Implementation for the 3500
Switches
The table in this example configuration shows the PoE power available for
the HP ProCurve 3500-24-PoE switch when configured with an external power
supply.
Figure 8-2. Example of two HP ProCurve 3500-24-PoE Switches connecting to an
HP ProCurve 620 External and Redundant Power Supply (J8696A)
The same considerations apply for the mini-GBIC ports as in the previous
example.
Two HP ProCurve 3500-24-PoE switches can be supported by one 620 RPS/
EPS. This is a full redundant configuration—both of the switches can be
supplied with power should either of their internal power supplies fail. The
620 RPS/EPS can supply system power to keep the switch powered on and
PoE power to supply the attached PoE devices with power.
