Removal and replacement procedures  47 
 
CAUTION: When removing and lifting the rear cage, always grasp the handholds as far 
forward as possible. The front end of the rear cage is heavy and the handholds provide a more 
balanced location to distribute the weight of the cage during lifting. 
 
 
 
CAUTION: When removing the rear cage and midplane assembly, the connectors on the 
midplane assembly are susceptible to damage. Use caution to avoid damage to the pins and 
connectors. 
 
e.  Use the handholds to extend and remove the rear cage from the enclosure. 
 
To replace the component, reverse the removal procedure.
