The RuggedServer™ RS401 is an industrially hardened, serial

device server with an integrated, fully managed Ethernet

switch, designed to operate reliably in electrically harsh and

climatically demanding environments. Based on the popular

RuggedServer™ RS400, the RS401 includes all the same

functionality including an integrated 4 port serial server,

4 port managed Ethernet switch, and optional v.90 modem.

In addition, the RS401 features a more compact design that is

particularly suited for panel mount locations or installations

with tight space restrictions. The RS401 is an ideal device to

connect and “IP-enable” legacy serial devices or IEDs for

Ethernet network connectivity.

RuggedServer™ RS401

4-Port Serial Device Server with Integrated 4-Port Managed Ethernet Switch

Ethernet Switch Management Features

Serial IP Encapsulation

with IEEE 802.1p that allows time critical traffic

to jump ahead to the front of the queue thus

minimizing latency and reducing jitter to allow such

demanding applications to operate correctly. ROS allows

priority classification by port, tags, MAC address, and IP

type of service (TOS). A configurable "weighted fair

queuing" algorithm controls how frames are emptied from

the queues.

Many 'legacy' devices (RTU, PLC, IED, etc.) only

support serial communications via RS232 or RS485.

ROS encapsulates the serial data within a TCP

connection allowing these devices to be reached via

an IP network. A wide range of baud rates, frame

packetization options, and diagnostics allows any serial

protocol to function. The RS401 has specific support for

the following serial protocols:

ꢀ. Raw Socket serial encapsulation

VLAN (IEEE 802.1q)

ꢀ. Modbus TCP (client and server)

Virtual local area networks (VLAN) allow the segregation

of a physical network into separate logical networks with

independent broadcast domains. A measure of security is

provided since hosts can only access other hosts on the

same VLAN and traffic storms are isolated. ROS supports

802.1q tagged Ethernet frames and VLAN trunks. Port

based classification allows legacy devices to be assigned

to the correct VLAN.

ꢀ. DNP 3

ꢀ. WIN and TIN

ꢀ. Microlok

MODBUS TCP

The Modbus protocol is ubiquitous in the industrial

control and automation world. ROS converts Modbus

RTU master/slave serial data packets to Modbus TCP

client/server packets for transmission over an IP network.

This allows communications to Modbus RTU slaves via

Ethernet and allows multiple masters to poll the same

slave device.

IGMP Snooping

ROS uses IGMP snooping (Internet Group Management

Protocol v1&v2) to intelligently forward or filter multicast

traffic streams (e.g. MPEG video) to or from hosts on the

network. This reduces the load on network trunks and

prevents packets from being received on hosts that are

not involved. ROS has a very powerful implementation

of IGMP snooping that:

Remote Dial-Up Access

A v.90 modem coupled with the PPP (Point to Point

Protocol) allows ROS to provide dial-up access via

POTS (plain old telephone system) providing connectivity

to serial devices and Ethernet LAN. PAP/CHAP

authentication provide security against

unauthorized access.

ꢀ Can be enabled on a per VLAN basis

ꢀ Detects and filters all multicast streams regardless of

whether subscribers exist

ꢀ Supports "router-less" operation by supporting an

"active" mode

Rapid Spanning Tree Protocol (IEEE 802.1w)

ꢀ Restores traffic streams immediately after an RSTP

topology change

RSTP allows the creation of fault-tolerant ring and mesh

Ethernet networks that incorporate redundant links that

are 'pruned' to prevent loops. The ROS optimized version

of RSTP yields worst-case failovers of 5ms times the

'bridge diameter' and allows rings of up to 80 switches.

For example, a ring of ten switches will have failover

times under 50ms. ROS implements both STP and RSTP

to ensure interoperability with commercial switches

unlike other proprietary 'ring' based solutions.

Ethernet Port Mirroring

ROS can be configured to duplicate all traffic on one

port to a designated mirror port. When combined with

a network analyzer, this can be a powerful

troubleshooting tool.

