The maximum power figure must be less than the maximum power available
when the switch is powered by the 600 RPS/EPS or the 610 EPS unit, taking
into consideration the number of switches the 600 RPS/EPS or 610 EPS unit
is powering.
N o t e
Full redundancy is achieved by connecting both the RPS and EPS ports of the
2600-PWR Switches to the corresponding ports of a 600 RPS/EPS.
The following examples only show the EPS connections, however, remember
these switches use a single internal power supply which provides two isolated
output voltages for switch and PoE functionality. One supply voltage provides
power for the switch functionality while the isolated voltage provides power
for the PoE functionality. If either voltage fails, the entire power supply shuts
down disconnecting all switch and PoE connections. Therefore it is important
to provide redundancy for each isolated voltage.
ProCurve 2600-8-PWR Configurations
The tables in the example configurations contain entries that show the PoE
power available when the 2600-8-PWR is used alone. When used with the 600
RPS/EPS or 610 EPS unit, PoE power is available to the PoE ports should the
internal PoE power supply fail. Table entries show the PoE power available
when the 600 RPS/EPS or 610 EPS alone provides PoE power.
