Lenovo 00WT036 — Mellanox SX1710 SwitchX-2 36-Port QSFP+ 40/56GbE Managed Ethernet Switch, 1U
Technical Identity
The Lenovo 00WT036 is the Lenovo part number for a Mellanox SX1710 — a 1U SwitchX-2 based Open Ethernet switch with 36 QSFP+ ports. The SX1710 platform delivers 2.88Tb/s of non-blocking throughput across 36 ports of 40GbE (56GbE supported on the platform), with each QSFP+ port splittable to 4 x 10GbE using breakout cables. Management is by MLNX-OS on an onboard x86 dual-core control plane. Lenovo-branded OEM build of Mellanox hardware. Protocol: Ethernet. Condition: Refurbished.

Engineering Context
The SX1710 behind Lenovo 00WT036 is the 36-port QSFP+ member of the SwitchX-2 Open Ethernet line. All 36 ports are line-rate 40GbE with no oversubscription, so the platform is normally deployed as a leaf or spine in a two-tier 40GbE fabric rather than as an access switch. Because each QSFP+ cage can be broken out to 4 x 10GbE, one chassis can also aggregate up to 144 x 10GbE server links where the cabling plan supports it. Mellanox encodes PSU population and airflow direction in the model suffix — MSX1710-BS2F2 and MSX1710-BS2R2 are the same switch with opposite airflow — so the airflow of a 00WT036 unit must be read from its own label, not inferred from the Lenovo part number.
Use Cases

40GbE leaf or spine in a two-tier Clos fabric for virtualisation, storage or analytics clusters.
10GbE server aggregation using 4 x 10GbE QSFP+ breakout cabling.
Low-latency Ethernet fabric for RoCE-attached storage.
Like-for-like replacement or cold spare for an installed 00WT036 / SX1710 switch.

What This Is NOT

NOT an InfiniBand switch. The 00WT036 / SX1710 is an Ethernet switch. The SwitchX-2 InfiniBand equivalents are the SX6xxx family (for example SX6036, SX6710).
NOT a 100GbE, 200GbE or 400GbE switch. Maximum per-port rate is 40GbE (56GbE on the platform). 100GbE needs Spectrum, 200/400GbE needs Spectrum-2 or later.
NOT a QSFP28, QSFP56 or OSFP switch. The cages are QSFP+; QSFP28, QSFP56 and OSFP optics and cables are not supported here.
NOT the same part number as MSX1710-BS2R2 or MSX1710-BS2F2. Those are Mellanox catalogue configurations of the same SX1710 platform; 00WT036 is the Lenovo OEM number and its PSU/airflow configuration must be confirmed per unit.
NOT a Cumulus Linux or SONiC unit as shipped. The platform is Open Ethernet capable, but the operating system actually installed must be verified — do not assume a third-party NOS is present or licensed.
NOT supplied with QSFP+ transceivers, DAC/AOC or breakout cables, rail kits or spare power supplies.

Compatibility & Hard Constraints

Typical endpoints: Mellanox ConnectX-3 / ConnectX-3 Pro 40GbE QSFP+ adapters and other 40GbE QSFP+ server NICs; 10GbE SFP+ NICs via 4 x 10GbE breakout.
Typical cabling: QSFP+ 40GbE passive copper DAC, active optical cable, and QSFP+ to 4 x SFP+ breakout assemblies. Verify module recognition in the switch CLI.
Software: MLNX-OS on the switch. Migration to a third-party network operating system requires separate licensing and platform qualification.
Rack and power: 1U plus rails. PSU count, PSU wattage and airflow direction must be confirmed from the unit label and matched to the rack cooling plan.
Pre-deployment verification: firmware / MLNX-OS level, licence state, port breakout profile, PSU population, airflow direction.

Frequently Asked Questions (FAQ)
Q. What exactly is the Lenovo 00WT036?
00WT036 is the Lenovo part number for a Mellanox SX1710: a 1U SwitchX-2 managed Open Ethernet switch with 36 QSFP+ ports at 40GbE, 2.88Tb/s non-blocking throughput and 220ns port-to-port latency at 40GbE.
Q. Is the 00WT036 the same switch as an MSX1710-BS2R2?
Same SX1710 platform, different part numbering. MSX1710-BS2R2 and MSX1710-BS2F2 are Mellanox catalogue configurations that differ in airflow direction; 00WT036 is the Lenovo OEM number, and its PSU and airflow configuration must be read from the unit label.
Q. Does the 00WT036 run InfiniBand?
No. The 00WT036 / SX1710 is an Ethernet switch. SwitchX-2 InfiniBand switches are separate models in the SX6xxx line.
Q. Can each 40GbE port on the 00WT036 be split to 10GbE?
Yes. Each of the 36 QSFP+ ports on the SX1710 can be broken out to 4 x 10GbE with a breakout cable, giving up to 144 x 10GbE, subject to the port breakout profile configured in MLNX-OS.
Q. What connector does the 00WT036 use?
QSFP+ only, 36 cages. QSFP28 (100GbE), QSFP56 (200GbE) and OSFP modules are physically or electrically incompatible with this platform.
Q. What must be verified before ordering the 00WT036?
PSU population, airflow direction, MLNX-OS firmware level and licence state. T.E.S can confirm these from the unit label on request before dispatch.
