Magnum 4K16 16-port
Ethernet 10/100 Switch,
Boosting the performance
of medium sized Ethernet
LANs with the flexibility of
both twisted-pair and
fiber-switched ports
Magnum 4K16 Switches
provide 16 switched ports,
with two ports that can be
up to 100 Mb fiber. All ports
are switching and support
full- and half-duplex as well
as auto-negotiation on TP
ports. Plus, they are easy
to install and use.
• High performance non-blocking operation,
plug-and-play installation for switching
services, transparent to system software
• Has a compact 1U package for installation
in rack cabinets, with metal case and autoranging internal power supply
• Available options include -48VDC, 24VDC,
and 125VDC power, dual-source, NEBS and
ETSI certification, “Reverse” rack-mount,
ETSI and 23” Telco brackets, Class B EMI and
extended temperature range operation
Magnum Model 4K16 Switches boost the
performance of medium-sized Ethernet LANs,
with the flexibility of both twisted-pair and
fiber switched ports. Fiber ports may number
zero, one or two, and a variety of user selected
fiber connector types may be configured. The
Magnum 4K-Series provides the switching
speed and the reliability to smoothly support
multiple workgroups, each with its own switched
100Mb or 10 Mb domain, for increased network
The Magnum 4K16 Switch offers application
flexibility with a series of optional fiber
connector types. Users may choose a fiber port
type (100 Mb FX-ST, SC, MTRJ) and fiber cable
mode (multi-mode and single-mode) which
are configurable using a family of 1- or 2-port
modules. The twisted-pair ports are 10/100 autonegotiating.
Magnum 4K16 Switches are easy to install
and use. Addresses of attached nodes are
automatically learned and maintained, adapting
the switching services to network changes and
expansions to provide plug-and-play operation.
LEDs provide status information on each port.
“Reverse” models with front-mounted ports and
LEDs, or with front-mounted LEDs, rear ports
and power connections, are also available.
The Magnum Model 4K16 Switches are nonblocking on all 16-ports, and include large 2 MB
packet buffers for advanced performance, even
with unbalanced loads. The dynamic 2K-node
address table allows the 16-port Magnum 4K16
to support medium-sized networks. The entire
Magnum 4KSeries, with store-and-forward
switching, filters all faulty packets to minimize
traffic congestion.
Magnum Model 4K16 Switches are provided
in a rack-mountable package and have a
rugged metal case and an auto-ranging power
supply for operation with standard AC power
worldwide. “Carrier Class” and “Industrial
Strength” models with optional DC input power
features are also available. The 4K-Series and
all other Magnum products are designed and
manufactured in the USA and backed by a
three-year warranty
In a common application, groups of standard dual-speed 10/100 hubs, 10 Mb hubs, or 100 Mb hubs and switches would form a series of subnets
for workgroups or multi-system power users. A separate switched port on a Magnum 4K-Series Switch would serve each subnet, and each of
these subnets would have full 100 Mb or 10 Mb bandwidth, operating in either half- or full-duplex mode. Local traffic on one subnet, either 100
Mb or 10 Mb, is switch-isolated from the other subnets for high overall network performance.
