Planning and
Implementation for the
3500yl Switches
The table in this example configuration contains entries that show the PoE
power available for the 3500yl-24G-PWR when connected to an external power
supply.
Figure 9-2. Example of two 3500yl-24G-PWR Switches connecting to a HP
ProCurve 620 External and Redundant Power Supply (J8696A)
The same considerations apply for the mini-GBIC ports as in the previous
example.
Two 3500yl-24G-PWR switches or two 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.
