Replace a Pilot Chassis

Prerequisites:

Ensure that you have a Phillips Number 2 screwdriver with at least a 4-inch shaft.
Before handling a component, touch a grounded surface to discharge any static electricity.
Attach an electrostatic discharge (ESD) wrist strap to your wrist, and stand on an ESD mat while replacing components.
Ensure that you have the correct green color coded CPU removal tool that is used for removing smaller core processors. The CPU tool is shipped with replacement motherboards and replacement CPUs.
Ensure that there is a workbench available to place the Pilot chassis once it is removed from the rack for servicing.
Fail over the Pilot before replacing the component using Guided Maintenance.

Each Oracle Flash Storage System has two Pilots installed in the rack. The Pilot chassis is a field replaceable unit (FRU). Replacing a Pilot chassis requires you to bring the failed Pilot offline and fail over operations to the standby Pilot using Guided Maintenance.

Caution

The Pilot weighs approximately 18.1 kilograms (39.9 pounds). Two people are required to carry the Pilot chassis and install it into the rack.

Caution

Deploy any rack anti-tilt mechanisms before installing the Pilot into the rack.

Important! The replacement Pilot ships as a metal chassis without any pre-existing components inside it. Replacement of the Pilot chassis requires assistance from Oracle Customer Support because it involves removing all FRUs and CRUs from the failed chassis and reinstalling them into the replacement chassis.

Caution

Ensure that all power is removed from the failed Pilot before removing the Pilot chassis. You must disconnect the power cords before performing this procedure.

Note: To replace a Pilot chassis, you must remove the failed Pilot from the rack.

Note: Replacing a chassis is the final option in case of failure. Chassis replacement is not recommended, and is usually not required. However, if the Pilot chassis must be replaced, replace the chassis with the same model. For example: An X4-2 Pilot can only be replaced with an X4-2 Pilot and an X5-2 Pilot can only be replaced with an X5-2 Pilot.

Note: Using Guided Maintenance ensures that none of the re-used components have failed in case the replacement Pilot is re-using pre-existing components (CRUs and FRUs) from the failed Pilot.
