Before you begin
CAUTION:
When handling system components, there is a danger to
equipment from electrostatic discharge (ESD). Use proper
anti-static protection at all times:
• Keep the replacement component in the ESD bag until needed.
• Wear an ESD wrist strap grounded to an unpainted surface
of the chassis.
• If an ESD wrist strap is unavailable, touch an unpainted surface
of the chassis before handling the component.
• Never touch connector pins.
CAUTION:
Be sure the replacement is available before removing the failed
component. Removing a component impacts airflow and cooling
within the enclosure.
IMPORTANT:
This controller replacement does not include a cache module
or batteries. You must remove these components from the failed
controller and install them on the replacement controller.
