Introducing the ProCurve Series 5400zl Switches Introducing the ProCurve Series 5400zl Switches Back of the Switch Caution Power Connector The Series 5400zl Switches do not have a power switch; they are powered on when connected to an active AC power source. The Series 5400zl Switches automatically adjust to any voltage between 100-127 and 200-240 volts when using the J8712A power supply, and 200-240 volts only when using the J8713A power supply, and either 50 or 60 Hz.There are no voltage range settings required. Redundant Power Supply Load-sharing redundant power supplies (ProCurve Switch zl 875 W Power Supply, J8712A or a ProCurve Switch zl 1500 W Power Supply J8713A) can be installed in the back of the Series 5400zl Switches. To provide redundancy, each power supply should be connected to different AC power sources. Then, if one AC power source fails, the switch will continue to run. The switch redundant power supply is hot swappable, but, as indicated by the caution statement on the power supply, it must be disconnected from AC power before being installed or removed. CAUTION: .Refer to the installation guide for proper power cord selection .Disconnect AC power from the power supply BEFORE installing or removing the supply. Otherwise, damage to the. equipment may result. Because the switch can run on a single supply, removing a redundant supply will not interrupt switch operation. However, on the 5412zl one power supply will only supply enough power to run the module slots A-F. Slots G-L will not receive any power unless there are at least two power supplies installed.
