Disconnecting the power cords from an 8335-GCA or 8335-GTA system

Learn how to disconnect the power cords from an IBM® Power® System S822LC (8335-GCA and 8335-GTA) system.

1. Open the rear rack door on the system unit that you are servicing.
2. Identify the system unit that you are servicing in the rack.
3. Label and disconnect the power cords from the power supply handle. Unfasten the hook and loop fastener that ties the power cord to the power supply handle. Note how the power is looped; you will need to make that same loop when you reattach the power cords. There are two types of loops, detailed in Figure 1 and Figure 2.
   Figure 1. Power cord loop with cable management arm routing. The power cord loops counter-clockwise to the right.

   
   Figure 2. Power cord loop with sidewall routing. The power cord loops counter-clockwise to the left.

   
4. Disconnect the power cords from the system unit. See figure Figure 3.
   Note: This system might be equipped with two or more power supplies. If the removing and replacing procedures require the power to be off, then ensure that all the power sources to the system have been completely disconnected.
