* The Maximum Power Level Output levels reflect the loss introduced by a 100
meter Ethernet cable between the Power Source Equipment (PSE) and the
Power Device (PD).
A port connected to a network node that is not a PD functions as a regular
Ethernet port, without PoE+. The PoE+ feature remains enabled on the
port but no power is delivered to the device.
Note
On the 24 port x610 PoE+ switches, the PoE+ power supplied from
ports 21R, 22R, 23R and 24R is unaffected by insertion of a SFP
module into the corresponding SFP combo port.
On the 48 port x610 PoE+ switches, the PoE+ power supplied from
ports 47R and 48R is unaffected by insertion of a SFP module into
the corresponding SFP combo port.
Power Capacity
Either a 250W (AT-PWR250), 800W (AT-PWR800) or a 1200W
(AT-PWR1200) power supply can be installed in the x610-24Ts-POE+,
x610-24Ts/X-POE+, x610-48Ts-POE+ and x610-48Ts/X-POE+ switches.
The power supply model that is installed determines the maximum number
of PoE+ ports that are supported on the switch. The following three tables
show the maximum number of PoE+ and PoE ports supported on the
switch, depending on the model of power supply installed. Note that the
numbers in these tables only provide the maximum number of PoE+ and
PoE ports supported and that there are many combinations of PoE+ and
PoE ports that are supported.
