What to remove or install: A power supply.
Tools you need: None. 
System shutdown: You can replace one of the two power supplies in a 
455mod8 module, without powering down the 
module or stopping applications that use the disk 
drives in the module.
If you are replacing a power supply in a 455DS 
module, you must first stop all software that is 
currently using the disk drives in that module.
