GSW-1656

Product Overview

GSW-1656 is a Gigabit switch that is the ideal solution
for networks that demand a reliable and stable high­bandwidth environment to connect workgroups with
le servers. GSW-1656 has 16 10/100/1000 Mbps Nway
ports of which 4 ports are SFP shared ports. These SFP
ports are Mini-GBIC ports for obtaining long distance
network connectivity via ber optic connections.

With a 32 Gbps backplane, GSW-1656 provides high­speed data transmission through eective buering
to each port. With a store-and-forward switching
architecture the data ow between transmit and
receive nodes is controlled to protect against packet
loss.

Save Power With LevelOne Green Technology

Active Link Detection: A LevelOne Green device can

tell if there is activity on each individual LAN port. If an
8-port switch only has 6 active devices connected to
it, power is saved because no trac is routed to the 2
inactive ports.

Cable Length Detection: The switch is able to detect
the distance of the connected device and adjusts
its power accordingly. For example, if you have a
LevelOne Green switch a computer connected to
a 10-meter cable will consume less power than a
computer connected to a 100-meter cable.

Sleep Mode: The device will enter sleep/standby mode
when the connected devices are powered down and
no active links are detected. This helps save energy
consumption during extended periods of network
inactivity, such as nights,
weekends and holidays.
