1.1 Checklist

Check the contents of your package for following parts:

l

FGSW-2402S.

l User's manual.
l Power cord.
l

19” rack mount brackets.

l RS-232 cable.

If any of these pieces are missing or damaged, please contact your
dealer immediately. If possible, retain the carton including the original
packing material, and use them against to repack the product in case
there is a need to return it to us for repairing.

1.2 About the Switch

With two open slots available for fiber or copper Gigabit modules, the
FGSW-2402S can accelerate your Cat5 backbone to 10 times the
performance of existing 100 Megabit without re-wiring your cabling
infrastructure. The optional Gigabit modules can be Gigabit fiber-optic,
(SX or LX) and also Fast Ethernet fiber-optic up to 10 kilometers away.
Powered by a non-blocking 9.6Gbps backplane, the FGSW-2402S
simplifies the task of upgrading your LAN to cater for increased
bandwidth demand.

Equipped with a console interface the Gigabit Smart Switch can be
programmed for basic switch management functions such as
bandwidth provision, port status configuration, VLAN parameters,
port-trunking, and port monitoring.

The switch is suitable for the following applications:

Workgroup switch:

By installing a Gigabit copper NIC such as PLANET’s ENW-9601T
(32/64-bit PCI Gigabit Ethernet Adapter), upgrading your
workgroups or servers from Ethernet or Fast Ethernet to Gigabit
Ethernet is simple, ensuring compatibility for current and future
networks and protecting your network investment.

Department Switch:

With a proven Gigabit Ethernet Interface, there has never been a
better time to connect your workgroups to the backbone using the
4-pair CAT 5/5e UTP cables that already exist in your building.
IEEE802.3x flow-control is enabled to ensure high performance
Gigabit trunking (up to 4Gbps bandwidth) without any loss of
network packets. The choice of Gigabit fiber optic modules includes
LX to extend network reach where required.

MTU Switch:

In an MTU/MDU application, the advanced functionality of the
FGSW-2402S eliminates traditional problems associated with the
use of Ethernet. Users can be segregated with advanced VLAN
functionality and the unique ‘MTU switch mode’ to enhance security,
and bandwidth managed with tiered bandwidth provision and control
using configurable 9 levels of upstream/downstream restriction.
This, couple with the flexible 100FX, 1000SX/LX/T module options
make the FGSW-2402S one of the best and most cost-effective
MTU switch solutions for Multi-tenant service providers.

Power Notice:

1. The device is a power-required device, it means, it will not
operate till it is powered. If your networks should active all the
time, please consider using UPS (Uninterrupted Power Supply)
for your device. It will prevent you from network data loss or
network downtime.

2. In some area, installing a surge suppression device may also
help to protect your switch from being damaged by unregulated
surge or current to the Switch or the power adapter.

4. SWITCH OPERATION

4.1 Address Table

The Switch is implemented with an address table. This address table
composed of many entries. Each entry is used to store the address
information of some node in network, including MAC address, port no,
etc. This information comes from the learning process of Ethernet
Switch.

4.2 Learning

When one packet comes in from any port, the Switch will record the
source address, port no. and the other related information in address
table. This information will be used to decide either forwarding or
filtering for future packets.

4.3 Forwarding & Filtering

When one packet comes from some port of the Ethernet Switching, it
will also check the destination address besides the source address
learning. The Ethernet Switching will lookup the address-table for the
destination address. If not found, this packet will be forwarded to all
the other ports except the port which this packet comes in. And these
ports will transmit this packet to the network it connected. If found, and
the destination address is located at different port from this packet
comes in, the Ethernet Switching will forward this packet to the port
where this destination address is located according to the information
from address table. But, if the destination address is located at the
same port with this packet comes in, then this packet will be filtered.
Thereby increasing the network throughput and availability.

4.4 Store-and-Forward

Store-and-Forward is one type of packet-forwarding techniques. A
Store-and Forward Ethernet Switching stores the incoming frame in
an internal buffer, do the complete error checking before transmission.
Therefore, no error packets occurrence, it is the best choice when a
network needs efficiency and stability.

The Ethernet Switch scans the destination address from the
packet-header, searches the routing table provided for the incoming
port and forwards the packet, only if required. The fast forwarding

makes the switch attractive for connecting servers directly to the
network, thereby increasing throughput and availability. However, the
switch is most commonly used to segment existing hubs, which nearly
always improves overall performance. A Ethernet Switching can be
easily configured in any Ethernet network environment to significantly
boost bandwidth using conventional cabling and adapters.

Due to the learning function of the Ethernet switching, the source
address and corresponding port number of each incoming and
outgoing packet are stored in a routing table. This information is
subsequently used to filter packets whose destination address is on
the same segment as the source address. This confines network
traffic to its respective domain, reducing the overall load on the
network.

The Switch performs "Store and forward" therefore, no error packets
occur. More reliably, it reduces the re-transmission rate. No packet
loss will occur.

4.5 Auto-Negotiation

The STP ports on the Switch have built-in “Auto-negotiation”. This
technology automatically sets the best possible bandwidth when a
connection is established with another network device (usually at
Power On or Reset). This is done by detect the modes and speeds at
the second of both device is connected and capable of, Both
10Base-T and 100Base-TX devices can connect with the port in either
Half- or Full-Duplex mode. 1000Base-T and 1000Base-SX can only
connected in Full-duplex mode.

5. TROUBLESHOOTING

This chapter contains information to help you solve problems. If Giga
Switch is not functioning properly, make sure the Ethernet Switch was
set up according to instructions in this manual.

The Link LED is not lit

Solution:

Some stations can not talk to other stations located on
The other port

Solution:

Performance is bad

Solution:

Check the cable connection and remove duplex mode of the Giga
Switch

The address table may contain older information than of the address
table of that node. Please power down to refresh the address
information

Check the full duplex status of the Ethernet Switch. If the
Ethernet Switch is set to full duplex and the partner is set to
half duplex, then the performance will be poor.
