Replace a node
Take the following actions to remove the faulted node from the enclosure and install the replacement node.
Identify a faulted part from PowerStore Manager
Before you replace a part, ensure that you have identified its location within the system. Using PowerStore Manager, you can
identify and locate a faulted part.
Steps
1. From PowerStore Manager, select Hardware.
2. Select the appliance that contains the faulted part.
3. From the Hardware card, select the view of the system where the faulted part is located.
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 Power control procedures.
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.
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
Embedded module LEDs. If the LED is lit, the node has not been properly shut down.
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.
NOTE: If the I/O module and network cables are not already labeled, label them clearly for reconnecting later.
