Replacing Power Supplies
If your ProCurve 8200zl Switch is configured with redundant power supplies,
you will not suffer any loss of traffic or performance if a power supply fails.
Replace the failed component as soon as possible. One of the Internal Power
LEDs on the management module will blink simultaneously with the switch
Fault LED indicating which power supply failed.
Caution The Series 8200zl switch is designed to provide continuously operating PoE
power in the event of a single power supply failure with only a loss of PoE
power to lower priority ports.
If more than one power supply fails while the switch is at or near maximum
operating power (that is: the sum total of all PoE supply capacity minus the
largest supply, see chapter 2 and 4 of the ProCurve Power over Ethernet (PoE)
for zl and yl Products), loss of all PoE power may result.
To return PoE power to the ports, without causing the switch to reboot, when
there are two or more power supplies still supplying 12V power, unplug the
power cord for 5 seconds and replug it for each power supply one at a time.
To remove an AC power supply:
1. Ensure the AC power supply is not plugged into an AC power source on
the failed power supply.
