9-4 Upgrading Your Server
CONFIRMATION AFTER INSTALLATION/REMOVAL
Confirm the following after installing an additional option and removing a component:
„
Installing removed components exactly as they were
Install the components and cables, which were removed and disconnected for addition of
an option, exactly as they were. Assembling without a component being installed or a
cable being disconnected causes the server to malfunction.
„
Confirming that no parts such as screws are left in the server
Confirm that particularly conductive parts such as screws are not left in the server.
Turning on the power with a conductive part on the mother board or cable terminal causes
the server to malfunction.
„
Confirming the cooling effect in the server
Confirm that the ventilating holes are not covered with an internally connected cable.
Insufficient cooling effect raises the internal temperature, which causes the server to
malfunction.
„
Confirming operation with a tool
Some additional devices require the diagnostic utility or BIOS SETUP utility to check if
they are installed correctly. For details, see the procedure for additionally installing the
target device.
