Powering On the Switch
1. Plug the power cord into the power socket at the rear of the switch, and the other
end into a power outlet.
2. Check the LED marked PWR 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
about 50 seconds to complete.)
Note
: The unit supports a "hot remove" feature which permits you to connect/
disconnect 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 status indicators shown in the following
figure and 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:
Both sides of each connection must use the same communication mode (i.e., half or
full duplex). If any device connected to an RJ-45 port does not support auto-
negotiation and needs to operate at full duplex, then you must manually set the
communication mode using the Configure button.
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).
Configuring the Switch
The communication mode for all ports must be set to the same mode used by the
connected device. All RJ-45 ports can use auto-negotiation to determine the
communication mode. However, if any device connected to these ports does not
support this feature and needs to operate at full duplex, then you must manually set the
communication mode for the concerned port to full duplex using the Configure button.
Notes
: 1. Full duplex can only be used for a dedicated link. When connecting to a
shared collision domain (e.g., a repeater hub) be sure the communication
mode is set for half duplex.
2. This switch uses the Nways standard for auto-negotiation.
The Configure button can be used to set the communication mode for any port. However,
you can also connect a terminal or PC to the Console port on the rear panel, and
perform the following tasks:
Enable/Disable any port
Set the communication mode for any port
Set the switching mode
Configure SNMP parameters
Configure VLAN port grouping
Enable and configure the Spanning Tree Algorithm
Restart the system
Note
: Refer to the Advanced Reference Guide for information on how to connect to
the console port and use the on-board configuration program.
Using the Configure Button
Use the Configure button to set the display mode, perform diagnostics or a
demonstration, and configure the communication mode. Use a long press (2 seconds)
on the Configure button to initiate mode selection, then use a short press (less than 1
second) to move from one mode to the next. The following functions are accessed in
sequence:
Port Status
Displays the status of each port during normal operation -
including collision, transmit, receive and link indications.
Bandwidth Utilization
The percentage of LAN bandwidth utilized.
Forwarding Ratio
The percentage of packets that are forwarded to other ports.
Filtering Ratio
The percentage of packets filtered because the destination is
in the current segment.
Demonstration
Lights all indicator LEDs to verify operation.
Diagnostics
Tests the status of various system components.
Duplex Mode
Sets port communication mode to auto-negotiation, full-duplex
or half-duplex operation.
Setting the Communication Mode
When Full/Half has been selected, use a long press to activate configuration. Note that
when the Configure button is released, the current communication mode selections are
displayed by the Full-Duplex LEDs for each port (i.e., lit: full duplex, unlit: half duplex,
and blinking: auto-negotiation), and the Select LED for Port 1 will begin to blink. To
change modes, use a short press on the Configure button and then use a long press to
implement the setting and move on to the next port. When finished, use a long press to
terminate communication mode selection.
