Figure 3-9. Removing and Installing the Midplane
NOTE:
If you replace a midplane on an existing enclosure, you must reset
your Service Tag information. Consult with your Dell service representative if
you are not familiar with this process.
Also, if you modified the temperature warning thresholds to be different from
the default enclosure values, use your management software to restore your
desired temperature threshold values. For more information, see your
management software documentation.
