This data sheet provides a technical overview of the Cisco Catalyst 4948E and 4948E-F Ethernet Switches. These platforms are optimized for high-performance, low-latency Layer 2 and Layer 3 data center switching, making them the premier choice for software houses and call centers in Pakistan through SKYRS.
Cisco Catalyst WS-C4948E Series Overview
The WS-C4948E is a specialized “Top-of-Rack” (ToR) switch that delivers wire-speed throughput and low latency for data-intensive applications. Despite being branded under the Catalyst line, its architecture shares Nexus-class attributes such as high-performance buffers and front-to-back or back-to-front cooling options. It is designed to handle the rigorous demands of server aggregation and high-density workstation connectivity.

Hardware Variants Available at SKYRS
SKYRS maintains a comprehensive inventory of the 4948E series to match the specific airflow and power requirements of Pakistani data centers.
WS-C4948E: The standard variant featuring front-to-back airflow (Port-side intake).
WS-C4948E-F: The specialized variant featuring back-to-front airflow (Port-side exhaust), ideal for hot-aisle/cold-aisle containment systems.
WS-C4948E-BDL: Bundle options including dual AC power supplies and high-performance fan trays.
Power Options: SKYRS stocks both 300W AC and 300W DC power modules to ensure compatibility with diverse power infrastructures.
Deployment and Installation Guidelines
To achieve the best results in high-density environments, the SKYRS technical team follows these deployment standards:
Physical Installation:
Airflow Alignment: Ensure the switch airflow (E or E-F variant) matches your rack’s existing cooling pattern. Installing the wrong variant can lead to thermal recirculating and hardware failure.
Rack Mounting: The unit is 1RU and includes heavy-duty rack-mount brackets. For server racks in Karachi or Islamabad, SKYRS provides rear-support rails to ensure the chassis remains level.
Cable Management: Given the 48-port density, SKYRS recommends using high-quality Cat6a patch cords for the copper ports and Cisco SFP-10G-SR modules for 10G uplinks.
Power and Grounding:
Redundancy: Always populate both power supply slots. SKYRS configures the switch to load-share across both modules for maximum efficiency.
Grounding: Utilize the dual-hole grounding lug on the rear of the chassis to protect the 17.5 MB buffer logic from static discharge.
Configuration and Service Availability Only at SKYRS
As the leading Cisco equipment series distributor in Pakistan, SKYRS provides specialized configuration and staging services for the 4948E series.
Exclusive SKYRS Services:
Latency Optimization: We pre-configure the switch for “Low Latency” mode, essential for high-frequency trading or real-time VoIP environments like call centers.
OS Hardening: SKYRS technicians load the latest “Gold Star” Cisco IOS and apply security templates to protect against broadcast storms and unauthorized access.
L3 Routing Staging: Configuration of advanced routing protocols (OSPF/BGP) and VRF-lite to segment call center traffic from back-office data.
Hardware Stress Test: Every WS-C4948E undergoes a 24-hour traffic-load burn-in at our Karachi facility to ensure the dynamic buffers and SFP+ ports are 100% functional.
Local Warranty & Support: Immediate hardware replacement and 24/7 technical troubleshooting are available exclusively through the SKYRS regional hubs.
Note: Due to the specialized nature of the E-F (Back-to-Front) airflow variants and the required S-Class firmware staging, these units are available exclusively through the SKYRS distribution network in Pakistan.
