Removing and Installing the RSC Card

Removing or installing the RSC card while the system has the AC power cord connected could damage your system or your RSC card. Only qualified service personnel should remove or replace the RSC card. Contact your qualified service representative to perform this service operation.

Before you follow the procedures in the Sun Fire 280R Server Service Manual or Sun Fire 880 Server Service Manual to remove or install the RSC card, perform this procedure to ensure that there is no AC power present in the system.

1. Shut down and halt the system.

2. With the system at the ok prompt, turn the keyswitch to the Off position.

   Standby power is still present in the system at this point.

3. Disconnect all AC power cords from their back panel receptacles.

   This ensures that there is no standby power voltage present in the system.

4. Follow the procedure you require in your service manual.
