ESD-prevention procedures when removing and replacing components to avoid these problems.
Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. If no wrist strap is available, ground
yourself by touching the metal part of the chassis.
Periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms
(Mohms).
L’équipement électrique génère de la chaleur. La température ambiante peut ne pas être adéquate pour refroidir
l’équipement à une température de fonctionnement
acceptable sans circulation adaptée. Vérifiez que votre site
propose une circulation d’air adéquate.
Vérifiez que le couvercle du châssis est bien fixé. La conception du châssis permet à l’air de refroidissement de bien
circuler. Un châssis ouvert laisse
l’air s’échapper, ce qui peut interrompre et rediriger le flux d’air frais destiné aux
composants internes.
Les décharges électrostatiques (ESD) peuvent endommager l’équipement et gêner les circuits électriques. Des
dégâts d’ESD surviennent lorsque des co
mposants électroniques sont mal manipulés et peuvent causer des pannes
totales ou intermittentes. Suivez les procédures de prévention d’ESD lors du retrait et du remplacement de
composants.
Portez un bracelet anti-
ESD et veillez à ce qu’il soit bien au contact de la peau. Si aucun bracelet n’est disponible,
reliez votre corps à la terre en touchant la partie métallique du châssis.
Vérifiez régulièrement la valeur de résistance du bracelet antistatique, qui doit être comprise entre 1 et 10
mégohms (Mohms).
Mounting Installation Precautions
The following should be put into consideration for rack-mount or similar mounting installations:
Do not install and/or operate this unit in any place that flammable objects are stored or used in.
The installation of this product must be performed by trained specialists; otherwise, a non-specialist might create
the risk of the system’s falling to the ground or other damages.
Lanner Electronics Inc. shall not be held liable for any losses resulting from insufficient strength for supporting the
system or use of inappropriate installation components.
Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given
to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified
by the manufacturer.
Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of airflow required for
safe operation of the equipment is not compromised.
Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and
the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when addressing this concern.
Reliable Grounding - Reliable grounding of rack mounted equipment should be maintained. Particular attention
should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).
