Stackable Capabilities

LANVIEW LEDs

Cabletron Systems LANVIEW status monitoring and diagnostics system is a troubleshooting tool that helps in diagnosing power failures, collisions, cable faults, and link problems. The LANVIEW LEDs are conveniently located on the SEHI front panel.

RESET Button

Resetting the hub with the front panel RESET Button reboots the SEHI and initializes the processor. Resetting the SEHI also resets all of the SEH non-intelligent hubs in the stack.

Local Management

Manage the SEHI and its attached segments through Local Management on the SEHI. Local Management provides full packet and error statistics for the entire stack, individual device, or individual port. Access Local Management by attaching a DEC VT320 terminal or a PC using VT320 emulation software to the RJ45 COM port on the SEHI. Cabletron Systems provides a UTP console cable with RJ45 connectors at each end, adapters for DB9 or DB25 connections and an instruction sheet with adapter pinout information with the SEHI. Chapter 7, Local Management, provides detailed information on setting up and managing your network through Local Management.

2.3STACKABLE CAPABILITIES

The SEHI100TX-22 intelligent hub is designed to manage a stack of up to four Cabletron Systems SEH100TX-22 non-intelligent hubs. The SEHI is placed at the bottom of the stack. It manages all SEH hubs in the stack and provides full packet and error statistics for the entire stack, individual device, or individual port.

Stack up to four SEH non-intelligent hubs with one SEHI using the Cabletron Systems external HubSTACK Interconnect cables provided with each SEH. Stackable configurations make it possible to maintain only one IEEE repeater hop while providing up to 120 ports. Hubs can be added or removed from the stack without having to power down the entire stack.
