Introduction
Troubleshooting
The Switch can be easily monitored through panel indicators to assist in
identifying problems. This section describes common problems you may
encounter and possible solutions.
The Dyna-Switch/16 and Dyna-Switch/24 (Auto MDI/MDIX) are Fast
Ethernet switches that provide wire-speed, a Fast Ethernet switching
function which allows high-performance, low-cost connections to Full-
duplex, Half-duplex, 10Mbps and 100Mbps Ethernet networks. The
Switches are targeted at workgroup, department, or backbone computing
environments in SME (small, medium enterprise) businesses.
I Power
If the power indicator does not light when the power cord is plugged
in, you may have a problem with the power outlet or cord. However, if
the power LED goes off after running for a while, check for loose power
connections, power losses or surges at the power outlet. Turn off
power, wait 30 seconds and turn power on again. If problem is still
not resolved, call for dealer’s assistance.
These Switches provides auto-sensing 10/100Mbps Ethernet RJ-45 ports
which automatically detect the speed of the device that you plug into them.
This switching function allows 10Mbps, 100Mbps, Full-duplex and Half-
duplex devices to communicate on the same network without having to
replace any infrastructure. This flexible feature allows your network a
timely, economical migration to 100Mbps Fast Ethernet.
I Cabling
Verify that the cabling type is correct. Make sure all cable connectors
are securely seated in the required ports. Use only standard
Unshielded Twisted-Pair (UTP), Category 3, 4, 5, or 5e cables. Use
only Category 5 or 5e when connecting with Fast Ethernet. Make
certain the maximum distance between the Switch and what it’s
connected to is 100 meters or less.

Hardware Description
For enterprise networks where large data broadcasts are constantly
processed, these switches are an ideal solution for department users to
connect to the corporate backbone.
The Front Panel
The Front Panels of the Dyna-Switch/16 and 24 consist of
10/100Base-TX RJ-45 ports and LED Indicators.
In the illustration below, two Ethernet switches, with PCs, print servers,
and a local server attached, are both connected to a Dyna-Switch. All of
the devices in this network can communicate with each other through
the Dyna-Switch. Connecting servers to the switch allows other users to
access the server’s data.

The 3-pronged power plug is located at the rear panel of the
switches as shown in the Figure 3. The Switch operates on AC in the
range 100-240V AC, 50-60Hz.

This section provides a few samples of network topology in which the
Switches are used. The Dyna-Switch/16 and 24 are designed to be
used as segment switches. With their large address tables (8K MAC
address) and high performance, they are ideal for interconnecting
networking segments.
You can use the Dyna-Switch/16 and 24 to connect PCs, workstations,
and servers to each other by connecting these devices directly to a
Switch. The switch automatically learns node addresses, which are
subsequently used to filter and forward all traffic based on the
destination address.
