Hi Ruby,
Here is the required items in USD cost and please use the below model for the PoE edge switches which have more PoE output.
0235A1E8 LS-5130-28S-HPWR-EI H3C S5130-28S-HPWR-EI L2 Ethernet Switch with 24*10/100/1000BASE-T Ports and 4*1G/10G BASE-X SFP Plus Ports,(PoE+,AC/DC)
As the unit cost is higher, so I have provided a special discount to you as don't want to increase your total cost.
