RuggedCom RuggedWireless RS900W Specification Sheet

The RuggedWireless™ RS900W is an industrially hardened
Ethernet switch which integrates an IEEE 802.11b/g Wireless
Access Point, with a fully managed wired 8-Port Ethernet switch
providing six Fast Ethernet copper only ports and two optional
copper or fiber ports. With the installation of the RS900W
wireless access point, a network designer will achieve the
integration of wired and wireless networks. The RS900W can be
configured as an access, client, or bridge device

Designed to operate reliably in harsh industrial environments the
RS900W provides a high level of immunity to electromagnetic
interference and heavy electrical surges typical of environments
found in electric utility substations, factory floors or in curb side
traffic control cabinets. An operating temperature range of -40°C

to +85°C coupled with hazardous location certification, optional
conformal coating and a galvanized steel enclosure allows the
RS900W to be placed in almost any location.

The RS900W functions as a standalone IEEE 802.11b/g access
point for wireless clients providing wireless data rates of up to
54Mbps. All wireless communications are protected by the very
latest "robust security networks" features including strong
encryption protocols using WPA with TKIP and even
WPA2/802.11i with AES support. Static authentication support is
provided by WPA-PSK. For additional centralized control, the
RS900W also supports IEEE 802.1X/RADIUS for wireless user
traffic and distributing dynamic encryption keys.

The embedded Rugged Operating System (ROSTM) provides
advanced networking features such as Enhanced Rapid
Spanning Tree (eRSTPTM), VLAN, Quality of Service, and a full
array of intelligent functionality and advanced cyber security
features for high network availability and manageability.

The RS900W is backed by a five year warranty and
unsurpassed technical support.

Features

Cyber Security

Cyber security is an urgent issue in many industries where
advanced automation and communications networks play
a crucial role in mission critical applications and where high
reliability is of paramount importance. Key ROS™ features that
address security issues at the local area network level include:

.Passwords - Multi-level user passwords secures switch

against unauthorized configuration

.SSH / SSL - Extends capability of password protection

to add encryption of passwords and data as they cross
the network

.Enable / Disable Ports - Capability to disable ports so that

traffic can not pass

.802.1q VLAN - Provides the ability to logically segregate

traffic between predefined ports on switches

.MAC Based Port Security - The ability to secure ports on

a switch so only specific Devices / MAC addresses can
communicate via that port

.802.1x Port Based Network Access Control - The ability

to lock down ports on a switch so that only authorized
clients can communicate via this port

.Radius - Provides centralized password management
.SNMPv3 - encrypted authentication and access security

The ROS™ cyber security features are included to help
address the various industry specific security standards such
as NERC CIP, ISA S99, AGA 12, IEC 62443, ISO 17799:2005
and PCSRF SPP-ICS.

Enhanced Rapid Spanning Tree Protocol (eRSTP™)

RuggedCom eRSTP allows the creation of fault-tolerant ring
and mesh Ethernet networks that incorporate redundant links
that are 'pruned' to prevent loops. eRSTP yields worst-case
fault recovery1of 5ms times the 'bridge diameter' and allows
rings of up to 160 switches. For example, a ring of ten
switches will have fault recovery times under 50ms. eRSTP
implements both STP and RSTP to ensure interoperability
with commercial switches unlike other proprietary 'ring'
solutions.

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 then transmit on a first come first serve basis.
ROS™ supports 'Class of Service' in accordance 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.

VLAN (IEEE 802.1q)

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. GVRP support is also provided to
simplify the configuration of the switches on the VLAN.

Link Aggregation (802.3ad)

The link aggregation feature provides the ability to aggregate
several Ethernet ports into one logical link (port trunk) with
higher bandwidth. This provides an inexpensive way to set up
a high speed backbone to improve network bandwidth. This
feature is also known as "port trunking", "port bundling", "port
teaming", and "ethernet trunk".

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:

.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.

.Restores traffic streams immediately after an RSTP

topology change.

SNMP (Simple Network Management Protocol)

SNMP provides a standardized method for network
management stations the ability to interrogate devices from
different vendors. SNMP versions supported by ROS™ are
v1, v2c, and v3. SNMPv3 in particular provides security
features (such as authentication, privacy, and access control)
not present in earlier SNMP versions. ROS™ also supports
numerous standard MIBs (Management Information Base)
allowing for easy integration with any network management
system (NMS).
