Power Supply for SAS 9280 RAID Controllers

Note:

+12V is used in the charging circuitry for the battery pack
on the optional iBBU battery-backed daughter card. If the
iBBU daughter card is mounted, the following power
consumption figures apply:

–

During fast charging of the battery pack: 230mA in +12V

Operating and Non-operating Conditions for SAS 9280 RAID Controllers

The operating (thermal and atmospheric) conditions for the SAS 9280-8e
RAID controller are:

•

Relative humidity range is 5% to 90% noncondensing.

•

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 the controller are:

•

Temperature range:

−30 ° C to +80 ° C without battery backup unit.

•

Temperature range: 0

° C to +45 ° C with iBBU battery backup.

Safety Characteristics

All MegaRAID 6Gb/s SAS RAID controllers meet or exceed 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. For the boards installed in a PCI Express bus slot, all voltages are
lower than the SELV 42.4V limit.
