Installing and Connecting the HP 600/610 External Power Supplies
Recommended Connection Topologies
Limitations
The HP 600 RPS/EPS can supply power to only one connected and failed
switch at a time. In the illustration above, the switch connected to RPS port 1
has the highest priority and the switch connected to RPS port 6 has the lowest
priority. When multiple switches fail, a switch connected to a higher priority
port always receives power before a switch connected to a lower priority port.
Status Indication
The Power Status LEDs on the HP 600 RPS/EPS indicate if a port can provide
power. For example, if six switches are connected to the HP 600 RPS/EPS and
the power to the switch on port 4 fails, the Power Status LED for port 4 turns
on and for ports 5 and 6 it blinks. The Power Status LEDs for ports 1, 2, and 3
remain off. The blinking Power Status LEDs for ports 5 and 6 indicate that
they are lower priority ports and cannot supply power to the connected
switches. The Power Status LED's are off for ports 1, 2, and 3 because they
have higher priority and if either port requests power, the power will be
removed from port 4 and given to either 1, 2, or 3.
EPS Connections on the HP 600 RPS/EPS
Recommendations
The HP 600 RPS/EPS is designed to provide primary or backup power to up
to two HP PoE switches. In the illustration below, two HP ProCurve Switch
2650-PWR units are being supplied with external PoE power from an
HP 600 RPS/EPS. The switches provide PoE power to Ethernet devices
connected to their ports.
