Design and Hardware Features
Huawei’s design ensures a compact 1U form factor suited for rack mounting. The front panel offers easy access to all Ethernet, SFP+, stack, console, and USB ports. Dual stack ports located on the rear enable stacking up to 9 units at backplane speeds. Equipped with efficient fans and a nearly full‑range AC power module internally, the switch balances reliability with a low noise profile. The dimensions of 442 × 220 × 43.6 mm conform to 19‑inch rack standards.
Power over Ethernet (PoE+) Capability
With support for PoE+, this model is perfect for powering devices like IP phones, 802.11ac access points, or surveillance cameras. The switch can deliver up to 30 W per port under 802.3at, supporting a total PoE budget in line with enterprise setup needs.
Stacking and Scalability
The S5735‑L48T4XE‑A‑V2 supports stacking via two dedicated 12GE ports. Up to 9 switches can form a single logical device, simplifying management and offering high backplane bandwidth. This scalability allows network admins to grow capacity without adding complexity.
Layer 3 Routing and Network Protocols
Huawei equips this switch with robust L3 features including static route, RIP, OSPF, BGP, and multicast protocols like PIM‑SM. It efficiently handles inter‑VLAN routing, routing table, and ARP table with enterprise‑grade performance. Additionally, features such as VRRP, ACLs, DHCP snooping, and advanced security policies ensure operational integrity and secure deployment.
Quality of Service (QoS) and Traffic Management
Advanced QoS capabilities include:
Traffic classification and remarking
Supports DSCP and TC remarking, classification based on ACLs and protocols.
Queue scheduling
High‑priority traffic can be prioritized, with hardware queues applied.
Rate limiting
Both ingress and egress rate limiting across ports or flows, ensuring bandwidth control.
Congestion avoidance
Supports WRED and tail‑drop mechanisms. These QoS functions help maintain consistent application performance across converged networks.
High Availability and Redundancy
Huawei designed multiple mechanisms to ensure uptime:
Stack fault tolerance
Redundancy in stacking allows automatic failover from malfunctioning units.
Redundant power modules
Internal AC power module ensures backup from internal power switchover.
HVAC features
Fans and thermal controls adjust speeds to maintain optimal operation.
Security Features
Huawei integrates multiple security functions to protect network integrity:
ACLs and traffic filtering
Supports port‑based, VLAN‑based, and protocol ACLs for traffic control.
IP/MAC binding
Prevents MAC spoofing attacks by locking IP‑MAC combinations.
DHCP snooping and ARP inspection
Blocks rogue DHCP servers and ARP spoofing.
802.1X authentication
Port‑based authentication via RADIUS helps restrict access.
Management and O&M
The switch supports a wide array of management channels:
Command‑line interface
Fully featured CLI compatible with Huawei IOS‑like syntax.
Web GUI
Intuitive web management supported via Ethernet.
SNMP & RMON
Allows SNMPv2/v3 and RMON for monitoring.
Remote monitoring
NETCONF and Telnet/SSH offered for remote configuration.
USB interface
USB port lets users import/export configs or firmware.
Environmental and Physical Characteristics
Operating between 0 °C and 45 °C, and storing between –40 °C to 70 °C, this switch is suitable for typical data center or campus environments. Its heat dissipation of ~224 BTU/hr keeps rack temperatures stable, and the low‑noise internal fan enhances usability.
Typical Deployment Scenarios
▪ Edge access in campus networks supporting high‑density user or IoT device connections.
▪ Powering and connecting PoE devices such as wireless access points or surveillance systems.
▪ Building a scalable, stackable distribution layer with robust L3 and QoS features.
▪ Branch office core switch with strong security tools and management capabilities.
Comparisons with Other Models
Compared to non‑stackable variants like S5735‑L48T4S‑A‑V2, this model adds stack ports and 10GE uplink capabilities. It provides denser connectivity and scalability than smaller models like S5735‑L8T4S‑A‑V2. In contrast to PoE versions (e.g., L48P4XE), this unit focuses on higher uplink speed rather than PoE budget.
Firmware and Upgradability
Huawei supports this switch with regular firmware releases, offering bug fixes and feature enhancements. The USB port, web GUI, and CLI tools provide multiple options for firmware upgrades.
Cost of Ownership and Support
The switch offers strong performance per watt, consumes ~65 W without PoE, and heat is controlled effectively. Huawei’s global support and service agreements ensure long‑term operational reliability.
Conclusion
The Huawei S5735‑L48T4XE‑A‑V2 is a highly capable enterprise switch offering extensive connectivity, stacking, PoE+, robust L3/QoS, and security features. Its design balances performance, reliability, and scalability, making it ideal for modern campus, branch, and tower networks requiring future‑ready access infrastructure.
