The Cisco Catalyst 4900M is a premium semi-modular switch designed for high-performance data center top-of-rack deployments and collapsed core architectures. It offers a unique blend of fixed ports and modular flexibility, allowing for a seamless transition from 1Gbps to 10Gbps networking.
SKYRS Pakistan specializes in the procurement and technical lifecycle management of the 4900M series, providing high-density switching solutions to the local enterprise market.
The 4900M architecture is built for low latency and high availability, featuring hot-swappable power supplies and fans.
| Feature | Specification |
| Base Ports | 8 Fixed wire-speed 10Gbps (X2 ports) |
| Expansion Slots | 2 Half-slots for optional modules |
| Switching Capacity | 320 Gbps |
| Throughput | 250 Mpps |
| Form Factor | 2 RU (Rack Unit) |
| Latancy | Extremely low (< 2 microseconds) |
| Redundancy | 1+1 AC or DC Power Supplies; Hot-swappable fan tray |
SKYRS provides the base chassis along with the specialized “half-card” modules to customize your port density:
WS-C4900M: The core chassis with 8 fixed 10GbE X2 ports.
WS-X4908-10GE-V3: 8-port 10GbE (X2) half-card module.
WS-X4904-10GE-V3: 4-port 10GbE (X2) half-card module.
WS-X4920-GB-RJ45: 20-port 10/100/1000 (RJ45) half-card module for copper connectivity.
WS-X4906-10GE-SFP: 6-port 10GbE (SFP+) module for modern fiber flexibility.
Given its 2RU size and high-performance nature, installation requires specific environmental considerations:
Airflow Management: The 4900M uses side-to-back airflow. Ensure that the rack sides are not obstructed to prevent thermal throttling.
Modular Insertion: Before powering on, insert your chosen expansion modules (e.g., the 20-port copper card) into the two front slots and tighten the captive screws.
Power Connectivity: Connect both power supplies to independent circuits if possible. The switch will load-balance across both units.
X2 to SFP+ Conversion: If you are using modern SFP+ transceivers (like the SFP-10G-SR), SKYRS recommends the CVR-X2-SFP10G OneX converter module to ensure compatibility with the 4900M’s native X2 ports.
The C4900M runs Cisco IOS Software, offering a familiar interface for network administrators.
