Installing and Connecting the HP 600/610 External Power Supplies
Recommended Connection Topologies
EPS cables
Limitations
EPS ports A1 and A2 share one common internal power supply; ports B1 and
B2 share a second common internal power supply. The maximum power that
can be supplied to each port pair is 408 W. In other words, if both ports in a
pair are connected to PoE switches, then the maximum power that each port
can provide is 204 W; but if only one port in a pair is connected to a PoE switch,
that port can provide up to 408 W.
In the illustration above, the four switches connected to the HP 610 EPS are
limited to 204 W of power on each EPS port. If a switch tries to draw more
than 204 W of power from the HP 610 EPS, an over-current condition occurs
and the EPS port shuts down. To supply more than 204 W on one EPS port,
the other port in the pair must first be disconnected. The maximum power
that can be provided when only one EPS port in a pair is connected to a switch
is 408 W.
Status Indication
The EPS Port Power Status LEDs on the HP 610 EPS indicate if an EPS port
is providing power to the connected device. For example, if four switches are
connected to the HP 610 EPS and the power to the switch on port A1 fails, the
Power Status LED for port A1 turns off, but for ports A2, B1, and B2 it remains
on.
