CABLE SPECIFICATIONS
 
The SEH-22 and SEH-24 network ports support Shielded Twisted Pair 
(STP) and Unshielded Twisted Pair (UTP) cabling. 
Ethernet Port Interface Modules (EPIMs) expand a network using UTP, 
STP, Multimode Fiber Optic, Single Mode Fiber Optic, or Thin Coaxial 
cabling. For information concerning EPIMs, refer to Appendix A. 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 the 
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.
 
2.1.1 HubSTACK Interconnect Cable Requirements

Chapter 1 for cable part numbers. The cables attach to the SEH rear panel 
bus ports.
The rear panel of the SEH has an SEH Interconnect Bus Out Port (male
