Cisco Meraki MX250 Firewalls - Refurbished, Used, New

Best Selling

The Cisco Meraki MX250 is a rack-mount security appliance for large branch offices and campus edges: a cloud-managed firewall with SD-WAN, AutoVPN site-to-site tunnels, content filtering and intrusion prevention, all configured from the Meraki Dashboard. It is the step up from the MX105 and sits below the MX450 in the same chassis family. NetworkTigers sells MX250-HW appliances, MA-PWR-250WAC power supplies and MA-FAN-18K fan modules refurbished, used and new. Every unit is tested before it ships so it works when it arrives, and every MX250 ships unclaimed, ready for your own Dashboard organization.

Which MX250 configuration do I need?

Choose the MX250 when a site has outgrown the MX105, usually because it needs 10G SFP+ ports on both the WAN and LAN side, or because it will terminate AutoVPN tunnels from many branches. If the site is a headquarters concentrating hundreds of tunnels, look at the MX450 instead; the MX250 and MX450 share the same port layout, power supply and fan, so the choice is about capacity rather than cabling. Decide on power redundancy before you order: the chassis takes two MA-PWR-250WAC supplies, and each listing states how many are installed. The same applies to the MA-FAN-18K modules. For high availability, buy a matched pair and run one as a warm spare; both units then need their own Meraki license, sold separately. Use 10G SFP+ optics or direct attach cables for the uplinks and 1G SFP or RJ45 for everything else.

Frequently asked questions

What does unclaimed mean on an MX250 listing?
The serial number is not attached to any other organization's Meraki Dashboard, so you can claim it into your own organization and network on arrival. NetworkTigers checks claim status before a unit is listed.

Can an MX250 be a warm spare for an MX450?
No. Meraki warm spare pairs must be the same model. Pair an MX250 with an MX250.

Do the power supplies and fans swap without downtime?
Yes. The MA-PWR-250WAC and MA-FAN-18K are hot-swappable modules that slide out of the rear of the chassis, so a failed one can be replaced while the appliance stays in service on its second supply.

NetworkTigers has sold enterprise network equipment since 1996. Every appliance, power supply and fan carries the NetworkTigers 365-day warranty. Need a redundant pair with spare power? Ask us for a quote.
