Before you replace a DIMM in an EF300 or EF600 storage array, review the requirements and considerations.

You must replace a DIMM when a memory mismatch is present, or you have a failed DIMM. Be sure to verify the configuration of your EF300 or EF600 controller to ensure the correct DIMM size is replaced.

Caution Be aware that the DIMMs in your storage array are fragile; improper handling can lead to damage.

Follow these rules to avoid damaging the DIMMs in your storage array:

  • Prevent electrostatic discharge (ESD):

    • Keep the DIMM in the ESD bag until you are ready to install it.

    • Open the ESD bag by hand or cut the top off with a pair of scissors. Do not insert a metal tool or knife into the ESD bag.

    • Keep the ESD bag and any packing materials in case you must return a DIMM later.

      Caution Always wear an ESD wrist strap grounded to an unpainted surface on your storage enclosure chassis.

  • Handle DIMMs carefully:

    • Always use two hands when removing, installing, or carrying a DIMM.

    • Never force a DIMM into a shelf, and use gentle, firm pressure to completely engage the latch.

    • Always use approved packaging when shipping DIMMs.

  • Avoid magnetic fields. Keep DIMMs away from magnetic devices.
