▪ USB 2.0 type‑A port, supports up to 128 GB USB flash drives for file transfer and firmware upgrade

LED Indicators

▪ Similar to S5735‑L12P‑series switches, but without PoE mode indicator
▪ USB indicator absent compared to PoE variants

Performance Characteristics

The S5735‑L24T4S‑A delivers forwarding performance of approximately 42 Mpps and switching capacity of 56 Gbps with system capacity up to 336 Gbps. It supports stacking using any GE port (10/100/1000BASE‑T or 1000BASE‑X) in firmware V200R019C10 or later.

Key Features & Benefits

▪ Flexible Ethernet Networking: supports STP/RSTP/MSTP, Huawei SEP (Smart Ethernet Protection) and ITU‑T G.8032 ERPS with protection switching in<50 ms
▪ Smart Link: uplink redundancy by connecting to multiple aggregation switches for enhanced reliability
▪ Ethernet OAM: IEEE 802.3ah/802.1ag for fast link fault detection
▪ Diversified Security Control: supports 802.1X, MAC and hybrid authentication, dynamic VLAN/QoS/ACL policy delivery, defenses against SYN flood, DHCP spoofing, ARP spoofing, plus DHCP snooping and strict ARP learning
▪ Easy Operation & Maintenance: Huawei Easy Operation including zero‑touch deployment, batch config and USB‑based provisioning; supports CLI, SNMP V1/V2/V3, SSH, web, RMON, log hosts, traffic stats, GVRP, MUX‑VLAN, VBST and more
▪ iStack: stackable via electrical ports, forming logical switch for redundancy and scalability, simplified management across member switches
▪ Traffic Analysis & Telemetry: supports sFlow sampling and CampusInsight analytics for real‑time status and fault detection
▪ Intelligent Upgrade & Cloud Management: supports one‑click upgrade via HOUP, Huawei cloud/on‑premise management, and OPS programmable via Python scripting for automated maintenance

Deployment & Use Scenarios

Ideal for enterprise campus network access where silent operation (fanless design) and gigabit‑to‑desktop connectivity are required. Its robust security, stacking, and management capabilities make it suitable for medium‑sized offices, education campuses, and branch environments. USB provisioning and high availability features simplify deployment and reduce O&M overhead.

Comparison with V2 Variant

The V2 variant of the model (S5735‑L24T4S‑A‑V2) differs in that it includes built‑in fans for forced‑air cooling, meeting desktop‑class noise levels but louder at startup, with typical power consumption at ~26 W vs ~32.7 W for the A1 variant. Weight and dimensions remain similar, but airflow layout is different (fans vs fanless).

Часто задаваемые вопросы

Q: Does the switch support PoE?

No – the S5735‑L24T4S‑A is a non‑PoE model; PoE variants in the series include P models (e.g. L24P4S).

Q: Can I stack multiple units?

Yes – stacking is supported via any GE port on firmware versions V200R019C10 or higher.

Q: Is it truly fanless?

Yes – the A and A1 variants use natural heat dissipation without fans, suitable for noise‑sensitive environments.

Q: What uplink optics are supported?

It supports standard 1000BASE‑X SFP optical modules (GE eSFP, CWDM, etc.).

Q: How to upgrade firmware or configurations?

Use the USB 2.0 port with flash drives up to 128 GB, or deploy via Huawei Easy Operation tools for batch remote upgrades.

Q: What network protections does it offer?

Includes DHCP snooping, strict ARP learning, various DoS attack protections, MAC/IP spoofing defense, and authentication (802.1X, MAC, hybrid, portal).
