Lenovo 00MP533 — Mellanox EDR InfiniBand QSFP28 Passive Copper Cable (Length Unconfirmed)
Identity
This listing is for a Lenovo service part carrying the printed part number 00MP533. It belongs to Lenovo's 00MP5xx family of Mellanox EDR InfiniBand passive copper QSFP28 cables. The one attribute that matters most for a DAC cable — its length — is not confirmed for this part number, and this page does not pretend otherwise.
The reasoning, stated openly so you can weigh it yourself: Lenovo's published option numbers in this family step in increments of four — 00MP516 (0.5 m), 00MP520 (0.75 m), 00MP524 (1 m), 00MP528 (1.25 m), 00MP532 (1.5 m, feature code ASQX), 00MP536 (2 m), 00MP560 (3 m). 00MP533 sits immediately above 00MP532, which makes 1.5 m the most likely length on the pattern that Lenovo issues a service number adjacent to each option number. T.E.S has not been able to corroborate that mapping against a Lenovo parts document, so it is presented as inference, not fact. T.E.S measures the cable, photographs its printed length marking and confirms it before dispatch.
What is confirmed about 00MP533
The printed part number is 00MP533, a Lenovo part in the 00MP5xx Mellanox EDR InfiniBand cable family.
The family is passive copper direct-attach (DAC) with QSFP28 connectors on both ends, rated for EDR InfiniBand at 100 Gb/s.
Passive means no electronics in the signal path — no retimer, no amplifier. Reach is therefore short and depends on the host and switch SerDes.
The immediate sibling 00MP532 is documented by Lenovo and its distributors as the 1.5 m Mellanox EDR IB Passive Copper QSFP28 Cable, feature code ASQX.
Documented lengths elsewhere in the same family: 00MP516 (0.5 m), 00MP520 (0.75 m), 00MP524 (1 m), 00MP528 (1.25 m), 00MP536 (2 m), 00MP560 (3 m).
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.
The length of this cable. This is the headline unknown. The 1.5 m inference above is reasoning from Lenovo's numbering pattern, not a verified mapping — T.E.S measures the physical cable and reads its printed length marking before dispatch, and will tell you the measured length before you commit.
Wire gauge. EDR QSFP28 passive DACs ship at different AWG depending on length (30 AWG is typical for short runs, 26 AWG for longer), and gauge is not derivable from the part number.
Whether this specific unit is the Lenovo-boxed service part or an OEM Mellanox cable relabelled — the printed markings settle it.
Whether it carries a Lenovo-specific EEPROM image, which some OEM switches check on link-up.
Connector generation compatibility beyond QSFP28. QSFP, QSFP+, QSFP28, QSFP56 and QSFP-DD are distinct connector and signalling generations. This is a QSFP28 EDR-class cable and is not an HDR, NDR, OSFP or SFP-family part.
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 cable, and length is the whole question. Ask us and we will measure it end to end, photograph the printed length and part-number markings on the boot, and send both before you order. 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 00MP533 when you contact us.
Frequently asked questions
What exactly am I buying with 00MP533?
A refurbished Lenovo service part whose printed number is 00MP533, from Lenovo's family of Mellanox EDR InfiniBand passive copper QSFP28 cables — QSFP28 on both ends, passive copper, 100 Gb/s EDR class. What is not established is the length. T.E.S measures and photographs the cable before dispatch.
How long is the 00MP533 cable?
Not confirmed, and we will not guess on the page. Lenovo's option numbers in this family step by four (00MP516 = 0.5 m, 00MP520 = 0.75 m, 00MP524 = 1 m, 00MP528 = 1.25 m, 00MP532 = 1.5 m, 00MP536 = 2 m, 00MP560 = 3 m), and 00MP533 sits immediately above the 1.5 m option number 00MP532 — which makes 1.5 m the most likely answer. T.E.S has not verified that mapping against a Lenovo parts document. Ask us and we will measure the actual cable and tell you before you order.
Will T.E.S confirm the exact cable before shipping 00MP533?
Yes, as a standard dispatch step. We measure the cable end to end, read the printed length and part-number markings on the boot, and confirm the connector type. If the measured length is not what you need, we say so and cancel or re-quote before shipping.
What if 00MP533 turns out to be the wrong length for my run?
Tell us the length you need before you order and we measure this cable against it first. If it does not fit your run we will say so rather than shipping it, and we will quote the correct length from stock instead. If a cable ships and the length was misread on our side, it comes back at our cost.
Is the 00MP533 cable tested?
It is cleaned, visually inspected — connector pins, boot strain relief, jacket condition — and link-tested where a suitable EDR test topology is available. For a passive DAC that is a continuity and link-up check, not a certified signal-integrity sweep. Ask what was done to this specific cable and we will tell you.
Will 00MP533 work in a QSFP+, QSFP56 or QSFP-DD port?
It is a QSFP28 cable. QSFP, QSFP+, QSFP28, QSFP56 and QSFP-DD are distinct connector and signalling generations and are not freely interchangeable — a QSFP28 EDR cable is not an HDR, NDR, OSFP or SFP-family part. Check your port type before ordering, and ask us for connector photographs if there is any doubt.
Why T.E.S IT-SOLUTIONS
T.E.S IT-SOLUTIONS supplies refurbished enterprise networking and server hardware from EU stock to a B2B market. 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.
