4-2 Installing the SynchLink Module
Installing the Module You can install or remove the module while chassis power is applied.
Be sure that power is removed or the area is nonhazardous before proceeding.
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.
Figure 4.1
2. Slide the module into the chassis until the module locking 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.
