Replacing a VNXe3100 Memory Module

Before you start

Before you begin the replacement procedure, make sure you have correctly identified the faulted part,

and that a replacement memory module (DIMM) is available. Refer to your EMC® VNXe™ online help

(Servicing your system > Adding or replacing faulted hardware components > Replace a faulted

hardware component) for instructions on how to identify failures, order new parts, and handle

hardware components. Also, prepare your disk processor enclosure (DPE) for service as described

below.

Preparing your disk processor enclosure for service

IMPORTANT

To protect your VNXe system from accidental data loss while you remove and replace DPE

components, open Unisphere™ and select Settings, then Service System.

• Log in with your service password.

•In the System Components column, select the storage processor (A or B) associated with the

faulted component.

•Under Service Actions, select Enter Service Mode, then Execute service action.

The storage processor fault LED will flash alternating amber and blue while the SP remains in

Service Mode and is receiving active power.
