Ethernet
Type
The type column describes what functions the device in question performs. There
are three basic types of devices covered by this table. Repeaters are standalone
Ethernet multiport repeaters. They count as a single repeater hop for purposes of
calculating maximum network size or propagation delay. Stackables are Ethernet
repeaters that may stand alone or be connected to other stackable devices of the
same type to form a single Ethernet stack, which acts as one repeater domain. The
stackable base is an intelligent stackable device that can be used as the first device
in a stack, and which will extend management capabilities to non-intelligent
devices in the stack.

Max Management
The Max Management column indicates the highest level of management
functionality that the standalone or stackable device provides. There are three
levels of management functionality, or lack thereof. Devices with a Max
Management of NONE have no management control and no management station
interface. Devices capable of Simple Network Management Protocol (SNMP)
management support Cabletron Systems SNMP implementation, which includes
the functions of SNMP Management Information Base II (MIB II) and the
Cabletron Proprietary MIB. RMON-capable devices include all SNMP functions
and several of the nine standardized Remote MONitoring (RMON) groups.

Media
The Media column of the table indicates the type of networking cable that is
supported by the device. The specifics of media support and connector type are
dependent upon the individual product. More detailed information regarding the
types and numbers of connectors on specific products can be found in the Product
Descriptions section of this document or in the Cabletron Systems Networking
Solutions Product Guide.

Port Count
The Port Count column indicates the number of fixed (non-BRIM or PIM) ports
that are available on the device.
that are available on the device.
PIMs/BRIMs
The PIMs/BRIMs column indicates the number and type of Interface Modules
that the device can support. These PIM and BRIM slots are ports available in
excess of the number given for the device’s port count. Thus, an MR9T-E supports
a total of nine ports: eight UTP ports and one EPIM port.

NOTE
Stack bases may not be used in any position in a stack except
the base. They do not have the HubStack Interconnect Cable
ports required to be stack members other than the base.
