Installing the System
from node to node is 367m - (2 x 72m) = 223m (732 ft). Therefore, if both
node A and B are linked to separate repeaters in a two hub system, each using
100 meters (328 feet) of cable to connect to their respective hub, then the inter-
hub cabling will be limited to 23 meters (75 feet), i.e., 223m - 2x100m = 23m,
as illustrated in Figure 3-2.
Providing Power to the EtherHub
1.
Power on the hub by plugging the power cord into the power socket at the
rear of the EtherHub, 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.
F
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 attached devices.
Verifying Port Status
Check each connection by viewing the port status indicators listed below. (For
a more detailed description of these indicators, refer to Chapter 4.)
Link
Indicates that the port has established a valid network connection.
Traffic
Indicates traffic traversing the port.
Partition
Indicates that the port has been isolated from the hub when pre-
defined collision threshold has been reached.
If the Link status indicator is not functioning properly, or you experience any
other difficulties in setting up the hub, refer to Appendix A.
