Chapter 1 Introduction

This section provides a functional description of the PRV-1059.

Functional Description

PRV-1059 is a rugged VLAN-capable 5-port PC/104 Fast Ethernet switch featuring very low power consum ption
and highly reliable extended-temperature operation up to +85°C (185°F). Supporting auto-MDI-MDIX network
installation, the board is designed for simple plug-and-play operation, enabling up to five embedded computing
devices to be networked together using 10BaseT or 100BaseTX Local Area Network (LAN) connections.

Field programmable, port-based VLAN functionality is supported on select models. This powerful feature
enables any combination of ports to be connected together in subnets for use in a small secure or non -secure
network. Fully IEEE 802.3 and IEEE 802.3u compliant, its five transceiver ports are flexibly designed so that any
port can serve as an uplink. The module can either be used as a standalone net work switch (no processor board
required) or in combination with embedded systems that support a PC/104 (ISA) bus.

The card integrates fully independent media access controllers (MACs), an embedded frame buffer memory,
and a high-speed address look-up engine, along with support for auto-crossover, auto-polarity, auto-negotiation,
and bridge loop prevention.

Qualified to MIL-STD-810 environmental standards, the compact PRV-1059 switch is ideally suited to space­constrained, high reliability aviation, industrial, military, and transportation applications where extreme
temperature and high shock/vibration exist. The unit is only 3.550” x 3.775” (90x96 mm) in size. All versions
include mounting holes to facilitate simple installation, as well as support for local or remote monitoring of LED
activity for data RX/TX and connectivity.

Ethernet connections are made through either onboard RJ-45 jacks or right-angle, locking Molex connectors.
The 4-pin Molex headers enable embedded systems to optionally mount RJ-45 jacks in a faceplate, endcap or
enclosure using a Parvus cable set (sold separately), which includes five female Molex to RJ-45
adapters. Power connections can be made through either the PC/104 (ISA) bus or externally through a 2-p in
Molex connector.

About PC/104

The PC/104 specification is characterized by its small form-factor (3.550" x 3.775"), stackable 104-pin/socket
ISA bus connector, and reduced bus signal drive, making PC/104's size, durability, expandability, reliability,
quality, and power consumption ideal for embedded computing. PC/104 technology leverages the same readily
available development tools used with personal desktop computers to dramatically improve time-to-market for
embedded systems development. The full PC/104 specification can be found at the PC/104 Consortium Web
site: http://www.pc104.org/technology/pc104_tech.html

Chapter 2 Quick Start-up

This section describes the installation of the PRV-1059.

Installation

The non-VLAN switch does not require drivers or software configuration. Users can immediately use any of the
features of the product simply by attaching the cables and supplying power to the unit through either the PC/104
bus or 2-pin power header, depending on the version purchased. The VLAN-enabled switch req uires use of the
Parvus cable (sold separately) and software to configure the VLAN settings. Configuration and connection of the
VLAN switch is described in chapter 5.

Carefully remove the board from its anti-static bag. For PC/104 applications, make sure power is turned off, then
carefully line up all pins before insertion. Attach the 10/100 Ethernet Switch into a PC/104 card stack by mating
PC/104 bus connector to PC/104 bus connector.

Installing Network Cables and Establishing Connectivity

The following types of cabling can be used with the 10/100 Ethernet Switch:
10BaseT Category 3,4 or 5 UTP/STP
100BaseTX Category 5 UTP/STP

Twisted-pair crossed cabling (10BaseT or 100BaseT) is recommended yet not required for the uplink connection
(switch-to-switch). Straight cabling for the remaining port connections (switch-to-PC) is similarly recommended,
but not required.

The board supports Auto MDI-/MDIX Crossover, which allows it to determine whether or not it needs to cross
over between receive/transmit pairs, virtually eliminating the need for an external crossover cable. If it
interoperates with a device that cannot automatically correct for crossover, the swit ch makes the necessary
adjustment prior to commencing auto-negotiation. Similarly, if the switch interoperates with a device that
implements MDI-MDIX crossover, a random algorithm determines which device performs the crossover.

The IEEE802.3ab specification, although well-written, does not clearly specify all linking conditions which may
occur between the various modes of operation of Ethernet, taking into account auto-crossover, auto-n egotiation,
and forced modes of operation (10/100 forced speeds using either full or half duplex). As a result, mixing auto­crossover with forced modes of operation may lead to initial link problems whenever a cable is first “live”
connected. Also, because of incompatibilities between various switch IC manufactures related to the IEEE

802.3ab specification, occasionally, link connectivity is not established immediately. When plugging in a new
cable, if a link is not established within about 10 seconds (usually much faster!), then the user should simply
cycle the power to the switch, turning it off and back on. In all cases, cycling power should result in a successful
link, even when auto-detecting through forced modes of operation (10-base T/half, 10-base T/full, 100–base
T/half and 100-base T/full). If it isn’t possible to cycle power, then cycling power of the associated link partner
may be an option. At worst, and in rare cases, if power cannot be cycled, then eventually (within several minutes
at the most) a link should successfully be established. Therefore, in these extreme rare cases, patience may be
needed. However, once link is established, the switch will not miss packets outside of normal collision events,
even when operating in harsh conditions using very long cables up to 100-meters in length.
