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.
