MS390-48U-HW is a Cisco Meraki MS390 cloud-managed Gigabit Ethernet access switch providing 48 RJ-45 downlink ports and modular 10G/40G uplink bay. 822W of shared PoE++ power supports attached devices, with endpoint allocation constrained by the whole-switch budget. Uplink modules are separate purchase items, and the base switch does not ship with a populated uplink card. Cisco Meraki Dashboard provides centralized setup, inventory and port administration for the MS390 family. Copper access port density should match the site patch-panel design. Plan optics, rack space, software entitlement and device power requirements together before submitting the purchase order.
MS390-48U-HW price for new stock is $1,557.15. MS390-48U-HW refurb price is $651.00. MS390-48U-HW is in stock and available for free next-day delivery. (terms applied)

256 Gbps switching capacity is available for the model’s Ethernet switching workload. 190.48 Mpps forwarding rate applies to the complete MS390 hardware, not to an uplink card. MS390-48U-HW supports OSPF and static routing with Meraki Dashboard management. The 40G uplink speed is available only with a compatible MA-MOD-2X40G module, while MA-MOD-8X10G provides 10G alternatives. An internal supply delivers a maximum 844.9W platform power load under its specified test configuration. The hardware family has 480 Gbps physical stacking bandwidth through dedicated ports, separate from user uplinks. Fan and supply configuration, ventilation, local status access, and dashboard connectivity must be assessed at rack installation. A second supply can increase the available PoE allocation, but the budget in specifications assumes the primary supply.
MS390-48U-HW is available from ORM Systems as new sealed or certified refurbished stock. Refurbished managed switches undergo inspection, power-on and POST, rated-speed port link checks, firmware verification and configuration wipe to factory default. Powered ports have their PoE output tested under load, and optical bay recognition is checked. Request confirmation of physical condition, installed power modules, compatible optics and licensing entitlement before approving the purchase order. ORM offers up to 3-year extended warranty for new hardware and up to 1 year for certified refurbished units; returns are 30 days with terms applying. Purchase orders are accepted, government buyers can use Net-30 terms, and advance-replacement RMA arrangements are available across UK, EU, US and MEA stock channels.

When an existing campus closet is due for a replacement switch, MS390-48U-HW provides 48 physical downlinks with modular 10G/40G uplink bay. The hardware has already crossed its published end-of-sale milestone, which changes the service horizon for a fresh purchase. Verify access port assignments and record the end-of-support date on the replacement plan before ordering.
Where a wiring closet already uses the same Meraki switching family, MS390-48U-HW supplies a dedicated 480 Gbps hardware stacking path independent of the optical uplink interfaces. Physical stack cable compatibility and licensing across the organization must be checked. Confirm the installed members and order any required cables as separate procurement lines.
An endpoint rollout requiring PoE should be checked against the 822W aggregate PoE++ budget on MS390-48U-HW, not merely its 48 access ports. Aggregate the access-point, handset and camera nameplate loads, then account for cable and power design. Specify the PoE schedule and any supply additions on the purchase order.
Support beyond announced end date
MS390-48U-HW has an end-of-support milestone of 28 March 2032. A new deployment requiring Cisco service beyond that date needs a supported current switch family.
Copper access without module dependencies
MS390 uplinks require a separately purchased MA-MOD-2X40G or MA-MOD-8X10G card. A fixed-uplink switch is necessary where no module purchase can be included.

MS390-48U-HW identifies a Cisco Meraki MS390 managed access switch with 48 RJ-45 ports and modular uplinks. The MS390 hardware belongs to the cloud-managed access line. The exact model determines endpoint power budget, copper interface speed and rack configuration. Confirm installed transceivers, entitlement status and power requirements against the exact part number before finalizing the equipment schedule.
MS390-48U-HW is managed by Cisco Meraki Dashboard after the device is claimed into an organization and added to a network. A local status page assists initial connectivity and IP configuration. Firmware and port policy administration use the Meraki management workflow.
Yes. MS390-48U-HW reached Cisco end-of-sale on 28 March 2025, and the announced hardware support deadline is 28 March 2032. The lifecycle milestone matters for replacement planning and continued Cisco service. ORM stock condition and purchasing terms are independent of Cisco lifecycle status.
MS390-48U-HW may be ordered from ORM Systems as new sealed or certified refurbished, with up to 3-year extended warranty on new stock and up to 1 year on refurbished stock. Cisco hardware service remains bounded by 28 March 2032. ORM offers 30-day returns subject to terms.
MS390-48U-HW has 48 RJ-45 access ports, all operating as Gigabit Ethernet downlinks. The access count excludes the management interface, fiber uplinks and dedicated physical stacking connectors. Network patching should be allocated against the access ports only. Confirm installed transceivers, entitlement status and power requirements against the exact part number before finalizing the equipment schedule.
MS390-48U-HW uses a modular uplink slot that accepts MA-MOD-2X40G or MA-MOD-8X10G. Optical transceivers are selected for the fiber media and destination port type. Stack connectors do not substitute for uplink interfaces. Confirm installed transceivers, entitlement status and power requirements against the exact part number before finalizing the equipment schedule.
Yes. MS390-48U-HW belongs to the MS390 physical stacking family and uses dedicated stacking ports with 480 Gbps stack bandwidth. Hardware stacking is distinct from grouping switches for Meraki Dashboard administration. Check hardware compatibility and the supported cable parts before joining an existing stack.
MS390-48U-HW supports static routing and OSPF in the Cisco Meraki access-switch platform. Routing policies are configured within Meraki Dashboard and depend on the appropriate licensed organization. The device should not be specified as a replacement for a full core routing platform.
MS390-48U-HW has a published maximum load of 844.9W and a 822W shared endpoint power budget. The platform requires an appropriate AC circuit and rack power arrangement. PoE demand and switch draw should not be treated as the same rating. Confirm installed transceivers, entitlement status and power requirements against the exact part number before finalizing the equipment schedule.
Yes. MS390-48U-HW has a Rack-Mount 1U chassis with a 445 mm width and 488 mm depth. Rack plans must reserve suitable ventilation, cable clearance and electrical supply. The stack and optical cables should be routed without obstructing module access. Confirm installed transceivers, entitlement status and power requirements against the exact part number before finalizing the equipment schedule.
