INSTALLATION
REQUIREMENTS/SPECIFICATIONS
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.
2.1 CABLE SPECIFICATIONS
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.
2.1.1 HubSTACK Interconnect Cable Requirements
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.
