MS450-12-HW is a managed Cisco Meraki MS450 Layer 3 aggregation switch built for high-bandwidth fiber handoff rather than copper endpoint access. It provides twelve 40GbE QSFP+ fixed switching ports for downstream aggregation links and two fixed 100GbE QSFP28 uplink ports for northbound connectivity. The platform is Non-PoE, uses a 1U rack-mount chassis, and belongs to the Cisco Meraki MS450 series. Meraki Dashboard management gives network teams cloud-based configuration and monitoring for the switch, while the hardware design keeps access-layer PoE delivery on downstream switches and concentrates higher-speed fiber traffic at the aggregation layer. The 100GbE QSFP28 uplinks are rated for 100Gbps use cases only, so uplink planning should use the correct 100G optics or cables rather than treating those ports as downshifted 40G interfaces. The fixed-port layout separates aggregation links, uplinks, and the dedicated RJ45 management path.
1.36 Tbps switching capacity delivers the backplane headroom required when multiple 40G fiber links converge before moving into a 100G core path. 1011.8 Mpps forwarding rate gives a calculated line-rate reference for packet handling across the documented switching fabric. OSPF routing supports routed aggregation designs, while Layer 3 switching, IPv4 and IPv6 ACLs, 802.1Q VLAN tagging, DHCP snooping, Dynamic ARP Inspection, 802.1X authentication, and broadcast storm control provide campus control-plane coverage. MS450-12-HW also includes a dedicated RJ45 management interface for local status access and Dashboard reachability. Warm spare capability uses VRRP for redundant gateway designs, and MAC forwarding capacity reaches 80000 entries. 138W maximum power consumption helps size rack power circuits for the aggregation layer, and 250W AC supply support aligns the chassis with standard data-room feeds. Automatic firmware upgrades, remote packet capture, SNMP integration, and syslog integration keep operational telemetry and maintenance tasks inside the Meraki cloud-managed workflow.
In deployment, MS450-12-HW sits at the enterprise core or aggregation tier, collecting fiber uplinks from compatible Meraki MS355 access and distribution switches, server access switches, or other 40G-capable infrastructure. Two dedicated 100G stack ports provide physical stacking with up to 400 Gbps stack bandwidth, and the 1U chassis fits standard rack rows without consuming extra vertical space. ORM Systems supplies this switch new and certified refurbished; refurbished units are checked for QSFP+ and QSFP28 port recognition, fan status, power supply health, and cloud-management readiness before dispatch. Request a quote for the required condition, license term, regional power cord, optics, stack accessories, and warranty preference. Power cords are ordered by region, so UK and international orders include the correct cable set with the switching hardware. Enterprise and volume buyers receive support for matched quantities, staged rollouts, and procurement bundles built around high-bandwidth Meraki aggregation projects.

MS450-12-HW sits at the aggregation layer and terminates 40G QSFP+ fiber uplinks from downstream Meraki MS355 or distribution blocks across its twelve 40GbE ports. Engineers place routed VLAN interfaces, OSPF adjacencies, ACLs, and warm spare design at this tier, then forward northbound traffic through the two 100GbE QSFP28 uplinks. The dedicated management interface separates Dashboard reachability from data-plane optics. The result is a 40G aggregation block that clears access-layer bandwidth into 100G core links without shifting the design into copper access switching.
Two MS450-12-HW switches form a hardware stack through dedicated 100G stack ports, providing up to 400 Gbps stack bandwidth while preserving the 12 40GbE QSFP+ front-panel ports per chassis for aggregation links. Network teams cable stack members, power supplies, fans, optics, and upstream 100G paths as one aggregation domain in Meraki Dashboard. OSPF, VLAN interfaces, ACLs, and warm spare decisions stay aligned across the block. The result is denser aggregation capacity with consistent failover behaviour and fewer independent switch control points.
