Power Supply Requirements for the ServeRAID M5210 SAS/SATA Controller
All power is supplied to the controller 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:
1.
During a hard reset
2.
During a disk stress test
3.
While sitting idle at the DOS prompt
4.
During a disk stress test and deeply discharged Supercap pack.
The supply voltages are 12V ± 8 percent (from PCI edge connector only) and 3.3V ± - 9 percent (from PCI edge
connector only).
Table 6
lists the power supply for the controller for each of the three states at the different voltages.
3.2.5
Operating and Non-operating Conditions
The operating (thermal and atmospheric) conditions for the ServeRAID M5210 SAS/SATA controller are:
Relative humidity range is 20 percent to 80 percent noncondensing
Airflow must be at least 200 linear feet per minute (LFPM) to avoid operating the Intel IOP333 processor above the
maximum ambient temperature
Temperature range: +10 °C to +60 °C
The parameters for the non-operating (such as storage and transit) environment for the controller are:
Relative humidity range is 5 percent to 90 percent noncondensing
Temperature range: -30 °C to +80 °C
3.2.6
Safety Characteristics
The ServeRAID M5210 SAS/SATA controller meets or exceeds the requirements of UL flammability rating 94 V0. Each
bare board is also marked with the supplier name or trademark, type, and UL flammability rating. The board is
installed in a PCI Express bus slot, so all voltages are lower than the SELV 42.4 V limit.
