2.2 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. Front­mounted 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-and­forward 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.

2.2.1 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

rear. Fan-driven cooling air flows left to right.

Fig. 2.2.1: Magnum 4K220CR “Reverse” model, front LEDs and
connections in Rear , AC power supply version

2.2.2: Magnum 4K220CR “Reverse” model, front LEDs and
connections in Rear , -48VDC optional power supply version

The Magnum 4K220CR-48VDC has the LEDs on the front panel, and all
the connecting ports and power feeds are in the back. This is convenient for rack­mounting where cabling is accessed from the rear of the rack while the operating status
LEDs are monitored from the front. Typically such arrangements are found in telco rack
installations.

The Magnum 4K220CR-48VDC is a dual-speed 10/100Mbps switch. The
switching capability allow the Magnum 4K220CR to support multiple workgroups
smoothly, each with its own switched 100Mbps or 10Mbps domain.

The 4K220CR may be equipped with an optional internal -48VDC power
supply (See Appendix A). There is an additional option of a dual-source -48V input
(See Appendix B). The DC power feed options and the high quality and versatility
make the Magnum 4K220CR a good high-availability choice for network traffic center
