2.3 Magnum S14-Series, with four (RJ-45) Copper ports
The Magnum S14-Series chassis houses one main PC board. The power supply is
an external AC unit or internal DC via a screw terminal block. The front side of the chassis
has three twisted-pair switched ports and one port is provided on the rear side. All the four
ports of the S14-Series convenient switch support auto-cross (MDIX), and perform the
auto-cross in the auto-negotiation mode only.
Dual LEDs indicate operating status of ports may be viewed from any direction,
and are mounted on the top as well as end for convenience. There are power (PWR)
indicators for the unit to validate that the unit is turned ON. For each port, there are Link
and Activity (LK/ACT) LEDs indicating traffic and mounted on the top of the unit,
whereas the end LEDs mounted next to ports indicate (LK/Act) as LA1, LA2, LA3, LA4
for each of the four ports. 10/100 (ON for 100Mbps), and full/half duplex (F/H is ON for
full duplex) indicators for port # 2.
www GarrettCom com
..
16
S14 Convenient Switches Installation and User Guide (09/04)
The external DC power plug connector or “jack” is in the right rear of the chassis.
The internal DC input terminal block is also provided on the rear side of the unit.
Port #2 has the capability to configure that port as “FF” Full-Fixed for connecting
the 100Mb Full Duplex ports, or “A” to connect with an auto-negotiating port. Port #2 is
controlled by the manually-selectable slide-switch (FF-A), mounted underneath the port.
Use care in changing the switch position as the switch is small and fragile. See section 4.4.
2.4 Frame Buffering and Latency
The Magnum S14-Series Convenient Switches are store-and-forward switches.
Each frame (or packet) is loaded into the Switch’s memory and inspected before forwarding
can occur. This technique ensures that all forwarded frames are of a valid length and have
the correct CRC, i.e., are good packets. This eliminates the propagation of bad packets,
enabling all of the available bandwidth to be used for valid information.
www GarrettCom com
..
17
S14 Convenient Switches Installation and User Guide (09/04)
While other switching technologies such as "cut-through" or "express" impose
minimal frame latency, they will also permit bad frames to propagate out to the Ethernet
segments connected. The "cut-through" technique permits collision fragment frames,
which are a result of late collisions, to be forwarded to add to the network traffic. Since
there is no way to filter frames with a bad CRC (the entire frame must be present in order
for CRC to be calculated), the result of indiscriminate cut-through forwarding is greater
traffic congestion, especially at peak activity. Since collisions and bad packets are more
likely when traffic is heavy, the result of store-and-forward operation is that more
bandwidth is available for good packets when the traffic load is greatest.
When the Switch detects that its free buffer queue space is low, the Switch sends
industry standard (full-duplex only) PAUSE packets out to the devices sending packets to
cause “flow control”. This tells the sending devices to temporarily stop sending traffic,
which allows a traffic catch-up to occur without dropping packets. Then, normal packet
www GarrettCom com
..
18
S14 Convenient Switches Installation and User Guide (09/04)
buffering and processing resumes. This flow-control sequence occurs in a small fraction of
a second and is transparent to an observer. See Section 4.6 for additional details.
Another feature implemented in Magnum S14-Series Convenient Switches is a
collision-based flow-control mechanism (when operating at half-duplex only). When the
Switch detects that its free buffer queue space is low, the Switch prevents more frames
from entering by forcing a collision signal on all receiving half-duplex ports in order to stop
incoming traffic.
The latency (the time the frame spends in the Switch before it is sent along or
forwarded to its destination) of the S14-Series Convenient Switches varies with the portspeed types, and the length of the frame is a variable here as it is with all store-and-forward
switches. For 10 Mb-to-10 Mb or 10 Mb-to-100Mb or 100Mb-to-10 Mb forwarding, the
latency is 15 microseconds plus the packet time at 10 Mb. For 100Mb-to-100Mb
forwarding, the latency is 5 microseconds plus the packet time at 100Mb.

