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.

IMPORTANT: In dual-controller configurations, both controllers must execute the same version of firmware. If the controllers have different firmware versions, the storage system responds as follows: • Cold boot method If a second controller is installed while the device is powered off, the system compares the firmware versions of both controllers at power on and clones the most recent version from one controller to the other controller.
