IBM 94Y5219 — Flex System EN4023 10Gb Scalable Switch Module (Licence State Unconfirmed)
Identity
This listing is for an OEM service part carrying the printed part number 94Y5219, an IBM / Lenovo Flex System component. It is listed across the reseller market as the replacement or service number paired with 94Y5218 for the Flex System EN4023 10Gb Scalable Switch. The hardware detail below is taken from Lenovo Press product guide TIPS1070 for the EN4023. Note the caveat: Lenovo Press documents the EN4023 under base part number 94Y5212 and does not list 94Y5218 or 94Y5219 in its part-number table, so the mapping rests on reseller data. T.E.S confirms the exact model from the unit label before dispatch.
Read the licensing note below before you order. On a scalable switch, the part number tells you nothing about how many of its ports are actually usable.
What is confirmed about 94Y5219
The printed part number is 94Y5219, listed across the market as the replacement number paired with 94Y5218 for the Flex System EN4023 10Gb Scalable Switch.
Per Lenovo Press TIPS1070, the EN4023 hardware comprises 42 internal full-duplex 10 Gigabit ports and two internal 1 GbE ports connected to the chassis management module.
Per the same guide, externally it has fourteen SFP/SFP+ ports for 1/10 Gb connections and two external QSFP+ ports, each supporting a single 40 Gb uplink.
Per the same guide, the base switch (part number 94Y5212) is initially licensed for 24 ports, internal or external.
Per the same guide, Feature-on-Demand Upgrade 1 (94Y5158) enables 16 additional 10 GbE ports plus the two 40 Gbps QSFP+ uplinks; Upgrade 2 (94Y5159) enables 16 more 10 GbE ports; Upgrade 3 (47C9993) enables FCoE on internal ports and Flex Ports on the external ports for 10 Gb FCoE or 8/16 Gb Fibre Channel.
Per the same guide, a fully upgraded EN4023 reaches 56 10 GbE ports plus two external 40 GbE QSFP+ ports. The switch and all its FoD upgrades are withdrawn from marketing.
What is not yet confirmed
This list is deliberate. It is what T.E.S could not establish from documentation, and it is read off the physical unit before dispatch rather than guessed at here.
Which Feature-on-Demand licences are activated on this specific unit. This is the headline unknown and it materially changes what you are buying: a base-licensed EN4023 gives you 24 usable ports with the two 40 Gb uplinks disabled, while a fully upgraded one gives you 56 ports plus both 40 Gb uplinks. FoD licences are keyed to the individual switch and generally do not transfer on resale. T.E.S cannot determine the licence state from the part number and does not assume upgrades are present — price this unit as a base switch unless we confirm otherwise in writing.

Firmware level, and any residual configuration left by the previous owner.
Which Flex System chassis it was pulled from, and the running hours behind it.
SFP+ transceivers, QSFP+ transceivers and DAC cables are not included and are not implied.
Request label photos before you order
Ask us for photographs of this unit's product label and we will send them before you commit to anything. This is a single unit, and the licence state is the whole commercial question. Where we have a matching chassis available we will boot the switch, read out the activated port licences and tell you exactly what is enabled before you order — and we will re-quote on that basis rather than charging you for capacity you do not get. If the label does not match what is described on this page, we say so and re-quote or cancel — we do not ship a substitute and hope it fits. Quote part number 94Y5219 when you contact us.
Frequently asked questions
What exactly am I buying with 94Y5219?
A refurbished IBM / Lenovo Flex System I/O module whose printed number is 94Y5219, listed across the market as the replacement number paired with 94Y5218 for the Flex System EN4023 10Gb Scalable Switch. Lenovo Press TIPS1070 documents the EN4023 hardware as 42 internal 10 Gb ports, fourteen external SFP/SFP+ ports and two external 40 Gb QSFP+ ports. What is not established is how many of those ports are licensed on this unit.
How many ports on 94Y5219 are actually usable?
Not confirmed, and this is the most important question on this listing. Per Lenovo Press TIPS1070 the EN4023 base switch is licensed for 24 ports; Feature-on-Demand Upgrade 1 adds 16 ports plus the two 40 Gb QSFP+ uplinks, Upgrade 2 adds 16 more, and a fully upgraded switch reaches 56 10 GbE ports plus two 40 GbE uplinks. Those licences are keyed to the individual switch and generally do not transfer on resale. T.E.S cannot read the licence state from the part number — assume base licensing unless we confirm otherwise in writing.
Will T.E.S confirm the licence state before shipping 94Y5219?
We will try, and we will tell you either way. Where we have a matching Flex System chassis available we boot the switch, read out the activated port licences and report exactly what is enabled before you order. Where we cannot, we say so plainly rather than implying the upgrades are present. The price on this listing is set on the assumption of a base-licensed switch.
What if 94Y5219 turns out not to be what I need?
Tell us the port count and uplink capability you are designing around before you order and we check the unit against it first. If the switch is base-licensed and you need the 40 Gb uplinks, we will say so — those uplinks are disabled by default and require a Feature-on-Demand licence that is withdrawn from marketing. If it ships and we misrepresented the licence state, it comes back at our cost.
Is the 94Y5219 module tested?
It is cleaned, visually inspected and bench-tested where a suitable test topology is available. For a Flex System I/O module that requires a matching chassis on the bench, which is not always available. Ask what was actually done to this unit and we will tell you rather than implying more than was done.
Can I still buy the Feature-on-Demand upgrades for 94Y5219?
Per Lenovo Press TIPS1070, the EN4023 switch and all of its FoD upgrades are withdrawn from marketing. That means the upgrade licences are not straightforwardly purchasable new from Lenovo, which is exactly why the licence state of a second-hand unit matters. Factor that into your decision before ordering, and ask us what this unit shows.

On OEM service parts whose exact model is not established by the part number alone, we publish what we can verify and name what we cannot, instead of filling the gap with plausible-sounding specifications. Every unit is photographed and its label read before dispatch. If the unit differs from this page, we tell you before we ship.
