Feature Summaries
The following summaries describe ELH100-12/24TX features in areas
such as standards compliance, functionality, performance, and options.
Dual-Speed Architecture
The ELH100-12/24TX hub provides both 10 and 100 Mbps repeater
buses. The speed of the device connected to each port is automatically
detected by the hub, and the port attached to the appropriate bus. Up to
6 hubs can be stacked together to form a dual-speed network. An optional
switch/media module can be added to any hub in the stack to bridge traffic
between the 10 Mbps and 100 Mbps repeater buses as required.
Software Download
The ELH100-12/24TX hubs support the industry-standard Trivial File
Transfer Protocol (TFTP) for downloading agent software. All hub
software is stored in a 2 MB flash ROM. The download feature allows you
to easily install software upgrades to the Agent Module. Software can
alternatively be downloaded via the serial console port using the
XMODEM protocol. You can download to permanent flash ROM, or you
can download to temporary storage in RAM for test purposes.
Name Function
Power Connector Provides AC power to the switch.
Redundant Power
Connector This connector is provided for a redundant power unit
(RPU) which can supply power to the hub if its primary
power supply fails. (Refer to the manual provided with
the RPU for further details.)
Stack Connectors Allows you to stack up to 6 units to form a dual-speed
network of up to 144 ports.
