9-PORT PERSONAL MINIHUB
3.3 Cascading
You can cascade 9-Port Personal MiniHubs in order to expand networks.
For example, you can set a MiniHub’s Up-Link switch to the “
=
x
=
”
position, then run 10BASE-T cable from the MiniHub’s rear-panel port to
any port of another 10BASE-T hub, as shown in the illustration below.
Since each 9-Port Personal MiniHub provides full repeater functionality,
cascaded units can operate together even though there may be a full
segment of distance between them. To satisfy the “four repeater rule”
defined by Ethernet standards, you shouldn’t place more than four hubs or
repeaters in any path between two users on the same network.
NOTE
If you run cable between the rear ports of two 9-Port Personal Mini-Hubs,
as shown with the upper two units in the illustration below, set the
Up-Link switch of only one of the units to the “
=
x
=
” position—the other
unit’s switch must remain set to the “=== ” position for the link to work
properly.
