Product Description - ProSwitch Quad-Series Fiber Switches
ProSwitch Quad-Series Fiber Switches boost the performance of large Ethernet LANs, and have
the flexibility of both fiber and twisted-pair switched ports. Their "mixed-media" capability provides for a
variety of configurations including various types of fiber port connectors and modes, as well as allowing a
mix of 10/100Mbps RJ45 (copper) ports in the same unit. This flexibility is achieved via a family of quad-
port modules that can be integrated with a base unit, either in the factory or in the field, to adapt the unit
to the individual application's changing mixed-media requirements for a 10/100 switch product.
The ProSwitch Quad-Series provide the switching speed and the reliability to smoothly support
multiple workgroups at 100Mbps or 10Mbps. The Quad-Series offers the flexibility of 4, 8, 12 or 16-
switched 100Mbps or 10Mbps fiber and/or 10/100 twisted pair ports, in all the popular connector types.
The ProSwitch Quad-Series offers the QS580, QS5108 and QS5116 models, each with a configuration of
four port modules (Quad-port Modules) for fiber types and for copper, as well as "3+1" combo (3@copper
and 1@fiber) port modules. The Quad-port Modules can be configured into a Quad-Series Switch base
unit in any mix of port connector or media types.
Designed for use in departments with multiple workgroups, in remote offices and in network traffic
centers, the ProSwitch Quad-Series 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. Front-mounted LEDs provide status information on each port. The ProSwitch Quad-Series
switches provide high performance plug-and-play operation in convenient tabletop and rack-mount
packages.
2.2.1
ProSwitch Quad-Series chassis models
ProSwitch Quad-Series switches come in three chassis sizes, an 8-port tabletop, an 8-port rack-
mount, and a 16-port rack-mount. Each is configurable with a selection of quad-port (i.e., 4-port) modules,
providing the capability of 4, 8, 12, and 16-switched ports. The quad-port modules are normally factory
installed, but may be changed or added in the field.
The 8-port QS580 tabletop chassis is compact in size and suitable for shelf-mounted use in
network wiring centers. The QS5108 and QS5116 are 19" rack-mountable Switches with two or four
quad-port slots in the front, i.e., with a capacity of 8 or 16 switched ports. The QS5108 and QS5116 rack-
mount units are typically used in larger network wiring centers.
Mixed-media combination modules (4-port modules with three fiber ports and one twisted-pair
port) are supported in all of the Quad-Series Fiber Switch models. All quad-module manual-selection
switches and LED's are located on the front panel, with the IEC standard AC power connector (and a
manual ON - OFF power switch) located at the rear. Fan-driven cooling air flows left to right.

MTRJ-Small Form Factor
VF45-Small Form Factor
In a fiber quad-port module, all of the fiber ports are of the same speed, the same multi- or
singlemode, and the same connector type. Multimode 100Mbps models are available with ST, SC,
MTRJ, and VF45 connectors. Singlemode 100Mbps models are available with SC connectors.
The 100Mbps fiber quad-port modules on the ProSwitch Q-Series normally are set (factory
default) to operate in full-duplex mode for best fiber distance and performance. On the ProSwitch Q-
Series, 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 ProSwitch fiber QPMs, there are three LED's per fiber port. The Link (LK) LED indicates
"ready for operation" when lit, another LED indicates operation in full-duplex mode when ON (when it is
OFF, operation is half-duplex), and an LED indicates Receiving Activity (ACT) on the port. A fiber cable
must be connected to each 100Mbps port and a proper link (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.
2.2.3 Quad-port modules, 10Mbps fiber
The 10Mbps model QPM10-MST fiber quad-port module is the same as the 100Mbps QPM-MST,
except for 10Mbps speed rather than 100Mbps speed. It supports distances according to the 10Base-FL
standard, i.e., 2Km distance for multimode fiber. (Singlemode for 10km distance may be available as a
special order).
2.2.4
Quad-Port Module, RJ45 (copper)
The ProSwitch Q-Series copper port module, model QPM-
RJ45, provides four 10/100Mbps switched RJ45 ports. The
10/100Mbps switched ports are independently N-way auto-
negotiating for operation at 10 or 100Mbps speed in full- or half-
duplex mode (as a default setting). They independently move to
half-duplex mode at 10Mbps or at 100Mbps speed if the device at
the other end of the twisted pair cable is half-duplex or is not an
auto-negotiating device.
On the model QPM-RJ45, there are four LED's for each port. The LK (Link) indicates "ready for
operation" when lit. The ACT (Activity) indicates receiving activity on that port when lit. The 10/100 LED
indicates operation at 100Mbps speed when ON and at 10Mbps speed when OFF (when auto-negotiation
is not disabled). The FDX/HDX LED is ON to indicate full-duplex operation and OFF to indicate half-
duplex mode. A twisted pair cable must be connected into each RJ45 10/100Mbps 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.
Internal jumper settings (See Section 3.4) allow technicians to over-ride the auto-negotiation
feature and to manually set each port at full-duplex or half-duplex. One port on each RJ45 quad-port
