 == Crate info ==
 * 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.
  

 == IMPORTANT NOTES ==
* The COB's insertion lever's sensor is broken and you must run clia commands to install/uninstall it. This involves commands typed into the shelf manager (talk to Dan) 
  
 To install: Insert COB as you normally would and then run the following command to tell the shelf the lever is correctly set
 
  {{{ clia sendcmd 0x96 0x2e 0x08 0x0a 0x40 0x00 0x00 0x01 }}} 

  Where 0x96 is the IPMI address for the physical slot 2 and logical slot 11

 To remove: Type the following command to simulate the lever being opened
  
  {{{ clia sendcmd 0x96 0x2e 0x08 0x0a 0x40 0x00 0x00 0x00 }}}
  
  Wait for the COB state to be inactive and then remove it physically.
