Install the Module
You can install or remove the module while chassis power is applied.
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.
1. Align the circuit board with the top and bottom chassis guides.
2. Slide the module into the chassis until module tabs ‘click’.
!
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.
