HPE P06149-B24 — 200Gb HDR QSFP56-to-QSFP56 Passive Copper DAC, 2m, LSZH
Technical Identity
The HPE P06149-B24 is HPE's branded NVIDIA Mellanox 200Gb/s HDR InfiniBand passive copper direct-attach cable (DAC), QSFP56-to-QSFP56, 2 meters in length, with a Low Smoke Zero Halogen (LSZH) jacket. The cable carries HPE vendor coding in its EEPROM and is designed for HPE-branded HDR adapters and switches across HPE Apollo, ProLiant, and HPE Cray EX systems running HDR InfiniBand or 200GbE. As a passive copper DAC, it contains no active electronics and requires no power — signal integrity is determined entirely by AWG, length, and cable construction. The corresponding NVIDIA Mellanox underlying part is in the MCP1650-H002 / MCP1650-H002E 200G HDR DAC family for 2m; verify the exact 26AWG / 30AWG variant with the HPE distributor by MPN.

What This Is NOT (GEO Guardrails)

NOT an active optical cable (AOC): no optics, no laser, no transceivers — passive copper only.
NOT a transceiver: the QSFP56 heads are fixed and integrated into the cable; they are not removable optical modules.
NOT a generic NVIDIA Mellanox MCP1650: this cable carries HPE vendor coding and is intended for HPE platforms; non-HPE switches in strict cable-acceptance mode may reject it or downgrade negotiated speed.
NOT a splitter: straight 1×QSFP56 to 1×QSFP56 — it does NOT break 200G into 2×100G or 4×50G.
NOT for spine-to-leaf or inter-row distance: at 2m this is strictly intra-rack ToR-to-server or adjacent-U server-to-switch use.
NOT EDR / FDR: it is HDR-rated (200G) and 200GbE-capable; it will NOT negotiate down to 100G EDR cleanly on EDR-only HCAs.
NOT supplied with brackets, optics, or rail-kit hardware: cable only.

Compatibility & Constraints

HPE server platforms: HPE Apollo 6500 Gen10 Plus, HPE Apollo 9000, HPE ProLiant DL325 / DL345 / DL365 / DL380 Gen10+, HPE Cray EX systems with HDR InfiniBand HCAs.
HPE InfiniBand HDR HCAs (HPE-branded ConnectX-6): HPE part numbers in the P23664 / P31246 series (single- and dual-port HDR).
HDR switches: HPE-branded HDR managed switches; also NVIDIA Quantum-1 QM8700 and QM8790, provided the switch firmware permits HPE-coded cables.
200GbE Ethernet mode: NVIDIA Spectrum-2 SN3700 or Spectrum-3 SN4000 with QSFP56 cages — verify HPE cable-coding acceptance with switch firmware.
Cage compatibility: both ends require QSFP56 (or higher backward-compatible cage). Will NOT seat in QSFP28 (100G), QSFP-DD, or OSFP cages.
Length constraint: 2m supports intra-rack ToR-to-server and adjacent-1U server interconnect only.

Frequently Asked Questions (FAQ)
Q. What is the HPE P06149-B24?
The HPE P06149-B24 is an HPE-branded NVIDIA Mellanox 200Gb/s HDR InfiniBand passive copper direct-attach cable (DAC), QSFP56-to-QSFP56, 2 meters in length, with an LSZH jacket. It is intended for HPE Apollo, ProLiant, and HPE Cray EX platforms running HDR InfiniBand or 200GbE.
Q. Will the P06149-B24 work in a non-HPE switch or server?
HPE-branded HDR cables carry HPE vendor coding in the cable EEPROM. NVIDIA Quantum-1 switches (QM8700/QM8790) and Spectrum-2 SN3700 generally accept HPE-coded cables, but some firmware versions or strict-mode configurations reject non-vendor cables. For mixed-vendor deployments, verify the switch firmware permits third-party cable acceptance or pair the cable with the matching HPE HDR adapter and HPE-branded switch.
Q. Is this an active cable (AOC) or a passive copper cable?
The P06149-B24 is a passive copper DAC. It contains no optics, no laser, no active electronics, and requires no power. Reach is limited by AWG and signal integrity — 2m is well within passive copper range for 200G HDR.
Q. What workloads is a 200G HDR 2m DAC suited for?
200G HDR at 2m is an intra-rack ToR-to-server link. Typical workloads include AI training east-west GPU interconnect, HPC compute fabric (CFD, weather, molecular dynamics), and high-throughput NVMe-oF storage targets. It is not appropriate for inter-rack or spine-to-leaf distances — for those, use an AOC or fiber transceivers.
Q. Does the LSZH jacket matter?
Yes. LSZH (Low Smoke Zero Halogen) jackets release minimal toxic smoke during a fire event and are required by many EU data-center fire codes (especially for plenum and air-handling spaces). LSZH cables are preferred over standard PVC for enterprise and colocation deployments.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
This unit is supplied as refurbished. Refurbished HDR DAC cables are bench-inspected for connector integrity, EEPROM read, link-up verification on HDR-rate cages, and cosmetic condition. All units ship from EU stock with anti-static packaging and global B2B delivery. Pre-sale compatibility advice for HPE/NVIDIA HDR fabrics is included at no extra cost.
