The network must meet the requirements and conditions speciﬁed in this chapter to obtain satisfactory performance from this equipment. Failure to follow these guidelines can result in poor network performance.

The network must meet the requirements and conditions speciﬁed in this chapter to obtain satisfactory performance from this equipment. Failure to follow these guidelines can result in poor network performance.

3.1CABLE SPECIFICATIONS

The SEHI-22FL network ports support 10BASE-FL Multimode Fiber Optic cabling.

Ethernet Port Interface Modules (EPIMs) expand a network using Unshielded Twisted Pair (UTP), Shielded Twisted Pair (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 port supports Cabletron Systems HubSTACK Interconnect cables for stackable applications.

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