LAN Network Manager provides graphical views of the IBM 8240 and 8244 Concentrators in your network and provides information and status about these concentrators. You can also display a generic graphical view that represents other types of FDDI concentrators, such as the IBM 8250 Concentrator or OEM FDDI concentrators.
This chapter contains the following topics:
LAN Network Manager supports both IBM and non-IBM FDDI concentrators. You manage the concentrators in your network by monitoring the status of the concentrators on the Segment submap and Concentrator submaps.
The FDDI concentrators in your network are represented by icons in the Segment submap. Double-clicking on the concentrator icon in a Segment submap opens a Concentrator submap.
The Concentrator submap displays a graphical representation of an FDDI concentrator. For 8240 and 8244 concentrators, the submap is a direct representation of the concentrator. For other FDDI concentrators, the submap is a generic representation of an FDDI concentrator.
As part of the graphical representation of the concentrator, the FDDI Concentrator submap also represents the other managed elements of the concentrator, including the ports and the station interface cartridges that are contained in the concentrator. These elements of the concentrator are represented by icons, which you can use to access those elements.
The top portion of the graphical representation of the concentrator includes an icon that represents the media access control (MAC) for the concentrator. Select the MAC icon to access profile, configuration, and performance information about the MAC element of the concentrator.
Similarly, select the icon at the top right of the concentrator to access profile, configuration, and fault information for the concentrator's station management (SMT) component.
The station interface cartridges are represented by the horizontal modules below the top portion of the concentrator. An icon to the right of each cartridge represents that cartridge. Select a cartridge icon to access profile information for the cartridge.
Within each cartridge icons represent the ports inserted in the cartridge. The port label indicates whether the port is being used as an A, B, M, or S port. Select a port to access profile, configuration, and fault information for the port.
The submap for the IBM 8244 concentrator is also a graphical representation of the concentrator, with a row of ports represented by icons. Other FDDI concentrators are displayed with a generic graphical view of a concentrator. The generic graphical view represents the managed elements of the concentrator with icons placed on a representation of a generic concentrator. To access management windows for these elements, select the icons in the submap in the same way you do in the 8240 and 8244 submaps.
At the lower right of all FDDI Concentrator submaps, just outside of the
concentrator, are icons that represent the concentrator's attachment,
path, and path class. Access profile, configuration, and fault
information for these components by selecting the icon and using the LAN
pull-down or context menu.

The Concentrator Profile window displays information about an FDDI concentrator. You can access identification information that describes the physical device, such as the serial number or the machine type. Information about the operation of the concentrator is also displayed and provides such details as the addressing scheme for the concentrator and the slots that are in use.
To display a concentrator profile, select the concentrator, then select Profile from either the LAN pull-down menu or the context menu.
To perform additional actions from the Concentrator Profile window, select
one of the following menu choices from the Actions: pull-down
menu.

To navigate directly to the SMT Profile window, select Profile from the Navigation pull-down menu on the Concentrator Profile window.
To save changes you make to the configuration parameters of an 8240 concentrator, use the Save configuration menu choice.
To cause a concentrator to reload its microcode and reset itself, select Soft reset Concentrator Profile Actions pull-down menu. When you select Soft reset, the concentrator removes itself from the communications path and reloads its microcode. Configuration changes that were saved are activated after the microcode is reloaded.
The Cartridge Profile window displays information about the cartridge, such as the current status, the physical connection type, and the number of ports that are attached.
To display information about a specific cartridge in the graphical submap, select the icon of the cartridge, then select Profile from either the LAN pull-down menu or the context menu.
