Description
Extreme Networks X440-G2-24X-10GE4 | Summit 24-Port SFP Switch In-Stock
Dynamic Product Introduction
Loss of optical fiber aggregation or edge switch routing in an industrial network backbone halts data exchange between field PLC networks, SCADA servers, and remote I/O nodes. The Extreme Networks X440-G2-24X-10GE4 (P/N: 16535) serves as a high-density, low-latency Gigabit fiber edge switch designed for demanding automation and enterprise topologies. Powered by ExtremeXOS (EXOS), it manages complex VLAN routing, Ethernet Automatic Protection Switching (EAPS), and role-based policy enforcement while providing 24 SFP optical ports and 4 dedicated 10GbE SFP+ uplinks for high-bandwidth backhaul.
When an operational switch encounters optical transceiver port failure, power supply board degradation, or backplane packet drops during high-volume data traffic, sourcing an exact drop-in Extreme X440-G2-24X-10GE4 replacement restores network integrity. Installing a fully bench-tested replacement unit allows network engineers to rack-mount the hardware directly into existing 19-inch enclosures, quickly restoring established network topologies without modifying field fiber runs or altering cabinet panel layouts. Swapping in a fresh switch restores immediate sub-50ms ring recovery, full wire-speed packet forwarding, and secure network access across your automation infrastructure.

Global Sourcing & Live-Test SOP (Transparency Core)
Procuring secondary-market managed networking hardware like the Extreme Networks X440-G2-24X-10GE4 requires strict bench diagnostic screening to verify optic port link integrity, switching fabric health, and ExtremeXOS flash memory retention. Every incoming switch passes through an intensive five-stage quality assurance protocol:
- Inbound Verification: Part numbers (16535), serial tags, MAC address plates, and chassis physical conditions are verified against original manufacturing databases. Technicians conduct visual inspections under magnification to check SFP slot cages, fan assemblies, and power receptacle connectors.
- Live Simulation: The X440-G2-24X-10GE4 is installed in an active network diagnostic rack and powered using a regulated AC line supply.
- Diagnostics: Technicians load factory default EXOS software images via the console port. Optical link tests are conducted across all 24 SFP ports and 4 SFP+ 10GbE uplinks using calibrated SFP/SFP+ transceivers and loopback fiber jumpers. Full line-rate traffic generation tests measure packet loss, latency, and VLAN tag processing. The unit then undergoes a 24-hour burn-in period inside a thermal chamber under continuous traffic load to rule out ASIC thermal lockups.
- Final Prep: Flash memory is cleared back to clean factory default configurations, console settings are reset, connector dust caps are installed over all SFP ports, and the switch is sealed inside static-shielding ESD packaging before freight transit.
The Field Engineer’s Pitfall Guide
- ❗ SFP+ Uplink Port Speed Configuration in EXOS: —though you might expect the 4 uplink ports to auto-negotiate, connecting a 1GbE SFP transceiver into an SFP+ slot without explicitly configuring the port speed to 1G in EXOS will result in a link-down state.
- ❗ Unsynchronized ExtremeXOS Firmware Revisions in SummitStack-V: When adding a replacement X440-G2-24X-10GE4 to an existing stack, attempting to form a stack without matching the EXOS firmware version to the active stack master will cause stacking synchronization failures and keep the node in a disabled state.
- ❗ Inserting Incompatible Non-DOM Optical Transceivers: Using unapproved third-party SFP modules without Digital Optical Monitoring (DOM) support can cause optical power diagnostic errors in EXOS, making it difficult to monitor fiber link degradation or light loss in the field.
Intent-Driven FAQ
Will swapping out an X440-G2-24X-10GE4 require uploading an EXOS configuration file?
Yes. Replacement switches arrive cleared to factory baseline settings. You must upload your saved EXOS configuration file (.cfg) via TFTP/SFTP or console interface, or allow the network’s DHCP auto-provisioning server to pushes parameters upon initial boot.
What optical transceivers are supported on the 24 SFP ports of the X440-G2-24X-10GE4?
The 24 SFP ports support standard 100BASE-FX and 1000BASE-X SFP transceivers, including SX, LX, EX, ZX, and BiDi optical modules, as well as 1000BASE-T copper SFP modules.
Can the 4 uplink ports be used for stacking and network links simultaneously?
Yes. When using SummitStack-V technology, user-designated 10GbE uplink ports can be assigned to stacking interfaces, while any remaining SFP+ ports function as standard high-speed 10GbE uplink or downlink channels.
What indicates a fan assembly or thermal warning on the X440-G2 faceplate?
A yellow or amber status LED on the front faceplate (labeled “SYS” or “FAN”) indicates an internal cooling fan fault or an internal temperature threshold breach detected by EXOS system diagnostics.
What warranty coverage comes with pre-inspected replacement switches?
All verified Extreme Networks X440-G2-24X-10GE4 switches come backed by a comprehensive 1-year replacement warranty. If the unit experiences switching fabric failure, optical port signal loss, or power supply breakdown under standard operating conditions within 12 months, it is swapped directly from available warehouse inventory stock.
