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’.

Figure 4.2

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.
