J_BP_SIG1 (Backplane to system board) Removing the backplane Prerequisites CAUTION: To prevent damage to the drives and backplane, remove the drives from the system before removing the backplane. CAUTION: Note the number of each drive and temporarily label them before you remove the drive so that you can reinstall them in the same location. NOTE: The procedure to remove the backplane is similar for all backplane configurations. 1. Follow the safety guidelines listed in the Safety instruction. 2. Follow the procedure listed in the Before working inside your system. 3. Remove all the drives. NOTE: To avoid damaging the backplane, ensure to move the control panel cables from the cable routing clips before removing the backplane. 4. Disconnect all the cables that are connected to the backplane. NOTE: Observe the routing of the cable as you remove it from the system. Steps 1. Pull the plunger to disengage the drive backplane from the lock hole on the drive cage. 2. Lift the drive backplane out of the drive cage. 82 Installing and removing system components
