Magnum DS50 / DS60s Dual Speed Hubs Installation and User Guide (06/02)
2.2 Product Description
The Magnum DS60C Dual-speed Hub Plus is an easy to install, cost-effective Dualspeed hub. It has five 10/100Mb repeater shared ports along with a 10/100 Mbps switched port
that can be configured to provide “auto-negotiating” or “Full fixed” connectivity between a
100Mb segment and a 10Mb segment; or between two 100Mb segments at full duplex
capability. The Magnum DS60F belongs to the same DS60’s family except the sixth port is a
switched Fiber port at 100Mbps and can be set at Full-duplex or Half-duplex to support any
connectivity with Hubs or switches. The “future-proof” fiber port provides a secure
longer distance advantage and eliminates the need for a media converter,
The Magnum DS50 dual-speed hub has only the five 10/100 Mb repeater ports. Each
port can independently identify (via IEEE 802.3u auto sensing) and accept either 100Mbps or
10Mbps Ethernet signals, adapting to match the best speed of the connected device. Each unit
has its own internal power supply. The Magnum DS50 / DS60 Dual-speed Hub Plus has two
internal traffic domains . . . one for the 100 Mb domain and one for the 10Mbps domain. The
100Mbps users share the 100Mbps domain’s bandwidth and the 10 Mbps users share the
10Mbps domain’s bandwidth.

Fig. 2.2.1 Magnum DS50 / DS60 is functionally both a 10Mbps and 100Mbps in one
The Magnum DS60s, because of their dual-speed capability and switched ports, are
ideally suited for adding a Fast Ethernet workgroup to an existing 10Mb or 100Mb network. A
small 10/100Mb workgroup connects to the five “hub” ports while another workgroup or an
existing network segment . . . a separate collision domain of 10Mb or 100Mb units . . . connects
to port 6. For expansion of the five 10/100Mb ports, an additional 100Mbps or 10Mb hub can
be cascaded from port 1. Each domain can have its own local servers and other local traffic.
Thus, the DS60s can bridge-isolate one collision domain from the other, separating the local
traffic between each workgroup’s users and servers from the rest of the network. The Magnum
DS60s will filter and forward the packets to / from port 6 and the other ports, thereby giving
more bandwidth to each domain for maximum network performance.
The Magnum DS50 / DS60s are available with an internal AC Power supply with
auto-ranging power voltage (100 - 240 VAC). The 24VDC and -48VDC Power supply option
enables this product to be used in the industrial and telecom markets. The Magnum DS50 /

Magnum DS50 / DS60s Dual Speed Hubs Installation and User Guide (06/02)
DS60s are “plug and play” units enclosed in a lightweight, compact, rugged metal enclosure
suitable for office, lab and industrial sites. The DS50 / DS60s are available for horizontal or
vertical mounting (see Section 3.1).
2.2.1 Magnum DS60F Dual-speed Hubs Plus, with Fiber Switched Port
The Magnum DS60F chassis houses one main board equipped with five
hub ports and a switched fiber port. The switched fiber port is available with an SC connector
and options of multi-mode,
single-mode and long reach. It
has an internal power supply and
a small cooling fan in the bottom,
extending ambient operation to
55C. The port side of the chassis
consists of five shared 10/100Mb
RJ-45 ports and one 100Mb
switched SC fiber port. There is
an up-link (UPLINK) switch next
to Port 1, which allows this port
to be used for cascading to a hub
or switch. There is a manual switch “F-H” underneath the switched port #6 which provides
“Full-duplex” and “Half-duplex” capability to the switched port
The Magnum DS60F has power (PWR) and collision (COL) LED’s and 10 and
100 LEDs for the unit. It also has link (LINK) and receive (RX) activity LEDs for each of the
five shared ports and for Port 6. The port #6 has a Full-duplex (FDX) and a speed (100) LED
also. Rubber feet on the bottom provide a sturdy grip and clearance for the exhaust of the
cooling fan.
The internal power supply is an auto ranging AC power supply for input of 115-230
vac, 50/60 Hz. Optionally available are 24VDC and -48VDC for the industrial and telecom
markets. The recessed male IEC power connector is located at the right-rear. Two mounting
brackets for optional wall mounting are supplied with each unit. An optional “edge- stand” is
available (See “Spare Parts Price List”) and is used for floor-mounting on carpeted surfaces.

Magnum DS50 / DS60s Dual Speed Hubs Installation and User Guide (06/02)
2.2.2 Fiber port, SC Connector for Model DS60F
SC type (single-mode or multi-mode)
The Fast Ethernet fiber
switched port on the Magnum DS60F is
set to operate at fixed 100Mb speed for
guaranteed high performance. The
DS60F’s fiber port is factory-built and
available either as a multi-mode SC, or
a single-mode or long-reach SC connector. The 100Mb fiber port will run at 100Mbs speed at
all times with manually selected full- and half-duplex capability. The 100Mbps fiber port is a
switched port and performs as a separate traffic domain, providing a high bandwidth backbone
connection (no media converter is required !) and supporting long (up to 40km) fiber cable
distances for installation versatility.
Port 6 (the fiber port) has an “F - H” user-selectable manual switch. When set in the
“F” position, it forces full-duplex mode. When set in the “H” position, it forces half-duplex
mode, still at 100Mbps speed.
On Magnum DS60F units, there are three LED’s for the switched ports. One (LK) is
steady ON to indicate LINK is operational. The speed (100) LED is ON for 100Mbps and OFF
for 10Mbps (when LINK is made). The F/H indicates full-duplex when ON. When it is OFF,
operation is half-duplex.
A fiber cable must be connected to the 100Mb port and a proper link (LK light) must be made
with the device at the other end of the cable in order for these LEDs to provide valid indications
of operating conditions.
2.2.3 Magnum DS60C Dual-speed Hubs Plus with Copper port, Chassis
The Magnum DS60C chassis
houses one main board for the five hub ports
Magnum DS60
and for the switched port. It has an internal
power supply and a small cooling fan in the
bottom. The front side of chassis consists of
