Основные моменты проекта

Advanced Layer 2/Layer 3 Capabilities

The switch supports key Layer 2 and Layer 3 features that make it suitable for enterprise access or aggregation. It supports protocols such as OSPF, IS-IS, BGP and VRRP for routing. IPv6 support (dual-stack, RIPng, OSPFv3) is also built in, aiding migration. Additionally, it supports IGMP snooping, PIM SM/DM/SSM for multicast applications.These features happen alongside high port density, making the device capable of handling large access deployments with strong uplinks and stacking.

Flexibility & Scalability

With stacking ports (2 x 12 GE), the switch can be part of an iStack configuration, resulting in a logical device made up of multiple physical units. This simplifies management and improves scalability. The presence of both gigabit downlinks and 10 GE uplinks means it can serve large access layer roles feeding aggregation or distribution.

Security & Network Protection

The device includes a range of security mechanisms: MAC address authentication, 802.1X, dynamic policy delivery (VLAN, QoS, ACLs), DHCP snooping, strict ARP learning, and anti-DoS protections (SYN/Smurf/Land floods). These safeguards help protect edge networks where endpoint devices are numerous and potentially vulnerable.

Reliability & High Availability

Reliability is also a strong point: the switch supports redundant power supply modules (1+1), mixed AC/DC module usage, Smart Link for uplink backup, and fast protection protocols such as ERPS (50 ms switching). The cooling design and metal chassis also contribute to durability in enterprise environments.

Operational Efficiency & Manageability

Huawei emphasises simplified O&M: zero-touch deployment, USB-based configuration, batch upgrades, telemetry for real-time data, and open programmability via Python (OPS). Together these features decrease deployment and ongoing maintenance costs while enabling modern network operations and automation.

Energy Efficiency & Reduced Footprint

With a typical power consumption of 39 W (for the device without heavy load) and compact 1U form factor, the S5735-S48T4XE-V2 is well-suited to dense racks and power-sensitive environments. It has forced-air cooling aimed at efficient thermal design.

Use Case Scenarios

The S5735-S48T4XE-V2 is ideal for a variety of deployment scenarios: 

▪ Campus access layer – High-density 1 Gb ports serve user devices, while the 10 GE uplinks aggregate traffic toward distribution or core switches. 

▪ Campus aggregation layer – For smaller enterprises, the device’s routing capabilities allow it to serve as both access and aggregation switch, simplifying network tiers. 

▪ Branch/Metro access – With full Layer 3 and IPv6 features, the switch can operate as an access device in a metropolitan area network (MAN) or branch environment. 

▪ Future-proof upgrade path – The combination of 1 Gb access ports and 10 GE uplinks ensures the network can scale while preserving existing wiring.

Installation & Deployment Considerations

When deploying the S5735-S48T4XE-V2, here are some practical considerations:

Rack space & mounting: The unit is 1 U and wide (442 mm). Ensure front-to-rear airflow and rack depth accommodate the maximum 446 mm depth.

Cooling & airflow: The built-in dual fans must have proper intake (left, right, front) and exhaust (rear) clearance to avoid thermal issues.

Power redundancy: For high availability, plan for two power modules (1+1) or more if stacking. Mixing fan- and non-fan power modules is disallowed.

Stacking configuration: If using iStack, ensure stack ports are connected and software versions are aligned. Stacking allows management as a logical device and increased scale.

License & software: The switch supports Huawei’s traditional licensing and N1 (IDN One Software) mode, offering feature flexibility.

Security policy alignment: Given the rich security features, align ACLs, DHCP snooping, and ARP protection with your network access policy to fully leverage the device.

Strengths & Limitations

Strengths: Very high port density of 48 gigabit access ports and 4 x 10 GE uplinks.Strong Layer 3 and IPv6 support makes it more than just a basic access switch.Rich management and O&M features suitable for modern network environments.Redundancy capability and reliable hardware for enterprise usage.

Limitations: It lacks built-in PoE support in this “T” model variant (the “P” or “U” models provide PoE or PoE++).While capable for access/aggregation, it may not match very high-performance core switches (which offer 40 GE/100 GE uplinks) in very large networks.Ensure stack design and licensing plan are in place if you plan growth beyond a single unit.

Summary & Recommendation

In summary, the Huawei CloudEngine S5735-S48T4XE-V2 is a robust, feature-rich enterprise-class switch offering very good port density, strong routing and IPv6 support, and modern management features. It is well-suited for campus access and aggregation layers where 1 Gb access networking is required, but where uplinks and routing features must also be modern and scalable.If your environment demands 48 gigabit access ports, and you don’t need PoE in that specific switch (or you use PoE variants elsewhere), this model provides excellent value. For deployments needing PoE, consider the variant S5735-S48P4XE-V2 instead.For those designing networks with future growth in mind, the strong uplinks, stacking support, and modern features of this switch make it a reliable investment.

Frequently Asked Questions (FAQs)

Q1: Does the S5735-S48T4XE-V2 support PoE?

No — the “T” model does not include Power over Ethernet. If you need PoE+ or PoE++ support, you should look at the S5735-S48P4XE-V2 (PoE+) or S5735-S48U4XE-V2 (PoE++ up to 90 W).

Q2: Can the switch be stacked with other units?

Yes — the switch supports iStack technology with dedicated stack ports (2 x 12 GE) enabling multiple units to behave as a single logical switch for scalability and simplified management.

Q3: Does it support IPv6?

Yes — it supports IPv4/IPv6 dual-stack, IPv6 routing protocols such as RIPng, OSPFv3, IS-ISv6 and helps enterprises transition from IPv4 to IPv6.

Q4: What kind of power redundancy does it support?

The model supports 1+1 (single or dual) plug-in power modules. It also supports mixing AC and DC power modules (depending on configuration) although fan and non-fan modules cannot be mixed.

Q5: Is the switch suitable for aggregation or distribution layer?

Yes — while primarily an access/aggregation switch, its Layer 3 capabilities and uplinks make it feasible for smaller aggregation or distribution roles in enterprise networks.

Q6: What are the physical and power requirements I should be aware of?

You’ll need a rack of at least 1 U height, ≈442 mm width, and ensure depth clearance up to ~446 mm with protrusions. Cooling airflow must be maintained front-to-back or side-to-back, and the power modules and fans require proper ventilation. Typical power consumption is ~39 W, but plans for higher peaks are prudent.

Iii. Выводы и рекомендации

To wrap up, the Huawei S5735-S48T4XE-V2 strikes a strong balance between cost, performance, and feature set. It delivers enterprise-grade access/aggregation switch capability with modern Layer 3, IPv6, security, and stacking features — yet stays within a manageable power, size, and cost envelope. For network architects building campus networks with rich access needs, this is a solid choice.
