Switch Ports - NEC PF5820 Installation Manual

AC power supply
PF5820 has two hot-swap redundant 450 W ac power supplies. Each internal
power supply has an individual IEC 320 power connector on the rear panel. The
power cord attaches to a universal grounded ac power source. You can replace a
hot-swap power supply module without powering off the switch or disrupting switch
functions.
DANGER
An electrical outlet that is not correctly wired could place hazardous
voltage on the metal parts of the system or the devices that attach to the
system. It is the responsibility of the customer to ensure that the outlet is
correctly wired and grounded to prevent an electrical shock. (D004)
Each power supply can be connected to a separate ac circuit to mitigate the risk of
down time during a power failure. When used in a redundant configuration, the dual
power supplies have a load-sharing capability that enables each power supply to
operate at approximately 50% of full load. Using redundant power can minimize the
power disruption during a power supply failure and extend the expected lifetime of
each power supply by operating normally in a conservative power mode.
There is no power switch on PF5820; the switch unit powers up when power is
supplied through the power cords.
The Power Supply LED indicates the status of the power supplies. The LED flashes
when only one power cord is connected, and is steady when both power cords are
connected.
