What to Do

Caution – The system supplies power to the system controller (SC) card even when
the system is powered off. To avoid personal injury or damage to the SC card, you
must disconnect the AC power cords before servicing the SC card.
1. Disconnect the AC power cords from the back of the system.
Caution – If you are using an antistatic wrist strap to protect against electrostatic
discharge, connect it to a properly grounded surface, such as a nearby equipment
rack, or a nearby system that is connected to a power source.
