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  
TM  
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.
