H3C S5135S-SI Green Intelligent Gigabit Ethernet Switch, High-Density Access & Convergence Layer, Support IPv6 & ERPS ≤50ms Ring Protection, IRF Stacking, Secure Enterprise Networking

The H3C S5135S-SI is a next-generation high-performance, high-port density, high-security intelligent managed Gigabit Ethernet switch developed by H3C Technology Co., Ltd. Utilizing industry-leading ALIC technology, it supports IPv4/IPv6 dual-stack management and forwarding, along with comprehensive management and security features.

Primarily positioned at enterprise and campus network access and aggregation layers, the S5135S-SI meets high-density gigabit access requirements with fixed gigabit uplinks, enabling high-performance end-to-end IP network solutions when combined with other H3C products.

The H3C S5135S-SI series supports innovative IRF (Intelligent Resilient Framework) technology, enabling multiple switches to form a logically independent entity for building highly reliable, scalable, and manageable intelligent networks.

The S5135S-SI series supports single-port multi-authentication functionality, allowing different client authentication methods (MAC address, 802.1X, web portal) on the same port. Features include:

• Guest VLAN functionality for controlled resource access
• Comprehensive ARP defense with detection and rate limiting
• EAD (Terminal Access Control) integration with background systems
• SSH V2 encryption for secure management

Advanced QoS capabilities including L2-L4 packet filtering, flow classification based on multiple criteria, flexible queue scheduling (SP, WRR, SP+WRR), bidirectional ACL, traffic supervision CAR function, and comprehensive port/stream mirroring for network monitoring and troubleshooting.

Support for SNMPv1/v2/v3, CLI, WEB, and TELNET management with SSH2.0 encryption. BIMS protocol support enables automatic configuration download for zero-configuration deployment. Multiple reliability protections including over-current/voltage/temperature protection, power/fan monitoring, and comprehensive link-level reliability technologies (LACP/STP/RSTP/MSTP).

Energy-efficient design featuring auto-power-down for inactive ports, EEE energy-saving functionality, and compliance with EU RoHS environmental standards. Innovative architecture and energy-saving chips deliver the lowest power consumption for gigabit switches.

Intelligent power supply system integrating AI technology for:

• Smart PD power supply management
• Intelligent power and alarm management
• Enhanced PoE security
• Fast reboot and perpetual PoE functionality
• Long-distance PoE support

Ideal for access layer deployment in large campus networks, providing high-density gigabit access with PoE functionality for IP phones, WLAN APs, and other PD devices. Built-in network management software supports unified management of wireless, switches, and routers for simplified operation in small CT scenarios.
