Compatibility with the 8250 family

1.1 Introduction

The 8260 is an intelligent managed hub which provides the platform to build local area networks using various types of cabling systems (such as STP, UTP, fiber and coax) and different types of LAN protocols (such as token-ring, Ethernet, and FDDI). Additionally, the 8260 provides platform for the implementation of

high-speed networks based on Asynchronous Transfer Mode (ATM) technology.

The 8260 is a rack-mountable hub and depending on the model it allows you to install up to 17 payload modules. These modules can be a combination of media and management modules providing you with the flexibility to design networks addressing the individual needs of your organization.

Media and management modules can be installed or removed from the 8260, while the hub is operational. This allows you to modify the configuration of the network with minimal disruption to the users.

The 8260 provides the room to install up to two controller modules. The second controller module will be used to provide backup for the primary controller module.

In addition to a wide range of 8260 media and management modules which are specifically designed to take advantage of the features offered by the new chassis, the 8260 supports all of the media and management modules from the 8250 (but not its controller module). This provides you with the ability to protect your investment in the 8250 modules.

Note: As the 8260 is taller than the 8250, an optional adapter kit is required to install the 8250 modules in an 8260.

The 8260 is designed to be a stand-alone unit or to be mounted in a standard 19rack. The 8260 is shipped with a rack mounting kit, a rubber feet kit and a cable tray assembly.

When you order the 8260, the following components will be included in the 8260 chassis which is shipped to you:
