Power Connector
The Series 4100GL Switches 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 (HP Procurve Switch GL/XL
RPS, HP J4839A) can be installed in the back of the Series 4100GL switches.
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.
Caution The switch power supplies are 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.
