51 RAID Controller Location It has a 32 bit, 33 MHz maximum PCI interface and features scatter-gather bus mastering, which enables it to perform high speed data transfers on the PCI bus. It operates in either full duplex mode or half duplex mode. It has a four wire interface to a serial EEPROM, which can provide power-on initialization and software configuration. The firmware interface is primarily through the PCI interface, but a four-wire serial EEPROM interface can provide power-on initialization. The diagnostic interface is through the PCI interface. The ethernet circuit board connects to the controller circuit board through a 114 pin Mictor impedance controlled connector. The electrical interface is with the primary PCI bus (host bus) on the controller circuit board. In addition to the PCI signals, this connector provides the 3.3 V power for the ethernet circuit board. The power required for this board is a maximum of 860 mA at 3.3 V, approximately 2.85 W. The RAID controller is installed in the rear of the enclosure in the location shown in Figure 4-2.

RAID Controller Circuit Boards
51
It has a 32 bit, 33 MHz maximum PCI interface and features
scatter-gather bus mastering, which enables it to perform
high speed data transfers on the PCI bus. It operates in either
full duplex mode or half duplex mode. It has a four wire
interface to a serial EEPROM, which can provide power-on
initialization and software configuration.
The firmware interface is primarily through the PCI
interface, but a four-wire serial EEPROM interface can
provide power-on initialization. The diagnostic interface is
through the PCI interface.
The ethernet circuit board connects to the controller circuit
board through a 114 pin Mictor impedance controlled
connector. The electrical interface is with the primary PCI
bus (host bus) on the controller circuit board. In addition to
the PCI signals, this connector provides the 3.3 V power for
the ethernet circuit board. The power required for this board
is a maximum of 860 mA at 3.3 V, approximately 2.85 W.
