Welcome to the Cabletron SystemsÕ SPECTRUM Element Manager for the CSX200 and CSX400 UserÕs Guide. We have designed this guide to serve as a simple reference for using SPECTRUM Element Manager for the CSX200 and CSX400.

SPECTRUM Element Manager provides management support for both the CyberSWITCH CSX200 and CyberSWITCH CSX400 stand-alone LAN-to-WAN access devices. Both the CSX200 series and the CSX400 device support PPP and Frame Relay WAN protocols, as well as multiprotocol bridging and IP/IPX routing.

The CSX200 series (CSX 201, 202, and 203) is designed for smaller branch ofÞces who need up to twelve Ethernet ports connected to a corporate WAN or ISP. Each CSX200 device has twelve RJ-45 ports and one WAN interface. Before shipping, the proper Wide Area Port Interface Module (WPIM) is installed in your device, depending on the technology you need. WPIM connections currently supported by SPEL include T1 and synchronous. In the future E1, DDS, DI (Drop-and- Insert), and HDSL will also be supported by SPECTRUM Element Manager. All of these WPIM options are discussed in Chapter 3, CSX200 and CSX400 WAN ConÞguration. The CSX200 also supports Point to Point Protocol (PPP), leased lines, and Frame Relay (RFC1490), providing up to four Permanent Virtual Connections (PVCs) to corporate ofÞces or the Internet.

The CSX400 is ideal for corporate ofÞces or larger branch sites that require two individual Ethernet LAN segments with single or dual WAN connectivity. The two Ethernet ports can be conÞgured with any available EPIM media, while the two WAN ports can be occupied by any swappable combination of Cabletron WPIMs. Currently SPECTRUM Element Manager can only manage a T1 or synchronous connection, but in the future WPIM options will also include DDS, DI, E1, and HDSL connectivity. Each WPIM can act independently, allowing

Cabletron Systems CSX200, CSX400 manual Introduction

CSX200, CSX400 specifications

Cabletron Systems was a leading developer of networking solutions, and its CSX400 and CSX200 series of high-performance switches represent some of the key innovations in the field of enterprise networking during their time. Both models were geared towards enhancing network reliability, efficiency, and speed, particularly in environments where heavy data traffic and complex networking demands were prevalent.

The CSX400, designed for larger enterprises, boasts a robust architecture capable of handling significant throughput. One of its standout features is its stackable design, allowing multiple switches to be interconnected and managed seamlessly as a single unit. This scalability provides organizations with the flexibility to expand their networks without significant infrastructure overhauls. The CSX400 supports various Ethernet standards, including 10/100 Ethernet and Gigabit Ethernet, positioning it to effectively manage both legacy and modern networking requirements.

In addition to its scalability, the CSX400 is distinguished by its advanced Layer 2 and Layer 3 routing capabilities. This dual-layer functionality enables efficient data handling and is instrumental in managing traffic between different network segments. Moreover, the switch incorporates features like VLAN (Virtual Local Area Network) support and Quality of Service (QoS) prioritization, allowing for enhanced performance of critical applications and streamlined bandwidth allocation.

On the other hand, the CSX200 series is tailored for smaller enterprises or branch offices needing a reliable yet efficient networking solution. Despite its compact design, the CSX200 is equipped with essential features that promote effective network management and security. It offers a simplified management interface, making it user-friendly for network administrators. The switch also provides essential access control measures, employing technologies like IEEE 802.1X for network access security.

Both the CSX400 and CSX200 prioritize performance through the incorporation of advanced switching technologies. They support features such as Spanning Tree Protocol (STP), enabling loop-free topologies and enhanced network resilience. These attributes are particularly crucial in dynamic networking environments where downtime can have significant repercussions on business operations.

Overall, Cabletron Systems' CSX400 and CSX200 series represent a blend of scalability, advanced routing capabilities, and user-friendly management, making them vital assets for organizations looking to optimize their network infrastructure during a period of rapid technological evolution. With their rich feature sets and unwavering performance, these switches helped pave the way for modern networking solutions that cater to diverse enterprise needs.
