X440-G2-12p-10GE4

Calculate powered-device demand against the shared 200 W allocation

All twelve 10/100/1000BASE-T front-panel data ports on X440-G2-12p-10GE4 support PoE+. The manufacturer power table assigns the model a total 200 W PoE allocation from its internal supply. This is a shared switch budget rather than 200 W on each socket, and twelve PoE+ labels do not establish that every endpoint can draw its individual maximum at once. Build a powered-device list and reconcile the combined demand before selecting the switch. All twelve copper ports support half-duplex and full-duplex communication, which distinguishes this exact port configuration from variants with split duplex groups.

Reserve optical positions for either Ethernet uplinks or stacking

The hardware guide identifies four unpopulated optical positions that can operate as 1Gb links or, with additional licensing, as 10Gb data links. It separately allows two positions to be converted for stacking, leaving two Ethernet positions alongside the two stack links. A plan requiring two 10Gb data uplinks plus stacking therefore still needs the applicable license for the non-stacking data ports. Specify the intended allocation and supported optical modules in the quotation. The 10GE4 suffix and the printed SFP+ marking establish a hardware variant; neither confirms that the supplied unit already holds the requested license.

Treat the external supply as redundancy rather than added PoE capacity

The rear-panel documentation shows an AC input, grounding lug and redundant power connector. The technical table lists 200 W for the internal PoE budget and 200 W for external RPS operation on this model, explicitly describing the latter as redundant power only. It does not grant the additive power behavior described for a different 48-port family member. Confirm a compatible RPS and connecting cable as separate supplied items when resilience is required. The fixed internal supply reference specifies 100–240 VAC and 50–60 Hz; the quotation still needs the correct regional cord and any external power accessories.

Check the actual management workflow and environmental requirement

Administration uses a dedicated 10/100/1000BASE-T management connection and an RJ45 serial console, separate from the twelve powered data interfaces. The front USB 2.0 port is operational with ExtremeXOS 22.2 or later. Record the installed release and backup process instead of treating this threshold as software entitlement. The unpackaged chassis measures 4.4 cm high, 30.51 cm wide and 26.11 cm deep; the published weight is 3.04 kg. Numeric operating-temperature limits are omitted because the official family grouping and technical-specification footnote conflict for 12p. Obtain manufacturer clarification for the proposed environment rather than applying another extended-temperature model’s rating.
