Replacing the fans: 2145-CG8 or 2145-CF8

Replace any of the five fans in a SAN Volume Controller 2145-CG8 or 2145-CF8 node.

Before you begin

Attention: To ensure proper operation, replace a failed fan within 30 seconds.

Take precautions to avoid damage from static electricity. Wear an anti-static wrist strap and use a static-protected mat or surface. For more information, see Handling static-sensitive devices.

About this task

Important: You can hot swap a fan. However, using MAP 5350: Powering off a node to power off the node through proven methods avoids risking an abrupt power failure on the node, which avoids the possible corruption of data.

Perform the following steps to replace a fan:

Procedure

Read the safety information to which Preparing to remove and replace parts refers.
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 that ensure that the partner node in the I/O group can take over all I/O group operations, if necessary, and that there are no dependent VDisks on the node. With the partner node available and no dependent VDisks on the node, you do not lose access to data if this node accidentally powers off.
Slide the node forward to remove the cover and expose the fans and fan connectors, as described in Removing the top cover: 2145-CG8 or 2145-CF8.
Figure 1 shows fan locations within the SAN Volume Controller 2145-CG8 or 2145-CF8 node.

- 2 Fan 2
- 3 Fan 3
- 4 Fan 4
- 5 Fan 5
- 6 Fan tabs
- 7 Fan connector on the system board
- 8 Fan connector
- 9 Side view of fan showing air-flow indicator
The node has five fan positions that are numbered from right to left.
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.

Figure 2 shows a fan being replaced.

Insert the fan into the fan slot in the fan-assembly bracket and press it down until it is seated correctly in the slot and the fan connector is seated correctly in the connector on the system board.
Make sure that all cables, adapters, and other components are installed and seated correctly and that you have not left loose tools or parts inside the node. Make sure that all internal cables are correctly routed. If you disconnected the Fibre Channel and Ethernet cables, make sure that each cable is reconnected to the same port from which it was removed.
Replace the top cover. See Replacing the top cover.
If you removed the node from the rack, replace the node in the rack, as described in Replacing a node in a rack.
If you removed any Fibre Channel or Ethernet cables, use the labels you that placed on each cable to identify the ports from which they were removed.
If you removed the power cords, replace the power cords and the cable-retention brackets, as described in Replacing the cable-retention bracket.
Lift the locking levers ( 1 in Figure 3) on the slide rails and push the server 2 all the way into the rack until it clicks into place.
