Connecting An External Poe Power Supply - HP 7500 Series Installation Manual

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
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
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
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.
