Power Connector

The Switch 4200vl Series do not have a power switch; they are powered on
when connected to an active AC power source. The switches automatically
adjust to any voltage between 100-127 and 200-240 volts and either 50 or 60
Hz. There are no voltage range settings required.

Slot for Redundant Power Supply

A second, load-sharing redundant power supply (ProCurve switch RPS,
J4839A) can be installed in the back of the Switch 4200vl Series. To provide
true redundancy, this second power supply should be connected to a different
AC power source from the other supply. Then, if one AC power source fails,
the switch will continue to run.
C a u t i o n
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.
Because the switch can run on a single supply, removing a redundant supply
will not interrupt switch operation.
