4. 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.
5. Replace the top cover. See “Replacing the top cover” on page 81.
6. 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.
7. 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.
8. 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.
9. Lift the locking levers (1 in Figure 141) on the slide rails and push the server 2 all the way into
the rack until it clicks into place.
10. Turn on the node.
11. If there is a problem restarting the node, see MAP 5900 in the IBM System Storage SAN Volume
Controller Troubleshooting Guide; then connect a monitor and keyboard to the system and reset the
BIOS date and time.
