Product Description - Magnum 4K220CR Switches 

 

Magnum 4K220CR Switches boost the performance of large Ethernet LANs, 

with economical solution per switched port. The Magnum 4K220’s provide the 

switching speed and the reliability to support multiple workgroups, each with its own 

switched 100Mbps or 10Mbps domain, for increased network performance. 

Designed specifically for the vertical rack space environment, the Magnum 

4K220CR used in departments with multiple workgroups, in remote offices and in 

network traffic centers or multi-system power users, the Magnum 4K220CR witches are 

easy to install and use. Addresses of attached nodes are automatically learned and 

maintained, adapting the switching services to network changes and expansions. Front-

mounted LEDs provide status information on each port. The Magnum 4K-Series 

Switches provide high performance plug-and-play operation in convenient rack-mount 

packages. 

The reverse port enclosure of Magnum 4K220CR switches are designed to 

provide ease of maintainability to the larger network. The 40-port density in a 1U rack 

mount “reverse” package is obtained by dedicating the front of the unit to the LED 

indicators, and the rear side of the unit to wiring and power supply connection. 

The Magnum 4K220CR switches are non-blocking on all ports and include 

2MB dynamic packet buffers and a 4K-node address table for advanced performance as 

well as to support large networks. The Magnum 4K-Series Switches, with store-and-

forward switching, filter all faulty packets to minimize traffic congestion. 

The Magnum 4K220CR switches comes along in a rugged metal enclosure 

with an auto-ranging power supply for operation with standard AC power worldwide.

Magnum 4K220 Switch chassis  

 

Magnum 4K220 Switches come with a 40-switched  RJ-45 ports enclosed in a 

rack-mountable chassis and ready to install in any of the ETSI (19”) and TELCO (23”) 

environments by the available brackets. 

The LED status indicators and the manual switches are located on the front 

panel of Magnum 4K220 Switches. There are Full-duplex/Collision (FDX/COL), 

Link/Activity (LINK/ACT) and (100/10) LED indicators for each 10Mbps and 

100Mbps domain, for visual indication of the operating status of each domain. The IEC 

standard AC power connector (and a manual ON - OFF power switch) is located at the
