Specifications

Power and Thermal Planning

The rated power consumption is ≤0.5W. Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.

Length Selection and Installation Planning

The 5m (16ft) length gives 81Y8297 more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the ACC specification and host support must still match the intended link.

Position Within the Length Range

81Y8297 occupies the middle of this family between 45W2408 at 3m (10ft) and BNT BN-SP-CBL-10M at 10m (33ft). It adds 2m over the shorter option for extra routing clearance, while the next longer version adds another 5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

Structured Pathways and Serviceability

Treat the direct-attach assembly as part of the permanent pathway plan even when the link is expected to be temporary. Follow the intended horizontal and vertical managers, maintain the specified bend radius and leave service access around both ports. A small, supported service allowance is preferable to excess slack concealed inside a rack or placed under cable-tie pressure. For this assembly, the listed conductor specification is 28AWG; the minimum bend radius is 30mm; the stated power consumption is ≤0.5W; the jacket material is PVC (OFNR).

Cable Construction and Routing

This assembly uses 28AWG conductors, PVC (OFNR) jacket, minimum bend radius 30mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.

Network and Protocol Considerations

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include 1x InfiniBand QDR, DDR, SDR, 10 Gigabit Ethernet, Fibre Channel. Confirm that the host firmware and port configuration support the same operating mode.

Ordering Information

Include the part number, fixed length, quantity and required pathway or rack grouping in the order information. The host model and firmware release are useful for change-controlled deployments. Different lengths should remain separate order lines so delivered labels and packing records agree with the pathway plan. Keep 81Y8297 associated with 5m (16ft) throughout the order and receiving record.

IBM Compatibility and Factory Testing

Verification covers the physical connectors, expected host identity and an operating link with available diagnostic indications. We distinguish this complete check from a simple continuity test. Platform model and software release can be reviewed in advance where the installation has strict documentation or change-control requirements. The check includes link stability and diagnostic indications, followed by a final inspection of both ends.

Shipping and Lead Time

Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. Worldwide courier services are available, with air or sea freight for consolidated shipments; freight-collect delivery and coordination with a customer’s logistics provider can be arranged.

Quality Assurance and Packaging

After connector inspection and link verification, the assembly is coiled without tight bends and packed with end protection. Labels can cross-reference the customer cable schedule, OEM part number and length. This supports both receiving checks and later moves, adds or changes. Neutral packaging and customer-specific packing documentation are available on request.
