Huawei S5735-S24T4X Out of Stock: S6730 or S6750 — Which Fits Your Project?

The Huawei S5735-S24T4X is a 24-port gigabit access switch with four 10GE SFP+ uplinks, a common specification for enterprise access-layer deployments. When this specific SKU goes out of stock, project timelines do not pause. Procurement teams need a fast decision: step up to the S6730 series for more performance, or stay closer to the original spec with the S6750. This guide explains when each alternative makes sense.

Part 1: What the S5735-S24T4X Actually Delivers

The S5735-S24T4X is positioned as a standard gigabit access switch with the following real-world profile:

• Downlink ports: 24×GE RJ45
• Uplink ports: 4×10GE SFP+
• Switching capacity: ~336 Gbps
• Packet forwarding: ~51 Mpps
• Typical deployment: Enterprise access layer, floor closet, small branch office

Organizations that specify this model usually need a reliable, cost-effective access switch with 10G uplink capability. It is not a high-performance core switch — it is a workhorse access-layer device. When it is unavailable, the substitute must cover the same role without over-provisioning or under-delivering.

Part 2: S6750 as Substitute — The Closest Match

The S6750 series sits within the same CloudEngine access-switch family as the S5735. It is the closest spec and price match when the S5735-S24T4X is out of stock. For buyers trying to keep the BOM stable and avoid extra redesign work, this is usually the lower-friction substitute path.

Why S6750 Is the Natural Substitute

• Same port configuration available. The S6750 offers models with 24×GE + 4×10GE SFP+, matching the S5735-S24T4X exactly.
• Same software platform. Both run Huawei's VRP operating system, which means configuration syntax, management tools, and feature behavior are consistent. This reduces operational friction during substitution.
• Similar price tier. The S6750 is positioned in the same mid-range access-layer segment, so the project budget impact is minimal.
• Lower risk for standardized deployments. If your organization already runs S5700-family switches, adding S6750 units does not introduce a new management platform or CLI syntax.

When S6750 Is NOT the Right Choice

• You need Layer 3 routing at the access layer. Some S6750 variants are Layer 2-focused. If your design uses access-layer routing, confirm the specific S6750 SKU supports the required protocols.
• You need higher uplink bandwidth. The S6750 tops out at 10GE uplinks. If your project is moving toward 25GE or 40GE access-layer uplinks, the S6730 is a better fit.

Part 3: S6730 as Substitute — The Performance Upgrade

The S6730 series is a step up from the S5700 family. It offers higher performance, more advanced features, and greater expansion flexibility, at a higher cost. It is a fit when the team is not only solving an out-of-stock problem, but also using the shortage as a chance to standardize toward a higher-bandwidth or longer-lifecycle platform.

When S6730 Is the Better Substitute

• You need 25GE or 100GE uplinks. The S6730 includes models with 25GE and 100GE uplink options, which the S5735 and S6750 cannot match. If your aggregation layer is upgrading to 25GE, the S6730 future-proofs the access layer.
• You need advanced features like MPLS, VXLAN, or EVPN. The S6730 supports these protocols in hardware, while the S5700 family may require software-based implementations or not support them at all.
• You are consolidating switch tiers. In some designs, the S6730 can serve as both access and light aggregation, reducing the total switch count in the rack.
• You want a 5-year platform. The S6730 is a newer platform with a longer expected support lifecycle. For organizations on 5-year refresh cycles, the higher upfront cost may be justified by avoiding an early replacement.

The Cost Reality

The S6730 typically costs 40–60% more than the S5735-S24T4X for a comparable port configuration. For projects where the S5735 was chosen specifically for cost control, the S6730 may exceed the approved budget. In those cases, the S6750 is the more fiscally responsible substitute.

Part 4: Side-by-Side Port and Feature Comparison

The S6750 matches the S5735-S24T4X closely in port count and role. The S6730 is a fundamentally different class of switch — closer to a data center access or aggregation platform than a standard floor-closet access switch.

Part 5: When to Choose Which Alternative

Part 6: Stock and Lead-Time Reality

When the S5735-S24T4X is unavailable, the stock status of substitutes becomes the practical deciding factor. In real projects, the issue is rarely just finding any available switch. The real task is confirming the exact port profile, software fit, accessories, and delivery timing so the replacement does not create a second compatibility problem after the PO is placed.

Current Availability Pattern

• S5735-S24T4X: Often on 4–6 week lead time during supply-tight periods. Stock fluctuates by region.
• S6750: Generally better availability due to broader production allocation. Often ships within 1–2 weeks for common SKUs.
• S6730: Availability varies by specific model. The S6730-H24X6C and similar high-performance models may have longer lead times due to specialized components.

What to Confirm Before Ordering

1. Exact model number and port configuration (e.g., S6750-24T4X vs S6750-48T4X)
2. Power supply type and redundancy requirements
3. Software license requirements (if any)
4. Whether the unit includes rack-mount kits
5. Regional compliance and power cord specifications

Router-Switch can support that next step with stock visibility, alternative SKU checks, BOM confirmation, and shortlist comparison across Huawei switch families. For time-sensitive access-layer deployments, confirming availability before finalizing the BOM prevents project delays and lowers mismatch risk before rollout.

FAQ

Can I replace S5735-S24T4X with S6750 without changing my network design?

In most cases, yes. The S6750 with 24GE+4SFP+ configuration is a direct port-for-port substitute. You may need to adjust VLAN assignments or port-channel configurations, but the physical connectivity remains identical.

Is the S6730 overkill for a standard office floor closet?

For a typical 24-port access switch serving 20–30 users, the S6730 is likely over-provisioned. The S6750 covers this use case at a lower cost. The S6730 makes sense when the access layer needs 10G+ downlinks or advanced routing features.

Do S5735, S6750, and S6730 use the same transceivers?

SFP+ transceivers (10GE) are generally compatible across all three series. However, the S6730 also supports 25GE SFP28 and 100GE QSFP28 transceivers, which the S5700 family does not. Always verify the specific transceiver part number against Huawei's compatibility matrix.

Can I mix S5735, S6750, and S6730 in the same network?

Yes, but with operational considerations. All three support standard protocols (STP, OSPF, VLANs), but feature behavior and CLI syntax may differ slightly. For organizations with limited network staff, standardizing on one family reduces troubleshooting complexity.

What happens if I buy S6750 now and upgrade to S6730 later?

This is a valid strategy if the S6750 is a temporary substitute. However, you will incur a second procurement cycle and potential configuration migration. For 3-year deployments, choosing the right platform upfront usually costs less than a mid-cycle swap.

Does Router-Switch stock all three models?

Router-Switch maintains inventory for the S5735, S6750, and S6730 series, with stock levels updated regularly. For current availability and lead times, send your requirements and timeline for a real-time stock check.

When the S5735-S24T4X is out of stock, the real choice is between preserving the original access-layer design with the least disruption, or using the shortage to justify a higher-capability platform. If you already know your port count, uplink direction, and deployment timeline, Router-Switch can help verify model fit, confirm stock, compare alternatives, and support a cleaner shortlist decision before you commit to the replacement order.
