2.2 Product Description
The Magnum P62F-Series Ethernet “Outdoor” Switches are designed to operate in
abnormal temperature applications, and are suitable for use in environments with inhospitable
high / low temperatures. Each Magnum P62F Ethernet switch provides two built-in 100Mb full-
duplex switched fiber ports so that several units can be daisy-chained, coupled with the
convenience of six switched 10/100Mb copper (RJ45) ports for easy connectivity to local nodes
and devices, all in one compact rugged unit.
The two “future-proof” fiber ports have been designed with full-duplex 100Mbps
switched fiber port, and six copper (RJ-45) with full / half-duplex-10/100-auto-negotiating ports.
The Magnum P62F-Series Ethernet Switches provide the switching speed and the reliability to
smoothly support multiple workgroups at 100Mbps or 10Mbps speed. The optional fiber ports
are normally configured and tested with the Magnum P62F unit in the factory, and available in
multi-mode and single-mode SC-type fiber connectors.
Designed specifically to operate in temperature uncontrolled applications, the P62F’s
high strength steel case functions as a heat sink to draw away the heat from the internal
electronics and dissipate it. The efficient design of P62F case can easily handle the unusual heat
of 70°
°°
°C (160°
°°
°F) and extreme cold of -40°
°°
°C (-40°
°°
°F). when properly installed (see Sec. 3.0).
Applications for Magnum P62F-Series Switches include roadside traffic data
collection and control stations, unheated and or high temperatures locations, plenums and ceiling
locations in commercial buildings, data communications huts and pedestals, and military sites.
A Magnum P62F Ethernet Switch is easy to install and use. Addresses of attached
nodes are automatically learned and maintained, adapting the switching services to network
changes and expansions. Top-mounted LEDs provide extra advantage to the user to observe
status information of each port. The Magnum P62F-Series Ethernet Switches generate high
performance plug-and-play operation in a rugged package. The high-strength steel enclosure
gives extra protection.
Each P62F Ethernet Switch is non-blocking on all ports and has 1MB packet buffers
and a 16K-node address table for advanced performance. A Magnum P62F Ethernet Switch,
armed with store-and-forward switching ability, filters all faulty packets to minimize traffic
congestion.

2.2.1 Magnum P62F-Series chassis with fiber SC (m.m. or single-mode) connectors
Magnum P62F-5V Magnum P62F
The Magnum P62F’s chassis houses one main PC board. The front side of the chassis
has a half dozen RJ-45 twisted-pair ports and two 100Mbps full-duplex fiber ports (one on
each side of the RJ-45 ports) as shown in the adjacent picture. The fiber ports operate in full-
duplex mode only to provide higher bandwidth and longer distances on fiber. All the LEDs
are mounted on the top cover to conveniently indicate operating status of all ports.
There is a power on (PWR) indicator, and a SELF TEST (self-test at power up in
progress or failed) for the unit. For each RJ-45 (ports # 2 -7), there are Link and Activity
(LK/ACT) LEDs indicating traffic, and 10/100 (ON for 100Mbps), and full/half (F/H)
duplex indicators. The fiber ports (#1 and 8), have (LK/ACT) indicators.
The rugged design of the case using high-strength rugged 18-gauge steel enables this
product to withstand environments with inhospitable high / low temperatures, and makes it
suitable for outdoors, road-side pedestals, control rooms and military use.
The DC power plug connector or “jack” is in the left front of the chassis. The Magnum
P62F Model is typically designed for power input of 24VDC or –48VDC only. The DC
input power supports a wide range, from 20-70 VDC auto-ranging. DC power input is
featured for high reliability and convenience in out-of-the-way locations.
The Magnum P62F-5V is available with an External Power Source (Optional) for
power input of universal AC power using the Magnum PSX-A unit. The 125VDC model
(PSX-T) input power supports a range of 100-275VDC and comes with input safety shield,
fuses, and is diode-protected against accidental reverse polarity connection.
The AC Power Source, PSX-A, is equipped with worldwide range of 85-264vac, 47-
63Hz , auto-ranging with 5VDC , 3Amps Power output. For both models , the military style

screw-lock plug provides a secure connection to the P62F-5V Ethernet Switch unit.
See Section 3.3 for detail description of the PSX-A and PSX-T external power sources.
2.3 Fiber port, SC Connectors The Fast
Ethernet fiber switched ports on the Magnum P62F operate at fixed 100Mb speed and full-
duplex mode for the best performance. The P62F’s fiber ports are factory-built as either a
multi-mode or single-mode SC connectors. A yellow label on the fiber port connector will
indicate if it is single-mode . . . otherwise it is a multi-mode port. The 100Mbps fiber ports
are each a switched port and perform as a domain, providing a high bandwidth backbone
connection and supporting long (up to 20km single-mode, or 40km special “long-reach”)
fiber cable distances for installation versatility.
On Magnum P62F units, there are three LED’s for
each of the RJ-45 switched ports. The F/H indicates full-
duplex when ON; when it is OFF, operation is half-duplex.
One (LK/ACT) is steady ON to indicate LINK, and blinking
indicates the port is transmitting / receiving. The 10/100 LED
is ON for 100Mbps and OFF for 10 Mbps (when LINK is
made). For fiber ports, the LEDs are the same except no F/H
(and 10Mb is not possible).
A device must be connected to the other end of a
port’s cable and a proper link (LK lit) must be made with the device at the other end of the cable
in order for each LINK LED to provide a valid indication of operating conditions.
2.4 Frame Buffering and Latency
The Magnum P62F is a store-and-forward switch. 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.
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

