Nortel Ethernet Routing Switch 4548GT-PWR Features

The Nortel Ethernet Routing Switch 4548GT-PWR (AL4500E14-E6) is a versatile, stackable Layer 3 switch engineered for enterprise networks. Specifically designed for wiring closets and edge deployments, this switch seamlessly integrates robust connectivity, advanced security, and Power over Ethernet (PoE) capabilities. Consequently, it delivers exceptional performance, scalability, and energy efficiency to meet modern business needs.

Key Features

1. High-Density Gigabit Connectivity

To begin with, the 4548GT-PWR provides 48 RJ-45 Gigabit Ethernet ports (10/100/1000Base-T), ensuring rapid data transfer for bandwidth-heavy applications. Moreover, it includes 4 shared SFP ports for flexible fiber uplinks, thereby extending network reach and enhancing connectivity options.

2. Power over Ethernet (PoE)

In addition, the switch complies with IEEE 802.3af PoE standards, enabling it to power devices such as IP phones, wireless access points, and security cameras directly through Ethernet cables. As a result, this simplifies installations, reduces cabling expenses, and lowers operational costs by eliminating separate power sources.

3. Stackable and Scalable Design

Furthermore, the 4548GT-PWR features 2 dedicated stack ports, supporting resilient stacking for up to 8 units. This scalability ensures seamless network expansion. Coupled with a 320 Gbps switching capacity and virtual hot-swap capability, it guarantees minimal downtime, thereby enhancing network reliability for mission-critical applications.

4. Advanced Security Features

Equally important, the switch incorporates robust security measures, including IEEE 802.1X-based EAP, RADIUS, TACACS, and Secure Shell v.2 for secure authentication. Additionally, MAC address filtering and DHCP snooping safeguard against unauthorized access, ensuring only trusted devices connect to the network.

5. Comprehensive Management

Moreover, the 4548GT-PWR supports RMON, Telnet, HTTP, and SNMPv3 for flexible management. Similarly, VLAN support (IEEE 802.1Q) enables efficient network segmentation, while QoS (Quality of Service) prioritizes traffic, thereby optimizing performance for voice, video, and data convergence.

6. Energy Efficiency

In terms of sustainability, the switch employs energy-saving technologies, significantly reducing operational costs. Consequently, it supports eco-friendly deployments, making it an ideal choice for businesses aiming to minimize their environmental impact.

7. Additional Features

Lastly, the switch offers Jumbo Frames support for efficient data transfers, IPv6 readiness for future-proofing, and auto-negotiation with flow control for optimized performance. Additionally, USB and console ports simplify management tasks.

In conclusion, the Nortel 4548GT-PWR combines reliability, scalability, and cost-efficiency, making it a premier solution for enterprises seeking secure, high-performance, and convergence-ready networking.
