Remove the Energy Storage Backplane

---

Caution - Performing a complete power down of the system ensures that any residual power in the ESMs is discharged by the time you remove the ESM. Never attempt to remove an ESM unless the blue Ready-to-Remove LED on the front of the ESM is illuminated or the power has been completely removed from the system.

---

1. Power off the system.

   Refer to Completely Power Off the System.

2. Attach an antistatic wrist strap.

   Refer to Perform Static Discharge Procedures.

3. Remove all of the ESMs.
4. Remove the system from the rack.

   Refer to Remove the Chassis From the Rack.

5. Remove the rail glides from the chassis.

   Depending on the type of rail kit you have installed, removing these glides will involve one of the following procedures:

   • Release the locking tab and slide each rail glide off the chassis mounting studs.
   • Remove the screws that secure the glide to the chassis.
6. Remove the top chassis cover.

   Refer to Access Internal Components.

7. Remove two cables from the backplane as shown in Removing Cables From the Backplane.

8. Using a No. 2 Phillips screwdriver, remove two screws from each side of the chassis as shown in panel 1 of Removing the Energy Storage Backplane.
9. Slide the entire assembly toward the front of the system as shown in panel 2 of Removing the Energy Storage Backplane, then lift it up as shown in panel 3 of Removing the Energy Storage Backplane.

   Place the assembly upright with the front of the assembly on a firm surface and an antistatic mat beneath it.

10. Using a No. 2 Phillips screwdriver, remove the five screws that secure the backplane to the energy storage cage. Using a No. 1 Phillips screwdriver, also remove the two screws on the far left and the two screws on the far right end of the backplane. Refer to panel 4 of Removing the Energy Storage Backplane.
11. Lift the board off of the energy storage cage as shown in panel 5 of Removing the Energy Storage Backplane.
