10. SMBus connector (6-1 pin J5)
This connector allows you to connect SMBus (System Management
Bus) devices. Devices communicate with an SMBus host and/or other
SMBus devices using the SMBus interface. SMBus is a specific
implementation of an I
2 C bus, a multi-device bus that allows multiple
chips to connect to the same bus and enable each one to act as a
master by initiating data transfer.
11. Zero Channel RAID slot (PCIX1)
The 64-bit/100MHz PCI-X slot (colored green) supports the Adaptec
Nighthawk2 ASR-2010S Zero-Channel RAID card or the Intel RAID
Controller SRCZCR to provide advanced RAID functionality. The RAID
card supports RAID levels 0, 1, 5, multilevel 0/1 and 0/5, cache
memory modules with ECC, and predictive caching capability.
