2.2 Product Description
The Magnum P62-Series Ethernet “Outdoor” Switches are designed to operate in
extended temperature applications and are suitable for use in environments with inhospitable high
/ low temperatures. Magnum P62-Series Hardened switches provide two built-in 100Mb full-
duplex switched fiber ports so that several units can be daisy-chained. These fiber ports are
coupled with the convenience of six switched 10/100Mb copper (RJ45) ports for easy
connectivity to local nodes and devices. All these features come in one compact rugged unit.
The Magnum P62-Series hardened Switches are available in a wide variety of options,
including our Managed (mP62..) version.The Managed mP62 can be easily deployed in an
existing and mixed vendor Ethernet network because of its features and capability. The Managed
(mP62) equipped with MNS-mP software supports managed edge-switch functions including
Menu-driven User Interface for ease of use, SNMP, QoS, Telnet, Password Security, Port Settings
Control, Spanning Tree Protocol, Port-based VLAN, BootP / DHCP etc..
The two built-in fiber ports are designed with full-duplex 100Mbps switched capability.
The six copper (RJ-45) ports come with full / half-duplex-10/100-auto-negotiating ability. The
Magnum P62-Series Hardened 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 Magnum P62 units in the factory and come available in
multi-mode and single-mode SC-type fiber connectors. For special fiber port types, request quote.
Designed specifically to operate in uncontrolled temperature applications, the hardened
Magnum P62’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 P62-Series high strength steel cases
can easily handle the extreme heat of 75°
°°
°C (170°
°°
°F) mP62 or 70°
°°
°C (160°
°°
°F) P62F and extreme
cold of -40°
°°
°C (-40°
°°
°F). when properly installed (see Sec. 3.0).
Applications for Magnum P62-Series Hardened Switches include roadside traffic data
collection and control stations, unheated and or high temperatures locations, above-ceiling
(plenum) spaces (see sect.3.3.1 for details) and ceiling mounts in commercial buildings, industrial
boiler rooms, mines and quarries, irrigation and pipeline facilities, on-board ships, cell towers,
data communication huts and pedestals, aeronautical installations and military sites.
A Magnum P62-Series hardened 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 for the user to observe the
status information of each port. The Magnum P62-Series Hardened Switches generate high

performance plug-and-play operation in a rugged package. The high-strength steel enclosure gives
extra protection.
Each P62-Series Hardened Switch is non-blocking on all ports and has large packet
buffers and a 4K-node address table for advanced performance. A Magnum P62-Series Switch,
with store-and-forward switching ability, filters all faulty packets to minimize traffic congestion.
2.2.1 Magnum P62-Series chassis w/fiber SC (m.m. or s.m) connectors
Magnum P62F-5V Magnum P62F
The Magnum P62-Series 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, 10/100 (ON for 100Mbps) LEDs indicating speed, and
full/half (F/H) duplex indicators. The fiber ports (#1 and 8), have (LK/ACT) indicators only.
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” temperatures, road-side pedestals, control rooms and military use.
For DC-powered models, the DC power plug connector or “jack” is in the left front of
the chassis. The DC Magnum P62-Series Model is typically used 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.

mP62-5V with the PSX-A = AC model
The Managed mP62 model is equipped with industry standard network management and
utility software operating features to make this Switch suitable to deploy in mission-critical
applications and in harsh environments. It also has internal components rated at 85`C so that
it can operate at higher (75`C) ambient temperatures than the P62F models.
The MNS-mP software supports managed edge-switch functions including menu-driven
user interface, SNMP, QoS, VLAN, STP, Port settings control, Password security, and
BootP / DHCP etc. The virtual LAN supports the Port based VLAN only and is easily setup
on the managed MP62 Switch to provide a secure and highly efficient network to its users.
The MENU driven MNS-mP CLI software is user friendly and easily operated by the
network user to configure the network as per their needs. The neat appearance of the MENU
driven MNS-mP is specially developed to have its function configured easily by the users.

