INTRODUCTION

LANVIEW LEDs

Cabletron Systems’ LANVIEW Status Monitoring and Diagnostics System is a troubleshooting tool that helps you diagnose power failures, collisions, cable faults, and link problems. The LANVIEW LEDs are conveniently located on the front panel.

1.5STACKABLE CAPABILITIES

The SEH is a non-intelligent hub designed to be managed by either the Cabletron Systems SEHI intelligent hub or the Cabletron Systems MicroMMAC intelligent hub. Intelligent hubs serve as the logical “top” of the stack. They manage all SEH hubs in the stack providing full packet and error statistics for the entire stack, individual device, or individual port. You can stack together up to five SEHs for a non-managed stack or one intelligent hub and up to four SEHs for a managed stack. You can also add or remove hubs from the stack without having to power down.

1.6OPTIONAL FEATURES

The following features are not included with the SEH but can be purchased separately from Cabletron Systems.

Ethernet Port Interface Modules (EPIMs)

EPIMs let you expand your network through a variety of media. Cabletron offers the EPIMs shown in Table 1-1.
