Replace A Dual Inline Memory Module (Dimm); Before You Begin; Identify A Faulted Dimm From Powerstore Manager; Power Down The Node - Dell EMC PowerStore 500T Installation And Service Manual

Replace a dual inline memory module (DIMM)

Take the following actions to remove the faulted DIMM and install the replacement DIMM into the system.
The DIMMs are located within the node. You can access the DIMMs by removing the node from the chassis and opening the top
cover.
NOTE: The DIMMs must stay in their original position. Do not move any DIMMs to a different slot.

Before you begin

CAUTION: Before starting this procedure, use the PowerStore Manager Hardware view and Alerts view to verify
that the appliance and peer node are healthy with no outstanding alerts. If multiple nodes need to be removed
while performing this procedure, repeat this verification for each affected node before proceeding to remove
the next node. If necessary, contact your service provider before starting the replacement procedure.

Identify a faulted DIMM from PowerStore Manager

Before you replace a DIMM, ensure that you have identified its location within the system. Using PowerStore Manager, you can
identify and locate a faulted DIMM.
Steps
1. From PowerStore Manager, select Hardware.
2. Select the appliance that includes the DIMM that you need to replace.
3. On the Components card, under Internal View, expand the node that includes the DIMM, and then select the relevant
DIMM.
Faulted parts appear in red in the image of the system, and report a status of Faulted in the State field.

Power down the node

Power down the node as described in

Remove the node

This procedure describes how to remove a node from the chassis. There are two nodes. The top node is considered to be
upside-down and mirrors the bottom node. The procedure for removing the top node and the bottom node is the same.
Prerequisites
If the I/O modules and network cables are not already labeled, label them clearly for reconnecting later.
