Installing the Switch
7
Powering On the Switch
1. Plug the power cord into the power socket on the rear of the switch, 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 switch performs a self-diagnostic test upon power-on. (Note that this test
takes several minutes to complete.)
Note: The unit supports a “hot remove” feature which permits you to connect or
disconnect twisted-pair or fiber cables without powering off the switch and without
disrupting the operation of the devices attached to the switch.
Verifying Port Status
Check each connection by viewing the port indicators shown in the following table.
Verifying System Operation
Verify that all attached devices have a valid connection. The switch monitors the link
status for each port. If any device is properly connected to the switch and
transmitting a link beat signal, the Link indicator will light up for the corresponding
port. If the Link indicator fails to light when you connect a device to the switch, check
the following items:
• Be sure all network cables and connectors are properly attached to the connected
device and the switch.
• See if your cable is functioning properly by using it for another port and attached
device that displays valid indications when connected to the network.
• Be sure no twisted-pair cable exceeds 100 meters (328 feet).
