SPECTRUM and the SEHI
The SEHI is an intelligent stackable ethernet hub designed to provide
advanced management capabilities for up to five non-intelligent stackable
ethernet hubs. It is fully IEEE 802.3 compliant, and provides complete port
error breakdown, port to address matching, and monitoring of network traffic.
It contains twelve or twenty-four RJ45 or RJ71 station ports. One or two
modular EPIMs provide additional ports supporting ethernet coax, fiber optic,
STP, or UDP cabling.
SEH-32, SEH-34 Non-intelligent, 13 (1 RJ71, 1 EPIM) and 26 (2 RJ71s, 2
EPIMs) ports
SEH-22, SEH-24 Non-intelligent, 13 (12 RJ45s, 1 EPIM) and 26 (24 RJ45s, 2
EPIMs) ports

Device Model Description
NOTE
If you are running a previous version of SPECTRUM, the following user
interface aspects may differ from those in SPECTRUM version 4.0:
•Order and names of menu selections
• Navigational features (mouse button functionality)
NOTE
If you need to create a SEHI model manually, you must start within a
LAN_802.3 model. The SEHI cannot be manually modeled at the Universe
topology level.
