Stackable Capabilities

LANVIEW LEDs

Cabletron Systems LANVIEW status monitoring and diagnostics system is a troubleshooting tool that helps in diagnosing power failures, collisions, cable faults, and link problems. The LANVIEW LEDs are conveniently located on the SEH front panel.

2.3STACKABLE CAPABILITIES

The SEH100TX-22 is a non-intelligent hub designed to be managed by the Cabletron Systems SEHI100TX-22 intelligent hub. The design of the SEH allows the stacking of five SEH hubs in an unmanaged configuration or up to four Cabletron Systems SEH non-intelligent hubs with one SEHI. The SEHI is placed at the bottom of the stack. It manages all SEH hubs in the stack and provides full packet and error statistics for the entire stack, individual devices, or individual ports.

SEH non-intelligent hubs may be stacked together or with one SEHI using Cabletron Systems HubSTACK Interconnect cables provided with the SEH. Stackable configurations make it possible to maintain only one IEEE repeater hop while providing up to 120 ports. The design allows hubs to be added or removed from a stack without having to power down the entire stack.

2.4RACK MOUNTING CAPABILITIES

The SEH can be installed in a 19-inch rack. Cabletron Systems provides the necessary brackets and mounting screws for the SEH. Refer to Chapter 4, Installation, for complete rack mounting instructions.
