Hardware Description

This product series provide two different running speed – 10Mbps and
100Mbps in the same hub and automatically distinguish the speed of
incoming connection and group the same speed ports in a network segment,
i.e., each port has auto-negotiation Nway function.
Both DHR-800P and DHR-800 products have dual-speed Nway function,
but only DHR-800P with switching function to bridge 10Mbps and
100Mbps segments.
The DHR-800 series product can stack up each other, but in a stack only
ONE DHR-800P primary hub is allowed. It means that in a stack you can
have several DHR-800 hubs then all ports with dual-speed auto sensing
function, but 10Base and 100Base segments can not link together. Now by
adding one DHR-800P hub to this stack, 10 and 100 segments can
communicate through inside switch module.
This section describes the important parts of the 10/100BASE-TX Dual-
Speed Ethernet hub. It presents front panel and rear panel drawings of the
product showing the LED indicators, connectors, and switches.
