A single 2610-24/12PWR switch with a dedicated 600 RPS/EPS unit has fully
redundant PoE power for the 12 PoE ports at 7.5 W per port or 12 ports at 15.4
W per port. Only 12 ports can be PoE powered.
■ The internal power supply can provide up to 126 W of power to be used on all
12 PoE ports. The power can be allocated up to the maximum of 12 ports, or
126 W, whichever is depleted first with a reserve of 22 W maintained by the
switch for power management. If more power is needed to allow the
maximum of 15.4 W on all 12 ports, an external power supply accessory is
needed.
■ Also (not shown), two 2610-24/12PWR switches with a dedicated 600 RPS/
EPS unit has full redundant PoE power for both switches. The 600 RPS/EPS
supplies 408 watts to one switch and 204 watts to each switch when two
switches are connected to the 600 RPS/EPS.
