The PCI CM block diagram is shown in Figure 5. … … 27 25 The physical form-factor for the Chassis Manager is a 2U PCI card measuring approximately 4.75 x 2.5 in. The Node ID box is on a board measuring approximately 2.25 x 1.75 in. Appropriate sockets permit the RCM3700 module to plug directly into the PCI card or optionally through a 10 pin ribbon cable for remote mounting. 28 26 29 ==== Major Hardware Components====27 ===== Major Hardware Components ===== 30 28 31 ===== RCM3700 ===== 29 ''' RCM3700 ''' 32 30 33 31 [[Image(RCM3700.jpg,align=right,title="Rabbit Semiconductor RCM 3700",200)]] 34 32 35 The [http://www.rabbitsemiconductor.com/documentation/docs/manuals/RCM3700/index.htm RCM3700 Rabbit Core] is the microprocessor based core module designed for Ethernet/Internet applications with the following features:33 The [http://www.rabbitsemiconductor.com/documentation/docs/manuals/RCM3700/index.htm RCM3700 Rabbit Core] is the microprocessor based core module designed for !Ethernet/Internet applications with the following features: 36 34 37 35 * Small Footprint: 2.95” x 1.2”; 100ma @ 5v … … 48 46 Note: The Dynamic C TCP/IP library functions are slightly different from Unix syntax, and are not directly portable to non-Rabbit platforms. 49 47 50 ===== DS1780 ===== 48 ''' DS1780 ''' 51 49 52 50 [[Image(DS1780.jpg,align=right,title="DS1780 Functional Block Diagram",200)]] Voltage and temperature monitoring is achieved using the I2C-based Dallas Semiconductor DS-1780. This device is a 24-pin direct-to-digital chassis system monitor. It is capable of monitoring ambient temperature, six power supply voltages, and the speed of two fans. Fan speed can also be controlled from this device using an internal 8-bit ADC. … … 54 52 [[BR]][[BR]][[BR]][[BR]][[BR]][[BR]] 55 53 56 ===== TPIC2810 ===== 54 ''' TPIC2810 ''' 57 55 58 56 [[Image(TPIC2810.jpg, align=right, title="TPIC2810 Block Diagram",200)]] … … 60 58 [[BR]][[BR]][[BR]][[BR]][[BR]][[BR]] 61 59 62 ===== P82B96 ===== 60 ''' P82B96 ''' 63 61 64 62 [[Image(P82B96.jpg,align=right,title="P82B96 Block Diagram",200)]] … … 67 65 [[BR]][[BR]][[BR]][[BR]][[BR]][[BR]] 68 66 69 ===== PCA9554 ===== 67 ''' PCA9554 ''' 70 68 71 69 [[Image(PCA9554.jpg,align=right,title="PCA9554 Block Diagram",200)]] … … 74 72 [[BR]][[BR]] 75 73 76 ===== PCA8581 ===== 74 ''' PCA8581 ''' 77 75 78 76 [[Image(PCA8581.jpg,align=right,title="PCA8581 Block Diagram",200)]] … … 81 79 [[BR]] 82 80 83 ===== PCF8570 ===== 81 ''' PCF8570 ''' 84 82 85 83 The 256 x 8 PCF8570 I2C RAM device is included in the CM design for future use, and is not used on the initial CM boards.
