Extreme Networks 08G20G4-24P Summit X250e 24-Port GbE PoE Managed Switch | Wty

Key Benefits

• 24 x Gigabit PoE ports, 185W budget: Power standard PoE devices including IP phones, wireless access points, and IP cameras across a full access layer without additional injectors.
• 4 x SFP mini-GBIC uplinks: Flexible fibre or copper uplink options for connecting to aggregation or core switches — supports standard 1GbE SFP modules.
• ExtremeXOS operating system: Feature-rich CLI and web management with VLAN support, QoS, STP, RSTP, MSTP, and access control — the same OS used across Extreme Networks enterprise switches.
• Layer 2/3 management: 802.1Q VLANs, static routing, and inter-VLAN forwarding allow flexible network segmentation without a dedicated router.
• Enterprise-grade security: 802.1X port-based authentication, MAC address filtering, and DHCP snooping protect the network edge.
• Certified refurbished with 12-month warranty: Professionally tested and graded by Reboot IT — Melbourne's enterprise networking specialists since 2001.

Performance in Use

The Extreme Networks Summit X250e-24p is a proven enterprise access switch built on the ExtremeXOS platform. With 24 Gigabit PoE ports and 185W of shared power, it suits deployments of standard 802.3af PoE devices — IP desk phones (4–6W), lightweight wireless APs (up to 15.4W per port), and standard IP cameras. The four SFP uplink slots provide fibre or Gigabit copper connectivity to upstream switches, with flexibility to mix module types as your infrastructure requires.

ExtremeXOS is a robust network operating system that supports advanced features beyond basic switching. VLAN segmentation, QoS traffic prioritisation for voice and video, and rapid spanning tree convergence are all included. The switch's 802.1X implementation integrates with RADIUS servers for centralised port authentication — standard practice in enterprise environments where guest and device access must be controlled at the network edge.

As legacy enterprise hardware at an accessible price point, the Summit X250e-24p is well-suited for budget-conscious deployments, lab environments, secondary sites, and organisations standardised on Extreme Networks infrastructure. Note that this switch supports standard 802.3af PoE (up to 15.4W per port), not PoE+ (802.3at). Devices requiring more than 15.4W — such as high-power APs or PTZ cameras — should be evaluated against this limit before deployment.

Frequently Asked Questions

Does this switch support PoE+ (802.3at)?

No — the Summit X250e-24p supports standard 802.3af PoE only, with a maximum of 15.4W per port. Devices requiring PoE+ (up to 30W) such as high-power access points or PTZ cameras are not supported. IP phones, standard APs, and basic IP cameras typically fall within the 15.4W limit.

What SFP modules are compatible with the uplink ports?

The four uplink slots accept standard 1GbE SFP mini-GBIC modules — both fibre (SX, LX, ZX) and copper (1000BASE-T) modules are supported. Extreme Networks-branded modules are recommended for full compatibility.

Can the switch route between VLANs?

Yes — the Summit X250e-24p supports inter-VLAN static routing via ExtremeXOS, allowing traffic to route between VLANs on the switch without a separate router. Dynamic routing protocols are not included in the base configuration.

What network operating system does it run?

The switch runs ExtremeXOS, Extreme Networks' enterprise operating system. It provides CLI, web, and SNMP management with a consistent command structure across the Extreme Networks product range.

Is this suitable as a primary access switch?

It works well for smaller deployments, secondary sites, lab environments, or organisations with standard 802.3af PoE requirements. For primary enterprise infrastructure requiring PoE+ or 10G uplinks, consider a more current switch model.
