The table in this example configuration contains entries that show the PoE
power available for the 3500yl-48G-PWR.
Figure 9-4. Example of two 3500yl-48G-PWR Switches connecting to a HP
ProCurve 620 External and Redundant Power Supply (J8696A)
Each of the two switches can receive full redundant power from the 620 RPS/
EPS should one of the switches internal power supplies fail. The lowest loaded
bank of ports (1-24 or 25-48) has 22 watts reserved. That power is available
for use by the two highest priority ports in the bank, (in a default configuration
ports 1 and 2, or 25 and 26).
