ENERAL OWER
Danger:
• Only a qualified electrician should connect power cables.
• Before working on equipment that is connected to power, remove jewelry, (rings, necklaces,
watches, etc.). When metal objects are in contact with power and ground, serious burns can occur
or the objects can be welded to the terminals.
• Turn off power at the power source before you install or remove power cords.
• You must use cables that meet local electrical code requirements.
• AC power cord set supplied with this product is strictly restricted for use with this product only.
The AC power cord set must not be used for any other purposes or any other products. When
applying power to the chassis, be sure to use the supplied AC power cord set, and make sure that
you do not use any other product's AC power cord set.
Japanese note:
• Make your ground connections first.
Warning:
• Do not install equipment that appears to be damaged.
• Blank panels and faceplates are required in all empty card and component slots to prevent excess
dust accumulation and to help control airflow and electromagnetic interference. Faceplate blanks
do not have board components or connector pins.
• Electrostatic discharge (ESD) damage can occur if components are mishandled. Always wear an
ESD-preventive wrist or ankle strap and always connect an ESD strap to the grounding plug on the
front of the chassis.
Notes:
• The 7450 ESS-7 requires a minimum of one DC PEM or one AC PSM and one AC PEM to
operate. Additional power units are recommended for redundancy.
• For full redundancy, each PEM should be attached to an independent power source with a
dedicated circuit breaker.
• In the event of a power module failure, the entire power module must be replaced. There are no
field serviceable parts inside the modules.
