Issue 2 Installation and Operation Manual
Chapter 1: Introduction &
Specifications
Product Overview
The SpectraComm Ethernet Switch (SC-ES) provides
fast ethernet connectivity within the carrier’s internal
network, allowing efficient and secure management of
LAN-attached equipment. As part of the GDC
SpectraComm family of products, SC-ES offers the high
reliability and NEBS safety required in carrier
environments. SC-ES can be deployed as a replacement
to legacy hubs or in new installations where fast ethernet
switching is desired.
SC-ES cost-effectively increases network performance
by reducing the collision domain, thereby easing
congestion problems on existing shared-hub network
traffic. In addition, SC-ES eliminates unnecessary
network traffic and delivers dedicated bandwidth for
eachport.SC-ES alsoprovidesethernetsecurityfeatures
that enhance the security of the network.
This manual describes the SpectraComm Ethernet
Switches: the SC-ES 9-Port card and the SC-ES 18-Port
card. Both cards operate in the same manner, except
where noted.
SC-ES 9-Port Ethernet Switch
The SC-ES 9-Port is a single-width, 7-inch by 9.5-inch
(178 mm by 241 mm) printed circuit card that provides
eight RJ45 ports at the Front Panel and one RJ45 port at
the shelf rear panel. The SpectraComm 2000 shelf can
hold up to two SC-ES 9-Port cards, the SC 1001
Enclosure holds a single card. For higher density
applications, the SpectraComm 5000 shelf can hold up
to 16 cards; multiple shelves increment port density.
SC-ES 18-Port Ethernet Switch

Introduction & Specifications Product Overview

Installation and Operation Manual Issue 2
Theory of Operation
Ethernet Switching
Ethernet switching establishes a direct line of communication between two ports and maintains
multiple simultaneous links between various ports. This is a very efficient means of managing
networktraffic, in that informationissentdirectly from the portof origin to onlyitsdestinationport.
Media sharing is reduced since traffic is constrained to the segment for which it is destined, be it a
server, power user or workgroup.
This technology enables some key benefits over traditional Ethernet bridged and routed networks:
• Bridges and routers typically have many devices attached to their ports, sharing the available
bandwidth. An ethernet switch can change shared media to dedicated bandwidth; for example,
you can connect either a shared segment (a workgroup) or a dedicated segment (a power user
or server) to its ports.
• An ethernet switch installation is less complex than a bridge/router configuration. Moves, adds
and changes can be made with ease.
• Ethernetswitches enhances network efficiency, performance and flexibility without modifying
any software or hardware already running on the workstations.
Connectivity
LAN equipment at any site can be connected to the SC-ES’s 10/100Base-T LAN ports, providing
the functionality that is usually associated only with high-end fully managed switches.
• In theSC-ES 9-Port card, thereare eightFront Panel ports(1 -8) with Port 9 locatedat the upper
rear RJ45 connector. The device can operate as a stand-alone switch, or can employ Port 9 as a
logical uplink to another switch/hub device to accommodate higher port density requirements.
• In the SC-ES 18-Port card, there are sixteen Front Panel (1 - 8 and 10 - 17) with two additional
ports (9 and 18) located at the upper and lower rear RJ45 connector, respectively. Ports 9 and
18 can be used as logical uplinks to another switch/hub device in order to accommodate higher
port density requirements.
SC-ES Management
SC-ES device cards can be monitored and managed using standard protocols: locally via the Craft
interface, via password-protected Telnet, or via web-based command line interface (CLI)
commands from the central site or other remote sites. The SC-ES also maintains operational
statistics on the switch and traffic statistics for each of the ports.
SC-ES Security
SC-ES devices are multi-level password-protected and also provide inactivity timers. For periods
of heightened security alert, authorized users can disable individually the HTTP, SNMP and/or
TFTP access to the unit, preventing hacks. Each port on the SC-ES can also be configured for one
of several security modes designed to block ethernet access whenever an illegal MAC address or
cable connect/disconnect is detected.

using popular browsers. To enhance security, SC-ES supports web timeouts and password-
protected or disabled access over the web interface (HTTP).
SNMP Management (Future Release)
A future release of the SC-ES will support direct SNMP management; an embedded SNMP agent
allows read/write access to SC-ES using any standard SNMP controller. SNMP access can be
disabled to avoid hacks during intervals of heightened security.
Note SNMP support will not require a SpectraComm Manager (SCM) card co-located in the shelf.
TEAM Management
In TEAM applications, SC-ES will be recognized by TEAM (Total Enterprise Access
Management) software applications which use HPOV APIs (Application Programmer Interfaces)
to integrate with HP OpenView Windows and other network management applications.
This release of the SC-ES supports TEAM Auto-Discovery and polling only. Support for additional
TEAM features is planned in a future release of the SC-ES, such as a direct web and Telnet launch
from the map window. For more information on the availability and operation of these additional
features, refer to later issues of this document or contact your GDC Sales Representative.
Note TEAM support requires an SCM card co-located in the shelf with the SC-ES. For more information, refer to

Issue 2 Installation and Operation Manual
SC-ES Applications
The primary application of the SCES is to provide low-cost, NEBS compliant fast Ethernet
switching connectivity to the Carrier's internal LAN network. With NEBS, the SCES can be located
anywhere within a Carrier's network. For instance, SC-ES can be located in the Central Office
environment as part of the inside plant, or can be located in a remote office or CEV/Hut
environment as part of the outside plant equipment.
The SCES allows the segmenting of attached LAN devices to improve network performance and
provides a 200Mbps channel for servers. It allows a network to be mixed (10 and 100Mbps) for
optimal price/performance ratio, and is ideal for relieving bandwidth bottlenecks and providing
fasterresponse times. Using ethernet switch technology, SC-ES supports cabling distances of up to
100 meters by eliminating the propagation delays normally found with hubs/repeaters.
Simple Network Application
Figure 1-2 shows how the SCES may be deployed to extend the Carrier's management network to
a remote site. In this application, the SC-ES is installed at the remote site with one of the Ethernet
ports connected to the router or bridge at that site. The remaining SC-ES ports may be used to
connect to the LAN devices to be managed at that site.
For the example network shown below, a SC-IP card can provide the router/bridge functions at the
central and remote sites.

Installation and Operation Manual Issue 2
Large Network Applications
Figure 1-3 shows how theSCES may be used in a larger network. A Carrier can manage equipment
using a SCES at one Central Office location which has multiple remote sites (CEVs). Similarly,
multiple COs can also deploy the SCES. Such large-network deployment of the SC-ES provides
LAN connectivity from the Central site (NOC) all the way out to multiple remote sites.
The example network shown below, a future SpectraComm product, the SCEX-T3 card, can
provide the broadband router/bridge functions at the central site and central office.
Note As shown in Figure 1-3, SC-ES ports may be used to cascade switches together; likewise, SC-IP ports can be
used to cascade routers together.

Note For clarity, one SC-ES card and two SC-IP cards are shown in Figure 1-3’s Central Office shelf. In high
density applications, more SC-ES and SC-IP cards can be installed in a shelf to connect with remote sites
through additional T1 lines.