Ethernet Port Configuration and Status

ROS allows individual ports to be 'hard' configured for

speed, duplex, auto-negotiation, flow control and more.

This allows proper connection with devices that do

not negotiate or have unusual settings. Detailed status

of ports with alarm and SNMP trap on link problems

aid greatly in system troubleshooting.

Quality of Service (IEEE 802.1p)

Some networking applications such as real-time control

or VoIP (voice over IP) require predictable arrival times for

Ethernet frames. Switches can introduce latency in times

of heavy network traffic due to the internal queues that

buffer frames and than transmit on a first come first serve

basis. ROS supports 'Class of Service' in accordance

RuggedServer™ RS401

4-Port Serial Device Server with Integrated 4-Port Managed Ethernet Switch

Ethernet Switch Management Features

Ethernet Statistics and RMON

SNTP (Simple Network Time Protocol)

ROS provides continuously updating statistics per port

that provide both ingress and egress packet and byte

counters as well as detailed error figures. Also provided

is full support for the RMON statistics, history, alarms,

and event groups. RMON allows for very sophisticated

data collection, analysis and detection of traffic patterns.

SNTP automatically synchronizes the internal

clock of all ROS devices on the network. This allows for

correlation of time stamped events for troubleshooting.

Event Logging and Alarms

ROS records all significant events to a non-volatile

system log allowing forensic troubleshooting. Events

include link failure and recovery, unauthorized access,

broadcast storm detection, and self-test diagnostics

among others. Alarms provide a snapshot of recent

events that have yet to be acknowledged by the network

administrator. An extreme hardware relay is de-energized

during the presence of critical alarms allowing an

external controller to react if desired.

Loss of Link Management

Some intelligent electronic devices (IEDs) have dual fiber

optic ports with automatic failover to a backup port should

the primary fail. ROS ensures this mechanism works

reliably under all failure modes by appropriately disabling

link signals when required. ROS also flushes learned

MAC addresses to ensure the failover occurs quickly.

Ethernet Port Security

Configuration via ASCII Text File

ROS provides the ability to filter or accept traffic from

specific hosts to prevent unknown users or devices from

gaining access to the network. Unauthorized access

results in the port being shutdown for a period of time

along with SNMP trap and alarm generation.

All configuration parameters are stored in an ASCII

formatted text file that can easily be transferred via TFTP

or Xmodem. The configuration file can be saved for

backup purposes and easily manipulated by a text editor.

The text same file can be downloaded to the switch at

a later date in order to re-configure or restore a

previous configuration.

Broadcast Storm Filtering

Broadcast storms wreak havoc on a network and can

cause attached devices to malfunction. This could be

disastrous on a network with mission critical equipment.

ROS limits this by filtering broadcast frames with a

user-defined threshold.

Command Line Interface (CLI)

A command line interface can be used in conjunction

with remote shell to automate data retrieval, configuration

updates, and firmware upgrades. A powerful SQL-like

capability allows expert users the ability to selectively

retrieve or manipulate any parameters the device

has to offer.

SNMP (Simple Network Management Protocol)

SNMP provides a standardized method for network

management stations the ability to interrogate devices

from different vendors. ROS supports numerous standard

MIBs (Management Information Base) allowing for easy

integration with any network management system (NMS).

A feature of SNMP supported by ROS is the ability to

generate "traps" upon system events. A NMS can record

traps from multiple devices providing a powerful network

troubleshooting tool. RuggedVue is RuggedCom’s NMS

that provides graphical visualization of the network and

is fully integrated with all RuggedCom products.

HTML Web Browser and Telnet User Interfaces

ROS provides a simple, intuitive user interface for

configuration and monitoring via a standard graphical

web browser or via Telnet. All system parameters include

detailed on-line help to make setup a breeze. ROS,

presents a common look and feel and standardized

configuration process allowing easy migration to other

RuggedCom managed products.
