CHAPTER 1: INTRODUCTION
1-4 SEH USER’S GUIDE
1.5 STACKABLE CAPABILITIES
The SEH is a non-intelligent hub designed to be managed by a Cabletron
Systems intelligent hub such as the SEHI or the MicroMMAC. 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. Stack up to five SEH hubs for a
non-managed stack or one intelligent hub and up to four SEH hubs for a
managed stack. Hubs can be added or removed from the stack without
powering down the entire stack.
