You can replace any of the six fans in a SAN Volume Controller 2145-SV1 node.
Before you begin
DANGER
Multiple power cords. The product might be equipped with multiple
power cords. To remove all hazardous voltages, disconnect all power cords. (L003)
Take precautions to avoid damage from static electricity. Wear an anti-static wrist strap and use
a static-protected mat or surface.
About this task
Important: You can hot swap a fan. However, using
MAP 5350: Powering off a node to power off the node avoids risking an abrupt power failure on the node, which
avoids the possibility of corrupting data.
To replace the fans, complete the following steps.
Procedure
- Read the safety information.
- Optional: Follow the procedure in MAP 5350: Powering off a node to verify that hosts will not lose access to data in volumes before you power off
the node.
Important: If you decide to hot swap the fan, use MAP 5350 to make all of the necessary
checks. This procedure ensures that the partner node in the I/O group can take over all I/O group
operations, if necessary. It also ensures that there are no dependent volumes on the node. With the
partner node available and no dependent volumes on the node, you do not lose access to data if this
node accidentally powers off.
- Orient the new fan over the appropriate fan slot in the fan-assembly bracket so that the fan
connector aligns with the connector on the system board. This alignment assures that the air-flow
indicator arrow on the side of the fan is pointing to the rear of the node.
- Insert the fan into the fan slot in the fan-assembly bracket, and press it down until it is
seated, as shown in Figure 1.

- Make sure that all cables, adapters, and other components are installed and seated correctly,
and that all internal cables are correctly routed.
- Replace the top cover, as described in Replacing the top covers: 2145-SV1.
- If you removed the node from the rack, replace the node in the rack, as described in Replacing a node in a rack: 2145-SV1.
- If you removed any Fibre Channel or Ethernet cables, replace them in the same ports from which
they were removed.
- If you removed the power cords, replace the power cords and the cable-retention brackets. The node powers on automatically when the power cords are replaced.
