The node has six fan positions that are numbered from right to left.
4. 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 245 shows a fan being replaced.
5. 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.
6. 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.
7. Replace the top cover. See “Replacing the top cover” on page 81.
8. If you removed the node from the rack, replace the node in the rack, as described in “Replacing the
SAN Volume Controller in a rack” on page 55.
9. If you removed any Fibre Channel or Ethernet cables, use the labels you placed on each cable to
replace all Fibre Channel and Ethernet cables in the same ports from which they were removed.
10. If you removed the power cords, replace the power cords and the cable-retention brackets, as
described in “Replacing the cable-retention bracket” on page 39.
11. Lift the locking levers (1 in Figure 246 on page 247) on the slide rails and push the server 2 all
the way into the rack until it clicks into place.
