IBM 8260 manual Management and Controller Modules

1.3.2.2 8260 TR 18 Port Active Module Switching Module

The 8260 TR 18 Port Active Module Switching module is a single-slot module which provides attachment of up to 18 workstations to one of the 10 token-ring segments on the ShuntBus using both STP and UTP cables. This module provides active re-timing and regeneration of the signal on every port.

Ports 17 and 18 on this module can optionally be configured to act as fully repeated RI/RO trunk ports.

1.3.2.3 8260 TR Dual Fiber Repeater Module

The 8260 TR Dual Fiber Repeater module is a single-slot module providing 10 lobe ports with RJ-45 connectors and two RI/RO trunk ports with ST fiber connectors. Using the per-port switching feature, any of the lobes or any set of RI/RO trunk ports can be connected to any of the 10 token-ring segments on the ShuntBus.

Lobe ports support both UTP and STP cabling and each port provides active re-timing and regeneration of the signal.

The fiber RI/RO trunk ports are fully repeated and can be used for connecting your 8260 to other hubs over a distance of 2 km.

1.3.2.4 8260 TR 20 Port Passive Module-Switching Module

The 8260 TR 20 Port Passive Module-Switching module is a single-slot module which allows you to attach up to 20 workstations, which can be switched on a per module basis, to any of the 10 token ring networks on the backplane. This module allows you to use either UTP or STP cabling. Unlike the active module, it does not provide simultaneous support for both UTP and STP cabling.

1.3.2.5 8260 Jitter Attenuator Daughter Card

The 8260 Jitter Attenuator daughter card allows you to filter excessive amounts of jitter that may have accumulated in other equipment, before passing the signal to the 8260 backplane. The Jitter Attenuator daughter card can be mounted on any 8260 token-ring media module.

1.3.3 Management and Controller Modules

1.3.3.1 8260 Distributed Management Module (DMM)

The Distributed Management Module is an independent management module which allows you to fully manage and control the 8260 Multiprotocol Intelligent Hub and all the 8250/8260 modules. The DMM provides you with flexibility in handling the management of network segments with different protocols and media modules via a single management module using a single slot in the 8260 payload area. There are two different versions of DMM:

∙

∙

A Distributed Management Module with Ethernet Carrier - (DMM with Ethernet

Carrier) - The DMM with Ethernet Carrier module is a management module which is capable of housing up to 6 Ethernet MAC daughter cards.

AStand-alone Distributed Management Module (Stand-alone DMM ) - the stand-alone DDM module is a management module which is not capable of housing any Ethernet MAC daughter cards.
