Connecting an external PoE power supply
CAUTION:
To ensure steady operation of the switch, when you use your own PoE power cord, make sure the cross
section of the cable is no less than 8.4 mm
2
(0.01 in
2
) and the power cord can carry 50 A current.
To supply PoE power to 7502 or 7503-S, a PoE power cord is required to connect the external PoE power
supply to the PoE input on the chassis rear panel. You can use an A-RPS800 or other DC power supplies
that can satisfy PoE input requirements: voltage range –46 V to –57 V (–52 V to –57 V for type 2) and
maximum current 40 A, as the external PoE power supply.
If you use an A-RPS800 as the external PoE power supply, HP recommends that you order the HP X290
14-pin Mini-Fit to 2 x OT Copper Lug 1m RPS Power Cable (JG332A). For more information about the
cable, see "Appendix B FRUs and compatibility matrixes."
Connecting the A-RPS 800 to the switch
1. Remove the blank panel covering the PoE port of the switch.
2. Connect the OT terminal (with a – sign) on the blue wire to the NEG(–) terminal on the PoE power
supply socket, and fasten the captive screw. Connect the OT terminal (with a + sign) on the black
wire to the RTN(+) terminal on the PoE power supply socket, and fasten the captive screw.
3. Install the blank panel to the PoE port.
4. Connect the PoE power cord to the A-RPS 800: Plug the H2*7 of the PoE power cord into the DC
output of the A-RPS 800, and then fasten the screw, as shown in callout 5 on Figure 31.
5. Supply power
to the A-RPS 800: Plug the female end of the AC power cord into the AC input on
the A-RPS 800 and ensure a good contact, and plug the male end of the AC power cord into the
external power supply socket.
