DC Power Related Cautions/Warnings
This section lists cautions and warnings for the hardware when DC power supplies are installed:
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: (PA-7050 Firewall) When removing a fan tray, it is recommended that you
first pull the fan tray out one inch and then wait 5-10 seconds before extracting the entire
fan tray. This will allow the fans time to stop spinning, before removing the tray. Serious
injury can occur if you come in contact with the spinning fan blades.
CAUTION: The PA-7050 firewall configured with AC power supplies is capable of
operating from 100 to 240 VAC 50/60 Hz at 27 amps maximum.
WARNING: You must shut off the electric current to the DC feed wires before
connecting or disconnecting the wires from the DC power supply.
