operating and Non-operating Conditions for the SAS 9261 RAID Controller
For the SAS 9261 RAID controllers, the operating (thermal and
atmospheric) conditions are:
• Relative humidity range is 5 percent to 90 percent noncondensing
(20 percent to 80 percent noncondensing for the RAID controllers)
• Airflow must be at least 200 linear feet per minute (LFPM) to avoid
operating the LSISAS2108 processor above the maximum
ambient temperature
• Temperature range: +10 ° C to +60 ° C without battery backup unit
• Temperature range: +10 °C to +44.5 °C with iBBU battery backup
The parameters for the non-operating (such as storage and transit)
environment for these controllers are:
• Temperature range: −30° C to +80° C without the battery backup unit
• Temperature range: 0° C to +45°C with the battery backup unit
3.3.5 Power Supply Requirements for SAS 9280 RAID Controllers
All power is supplied to the SAS 9280-8e and SAS 9280DE-8e RAID
controllers through the PCI Express 3.3V rails and the 12V rail. Onboard
switching regulator circuitry operating from the 3.3V rails and the 12V rail
provide the necessary voltages. The following states determine the
typical current consumption of the controller:
• State 1: During a hard reset
• State 2: During a disk stress test
• State 3: While sitting idle at the DOS prompt
The supply voltages are 12V ± 8 percent (from PCI edge connector only)
and 3.3V ± 9 percent (from PCI edge connector only). Table 3. 13 lists
the power supply for the controller for each of the three states at the
different voltages.
