Cabletron Systems SEH-34 User Manual

 

Page 2-1

 

This chapter describes network guidelines, power requirements, and 
operating specifications for the SEH. Be sure to read this chapter 
before you install the SEH. Your network must meet the requirements 
and conditions specified in this chapter to obtain satisfactory 
performance from this equipment. Failure to follow these guidelines 
could result in poor network performance.

 

The SEH network ports support both Shielded Twisted Pair (STP) or 
Unshielded Twisted Pair (UTP) cabling. The Ethernet Port Interface 
Modules (EPIMs) let you expand your network using UTP, STP, 
Multimode Fiber Optic, Single Mode Fiber Optic, or Thin Coaxial 
cabling. The rear panel Interconnect Bus Ports support Cabletron 
Systems’ HubSTACK Interconnect cables for stackable applications.

Take care in planning and preparing the cabling and connections for 
your network. The quality of the connections and the length of cables 
are critical factors in determining the reliability of your network. The 
following sections describe specifications for each media type.

 

You connect units in the stack with HubSTACK Interconnect cables. 
Refer to Chapter 1 for cable part numbers. The cables attach to the 
SEH’s rear panel bus ports.

The rear panel of the SEH has an SEH Interconnect Bus Out Port 
(male connector) and an SEH Interconnect Bus In Port (female 
connector). The bus supports five stackable devices.
