Cisco Meraki MA-PWR-1000WAC MS390 341-101208-01 DPS-1000AB-5 C Power Supply

This listing is for the 1000W AC power supply with the Cisco part 341-101208-01 and the Delta model DPS-1000AB-5 C on its label, sold for Meraki MS390 switches. Rated output is 54V at up to 18.5A, and it is a hot-swap supply for the MS390 power supply bays.

The MS390 takes two power supplies. A second supply gives redundancy, so the switch keeps running and keeps powering PoE devices if one supply fails, and on PoE models it adds capacity to the PoE budget. Fit the two supplies to separate circuits or UPS units where possible.

Meraki's MS390 data sheet lists the MA-PWR-350WAC, MA-PWR-715WAC, and MA-PWR-1100WAC as its power supplies. Check the label on the supply in your switch and compare the 341 part number before ordering, so the replacement matches what is installed. This listing is for one power supply. A failed supply shows in the Meraki Dashboard, so a spare can be swapped in as soon as the alert appears.

Switches that take this supply include the MS390-48P-HW 48-port PoE+ switch. For the Meraki-listed high-wattage option, see the MA-PWR-1100WAC 1100W power supply.

This seller refurbished Cisco Meraki MA-PWR-1000WAC power supply is tested, working, and covered by the NetworkTigers one-year warranty.
