Stackable Capabilities

RESET Button

Resetting the hub with the front panel RESET button reboots the SEHI and initializes the processor.

Local Management

Manage the SEHI and 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 SEHI RJ45 COM port.

2.3STACKABLE CAPABILITIES

The SEHI intelligent hub is designed to manage the Cabletron Systems series of SEH non-intelligent hubs. The SEHI serves as the logical “top” of the stack. It manages all SEH hubs in the stack providing 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 Cabletron Systems external HubSTACK Interconnect cables. Stackable configurations make it possible to maintain only one IEEE repeater hop while providing up to 130 10BASE-T Ethernet ports. Add or remove hubs from the stack without powering down.

2.4REMOTE NETWORK MANAGEMENT CAPABILITIES

Manage the SEHI remotely with any SNMP network management system. Cabletron Systems offers the following remote management packages:

Cabletron Systems SPECTRUM

Cabletron Systems SPECTRUM Element Manager/Windows

Cabletron Systems Remote SPECTRUM Portable Management Applications

Third Party SNMP compliant Network Management Packages
