Questions about this item

Does the HPE JL819A 4000i PoE power supply include the DIN rail mounting hardware or must that be purchased separately?

The unit is a DIN form-factor power supply designed to clip onto a standard DIN rail; mounting hardware for the rail itself is not included and must be sourced separately.

Should I choose the 240 W 54 VDC model or is there a different capacity version of the JL819A for higher PoE budgets?

The JL819A is offered as a single 240 W 54 VDC configuration; no other wattage or voltage variant exists under this part number.
