- If you removed a rubber cover from the battery holder,
use your fingers to install the battery cover on top of the battery
connector.
- 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.
- If you removed the node from the rack, replace the node
in the 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.
- Lift the locking levers ( 1 in Figure 3) on the slide rails
and push the node 2 all the way into
the rack until it clicks into place.

- Turn on
the
node.
- If a problem causes you to restart the node, see MAP 5900: Hardware boot. Then, connect a monitor and
keyboard to the system and reset the BIOS date and time.
