• Never hand a circuit pack from a grounded to a non-grounded
person or vice-versa.
1. Open the front door of the Galaxy SC by pulling down on the top
sides of the door. Assure that all necessary circuit packs are
provided. Refer to Figure 3-1 and Table 3-A.
Each of the Basic Controller packs is required, but BJC Rectifier
Interface Packs are only necessary for the Rectifier Interface
Module positions in use. Refer to the appropriate
engineering/ordering information to determine the optional packs
necessary on the Intelligent side, if any.
2. Disengage all of the equipped packs by pulling down on the circuit
pack latch and sliding the board away from the backplane. Do not
remove the board completely from the guides.
