  * The shelf manger is at 192.168.10.171.  This conflicts with something from the rarp server running on cmssun1, so shut it down if you want to talk to the shelf manager. 
  
+** Sending Raw hex commands to read sensor data:
+
+  The following example uses the ipmitool raw command to get temperature data from FanTray 1
+  
+  The argument 0x04 signifies SensorEvent
+  
+  The argument 0x2d means read sensor data
+  
+  235 is the sensor number, in this case the temperature reading for FanTray1.
+
+ {{{
+[bkilian@cmssun1 ~]$ ipmitool -I lan -H 192.168.10.171 -P "" -t 0x20 raw 0x04 0x2d 235
+ 17 c0 c0
+}}}
+
+  The first value displayed, 17, is the HEX value of the temperature. c0 c0 signify the sensor status and the state mask.
+
+* Fan Speed
+
+  To read the temperature of the FanTrays, use as the final argument:
+    240 - FanTray1
+    
+    241 - FanTray2
+
+    242 - FanTray3
+
+    243 - FanTray4
+
+  The resulting hex value multiplied by 46 is the fan speed in RPM. For example,
+{{{
+[bkilian@cmssun1 work]$ ipmitool -I lan -H 192.168.10.171 -P "" -t 0x20 raw 0x04 0x2d 243
+ 2c c0 c0
+}}}
+  gives us 2c, or 44, for fan speed. The actual fan speed is 44*46 = 2024 RPM
+
+* Temperature
+
+  To read the fan speed of each fan, use as the final argument:
+    235 - FanTray1
+    
+    236 - FanTray2
+
+    237 - FanTray3
+
+    238 - FanTray4
+
+  The first number that is output is the hex value, in degrees Celsius, of the exhaust of the fan.