2.5 Features and Benefits
Small 4-port 10/100 Switch unit for edge-of-network applications
Where a small chunk of Ethernet connectivity is needed to connect edge
devices into the LAN, the Magnum S14-Series Switches provide 10/100
switching in a convenient and compact package that fits right into the site.
Three models for three application environments
- Yellow-label for the office and wiring closet
- Orange-label, Hardened for the factory floor.
- Red-label, premium rated for un-controlled temperatures, outdoors
Installation is “Plug and Play”, operation is transparent to software
The Magnum S14-Series Switches operate as a LAN switch, only
forwarding those packets from each domain that are needed on the other
domains. Internal address tables are self-learning. All ports are auto-cross.
Two sets of LEDs for viewing status from any angle.
Each S14-Series Convenient Switch is equipped with two sets (front and
side) of LEDs to provide status information when viewed at any angle or
mounting arrangement, rack-mount, DIN-Rail, or panel-mount.

Rugged metal case, Industrial grade
S14-Series are packaged in a rugged sheet metal enclosures to ensure
durability and noise immunity, even when placed in extended temperature
environments or high EMI noise sites; e.g industrial or outdoor applications.
AC and DC Power Supplies with extended temperature ratings
S14-Series power input may be a variety of types, external AC and internal
DC at 12V, 24V, or -48VDC. AC may be at extreme temperatures.
DC-input models can operate as dual-source
The 12V DC jack is present on DC-input models, so that the unit can operate
from an external AC PS, or from DC applied to the terminal block, either or
both present.
Dual-source power may increase availability, or be

converter (as shown in Figure above). The DC
terminal block on the Magnum S14H is located
on the left side of the unit and is equipped with
three (3) screw-down lead posts. The power

terminals are identified as positive (+) and negative (-), and they are floating inside the unit
so that either of the terminal may be grounded by the user if desired. The chassis is “earth”
or ground (GND).
The connection procedure is straightforward. Simply insert the DC leads to the
S14H’s power terminals, positive (+) and negative (-) screws. The use of Ground (GND)
optional; it connects to the S14H chassis. Ensure that each lead is securely tightened from
the top, as shown here.
NOTE: Always use a voltmeter to measure the voltage of the incoming power supply
and figure out the +ve potential lead or -ve potential lead. The more +ve potential lead
will connect to the post labeled “+ve” and the rest to the “-ve”.
The GND can be hooked up at the last.
When power is applied, the green PWR LED will illuminate.

3.8 Connecting Twisted Pair (RJ-45 ports)
The Magnum S14-Series Convenient Switches can be connected to only one
media type with two different speed i.e. 100BASE-TX and 10BASE-T. CAT 5 cables
should be used when making 100BASE-TX connections. When the ports are used as
10BASE-T ports, CAT 3 may be used. In either case, the maximum distance for
unshielded twisted pair cabling is 100 meters (328 ft).
Media
IEEE Standard Connector
Twisted Pair (CAT 3 or 5) 10BASE-T RJ-45
Twisted Pair (CAT 5) 100BASE-TX RJ-45
NOTE : It is recommended that high quality CAT. 5 cables (which work for both 10 Mbps
and 100Mbps) be used whenever possible in order to provide flexibility in a
mixed-speed network, since S14-series switch ports are auto-cross(MDIX) for
either 10 and 100Mbps. Note that the auto-cross function does not operate, if the
port is fixed or not supporting auto-negotiation.

3.8.1 Connecting Twisted Pair (RJ-45, CAT 3 or CAT 5, Unshielded or Shielded)
The following procedure describes how to connect a 10BASE-T or 100BASE-TX
twisted pair segment to the RJ-45 port. The procedure is the same for both unshielded and
shielded twisted pair cables.
1. Using standard twisted pair media, insert either end of the cable with a RJ-45 plug
into the RJ-45 connector of the port. Note that, even though the connector is shielded,
either unshielded or shielded cables and wiring may be used.
2. Connect the other end of the cable to the corresponding device.
3. Use the LINK LED to ensure proper connectivity by noting that the LED will be
illuminated when the unit is powered and proper connection is established. If this
does not help, ensure that the cable is connected properly and that the device on the
other end is powered and is not defective.
4. For Port # 1 or 1SW, if the LINK LED is not illuminated, move the switch which
has a cross-over or up-link for linking to another hub or Switch.

