Cisco Catalyst 4948E Switch Specifications and Details

The Cisco Catalyst 4948E is a fixed-configuration, Layer 2-4 Gigabit Ethernet switch designed for high-density, multilayer aggregation of high-performance, rack-optimized servers and workstations in data centers. Here's a breakdown of the key specs and details:

General Specifications:

• Form Factor: 1 Rack Unit (1RU)
• Number of Ports: 48 x 10/100/1000 Base-TX RJ45 Downlink ports
• Uplink Ports: 4 x SFP+ ports (supporting 1 Gigabit Ethernet or 10 Gigabit Ethernet with SFP+ modules)
• Switching Capacity: 176 Gbps
• Throughput: 131 Mpps (IPv4), 110 Mpps (IPv6)
• Power Supply: Optional internal AC or DC 1+1 hot-swappable power supplies
• Cooling: Hot-swappable fan tray with redundant fans (front-to-back or back-to-front airflow options)
• Management: Command Line Interface (CLI), Web interface

Additional Details:

• Layer Support: Layer 2 (Data Link Layer), Layer 3 (Network Layer), Layer 4 (Transport Layer)
• Security Features: Access Control Lists (ACLs), IEEE 802.1X port-based authentication, VLANs for network segmentation
• Quality of Service (QoS): Prioritizes traffic for time-sensitive applications like voice and video
• Jumbo Frames: Supports larger packet sizes for improved performance with certain applications

Benefits:

• High Performance: Delivers wire-speed performance for demanding workloads.
• Scalability: Offers uplink flexibility with support for 1 Gigabit or 10 Gigabit Ethernet connections.
• High Availability: Hot-swappable power supplies and fans ensure continuous operation.
• Advanced Features: Security, QoS, and VLAN capabilities for robust network management.
• Compact Design: Fits conveniently into a single rack unit, saving space in data centers.

Applications:

• Data center server aggregation
• Top-of-Rack (ToR) deployments
• High-performance computing environments
• Network core and distribution layers in smaller networks

Important Notes:

• SFP+ modules are required for 10 Gigabit Ethernet uplink connections (sold separately).
• The switch itself does not come with SFP+ modules. Choose compatible SFP+ modules based on your specific network needs (e.g., fiber optic or copper).
• For detailed information on compatible SFP+ modules, refer to Cisco's compatibility matrix or consult your specific vendor.
