3.1CABLE SPECIFICATIONS

The front panel SEHI100TX-22 network ports support Category 5 Unshielded Twisted Pair (UTP) cabling. Ethernet Port Interface Modules (EPIMs) expand the network using UTP (EPIM-100TX) or multimode ﬁber optic (EPIM-100FX or EPIM-100FMB) cabling. For information concerning the three EPIM types, refer to Appendix A. The rear panel Interconnect Bus ports support Cabletron Systems 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 describe speciﬁcations for each media type.

3.1.1HubSTACK Interconnect Cable Requirements

Attach the SEHI to the stacked SEH modules with the HubSTACK Interconnect cables provided with each SEH and available only from Cabletron Systems (P/N 9380209). The cable attaches to the SEHI rear panel bus “OUT” port. The SEHI must be placed at the bottom of the stack. Stack up to four SEH hubs together with one SEHI.
