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.
2.1CABLE 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.
2.1.1HubSTACK 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.
