Cable Construction and Routing
This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 37.5mm. 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.
Position Within the Length Range
LSWM1QSTK7A is the shortest of 2 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is LSWM1QSTK10A at 10m (33ft), adding 3m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.
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 26AWG; the minimum bend radius is 37.5mm; the jacket material is PVC (OFNR).
Network and Protocol Considerations
The intended application is determined by the host interface and protocol support. Listed interface and protocol references include 40G InfiniBand 8x DDR, 4x QDR, 10G/40Gigabit Ethernet, Fibre Channel. Confirm that the host firmware and port configuration support the same operating mode.
Length Selection and Installation Planning
The installation review for a 7m (23ft) link should include pathway length, support points, connector access and future maintenance. Route the complete copper assembly and both connector housings before attaching both ends, and avoid dragging it across connector panels. A final inspection should confirm that no latch, boot or jacket section carries unnecessary strain. The next verified reach is LSWM1QSTK10A at 10m (33ft), but selecting it before measuring the route would introduce additional slack to support.
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 LSWM1QSTK7A associated with 7m (23ft) throughout the order and receiving record.
H3C 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
Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. Delivery can be arranged by courier, air freight or sea freight, and goods may instead be handed to an appointed forwarder or shipped on the customer’s courier account.
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. Standard protective packing is used by default, with project documentation arranged when requested.
Frequently Asked Questions
Is this an original H3C cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies H3C LSWM1QSTK7A.
Does this order code cover multiple lengths?
No. LSWM1QSTK7A refers here to 7m (23ft). Every other verified length has a separate part number and page in the length list.
Are separate transceivers or patch leads required?
No. This is one complete direct-attach assembly. The ends are not detachable modules and should not be separated from the cable.
Can excess cable be folded into a compact bundle?
No. Use a supported, bend-safe service loop and observe the listed minimum bend radius. Do not crease the cable or tighten ties around the connector boots.
