AVERTISSEMENT: Ports pour fibres optiques – sécurité sur le plan optique

Ne regardez jamais le laser tant qu'il est sous tension. Ne regardez jamais directement le port à fibres optiques et les embouts de câbles à fibres optiques tant qu'ils sont sous tension.

AVERTISSEMENT: L'utilisation de contrôles, de réglages de performances ou de procédures autres que ceux qui sont spécifiés au sein du présent document risquent d'entraîner l'exposition à des rayonnements laser dangereux.

AVERTISSEMENT: Le commutateur ne doit être utilisé qu'avec des modules Transceiver GBIC approuvés par 3Com.
