Cabletron Systems SEHI100TX- User Manual

 

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.

 

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.

 

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, 
adaptors for DB9 or DB25 connections and an instruction sheet with 
adaptor pinout information with the SEHI. Chapter 7, 

 

, provides detailed information on setting up and managing 

your network through Local Management.

 

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.
