ProCurve 3500yl-48G-PWR Configuration
PoE power requirements are figured differently for the 3500yl-48G-PWR
switch, see PoE Power on page 2-4. The table in this example configuration
contains entries that show the PoE power available for the 3500yl-48G-PWR
switch.
In the default configuration PoE power priority is determined by port number,
with the lowest numbered port (port 1) having the highest priority, and the
highest numbered port (port 48) having the lowest priority.
Note It is the ports configured with the highest priority of either bank (1-24 or 25-
48) that will receive PoE power first. For example, if the highest priority ports
have been re-configured to be 23, 24 and 47, 48, then they will receive PoE
power before the lower priority ports.
Figure 3-3. Example of a 3500yl-48G-PWR Switch
■ 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).
All 25 ports can receive up to 15.4
watts of PoE power
or
48 ports can receive up to 7.0
watts of PoE power
