IBM MegaRAID 8480 manual Electrical Characteristics, Operating and Non-operating Conditions

3.3.4Electrical Characteristics

This subsection provides the power requirements for the MegaRAID 8480 RAID controller. Table 3.6 lists the maximum power requirements.

Table 3.6	Maximum Power Requirements
		PCI Express	PCI Express
RAID Controller		+12 V	+3.3 V
MegaRAID 8480		12 W; used only if battery	9 W
		is present

3.3.5Operating and Non-operating Conditions

For the MegaRAID 8480 RAID controller, the operating (thermal and atmospheric) conditions are:

•Relative humidity range is 5% to 90% noncondensing

•Airflow must be at least 200 linear feet per minute (LFPM) to avoid operating the Intel IOP333 processor above the maximum ambient temperature

The parameters for the non-operating (such as storage and transit) environment for the 8480 are:

•Temperature range: −30 °C to +80 °C without battery backup unit

•Temperature range: 0 °C to +45 °C with LSIiTBBU02 battery backup

3.3.6Safety Characteristics

The MegaRAID 8480 RAID 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.
