FRU Replacement Strategy
Before Replacing Parts
Ensure that all s oftware fixes are installed prior to
replacing any FRUs listed in this manual.
Use the following strategy to prevent unnecessary FRU
replac ement and s ervic e expens e:
·
 If you are instructed to replace a FRU and that
does not correct the problem, reinstall the
original FRU before you continue.
·
  Some c omputers have both a proc ess or board and a
mainboard.  If you are instructed to replac e either the
proc ess or board or the mainboard, and the first board
that you replac ed does not c orrect the problem,
reinstall the original board, and then replac e the other
(proc ess or or s ystem) board.
·
  If an adapter or devic e c onsists of more than one
FRU, an error c ode may be c aus ed by any of the
FRUs.  Bef ore replacing the adapter or device,
remove the FRUs, one by one, to s ee if the
symptoms change.  Replac e only the f aulty FRU.

saf ety notic e f ound in this s ection.
The following s af ety notic es are provided in English, French,
German, Italian, and Spanis h languages.
Safety Notice 1
Bef ore the c omputer is powered-on after FRU
replacement, make sure all screws, springs, or other
small parts are in plac e and are not left loos e inside the
computer. Verif y this by s haking the c omputer and
listening for rattling s ounds. Metallic parts or metal flakes
can c aus e elec tric al shorts.
Avant de remettre lordinateur s ous tension après
remplac ement dune unité en clientèle, vérifiez que tous
les ress orts, vis et autres pièc es s ont bien en plac e et
bien fixées.  Pour ce faire, secouez lunité et assurez-
vous  quaucun bruit sus pect ne s e produit.  Des pièc es
métalliques ou des copeaux de métal pourraient causer
un c ourt-circuit.
Bevor nac h einem FRU-Austausch der Computer wieder
angeschlossen wird, muß sichergestellt werden, daß
keine Schrauben, Federn oder andere Kleinteile f ehlen
oder im G ehäus e vergess en wurden.  Der Computer muß
geschüttelt und auf klappergeräusche geprüft werden.
Metallteile oder splitter können Kurzschlüsse erzeugen.
Prima di acc endere lelaboratore dopo c he è stata
effettuata la sostituzione di una FRU, accertarsi che tutte
le viti, le molle e tune le altri parti di piccole dimensioni
siano nella c orretta posizione e non siano spars e
allinterno dellelaboratore.  Verificare ciò scuotendo
lelaboratore e pres tando attenzione ad eventuali rumori;
eventuali parti o pezzetti metallici poss ono provoc are
cortocircuiti peric olos i.
Antes de enc ender el sistema des pues  de sustituir una
FRU, compruebe que todos los tornillos, muelles y demás
piezas  pequeñas s e encuentran en su sitio y no s e
encuentran sueltas dentro del sistema.  Compruébelo
agitando el sistema y escuchando los posibles  ruidos que
provoc arían. Las  piezas metálic as pueden c aus ar
c or t oc irc u it os  el éc tric os .

Though main batteries have low voltage, a s horted or
grounded battery c an produc e enough c urrent to burn
combustible materials or pers onnel.
Bien que le voltage des batteries principales soit peu
élevé, le c ourt-circuit ou la mis e à la mass e dune batterie
peut produire suffisamment de c ourant pour brûler des
matériaux c ombustibles ou c aus er des brûlures
corporelles graves .
Obwohl Hauptbatterien eine niedrige Spannung haben,
können sie doc h bei Kurzschluß oder Erdung genug
Strom abgeben, um brennbare Materialien zu entzünden
oder Verletzungen bei Pers onen hervorzurufen.
Sebbene le batterie di alimentazione siano a basso
voltaggio, una batteria in corto circuito o a massa può
fornire c orrente sufficiente da bruciare materiali
combustibili 0 provoc are ustioni al tecnici di
manutenzione.
Aunque las baterías principales tienen un voltaje bajo,
una batería c ortocircuitada o c on c ontacto a tierra puede
producir la c orriente suficiente c omo para quemar
material c ombustible o provoc ar quemaduras en el
pers onal.
Safety Notice 6
