cabling will be limited to 5 meters (16 feet). The only way to extend the inter-
hub cabling, would therefore be to reduce the length of the cabling used to
attach the end nodes to the hubs.
• Ethernet Switch - There are no formal restrictions on cascade length if a
device is connected to a switch, which effectively breaks up the collision
domain. When a collision domain is broken up by a device like a switch,
cascade length is limited only by the time-out requirements of the particular
applications running over the network.
Powering On the Hub
1. Plug the power cord into the power socket at the rear of the hub, and the
other end into a power outlet.
2. Check the LED marked Power on the front panel to see if it is on. The unit will
automatically select the setting that matches the connected input voltage.
Therefore, no additional adjustments are necessary when connecting it to any
input voltage within the range marked on the rear panel.
3. The hub performs a self-diagnostic test upon power-on.
Note: The unit supports a "hot remove" feature which permits you to connect/
disconnect cables without powering off the hub and without disrupting the
operation of the devices attached to the hub.
Verifying Port Status
Check each connection by viewing the port status indicators shown in the
