X440-G2-12t8fx-GE4 Overview
Preserve the fixed 100BASE-FX connections during replacement
The eight LC fiber connections on X440-G2-12t8fx-GE4 are fixed 100BASE-FX interfaces. They are distinct from its four unpopulated 1GBASE-X SFP positions and from the twelve 10/100/1000BASE-T copper ports. This mix can matter when replacing equipment attached to an existing Fast Ethernet fiber installation. Record each link’s speed and connector before selecting the replacement; an LC connector does not, by itself, identify a Gigabit or 10GbE connection. Verify the installed fiber and remote endpoint against the exact manufacturer interface requirements rather than selecting a transceiver from connector shape alone.
Keep this extended-temperature variant outside a stack plan
Extreme’s X440-G2 installation guide explicitly excludes X440-G2-12t8fx-GE4 from SummitStack-V support. The same family documentation excludes the extended-temperature variants from the licensed 10GbE Ethernet uplift described for other X440-G2 models. Its four SFP positions are therefore documented here as Gigabit uplinks, without a promised software upgrade to 10GbE. The manufacturer front-panel drawing includes a stack-number indicator, but that marking must not override the stated model restriction. Specify this exact GE4 order when preserving these boundaries; the 12t-10GE4 and 12p-10GE4 are different configurations.
Separate AC operation from an external redundancy package
The exact rear-panel diagram identifies an AC power input socket, a grounding lug and one redundant power input. The family guide explains that redundant operation requires a compatible external supply. A connector is not an included second power source, so reconcile the supply and connecting cable as separate quotation items if redundancy is required. The hardware guide lists the unpackaged chassis at 4.4 cm high, 30.51 cm wide and 26.11 cm deep, weighing 2.95 kg. Use those chassis dimensions for space planning and check the actual mounting accessories being supplied; these figures do not describe a shipping carton.
Match local management procedures to the installed software
A dedicated 10/100/1000BASE-T Ethernet management port and an RJ45 serial console support administration independently of the data interfaces. The front USB 2.0 port is documented as operational with ExtremeXOS 22.2 or later. That version threshold concerns this USB function; it does not identify the software installed on a particular switch or establish entitlement to a release. Before migration, record the actual image, configuration backup method and management cabling. The published operating range for this model is 0–60°C, which must be assessed alongside the site’s installation requirements rather than extended into an unsupported environmental certification.
