ExtremeSwitching X440-G2-48T-10GE4 48-Port Gigabit Ethernet Switch with 10GbE Uplink Capability

1. Product Overview

The ExtremeSwitching X440-G2-48T-10GE4 is a high-performance, scalable edge switch designed for modern enterprise networks. It features 48 x 10/100/1000BASE-T ports, 4 x 1GbE SFP combo ports, and 4 x upgradable 1GbE/10GbE SFP+ uplink ports. Powered by the resilient ExtremeXOS operating system, this switch delivers advanced Layer 2 and Layer 3 functionality, PoE+ support, and robust security features. It is ideal for campus, branch, and data center edge deployments.

2. Key Features

• 48 x Gigabit Ethernet RJ-45 ports + 4 x combo SFP ports
• 4 x 1GbE SFP+ uplinks upgradeable to 10GbE via software license
• Support for IEEE 802.3at PoE-Plus and 802.3af PoE
• SummitStack-V stacking for up to 8 units
• Role-based policy enforcement and granular ACLs
• ExtremeCloud™ compatible for cloud-based management
• Redundant power supply (RPS) support
• Energy Efficient Ethernet (EEE) compliance

3. Supported Technologies & Standards

• IEEE 802.3ab, 802.3z, 802.3ae, 802.3at, 802.3az
• IPv4/IPv6 routing
• Audio Video Bridging (AVB) – IEEE 802.1
• Bidirectional Rate Limiting (8 Kbps granularity)
• ExtremeXOS with Advanced Edge License support

4. How It Works

The X440-G2-48T-10GE4 operates as a full-duplex non-blocking switch, forwarding traffic at line rate with less than 4 microseconds latency. It uses hardware-based ACLs and policy profiles to enforce security and QoS rules. The SummitStack-V technology allows multiple switches to operate as a single logical unit, simplifying management and increasing resiliency.

5. Applications

• Enterprise campus and branch networks
• IP surveillance and physical security systems
• Wireless access point aggregation
• VoIP and unified communications
• Edge data center connectivity
• Education and healthcare networks
