Magnum 4K8 Switches Installation and User Guide (10/04)

2.2 Product Description - Magnum 4K8 Switches

Magnum 4K8 Switches boost the performance of Ethernet LANs, and have the
flexibility of both twisted-pair switched ports and a fiber port. The optional fiber port
considered as the additional 9
popular fiber connector. The 8 dual speed RJ-45 ports are 10/100 Mb and support auto­negotiating.

The Magnum 4K8 Switches provide the switching speed and the reliability to
smoothly support multiple workgroups at 100Mbps or 10 Mbps speed. The optional
“future-proof” fiber port is normally 100Mbps speed with factory default setting to
operate in full-duplex mode. Alternatively, for 10Mbps fiber, a multi-mode half-duplex
ST-type port option is available. The optional fiber port is normally configured and
tested with the Magnum 4K8 unit in the factory, but may be configured in the field

Designed for use in departments with multiple workgroups, in remote offices
and in network traffic centers or multi-system power users, the Magnum 4K8 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. Front­mounted LEDs provide status information on each port. The Magnum 4K8 Switches
provide high performance plug-and-play operation in convenient rack-mount packages.

th

port, may be configured from a variety of user selected

The Magnum 4K8 switches are non-blocking on all ports and include 1MB
packet buffers and 16K-node address table for advanced performance. The Magnum 4K8
Switches, with store-and-forward switching, filter all faulty packets to minimize traffic
congestion.

2.2.1 Magnum 4K8 Switch chassis

Magnum 4K8 Switches come in chassis size of an 8-port rack-mount.

The rack-mount units are typically used in larger network wiring centers.
The optional fiber port is user configurable and can be selected from the offered popular

fiber port connectors. The fiber-port modules are normally factory installed, but may be
changed or added in the field. (See Section 5).

The 4K8 19” rack-mountable Switches comes along with eight 10/100 RJ-45
ports and one optional 10 or 100Mbps fiber port module on the right, i.e., with a capacity
of 9 switched ports.

All port, LED’ connector and manual switches are located on the front panel
of Magnum 4K8 Switches. There are power(PWR) and error(Error) indicators for the
unit. There are Link and Activity(Link/Act) indicators for each 10Mbps and 100Mbps
domain, for visual indication of the operating status of each domain, and there are Soeed
and F/H Full and Half duplex Leds for each port. The manual switch with (=, x)supports
the port#1 for crossover port feature, whereas “F-H” manual switch for FPM port are
user selectable for full fixed and half duplex. The IEC standard AC power connector (and
a manual ON - OFF power switch) located at the rear. Fan-driven cooling air flows left

The Magnum 4K8R is like the 4K8F except that the front panel has the
LEDs, and all the connecting ports and power feeds are in the back. This is convenient
for rack-mounting 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.

Magnum 4K8 Switches Installation and User Guide (10/04)

The Magnum 4K8R is dual-speed 10/100Mbps switch and has a fiber
connector port options. The switching capability allow the Magnum 4K8R to support
multiple workgroup smoothly with its own switched 100Mbps or 10Mbps domain.

Normally the 4K8R is 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 4K8R
a good high-availability choice for Telcos, ISPs, broadcast equipment, medical,
brokerage firm, financial facilities and Industrial Environment.

2.2.3 Fiber-port modules, 100Mb fiber

A

Fig.2.2.3 Fiber-Port Modules, FPM-ST, FPM-SC, FPM-MTRJ

The fiber port module is optional for Magnum 4K8 Switch. In a fiber port
module, all of the fiber ports are of the fixed speed at 100Mbps or 10Mb, either multi­or single-mode, and different connector type. Multi-mode 100Mbps models are available
with ST, SC, and MTRJ connections. Single-mode 100Mbps models are available with
SC connectors.

The 100Mb fiber port modules on the Magnum 4K8 normally are set (factory
default) to operate in full-duplex mode for best fiber distance and performance. On the
Magnum 4K8, the user may select full- or half-duplex mode per-port with an internal
jumper setting (See Section 3.4) for the flexibility to adapt to any type of Fast Ethernet
devices.

On Magnum FPMs, there are two LED’s per fiber port. The Link (LK) LED
indicates “ready for operation” when lit), and an LED indicates Receiving Activity

LK lit) must be made with the device at the other end of the cable in order for the LK
LEDs to provide valid indications of operating conditions.

2.2.4 Fiber-port modules, 10 Mb fiber

The 10Mb model FPM10-MST fiber port module is the

same as the 100Mb FPM-MST, except for 10 Mb speed rather
than 100Mb speed. It supports distances according to the
10Base-FL standard, i.e., 2Km distance for multi-mode fiber.
(Single-mode for 10km distance may be available as a special
order).

2.2.5 10/100 Dual-speed Switched ports, RJ-45 (copper)

The Magnum 4K8 copper has 8 port dual speed 10/100Mb switched. RJ-45
ports. The 10/100Mb switched ports are independently N-way auto-negotiating (as a
default setting),

There are three LED’s for each port. The LK/Act (Link/Activity) steady ON
for Link with no traffic and blinking indicates port is receiving and transmitting. The
Speed LED indicates operation at 100Mb speed when ON and at 10 Mb speed when OFF
(when auto-negotiation is not disabled). The F/H LED is ON to indicate full-duplex
operation and OFF to indicate half-duplex mode. A twisted pair cable must be connected
into each RJ-45 10/100Mb port and a proper Link (LK lit) must be made with the device
at the other end of the cable in order for the LEDs to provide valid indications of
operating conditions.

The port#1 is equipped with a Media Dependent Interface-Crossover (MDI­X) push-button switch to simplify cascaded or up-link connections.
