Lenovo 00MP528 1.25M MELLANOX EDR IB Passive Copper QSFP28 Cable

Lenovo 00MP528 1.25M EDR InfiniBand Passive Copper QSFP28 Cable

Overview

The Lenovo 00MP528 is a 1.25-meter passive copper Direct Attach Cable (DAC) with QSFP28 connectors, designed for Enhanced Data Rate (EDR) InfiniBand interconnects running at 100Gb/s. At this length, passive copper eliminates the need for active optical components — no transceivers, no separate power budget for optics — making it the practical choice for intra-rack and short cross-rack server-to-switch runs where latency and cost both matter. If your HPC cluster, AI/ML fabric, or high-density compute rack needs low-overhead 100G connectivity between adjacent nodes and switches, the 00MP528 fits that gap without the overhead of an active cable assembly.

Compatibility

The 00MP528 is designed for Lenovo ThinkSystem servers and Mellanox (NVIDIA) EDR InfiniBand switch ports equipped with QSFP28 interfaces. Compatible host bus adapters and switch line cards include Mellanox ConnectX-4 and ConnectX-5 series HCAs, and EDR-capable Mellanox SB7700/SB7800 series InfiniBand switches. Verify your HBA and switch firmware support passive DAC operation at 100Gb/s before deploying — some configurations require explicit DAC mode enablement in the port settings. Sourced for Lenovo ThinkSystem platform deployments; confirm QSFP28 EDR port availability on your specific switch and adapter models.

Installation Notes

Passive copper DACs at 1.25m are insertion-ready — seat the QSFP28 connector firmly until the latch clicks on both ends. No optical alignment, no power sequencing, and no transceiver configuration required. Cable weight is 1.00 lb; route with bend-radius management in mind for dense patch panels. Country of origin is MX (Mexico). UNSPSC code 26121609 applies for procurement classification.
