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 fan module from PowerStore Manager
Before you replace a fan module, ensure that you have identified its location within the system. Using PowerStore Manager, you
can identify and locate a faulted fan module.
Steps
1. From PowerStore Manager, select Hardware.
2. Select the appliance that includes the fan module that you need to replace.
3. On the Components card, under Internal View, expand the node that includes the fan module, and then select the relevant
FanModule.
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. 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.
Steps
1. Rotate the power cable retention bail to the left (right for top power supply). Disconnect the power cable from the power
supply.
