a.Disconnect the in-line connector on the battery cable.

b.Pull the battery pack/shield assembly away from the ACM—it is secured with a double-sided adhesive-backed foam tape.

c.If necessary, clean any residue from the adhesive-backed foam tape that secured the old battery pack to the cooling module. The replacement battery pack requires a clean, smooth surface.

￿Green power supply indicator (bottom LED) — lights when all DC output voltages are within normal operating ranges

￿Amber power supply fault indicator (top LED) — lights if a fault is detected in the power supply
