Selecting Display Modes
The Status display mode is the default, when this LED is lit, the Port Status Display LEDs
provide information on packet collisions (for ports set at half duplex), transmission
speed, port activity, communication mode, and link status.
The other statistical display modes (Util%, Forward%, Filter%) use the whole LED
display to indicate values (1% to 90
+
%) 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.

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 an Ethernet or Fast Ethernet hub, 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 or a 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 the address of each node and then uses these addresses to filter
and forward traffic. 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 from one segment to another (i.e., different ports on the switch), the
high-speed switching fabric forwards the packets at near zero latency.
Switching Functions
- Adaptive cut-through switching is used to forward traffic to
other ports. This scheme optimizes system performance, while ensuring data integrity,
by automatically selecting the best scheme to use based on the current traffic load.
Flexible Configuration
- This switch is not only designed to segment your network,
but also to provide a wide range of options in setting up network connections. It can be
used as a simple stand-alone switch; or can be connected with standard repeater
hubs, switches, or other network interconnection devices in various configurations.
