LANVIEW LEDs
Cabletron Systems’ LANVIEW Status Monitoring and Diagnostics
System is a troubleshooting tool that helps you diagnose power
failures, collisions, cable faults, and link problems. The LANVIEW
LEDs are conveniently located on the SEHI’s front panel.
Reset Button
The front panel Reset Button lets you reboot the SEHI and initialize
the processor.
Local Management
The SEHI’s Local Management lets you manage the SEHI and all its
attached segments. It also provides full packet and error statistics for
the entire stack, individual device, or individual port. You access Local
Management by attaching a DEC VT™ 320 terminal or a PC using
VT320 emulation software to the SEHI’s RJ45 COM port.
1.5 STACKABLE CAPABILITIES
The SEHI intelligent hub is designed to manage Cabletron’s SEH
series of non-intelligent hubs. The SEHI serves as the logical “top” of
the stack. It manages all SEH hubs in the stack providing full packet
and error statistics for the entire stack, individual device, or
individual port.
You can stack together up to four SEH non-intelligent hubs with one
SEHI using Cabletron’s external HubSTACK Interconnect cables.
Stackable configurations let you maintain only one IEEE repeater hop
while providing up to 130 Ethernet ports. You can also add or remove
hubs from the stack without having to power down.
1.6 REMOTE NETWORK MANAGEMENT CAPABILITIES
You can manage the SEHI remotely by any SNMP network
management system. Cabletron Systems offers the following remote
management packages:
• Cabletron Systems SPECTRUM