The serial (Console) port is provided on the right front of the Managed mP62 Switch to
use the Console Management Interface(CMI) to manage all functions of the switch.
In addition, the Link-Loss-Learnfeature (patent pending) in mP62’s allows rapid
operating recovery from a link loss. The Link-Loss-Learn feature of the Magnum mP62
Ethernet Switch addresses issues that can occur when mP62’s are used in redundant network
configurations, such as when Spanning Tree Protocol (STP) is in use. With the Link-Loss-
Learn feature, Magnum mP62s are better able to handle some fault recovery situations, and
they may improve network reliability and provide faster fault recovery accordingly. Thus the
immediate re-learning of the addresses of the attached devices results in fast re-routing of
traffic in mP62s. See http://www.garrettcom.com/mp62.htm for additional information
and application information. Without a redundant network topology, the Link-Loss-Learn
feature is of no known benefit and should be turned off.
Developed using unique thermal techniques (patent pending), mP62’s operate smoothly
to a max of 75°C, which is 5°C more than the P62F product ratings of 70°C. Equipped with
high thermal dissipation features (patent pending), power supply flexibility, management
(MNS-mP software) capability, and a convection-cooled sealed case, the mP62s are ideal for
power utility plants, substations, roadside traffic control stations, unheated or high
temperature industrial plant locations, commercial building above-the-ceiling locations, data
communications huts and pedestals, and military field operation sites. When mounted in the
field, an mP62 is typically fastened vertically to a wall or pedestal, with cables connected at
the bottom to provide protection of the connectors from dirt and dust. The managed mP62
Switch’s package is IEC 529 rated IP51 and, while not waterproof, it can be placed in
NEMA 4 boxes, IP65 enclosures and similar waterproof enclosures to provide an all-weather
outdoor solution.
The AC/DC Power Supply options for the Managed mP62 Hardened Switches are the
same as for the other P62F models. For detailed descriptions of Power Supply options, see
Section 3.3.
2.2.3 Managed Network Software ( MNS-mP ) for Magnum mP62
Magnum mP62’s come with licensed MNS-mP software, which allows a user to
configure the Magnum mP62 as a Managed Hardened Switch and activate the Software features.

2.3 Fiber port, SC Connectors
The Fast Ethernet fiber switched ports on the Magnum P62-Series operate at
fixed 100Mb speed and full-duplex mode for the best performance. The P62’s fiber ports are
factory-built as either a multi-mode or single-mode SC connector. A yellow label on the fiber port
connector will indicate if it is single-mode. Otherwise it is a multi-mode port. Each 100Mbps
fiber port performs as a switched port and as a traffic domain, providing a high bandwidth
backbone connection that supports long (up to 20km single-mode, or 40km special “long-reach”)
fiber cable distances for installation versatility. A fiber port of a P62F is shown here,
On Magnum P62-Series units, there are three LED’s
for each of the RJ-45 switched ports. The F/H indicates full-
duplex when ON or half-duplex when OFF. The (LK/ACT)
LED is steady ON to indicate LINK, and blinking to indicate
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 there is no F/H LED because
10Mb is not possible.
There must be a device connected to the Magnum
P62-Series unit via a cable. A proper link (LK light) must be made between both devices at each
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 P62-Series Hardened Switch 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 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 P62-
Series Hardened 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
P62-Series 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 P62-Series Hardened Switches are constantly
adapting internally to provide maximum network performance with the least dropped packets.
When the P62-Series 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 P62-Series Hardened Ethernet 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 Hardened 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 Hardened Switch before it is sent along or
forwarded to its destination) of the P62-Series Hardened 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 P62-Series is designed specifically for harsh temperature environments and brings
future-proof fiber and widely-used copper connectivity to out-of-the-way sites.
Example 1. Magnum P62F In this example, a Magnum P62F Hardened Switch performs
roadside real time traffic data collection and transmits it to a remote control station over fiber.
Since multiple traffic control sites are long distances 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 P62-Series Hardened 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.
