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.
About this task
WARNING:
Do not remove the node within five minutes of system power down to ensure that the system has
had time to complete caching.
CAUTION:
Do not remove a node while the "Unsafe to remove" LED is lit. The location of this LED is described
in
. If the LED is lit, the peer node has been powered down or is offline and this node
should not be removed.
CAUTION:
Because nodes include cooling fans, they should be removed for as short a time as possible. Do not
remove nodes from a live system unless replacement parts are available.