Magnum P62F-Series Ethernet Switches Installation and User Guide (11/01)
10
www GarrettCom com ..
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.
To minimize the possibility of dropping frames on congested ports, each Magnum
P62F Ethernet Switch dynamically allocates buffer space from an 1MB memory pool, ensuring
that heavily used ports receive very large buffer space for packet storage. (Many other switches
have their packet buffer storage space divided evenly across all ports, resulting in a small, fixed
number of packets to be stored per port. When the port buffer fills up, dropped packets result.)
This dynamic buffer allocation provides the capability for the maximum resources of the
Magnum P62F unit to be applied to all traffic loads, even when the traffic activity is unbalanced
across the ports. Since the traffic on an operating network is constantly varying in packet
density per port and in aggregate density, the Magnum P62F Ethernet Switches are constantly
adapting internally to provide maximum network performance with the least dropped packets.
When the P62F 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 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 P62F Ethernet Switch 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 RJ-45 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 P62F Ethernet Switch varies with the port-speed 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 10Mb. For 100Mb-to-100Mb forwarding, the latency is 5
microseconds plus the packet time at 100Mb.

2.6 Applications
The P62F is designed specifically for harsh temperature environments and brings
future-proof fiber and widely-used copper connectivity to out-of-the-way sites and outdoors.
Example 1. Magnum P62F In this example, a Magnum P62F Ethernet Switch serves
roadside real time traffic data collection and transmits it to a remote control station over fiber.
Since multiple traffic control sites are a long distance apart, they are all connected in series to
each other and to the central station. Some local users (using RJ-45 ports) may operate at
100Mbps, and some users and utility devices may run at 10 Mbps. A Magnum P62F Ethernet
Switch serves this requirement economically and efficiently. The six full- and half-duplex
switched ports make the required setup simple for collection of traffic data. The uncontrolled
outdoor temperature feature and high reliability of the P62F make it suited to the site.
The two 100Mbps full-duplex fiber ports easily fulfill the long distance connection
and provide high bandwidth for fast movement of data. The advance design of sealed P62F takes
care of it cooling method. The mechanical design of the Magnum P62F also enables it to be
easily placed in a NEMA 4 enclosure to provide an all- weather outdoor solution.

Example 2.
The Magnum P62F fits very well in high temperature locations (control
rooms)experiencing a need to scale its LAN quickly and cost effectively. With its half / full
duplex switching capability, the P62F provides a very economical high bandwidth solution at
each copper-cable user-access point. The 10/100 dual-speed functions to support a mixed
environment of 10 Mbps and 100Mbps users and devices, and the switching capability on all
ports provides bandwidth for high performance. The ruggedness of the P62F steel case and the
high reliability of the design (over 15 years of MTBF) complements the temperature controlled
packaging to provide an exceptional Ethernet product.

In this example,
the plenum-rated P62F takes
care of the LAN
connectivity requirement in
a harsh temperature
environment, mounted
above the ceiling in the
building. The non-
conductive fiber cabling inter-connects these switches through their fiber ports, providing a
protected Ethernet network facility as part of the building infrastructure. The steel enclosure and
20-70VDC power input qualifies the Magnum P62F to provide a dependable solution for any
temperature un-controlled location environments. The rugged enclosure with cable strain
feature gives extra protection and security to the LAN users.

3.0 INSTALLATION
This chapter provides instructions for installing Magnum P62F units.
3.1 Locating Magnum P62F 10/100Mb Ethernet Switch
The location of a Magnum P62F Ethernet Switch is dependent upon the physical
layout of the network. The rugged 18-gauge sheet steel which acts as a heat sink will normally
protect the P62F from accidental damage in any application setting. Install the unit so that the
metal case of the unit is in contact with a metal surface (such as a pedestal in the earth or an
equipment enclosure box) which does not exceed the ambient rating of the unit.
Designed primarily for the specific application, such as road traffic data collection and
control stations, high temperature locations, pedestals and military field sites, the Magnum P62F
supports DC power input for high reliability and convenience in out-of-the way locations. Locate
AC power (or any 20-70VDC three-wire (+, GND, -) power source for DC models) that is
within the range of the intended Magnum P62F unit. Maintain an open view of the top surface to
visually monitor the status LEDs.
3.1.1 Table-Top or Shelf Mounting
The Magnum P62F Ethernet switch can be easily mounted on a table-top, shelf or any
suitable metal surface, but should be securely mounted with appropriate screws. Rubber “feet”
(if any) that would insulate the case from metal-to-metal contact with the mounting surface
should be removed. The full temperature rating of the unit cannot be achieved if it is not
properly mounted on metal.
3.1.2 Wall (or vertical surface) mounting
The Magnum P62F switch is quite heavy because of its 18-gauge high-strength
steel case enclosure. Because of its weight, it is very important to select a sturdy place and
carefully attach it to metal surface. Attaching it to a metal surface is necessary to allow the
thermal heat transfer from the case, achieving rated ambient temperature specifications..
Each Magnum P62F Ethernet Switch is normally mounted with screws in a
vertical (cable connectors at the bottom) position. The base plate of the unit has screw holes
cut out, two top and two bottom. The spacing for the mounting screws is a rectangle 3.35” x
8.25” (8.25cm x 21cm) center-to-center. Four user-supplied screws attach the P62F base
plate to the vertical mounting surface.
