Versatile PoE+ Power for IP Devices

The CloudEngine s5735‑l48p4xe‑a‑v2's PoE capabilities are significant. With its built-in AC power module alone, it delivers ~380 W PoE power—sufficient for around 12 IEEE 802.3at (30 W) devices. By installing a 1000 W external power module (PAC1000S56‑EB), the switch can supply up to 864 W (220 V input) or 774 W (110 V input), enabling full support for up to 48 PoE devices under IEEE 802.3af (15.4 W) or 25–28 devices under 802.3at (30 W).

Flexible Ethernet Networking Features

Layer‑2 Protocols & Resilience

▪ Rapid Spanning Tree (RSTP), Multiple Spanning Tree (MSTP), and Smart Ethernet Protection (SEP) with sub-50 ms convergence.
▪ Ethernet Ring Protection Switching (ERPS) per ITU‑T G.8032 for ultra-fast ring convergence.
▪ Smart Link redundancy for uplink backup and enhanced device reliability.

Layer‑3 Routing Capabilities

▪ Supports IPv4 and IPv6 static routing, RIP, OSPF, VRRP, and policy-based routing (PBR).
▪ Multicast protocols: IGMPv1/v2/v3 snooping and proxy, PIM‑DM, PIM‑SM, MSDP, and RPF for IPv4 and IPv6.

Security and Access Control

User Authentication

▪ Supports 802.1X, MAC-based, and hybrid user authentication with dynamic policy enforcement (VLAN/QoS/ACL).

Anti‑Attack Mechanisms

▪ Defends against DoS floods (SYN, Smurf, ICMP, Land), DHCP spoofing/flood, ARP spoofing, and IP/MAC spoofing.
▪ DHCP snooping with trust-based DHCP binding, and strict ARP learning to prevent ARP cache exhaustion and spoof attacks.

Intelligent Operation & Maintenance (O&M)

Zero‑Touch Deployment

▪ Huawei Easy Operation supports USB-based zero‑touch deployment, batch configuration, remote upgrades, and fault-tolerant replacement.

Telemetry & Network Insight

▪ Real-time telemetry integrated with Huawei CampusInsight (via iMaster NCE‑Campus) for proactive fault detection and service assurance.

▪ Enhanced Media Delivery Index (eMDI) for audio/video service monitoring.

Intelligent Upgrade

▪ Automated firmware downloads and upgrades from Huawei Online Upgrade Platform (HOUP), with version preloading for minimal service interruption.

Scalability via iStack Stacking

The s5735‑l48p4xe‑a‑v2 supports iStack, allowing multiple switches to be grouped into a logical unit. Benefits include redundancy, simplified management with a single IP for the stack, and aggregated uplink performance.

CloudEngine s5735‑l48p4xe‑a‑v2 within the CloudEngine Family

Within Huawei’s CloudEngine S5735‑L V2 series, the s5735‑l48p4xe‑a‑v2 stands out as an advanced model optimized for PoE deployments and L3 routing. It complements models like L48P4S-A-V2 by adding higher uplink bandwidth and stacking flexibility.

Ideal Use Cases and Network Scenarios

▪ Campus and Enterprise Access Layer: With high port density and rich routing features, this switch is ideal for campus edge deployments supplying VoIP phones, wireless APs, and IP cameras over PoE.
▪ Mid-range Aggregation: Thanks to its 10 GE uplinks and stacking, it's suitable for aggregation nodes combining multiple access switches.
▪ Video and Smart Applications: Supports sustained power for CCTV and industrial PoE endpoints, with real-time monitoring via eMDI and telemetry systems.

FAQ

What is the maximum number of PoE ports supported?

Using a 1000 W PoE module, you can power up to 48 IEEE 802.3af ports or 25–28 IEEE 802.3at ports depending on AC input voltage. Without it, the internal module supports up to 12 PoE+ (802.3at) devices.

Does the switch support stacking?

Yes, it includes two 12 GE stacking ports and supports iStack for multi‑switch redundancy and capacity expansion.

Can it handle IPv6 routing?

Absolutely. It supports IPv6 static routing, RIPng, OSPFv3, VRRP6, DHCPv6, and multicast protocols like MLD and PIM for IPv6.

What security measures are in place?

Includes port-based authentication (802.1X, MAC, hybrid), ACL, DHCP snooping, strict ARP, DoS attack defense, and attack screening (e.g., SYN floods, Smurf).

Is remote management supported?

Yes. It supports SNMP v1/2/3, CLI, SSHv2, web management, RMON, and cloud-based configuration/monitoring via Huawei’s iMaster NCE‑Campus.
