DC Power Related Cautions/Warnings
This section lists cautions and warnings for the hardware when DC power supplies are installed:
CAUTION: RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN
INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE
INSTRUCTIONS" (Cl. 1.7.15)
French Translation:
ATTENTION: RISQUE D'EXPLOSION SI LA BATTERIE EST REMPLACÉE
PAR UN MODÈLE DE TYPE INCORRECT. METTEZ AU REBUT LES
BATTERIES USAGÉES CONFORMÉMENT AUX INSTRUCTIONS (CL.
1.7.15)
CAUTION: Equipment may be affected by electrostatic discharge. ESD reduction
procedures (wearing a wrist strap) must be implemented during the installation and
maintenance of equipment.
CAUTION: Shielded interface cables which are grounded must be used to ensure
agency compliance with electromagnetic emissions (EMC).
WARNING: Laser radiation exposure should be avoided. Cover any unused fiber
optical ports. Do not look directly at exposed fiber optical transmitters or cables.
WARNING: To reduce the risk of electric shock, disconnect all power supply
cords before servicing the switch (the switch might have more than one).
French Translation:
Pour réduire le risque de choc électrique, débranchez tous les câbles d'alimentation
avant d'intervenir sur le commutateur (il peut en comporter plusieurs).
WARNING: You must shut off the electric current to the DC feed wires before
connecting or disconnecting the wires from the DC power supply.
