Auto-Negotiation for optimal speed detection through RJ-45 Category  
6, 5 or 5e cables. Support is standard for Auto-MDI/MDI-X that can  
detect the type of connection to any Ethernet device without requiring  
special straight or crossover cables.  
The Flow Control function allows your Gigabit switch supported  
routers and servers to directly connect to this switch for fast, reliable  
data transfer.  
 
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.

Note: This switch does not need software configuration.  
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.

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::
