INSTALLATION
REQUIREMENTS/SPECIFICATIONS
This Chapter describes cabling requirements, network guidelines, and operating specifications for the SEHI. Be sure to read this chapter before you install the SEHI. 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 SEHI 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 port supports 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 stack the SEHI to modules in the stack with the SEHI HubSTACK Interconnect cable available only from Cabletron Systems. Refer to Chapter 1 for cable part numbers.The cable attaches to the SEHI’s rear panel bus port.
The rear panel of the SEHI has an Interconnect Bus Out port (male connector) to stack SEH
