2.1 Product Description
The PLANET GSW-1600/GSW-2400 is a 16/24-port 10/100/1000Mbps Ethernet switch
with non-blocking wire-speed performance. With 32/44Gbps internal switching fabric,
the GSW-1600/GSW-2400 can handle extremely large amounts of data transmission in a
secure topology linking to a backbone or high-power servers. The GSW-1600 /GSW-2400
could recognize up to 4K/32K MAC Address table and provides 272 KB /2MB on-chip frame
buffer. The GSW-1600 /GSW-2400 offers wire-speed packet transfer performance without
risk of packet loss. The high data throughput, it can provide the most convenient for user
to upgrade their network to Gigabit environment.
The GSW-2400 also provides 2 Mini-GBIC interfaces for ber extension to uplink to a
server or network backbone.
2.1.1 Product Overview
PLANET GSW-1600/2400 is a gigabit Ethernet switch with 16/24 RJ-45 10/100/1000 Mbps
ports for high-speed network connectivity. The GSW-1600/2400 can also automatically
identify and determine the correct transmission speed and half/full duplex mode of the
attached devices with its 16/24 ports. The Gigabit port can handle large amounts of data
transmission in a secure topology linking to a backbone or high-power servers.
This products also supports store-and-forward forwarding scheme to ensure low latency
and high data integrity, eliminates unnecessary trafc and relieves congestion on critical
network paths. With an intelligent address recognition algorithm, GSW-1600/2400 could
recognize up to 4K/32K different MAC address and enables ltering and forwarding at full
wire speed.

Red Lights to indicate that the fans are not active.
Lights to indicate that the Switch is successfully
connecting to the network.
Blinks to indicate the Switch is actively receiving or
sending the data over the port.
Lights to indicate that the port is operating at 1000
Mbps.
Off to indicate that the port is operating at 100Mbps
or 10 Mbps while the port’s Link is on.
Lights to indicate that the port is operating in full-

2.1.4 GSW-1600/2400 Rear Panel
The rear panel of the Switch indicates an AC inlet power socket, which accepts
input power from 100 to 240VAC, 50-60Hz.
Figure 2-3 Rear Panel of GSW-1600
Figure 2-4 Rear Panel of GSW-2400
Note: To press the button to enable the buzzer (Buzzer on, default), the
buzzer makes continuously alarm noise, as the system is overheating
or Fan failure. If the button is released (Buzzer off ), the buzzer will not
work even if the system overheats or Fan failure.
Power Notice:
1.The device is a power-required device, it means, it will not work 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.
2.2 Installing a GSW-1600/2400
This part describes how to install your GSW-1600/2400 Gigabit Ethernet Switch and make
connections to the switch. Please read the following topics and perform the procedures
in the order being presented. PLANET GSW-1600/2400 Gigabit Ethernet Switch do not
need software conguration. To install your GSW-1600/2400 on a desktop or shelf, simply
complete the following steps.
2.2.1 Desktop Installation
To install a GSW-1600/2400 on a desktop or shelf, simply complete the following steps:
Step1: Attach the rubber feet to the recessed areas on the bottom of the switch.
Step2: Place the GSW-1600/2400 on a desktop or shelf 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 re-
strictions discussed in Chapter 1, Section 4, Specification.
Step4: Connect your GSW-1600/2400 to network devices.

A. Connect one end of a standard network cable to the 10/100/1000 RJ-45 ports
on the front of the GSW-1600/2400.
B. Connect the other end of the cable to the network devices such as printer serv-
ers, 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 GSW-1600/2400.
B. Connect the power plug of the power cable to a standard wall outlet.
When the GSW-1600/2400 receives power, the Power LED should remain solid Green.

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 ltering 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 ltered. Thereby increasing 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 efciency 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 congured in any Ethernet network environment to
signicantly 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 lter packets whose destination address is
on the same segment as the source address. This connes network trafc to its respective
domain, reducing the overall load on the network.

11
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.

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:
Check the cable connection and its quality.
Some stations cannot talk to other stations located on the other port
Solution:
The address table may contain older information than of the address table of
that node. Please power down to refresh the address information.
Performance is bad
Solution:
Check the full duplex status of the partner Switch. The Gigabit Ethernet Switch
is run at full duplex and the partner is set to half duplex, then the performance
will be poor.
