Managing the Operational Link Map
The Link Map for a Managed Concentrator 210
A managed concentrator includes a processor module such as a Management Processor
210, and an I/O module such as a model 10BASE-T Concentrator 202. The processor
module has one Ethernet link which connects to the concentrator. The concentrator
connects to midplane Ethernet segment A by default. While concentrator I/O modules are
available as independent products, they must be managed from a processor module such as
a Management Processor 210.
Figure 3-1 shows the network map for a managed concentrator with a model 202 10BASE-T
Concentrator I/O module, which includes 24 ports, an AUI (LAN) link, and a FOIRL (fiber
optic) link.