MS450-12-HW operates as the high-bandwidth Meraki Dashboard control point for fiber aggregation. Dashboard stores the MS450-12 port configuration, Layer 3 routing, stack membership, firmware schedule, alerts, packet capture access, SNMP, and syslog settings while the hardware moves 40G and 100G traffic in the rack. Engineers use the local status page only for reachability tasks such as static IP setup before cloud check-in. The result is centralised operational control over aggregation links, routed services, troubleshooting data, support reviews, and planned maintenance windows.

MS450-12-HW is a Cisco Meraki MS450-12 Layer 3 aggregation switch for high-bandwidth campus and data centre aggregation roles. It provides 12 40GbE QSFP+ fiber ports, two 100GbE QSFP28 uplink ports, two 100G hardware stack ports, Meraki Dashboard cloud management, and a 1U rack-mountable chassis for dense fiber switching.
MS450 identifies the Cisco Meraki MS450 aggregation switch series, 12 indicates the 12 primary 40GbE QSFP+ switching ports, and HW identifies the hardware appliance SKU. The full MS450-12-HW part number refers to the Meraki MS450 12x40G aggregation switch hardware, excluding region-specific power cords and Meraki licensing.
MS450-12-HW is a cloud-managed fiber aggregation switch, not an access switch, router, firewall, or optical transceiver. It concentrates high-speed downlinks from access, distribution, or server-facing switches and presents 100GbE QSFP28 uplinks northbound. The design also includes hot-swappable power supplies, hot-swappable fans, and a dedicated RJ45 management interface.
MS450-12-HW sits at the high-bandwidth aggregation layer of the Cisco Meraki MS switching portfolio. Cisco positions the MS450-12 above lower-speed aggregation models such as MS410 and MS425, and alongside high-performance access switches such as MS355. Its role is 40G fiber aggregation with 100G uplink capacity under Meraki cloud management.
MS450-12-HW includes 12 40GbE QSFP+ fiber switching ports, two 100GbE QSFP28 fiber uplink ports, two 100G hardware stack ports, and one dedicated RJ45 management interface. The front-panel 40G ports aggregate fiber links from downstream switches, while the 100G QSFP28 ports handle higher-speed uplinks toward the core or adjacent aggregation layer.
MS450-12-HW provides 1.36 Tbps maximum switching capacity according to Cisco Meraki specifications. That capacity aligns with the 12 40GbE QSFP+ switching ports and two 100GbE QSFP28 uplinks on the MS450-12 platform. The specification suits aggregation designs that consolidate many high-speed fiber links without dropping into 10G-only switching tiers.
MS450-12-HW does not support PoE or UPoE because it is a fiber aggregation switch, not a copper endpoint access switch. Cisco Meraki lists UPoE capability as No for MS450-12. Powered endpoint connections should terminate on compatible access switches such as Meraki MS355 models, then uplink into the MS450-12-HW over 40G fiber.
MS450-12-HW supports Layer 3 switching, including OSPF, warm spare redundancy with VRRP, DHCP server, DHCP relay, IPv4 and IPv6 ACLs, and related campus switching controls. These features place routed aggregation, VLAN gateway placement, and upstream failover inside the Meraki Dashboard operating model rather than a standalone CLI-only switch workflow.
MS450-12-HW is managed through Cisco Meraki Dashboard. The platform provides cloud-based configuration, email alerts, remote troubleshooting tools, remote packet capture, per-port and per-client visibility, SNMP or syslog integration, and user-scheduled firmware updates. Initial deployment requires claiming the device to a Dashboard organization and adding it to the intended Dashboard network.
MS450-12-HW supports hardware stacking through two dedicated 100G stack ports and provides up to 400 Gbps stacking bandwidth. Cisco Meraki documentation also lists stack creation as part of the Dashboard configuration workflow. Stacking cables are not included with the MS450 series package and should be ordered separately when a physical stack is planned.
MS450-12-HW is used for high-speed fiber aggregation where multiple downstream switches need 40G connectivity and the upstream network requires 100G handoff. It typically concentrates traffic from access or distribution blocks, applies Layer 3 routing where required, and keeps switch visibility inside Meraki Dashboard for operational monitoring, firmware control, and troubleshooting.
