Connecting an external PoE power supply
CAUTION:
•
To avoid damage to the switch, make sure you connect the negative ends of the power cords to negative
terminals and positive ends to positive terminals.
•
To ensure steady operation of the switch, make sure the cross section of the cable is not less than 8.4 mm
2
(0.01 in
2
) and the power cord can carry 50 A current.
This section uses the A-RPS800(JD183A) as an example. As a best practice, order the power cord
for the A-RPS800 from Hewlett Packard Enterprise.
