4-2 Installing the Drive Module
Installing the Module You can install or remove the module while chassis power is applied.
1. Align the circuit board with the top and bottom chassis guides.
WARNING
!
When you insert or remove the module while
backplane power is on, an electrical arc can occur.
This could cause an explosion in hazardous location
installations. Be sure that power is removed or the
area is nonhazardous before proceeding.
ATTENTION
!
The removal of a Drive Module while under power
may cause personal injury or property damage. Make
sure that removal of the module does not adversely
impact other parts of the system.
IMPORTANT
Repeated electrical arcing causes excessive wear to
contacts on both the module and its mating
connector. Worn contacts may create electrical
resistance that can affect module operation.
