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 transmission mode for all ports must be set to the same mode used by the
connected device (i.e., half or full duplex). The fiber optic ports must be manually
configured, but the RJ-45 ports can use auto-negotiation to set the transmission mode.
However, if any device connected to an RJ-45 port must operate at full duplex, be sure
it supports auto-negotiation. If it does not, then manually set the communication mode
for the switch port using the Configure button or a console connection.
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 Shows the percentage of LAN bandwidth utilized.
Demonstration Lights all indicator LEDs to verify operation.
Diagnostics Tests the status of various system components.
Select Mode Sets communication mode to auto-negotiation; or sets the
communication mode to half/full duplex and speed to 10/100 Mbps.
Selecting Display Modes
Port Status mode is the default.
When this LED is lit, the indicators
provide information on packet
collisions (for ports set at half
duplex), communication speed,
port activity, communication mode,
and link status.
Bandwidth Utilization mode (UTIL%)
uses the whole LED display to indicate
values (1% to 65
+
%) for each port.
When active, these LEDs behave
like a stereo's equalizer display.
System Diagnostics
Enabling the DIAG function activates a two-stage
self-diagnostic test, similar to the one performed
upon power on. The first stage is the System
Diagnostic Test, and the second stage is the Port
Diagnostic Test. If the test is not completed
successfully, the corresponding LEDs (described
below) will blink after test completion to indicate
which component failed the test.
Setting the Port Speed and Communication Mode
When the Select LED is lit, use a long press
to activate configuration. Note that when the
Configure button is released, the current
communication mode selections are displayed
by the 100M and Full LEDs for each port (as
indicated in the following table), 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 configuration.
The switch also includes a menu-driven configuration program which can be accessed
by attaching a VT100 compatible terminal or a PC running a terminal emulation program
to the console port on the back of the switch. Use the null-modem cable provided with
this package, or use a null modem connection that complies with the wiring assignments
shown in the back of this guide.
When attaching to a PC, set terminal emulation type to VT100, specify the port used by
your PC (i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit, no parity,
and 9600 bps (for initial configuration). Also be sure to set flow control to "none."
Once a direct connection to the console port is established, you will have access to the
menu items shown below.

Notes: 1. Factory defaults are auto-negotiation for RJ-45 ports, and 100Mbps and half
duplex for fiber optic ports.
2. Full duplex can only be used for a dedicated link. When connecting to a
shared collision domain (e.g., a repeater hub), half duplex must be used.
3. This switch uses the Nways standard for auto-negotiation.
4. Factory default has all ports in VLAN Group 1, with all other groups empty.
Applications
This switch segments your network, significantly increasing both bandwidth and
throughput. Any port on the switch can be attached to a hub (i.e., shared collision
domain) or provide a dedicated link to a single network device (e.g., a workstation).
When a port on the switch is connected to a hub (i.e., a 10 or 100 Mbps repeater), the
bandwidth provided by that port is shared by all the devices connected to the attached
hub. However, when a port is connected to an end node or to a device that breaks up
the collision domain (e.g., another switch, bridge or router), the attached device has
access to the full bandwidth provided by that port.
Bridging Functions - This switch provides fully transparent bridging functions. It
automatically learns node addresses, that are subsequently used to filter and forward
all traffic based on the destination address. When traffic passes between devices
attached to the same shared collision domain, those packets are filtered from the switch.
But when traffic must be passed between unique segments (i.e., different ports on the
switch), the high-speed switching fabric forwards the packets at near zero latency.
