FastIron was the Foundry Networks name for its access and wiring closet switches, the boxes that connected desks, phones and access points and uplinked to a BigIron core. The family ran for the whole life of the company and was refreshed more often than any other line, which is why so many differently shaped switches share the name. The switching hub covers the underlying features.
FastIron is unusual among Foundry names because it outlived the company. Brocade kept it as the software brand for its campus switches, and Ruckus, now a CommScope brand, still ships FastIron releases for the ICX line. A FastIron manual dated today describes a living product, not an archive.
02 /Generations
| Model | Approximate years | Type | Notes |
|---|---|---|---|
| FastIron Workgroup | 1997 to 2000 | Fixed Fast Ethernet | First Foundry access switch, Gigabit uplinks |
| FastIron II / II Plus | 1999 to 2002 | Small chassis | Layer 2/3 for larger closets |
| FastIron 400 / 800 / 1500 | 2001 to 2004 | Chassis, JetCore | Shared hardware with BigIron; closet aggregation |
| FastIron Edge (FES) | 2002 to 2006 | Fixed, PoE options | Built for IP telephony rollouts |
| FastIron Edge X 424 / 448 | 2004 to 2007 | Fixed Gigabit, 10 Gigabit uplinks | Most common second-hand model |
| FastIron SuperX | 2005 to 2008 | Chassis, PoE | Modular closet and small core |
| FastIron GS / LS | 2006 to 2008 | Stackable | GS with PoE, LS as the lower cost line |
03 /Features that defined the line
Each generation added the access features of its period. VLANs and trunking were present from the start. Power over Ethernet arrived with the Edge series for IP phones. 802.1X port authentication, MAC filtering and DHCP snooping came in the early 2000s software trains. Rapid and multiple spanning tree replaced classic STP. On models with a router image, OSPF, RIP and VRRP turned a closet switch into a small Layer 3 core.
FoundryNet is an independent reference and archive, not affiliated with Foundry Networks, Brocade, Broadcom, Ruckus or CommScope. Model lists are best effort; check the label and show version on any unit before trusting a spec.
04 /Switch code versus router code
Foundry shipped two IronWare images for many FastIron models. The switch image did Layer 2 only, with a single management IP. The router image added IP routing between VLANs through virtual interfaces and the routing protocols. The two images used different configuration syntax for VLAN IP addressing, so a config from one will not load cleanly on the other. Second-hand units arrive with either, and the file name in show flash tells you which.

05 /Why it sold in schools and enterprises
FastIron switches undercut the dominant campus vendor on price per port while offering a CLI that felt familiar, plus PoE and Gigabit to the desk earlier than many competitors. School districts, universities and mid-sized enterprises bought them in volume, often alongside a BigIron core, which is why FastIron datasheets and the FES feature guide were among the most requested pages on this domain.
06 /Running one today
The Edge X and GS models are the practical choices. Non-PoE versions are quiet enough for a home office; PoE versions run hotter and louder. Images and release notes for the Foundry-era models sit behind a support login at the current owner, so a unit without a working image is hard to revive. Brocade-era FCX and ICX units are a better buy for a lab because their software still receives updates and the CLI is the same lineage.
07 /Questions
Is FastIron still made?
The hardware in this article is not, but the FastIron software name continues on Ruckus ICX switches, a CommScope brand. Current FastIron releases share CLI conventions with the Foundry-era switches, so knowledge of one transfers to the other.
What is the difference between FastIron Edge and Edge X?
FastIron Edge (FES) was a Fast Ethernet access switch with PoE options for IP telephony, from around 2002. FastIron Edge X (FESX) moved to Gigabit on every port with optional 10 Gigabit uplinks, from around 2004, and is the model most often found second-hand.
Can a FastIron switch route between VLANs?
Only when running the router image. The switch image is Layer 2 with a single management address. The router image adds virtual interfaces per VLAN, static routes, RIP, OSPF and VRRP on supported models.
Where do I get FastIron firmware for an old Foundry switch?
The current owner of the line hosts images behind a support account, and Foundry-era builds are not always listed. Check the flash on the unit first; many second-hand switches still carry a usable image and the matching boot code.
Are FastIron switches quiet enough for a homelab?
Non-PoE Edge X and LS units are office quiet. PoE models and the SuperX chassis are not. Fan noise is the main complaint in forum threads, followed by the lack of current firmware for Foundry-era units.
Which Foundry switch is closest to a modern Ruckus ICX?
The FastIron GS and LS stackables. They introduced the stacking model and the software train that Brocade carried into FCX and then ICX, and their configuration files look much like a current ICX config.
