| 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. |
|
|
C a u t i o n | 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. |

1.Ensure the AC power supply is not plugged into an AC power source on the failed power supply.
