3.5 Precautions
Warning Read the installation instructions before connecting
the system to the power source.
Attention Avant de brancher le système sur la source
d'alimentation, consulter les directives d'installation.
Warnung Vor dem Anschließen des Systems an die
Stromquelle die Installationsanweisungen lesen.
Warning This product relies on the building's installation for
short-circuit (overcurrent) protection. Ensure that a
fuse or circuit breaker no larger than 120 VAC, 15A
U.S. (240 VAC, 10A international) is used on the
phase conductors (all current-carrying conductors).
Attention Pour ce qui est de la protection contre les courts-
circuits (surtension), ce produit dépend de
l'installation électrique du local. Vérifier qu'un
fusible ou qu'un disjoncteur de 120 V alt., 15 A U.S.
maximum (240 V alt., 10 A international) est utilisé
sur les conducteurs de phase (conducteurs de
charge).
Warnung Dieses Produkt ist darauf angewiesen, daß im
Gebäude ein Kurzschluß- bzw. Überstromschutz
installiert ist. Stellen Sie sicher, daß eine Sicherung
oder ein Unterbrecher von nicht mehr als 240 V
Wechselstrom, 10 A (bzw. in den USA 120 V
Wechselstrom, 15 A) an den Phasenleitern (allen
stromführenden Leitern) verwendet wird.
Warning The plug-socket combination must be accessible at
all times, because it serves as the main disconnecting
device.
Attention La combinaison de prise de courant doit être
accessible à tout moment parce qu'elle fait office de
système principal de déconnexion.
Warnung Vor dem Anschließen des Systems an die
Stromquelle die Installationsanweisungen lesen.

Precautions
HOA 7100 MAXLink Optical Amplifier Product Manual Rev C (4/05) 3–5
Warning The unit has more than one power supply
connection; all connections must be removed to
remove all power from the unit.
Attention Cette unitè est èquipèe de plusieurs raccordements
d’alimentation. Pour supprimer tout courant
èlectrique de l’unitè, tous les cordons d’alimentation
doivent ètre dèbranchès.
Warnung Diese Einheit verfügt über mehr als einen

fernzuhalten, müssen alle Stromzufuhren abgetrennt
sein.
Warning To prevent bodily injury when mounting or
servicing this unit in a rack, you must take special
precautions to ensure that the system remains stable.
The following guidelines are provided to ensure
your safety:
• This unit should be mounted at the bottom of the
rack if it is the only unit in the rack.
• When mounting this unit in a partially filled rack,
load the rack from the bottom to the top with the
heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices,
install the stabilizers before mounting or servicing
the unit in the rack.
Attention Pour éviter toute blessure corporelle pendant les
operations de montage ou de réparation de cette
unité en casier, il convient de prendre des
précautions spéciales afin de maintenir la stabilité
du système.
Les directives ci-dessous sont destinées à assurer la
protection du personnel:
• Si cette unité constitue la seule unité montée en
casier, elle doit être placée dans le bas
• Si cette unité est montée dans un casier
partiellement rempli, charger le casier de bas en
haut en plaçant l'élément le plus lourd dans le bas.
• Si le casier est équipé de dispositifs stabilisateurs,
installer les stabilisateurs avant de monter ou de
réparer l'unité en casier.
