Power Connector

The Switch 4000M and 8000M does not have a power switch; it is powered on
when connected to an active AC power source. The switch automatically
adjusts 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 4000M/
8000M Power Supply, HP J4119A) can be installed in the back of the switch.
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 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.
