620 RPS/EPS
The 620 RPS/EPS can provide backup power support for up to two HP
ProCurve switches. In the illustration below, two HP ProCurve 3500yl-24G-
PWR switches are connected to the RPS ports on a 620 RPS/EPS.
Figure 2-15. Connecting RPS to two 24-port switches
The 620 RPS/EPS is designed to provide primary or backup power to up to
two HP ProCurve PoE switches. In the following illustration, two HP ProCurve
3500yl-24G-PWR switches are being supplied with external PoE power from
an 620 RPS/EPS. The switches provide PoE power to Ethernet devices
connected to their ports.
