Preparing the 9105-41B, 9105-42A, or 9786-42H system for operation after removing and replacing the control panel cable

To prepare the system for operation after removing and replacing a control panel cable, complete the steps in this procedure.

1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged into a ground jack or connected to an unpainted metal surface. If not, do so now.
2. Replace the service access cover.
   1. Ensure that the cover latch is open.
   2. Position the access cover over the system unit.
   3. Slide the access panel towards front of the system until the access panel locks into position.
   4. Press down to close the release latch.

      

      

3. For a rack-mounted system, complete the following steps to place the system in the operating position.
   1. Unlock the blue rail safety latches by pushing them inward.
   2. Push the system unit back into the rack until both release latches lock the system into position. Ensure that the cable management arms can move freely.

      

4. For a rack-mounted system, gently push the front cover in until the cover snaps into place.
   The cover has indentations where you can hold it more easily. Use the alignment pins to secure the cover to the system.
5. For a stand-alone system, install the front cover and door by completing these steps.
   1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged into a ground jack or connected to an unpainted metal surface. If not, do so now.
   2. Align the cover until the two cover tabs are seated into the slots on the base plate.

      

   3. Rotate the cover up and towards the system until the release latch is seated into its respective slot.
   4. Twist the cover latch to the right (clockwise) to lock the cover. Vertical is locked; horizontal is unlocked.

      

   5. Close the front door. Insert the front door key into the lock. Twist the key to the right (clockwise) to lock the door. Horizontal is locked; vertical is unlocked.

      

6. If you removed the power cords, use your labels to reconnect the power cords to the system unit.
   Fasten the power cords to the system using the hook-and-loop fasteners.

   

7. When the system comes up to the standby state (the power-on LED on the control panel is flashing slowly), continue to the next step.
8. Start the system. For instructions, see Starting a system.
9. Turn off the identify LED. For instructions, see Deactivating an identify LED.