MS450-12-HW suits networks that have outgrown 10G-only aggregation and need 40G fiber downlinks with 100G uplinks. The 1.36 Tbps switching capacity, 12 QSFP+ ports, and 400 Gbps stacking bandwidth fit larger campus aggregation, data centre aggregation, and high-density distribution environments where Meraki cloud operations are already standardised.
MS450-12-HW fits workloads that drive sustained east-west or north-south bandwidth across fiber switching layers, including virtualised server access, high-density access aggregation, storage-adjacent network paths, and multi-gigabit campus uplinks. The 40G QSFP+ port set and 100G QSFP28 uplinks make it appropriate when 10G uplink aggregation becomes a bottleneck.
MS450-12-HW works in Meraki campus deployments where downstream MS access or distribution switches report into the same Dashboard ecosystem. Cisco notes that MS450 works best alongside MS355. In that role, MS355 switches provide access or distribution connectivity while MS450-12-HW aggregates 40G fiber and forwards northbound traffic over 100G uplinks.
MS450-12-HW pairs well with Cisco Meraki MS355-24X and MS355-24X2 switches because Cisco compares those models directly with MS450-12 for campus uplink designs. MS355 models provide multigigabit access and 40G uplinks, while MS450-12-HW supplies 12 40G QSFP+ aggregation ports, two 100G QSFP28 uplinks, and 400 Gbps stacking bandwidth.
MS450-12-HW integrates with the Cisco Meraki Dashboard ecosystem. Dashboard handles claiming, network assignment, switch port configuration, stack creation, Layer 3 routing configuration, firmware scheduling, alerts, per-port visibility, and remote packet capture. This makes the SKU suitable for Meraki organisations that standardise monitoring and configuration across switching, wireless, and security appliances.
MS450-12-HW supports common enterprise switching protocols and controls, including 802.1Q VLAN tagging, 802.1X authentication, OSPF, VRRP warm spare operation, DHCP snooping, Dynamic ARP Inspection, broadcast storm control, SNMP, syslog, IPv4 ACLs, and IPv6 ACLs. These integrations matter when the aggregation switch participates in routed campus and policy-controlled switching designs.
MS450-12-HW uses QSFP+ interfaces for its 12 40GbE switching ports and QSFP28 interfaces for its two 100GbE uplink ports and two 100G hardware stack ports. Buyers should match Cisco Meraki-supported optics, direct attach cables, fiber type, and reach to the port speed and link design before ordering transceivers or stack accessories.
MS450-12-HW is the stronger aggregation choice when the design needs 12 40G QSFP+ ports and 100G uplinks. MS355-24X is a multigigabit access or distribution switch with 16 1GbE RJ45 ports, eight mGbE RJ45 ports, four 10G SFP+ uplinks, and two 40G QSFP+ uplinks. The MS450-12-HW focuses on fiber aggregation rather than powered access.
MS450-12-HW provides higher aggregation density with 12 40G QSFP+ ports and two 100G QSFP28 uplinks. MS355-24X2 provides 24 mGbE RJ45 access ports, four 10G SFP+ uplinks, two 40G QSFP+ uplinks, UPoE capability, and the same 400 Gbps maximum stacking bandwidth. The choice depends on fiber aggregation versus powered multigigabit access.
MS450-12-HW targets higher-speed aggregation with 12 40G QSFP+ ports and two 100G QSFP28 uplinks. MS425-32 is a Meraki aggregation switch built around 32 10G SFP+ ports and two 40G QSFP+ uplinks. MS425-32 fits dense 10G aggregation, while MS450-12-HW fits designs moving aggregation links to 40G and uplinks to 100G.
Cisco's end-of-sale bulletin lists C9500-32QC as the migration product part number for MS450-12-HW. That does not make the Catalyst 9500 a like-for-like Meraki Dashboard replacement because Catalyst and Meraki switches use different operating and management models. It does identify the Cisco aggregation tier suggested for migration planning after MS450-12-HW end-of-sale milestones.
