FCC Class A Compliance
This equipment generates and uses radio frequency energy. If it
is not installed and used properly in strict accordance with the
manufacturer’s instructions, it may cause interference to radio
and television reception. It has been type-tested and found to
comply the specifications in sub- part J of Part 15 of FCC Rules,
which are designed to provide reasonable protection against
such interference in a residential installation. There is no
guarantee that interference will not occur in a particular
installation. If this equipment does cause interference to radio
or television reception which can be determined by turning the
equipment off and on, the user is encouraged to try to correct
the Interference by one or more of the following measures:
Re-orient the receiving antenna
● Relocate the computing device with respect to the receiver
● Move the computer away from the deceiver
● Plug the computer into a different outlet so that compute and
receiver are on different electrical circuits.
If necessary the user should consult the dealer or
an experienced radio or television technician for additional
suggestions.

Introduction
The 16/24-port Ethernet Switches are designed to allow
simultaneous transmission of multiple packets via an
internal high-speed data channel. This means that it can
partition a network more efficiently than bridges or routers
in most environments. This 16/24-port Ethernet switching
is a highly reliable network switch and is the ideal device
for bridging Ethernet to Fast Ethernet workgroups or
networks. Simple and cost-effective, the 16/24-port
Ethernet Switching supports IEEE802.3u, IEEE802.3,
100Base-TX. And 10Base-T. the 16/24-port Ethernet
Switching is therefore fast being recognized as one of the
most important building blocks for today networking
technology.
The front panel of the 16/24-port Ethernet Switches
provide LEDs for easy recognition of the operation status
and troubleshooting. These LEDs indicate the status of
system power and per port link, including link, speed,
collision, full/half-duplex, and receive status.
The 16/24-port Ethernet Switches are specially designed
for connecting workgroup devices and desktops, with low
cost and flexibility for backbone implementations. Instead,
companies can deploy scaleable, affordable switches that
increase the aggregate bandwidth of the network by
boosting throughput to the workgroups that need it most.
