Cisco Meraki MX450 Firewalls - Refurbished, Used, New

Best Selling

The Cisco Meraki MX450 is the largest appliance in the Meraki MX firewall line, built for enterprise headquarters, campus cores and data center edges that concentrate AutoVPN tunnels from many branches. It is cloud managed from the Meraki Dashboard and combines a stateful firewall, SD-WAN, intrusion prevention and content filtering in one 1U chassis with 10G SFP+ interfaces. NetworkTigers sells MX450-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 MX450 ships unclaimed, ready to be claimed into your own Dashboard organization.

Which MX450 setup do I need?

The MX450 is the right choice when one site is the hub for the whole organization: it terminates the AutoVPN tunnels from every branch, so its capacity sets the ceiling for the SD-WAN as a whole. If the site is a large branch rather than the hub, the MX250 has the identical port layout at lower cost. Most buyers run the MX450 in pairs for high availability, with the second unit configured as a warm spare on the same LAN, and keep a spare MA-PWR-250WAC and MA-FAN-18K on hand because the same modules fit both the MX450 and MX250. Each listing states how many power supplies and fans are installed; order a second supply if you want dual-feed power. Plan the uplinks around 10G SFP+ optics or direct attach cables, and use the 1G SFP and RJ45 ports for downstream switches, servers and management. Every appliance needs a Meraki license, which is sold separately.

Frequently asked questions

Is a used MX450 safe to put at the center of a network?
Yes. Each unit is powered up, checked in the Dashboard and tested through its ports before it ships, and it carries the same 365-day warranty as a new unit.

Can I run two MX450s in an active-active pair?
No. Meraki high availability for the MX is active-passive: one appliance forwards traffic and the warm spare takes over if it fails. Both units sit on the same LAN segment and both need their own Dashboard registration.

Do the SFP+ ports need Meraki-branded optics?
Meraki publishes compatibility for its own Meraki-labeled transceivers and direct attach cables, and those are what the Dashboard recognizes without a warning. Tell us the port speed, fiber type and distance for each link and we will match optics from our Meraki range.
