2.1.1 Product Overview
The PLANET GSW-2401 and GSW-1601 are Gigabit Ethernet
switches with 24/16 RJ-45 10/100/1000 Mbps ports for high-speed
network connectivity. The switches can also automatically identify and
determine the correct transmission speed and half/full duplex mode of
the attached devices with its 24/16 ports. The Gigabit port with jumbo
frame feature supported, can handle extremely large amounts of data
transmission in a secure topology linking to a backbone or high-power
servers.
This product also supports store-and-forward forwarding scheme to
ensure low latency and high data integrity, eliminates unnecessary
traffic and relieves congestion on critical network paths. With an
intelligent address recognition algorithm, the switches could recognize
up to 8K different MAC address and enables filtering and forwarding at
full wire speed.

2.2.1 Desktop Installation
To install the switch on desktop, simply follow the next steps:
Step1: Attach the rubber feet to the recessed areas on the bottom of
the switch.
Step2: Place the switch on desktop near an AC power source.
Step3: Keep enough ventilation space between the switch and the
surrounding objects.
Note: When choosing a location, please keep in mind the
environmental restrictions discussed in Chapter 1, Section 1.4
Product Specification.
Step4: Connect your switch to network devices.
A. Connect one end of a standard network cable to the
10/100/1000 RJ-45 ports on the Back of the switch.
B. Connect the other end of the cable to the network devices such
as printer servers, workstations or routers…etc.
Note: Connection to the switch requires UTP Category 5 network
cabling with RJ-45 tips. For more information, please see the Cabling
Specification in Appendix A.
Step5: Supply power to the switch.
A. Connect one end of the power cable to the switch.
B. Connect the power plug of the power cable to a standard wall
outlet.
When the switch receives power, the Power LED should remain solid
Green.

2.2.2 Rack Mounting
To install the switch in a 19-inch standard rack, follow the instructions
described below.
Step1: Place your GSW-2401/GSW-1601 on a hard flat surface, with
the front panel positioned towards your front side.
Step2: Attach a rack-mount bracket to each side of the Switch with
supplied screws attached to the package. Figure 2-3 shows how to
attach brackets to one side of the Switch.
Figure 2-3 Attaching the brackets to the GSW-2401/GSW-1601
Caution:
You must use the screws supplied with the mounting brackets.
Damage caused to the parts by using incorrect screws would
invalidate your warranty.
Step3: Secure the brackets tightly.
Step4: Follow the same steps to attach the second bracket to the
opposite side.
Step5: After the brackets are attached to the Switch, use suitable
screws to securely attach the brackets to the rack, as shown in Figure
2-4.

3. SWITCH OPERATION
3.1 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.
3.2 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.
3.3 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 increase the network throughput and availability.

3.4 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. An 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 the 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.
3.5 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 can be only connected in
Full-duplex mode.

Implicit implementation of the crossover function within a twisted-pair

the scope of this standard.
A.2 10/100Mbps, 10/100Base-TX
When connecting your 10/100Mbps Ethernet Switch to another switch,
a bridge or a hub, a straight or crossover cable is necessary. Each
port of the Switch supports auto-MDI/MDI-X detection. That means
you can directly connect the Switch to any Ethernet devices without
making a crossover cable. The following table and diagram show the
standard RJ-45 receptacle/ connector and their pin assignments::
