Cisco Meraki PWR-MS320-250WAC 250W AC Hot-Swap Switch Power Supply (Delta DPS-250AB-86 B)

Field-replaceable 250W module for Meraki MS switches. 100-240V universal input • +12V at 20.83A • AC OK and PS OK status LEDs • Cord retention bail • Hot-swappable.

Condition: Used, pulled from service. This module ran its entire service life in a colocation data center rack on 208V conditioned power. Air-conditioned facility, clean redundant feed, never relocated, never shipped between sites, never in a field cabinet or a vehicle. For a switching supply with a fan in it, that is about the easiest life the part can have, and it is a very different proposition from a unit pulled out of a closet or a warehouse. Cosmetic wear on the sheet metal is consistent with rack service and is shown honestly in the photos. What It Is

This is the hot-swappable 250 watt AC power module used in Cisco Meraki MS-series switches. It slides into the switch's power bay, latches, and can be pulled and replaced without powering down the switch when the chassis has a second supply installed.

• Replace a failed supply without replacing a whole switch, which is the entire reason these are modular.
• Add a second supply for redundancy on a switch currently running one, so a PSU failure stops being an outage.
• Keep a cold spare on the shelf. Anyone running Meraki in production knows the value of having the part in hand instead of waiting on an RMA.

Built by Delta Electronics, model DPS-250AB-86 B. Delta is the OEM behind a very large share of enterprise switching and server supplies, and this is the genuine Cisco-branded module rather than a third-party equivalent.

• 1 × Cisco Meraki PWR-MS320-250WAC 250W power supply module

Module only. No power cord, no switch, no blanking panel and no rails. Any standard C13 to 5-15P or C13 to C14 cord works.

Why This One

• Data center provenance, which almost no used PSU listing can offer. Racked in conditioned air on 208V clean power its whole life. Not a shelf-pull of unknown history, and not something that baked in a hot closet.
• 208V is the easy life for a supply like this. Switching supplies run cooler and more efficiently at the higher input voltage, which means less thermal stress on the capacitors over years of service.
• Genuine Cisco Meraki module, made by Delta. Correct PID, correct part number, correct connector. It seats and latches the way the switch expects.
• Redundancy is cheap insurance. If your MS switch is running a single supply today, adding a second one costs a fraction of what an unplanned outage costs.
• Universal 100 to 240V input. Works on standard 120V wall power or a 208/240V rack PDU with no configuration.
• Front panel status LEDs. AC OK and PS OK tell you at a glance whether the module or the feed is the problem, without pulling anything.

Before You Buy

• Confirm your switch takes this module. The PID is PWR-MS320-250WAC. Meraki also shipped 640W and 1025W variants in the same form factor, and PoE-capable switches generally need the higher wattage units. Check what your chassis is specified for before ordering.
• This is the 250W non-PoE class supply. If you are powering a switch full of PoE devices, this is likely not enough. The 640W or 1025W modules exist for that reason.
• No power cord included. Standard C13 cord, easy to source, and you very likely already have one.
• Used and sold as-is. Pulled from a working data center deployment. Please review the photos and ask any questions before purchasing, as this listing does not accept returns.
• Cosmetic wear present. Rack-service scuffing on the sheet metal. It is a power supply that lived in a switch, not a display piece.