MS450-12-HW availability depends on channel supply because Cisco announced end-of-sale dates for the Meraki MS450 12x40G aggregation switch. ORM Systems may quote new, surplus, or refurbished units when supply is available. Buyers should treat condition, accessories, licensing, and lead time as quote-specific details rather than assumptions from the part number alone.
MS450-12-HW pricing is normally quote-based because condition, market supply, licensing requirements, power cords, optics, stacking accessories, warranty length, and order quantity affect the final commercial offer. The safest buying workflow is to request a current ORM Systems quote for the exact MS450-12-HW hardware condition and accessory bundle required.
Cisco announced end-of-sale and end-of-life milestones for MS450-12-HW. The Cisco bulletin lists October 29, 2026 as the last date to order through Cisco point-of-sale mechanisms and October 31, 2031 as the last date of support for eligible coverage. Availability after end-of-sale depends on channel, refresh, and refurbished supply.
MS450-12-HW lead time depends on current new, surplus, refurbished, or Cisco Refresh availability, plus the required power cord, license, optics, and stacking accessories. End-of-sale status makes lead time more supply-sensitive than active run-rate switching SKUs. ORM Systems quotes should identify dispatch expectations, condition, and any accessory dependencies before purchase.
Bulk pricing for MS450-12-HW is most practical when buyers specify the required quantity, condition preference, warranty term, Meraki license term, power cord region, optics, and stack accessories at the quote stage. Aggregation switch projects often need matched units or stack pairs, so volume pricing should be requested with the full bill of materials.
ORM Systems warranty coverage for MS450-12-HW should be confirmed on the quote because warranty length varies by condition, source, and commercial offer. The SKU is commonly evaluated as new, surplus, or refurbished hardware, and the warranty should cover the switch chassis supplied in the order. Cisco licensing and Cisco support coverage remain separate considerations.
Refurbished MS450-12-HW units should be tested for power-on health, fan status, power supply status, port recognition, management access, Dashboard claim readiness, and physical condition before dispatch. For this SKU, testing should pay particular attention to the 12 QSFP+ ports, two QSFP28 uplinks, dedicated stack ports, fans, and power supply configuration.
MS450-12-HW deployments should align with Cisco Meraki installation guidance, enterprise switching standards, and local electrical safety requirements. The switch supports 802.1Q VLAN tagging, 802.1X authentication, IPv4 and IPv6 ACLs, SNMP, syslog, and DHCP snooping. Cisco also states that equipment should be installed in a restricted access location by trained service personnel.
MS450-12-HW first-use configuration starts by claiming the device into a Cisco Meraki Dashboard organisation, adding it to a Dashboard network, connecting it to local infrastructure for cloud check-in, and allowing initial firmware updates. Configuration then continues in Dashboard for switch stacks, local VLANs, port settings, and Layer 3 routing.
MS450-12-HW requires the appropriate Cisco Meraki switch license for Dashboard management and support operation. The hardware SKU identifies the physical aggregation switch, while license SKUs are ordered separately by term. Buyers should align the license term with the deployment plan and confirm whether the quoted ORM Systems bundle includes hardware only or hardware plus licensing.
MS450-12-HW orders should account for region-specific power cords, compatible QSFP+ optics or cables for 40G links, QSFP28 optics or cables for 100G uplinks, and stacking cables where a hardware stack is required. Cisco Meraki notes that stacking cables are sold separately and that region-specific power cords are not included in the box.
MS450-12-HW can be sourced in the UK through ORM Systems as a Cisco Meraki aggregation switch quote. UK buyers should request the hardware condition, warranty term, power cord option such as MA-PWR-CORD-UK, license requirement, optics, stacking cables, and expected dispatch timing in the same enquiry to avoid incomplete switch orders.
ORM Systems can quote MS450-12-HW for international buyers subject to supply, export checks, courier availability, and destination requirements. International orders should specify destination country, required power cord region, licensing needs, optics, stack accessories, warranty expectations, and preferred delivery terms so the quote reflects the complete Meraki aggregation switch deployment package.