3.8.2 Connections to NICs which support Auto-Negotiation, RJ-45 ports
The copper ports of Magnum S14-Sereis Convenient Switches will function
properly with NICs (Network Interface Cards) which support Auto-Negotiation, and the
Fast Link Pulse (FLP) coding for the 100BASE-TX signaling system. When connecting a
NIC to the S14-Sereis, it may be necessary to reload the NIC drivers on the user device if
the NIC has been communicating with a protocol other than 100BASE-TX (such as
10BASE-T). When 100Mb operation is agreed and in use, the 10/100 LED is illuminated
steady ON and is OFF, if 10 Mbps traffic.
4.0 OPERATION
4.1 Dual-Speed Functionality, and Switching
The Magnum S14-Series Convenient Switches provide four switched
ports(three ports in the front and one on the rear). The architecture supports a dual speed
switching environment, with auto-negotiation capability.
www GarrettCom com
..
42
S14 Convenient Switches Installation and User Guide (09/04)
The switched RJ-45 ports are full-duplex and auto-sensing for speed. (See section
2.2). When the connected device is 10 Mbps, the S14s obeys all the rules of 10 Mbps
Ethernet configurations. The 10 Mbps users share a 10 Mbps traffic domain, and can
“communicate with” 100Mbps users as well as 100Mbps domain. Similarly, the 100Mbps
traffic obeys the rules of 100Mbps Ethernet, and can communicate with 10 Mb domain too.
Magnum S14-Series units are plug-and-play devices. There is no software
configuring to be done at installation or for maintenance. The internal functions of both are
described below.
Switching, Filtering and Forwarding
Each time a packet arrives on one of the switched ports, the decision is taken to
either filter or to forward the packet. Packets whose source and destination addresses on
the same port segment will be filtered, constraining them to one port and relieving the rest
www GarrettCom com
..
43
S14 Convenient Switches Installation and User Guide (09/04)
of the network from processing them. A packet whose destination address is on another
port segment will be forwarded to the appropriate port, and will not be sent to the other
ports where it is not needed. Packets needed for maintaining the operation of the network
(such as occasional multi-cast packets) are forwarded to all ports.
The Magnum S14-Series Convenient Switches operate in the store-and-forward
switching mode, which eliminates bad packets and enables peak performance to be
achieved when there is heavy traffic on the network.
Switching, Address Learning
The Magnum S14-Series units have address table capacity of 2K node addresses,
and are suitable for use in large networks. They are self-learning, so that as nodes are added
or removed or moved from one segment to another, the S14-Series automatically keeps up
with node locations.

..
44
S14 Convenient Switches Installation and User Guide (09/04)
An address-aging algorithm causes least-used addresses to fall out in favor of new
frequently-used addresses. To reset the address buffer, cycle power down-and-up.
4.2 Auto-cross (MDIX),Auto-negotiation and Speed-sensing
All the four RJ-45 ports independently support auto-cross (MDIX) in autonegotiation mode for speed in 10BASE-T and 100BASE-TX modes. The MDIX does the
auto-cross only under the Auto-negotiation mode, and will not take effect if the port is
fixed. Operation is according to the IEEE 802.3u standard.
When a RJ-45 cable connection is made, and each time a LINK is enabled, autonegotiation takes place. The P80F or P80C advertises its capability for 10 or 100 Mbps
speed, and the device at the other end of the cable should similarly advertise / respond and
both sides will agree to the speed being used. Depending upon the device connected, this
will result in agreement to operate at either 10 Mbps or 100Mbps speed.
