Here are the power supply requirements for the AT-IS130-6GP switch:
48V, 2.5A (per port 15W) (+18.75%/-6.25%)

OR
54V, 2A (per port 30W) (+5.55%/-5.55%)
48V, 2.5A (par port 15W) (+18.75%/-6.25%)
OU
54V, 2A (par port 30W) (+5.55%/-5.55%)
The DC power supply must be capable of supplying the above

current continuously over the operating temperature range of
-40° C to 75° C (-40° F to 167° F).
L'alimentation CC doit être capable de fournir 7A en continu dans
la plage de températures de fonctionnement de
-40° C à 75° C (-40° F à 167° F).
A single power supply that meets the above requirements can fully power
the switch. A second power supply can also be connected for power
redundancy.
Power supplies are connected to four of the six terminals on the
power/alarm connector on the top panel of the chassis. Refer to
Figure 7.
Each power supply is connected to the switch with two wires, one positive
(+) and one negative (-). If you are installing only one power supply to the
switch, you may connect it to either the PWR 1 (V1+,V1-) or PWR 2
(V2+,V2-) pins.
Note
See for "Power Connector Pinout Assignments" on page 107 for the
pinout function assignments.
