Lenovo 00MP524 1M MELLANOX EDR IB Passive Copper QSFP28 Cable

Lenovo 00MP524 1M Mellanox EDR InfiniBand Passive Copper QSFP28 Cable

Overview

The Lenovo 00MP524 is a 1-meter passive copper QSFP28 cable designed for EDR (Enhanced Data Rate) InfiniBand fabric connections in high-performance computing and data center environments. Passive copper construction means no active signal conditioning components inside the cable assembly — the result is lower latency and lower power draw compared to active optical alternatives at this distance. At 1 meter, this cable is the right pick for same-rack or adjacent-rack top-of-rack switch-to-server connections where the short run eliminates any need for optical transceivers. The QSFP28 form factor supports 100Gb/s aggregate throughput across four lanes, making it suitable for EDR InfiniBand host channel adapter (HCA) to switch port interconnects where bandwidth density matters.

Compatibility

Designed for use with Mellanox EDR InfiniBand switches and host channel adapters using QSFP28 ports, as validated in Lenovo's ThinkSystem server platform ecosystem. Compatible port types include QSFP28 interfaces operating at EDR (100Gb/s) signaling rates. Verify your switch and HCA firmware support passive copper DAC (Direct Attach Copper) cables at EDR speeds before deploying — some older firmware revisions require updates to enumerate DAC cables correctly alongside active optical modules. This cable is sourced from MX (Mexico) manufacturing and carries UNSPSC code 26121609, which classifies it under network communication cables for procurement and ERP integration purposes.

Installation Notes

Passive copper DAC cables are not interchangeable with active optical cables at the port level without reconfiguration — confirm your fabric management software recognizes the cable type. At 1 meter, bend radius management inside dense cable trays is the primary installation concern; avoid sharp bends near the QSFP28 connector boot to prevent signal degradation. Weight is 1.00 lb — negligible for rack cable management planning but worth noting when calculating total tray load in high-density deployments.
