FEDERAL COMMUNICATIONS COMMISSION and
INDUSTRY CANADA RADIO FREQUENCY INTERFERENCE STATEMENTS
Class B Digital Device. This equipment has been tested and found to comply with
the limits for a Class B computing device pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation. However, there is no guarantee that
interference will not occur in a particular installation. This equipment generates,
uses, and can radiate radio frequency energy, and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. If this equipment does cause harmful interference to radio or
telephone reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one of the
following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult an experienced radio/TV technician for help.
CAUTION:
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
To meet FCC requirements, shielded cables and power cords are required to
connect this device to a personal computer or other Class B certified device.
This digital apparatus does not exceed the Class B limits for radio noise emission
from digital apparatus set out in the Radio Interference Regulation of Industry
Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant
les limites applicables aux appareils numériques de classe B prescrites dans le
Règlement sur le brouillage radioélectrique publié par Industrie Canada.

Chapter 2: Overview
2. Overview
2.1 Introduction
The 16-Port Web Smart Gigabit Ethernet Switch provides 16 10-/100-/1000-Mbps
ports. It is designed for easy installation and enables high performance in an
environment where traffic on the network and the number of users increase
continuously. With the newest Gigabit chipset, this 19" Gigabit Ethernet switch
fully supports the highest speed without any problems, even when running
full-duplex fully loaded.
The switch also provides automatic crossover detection on each port, making it
easy to uplink to another switch without using a crossover cable.
This rackmountable switch is specifically designed for medium to large
workgroups. It provides smooth network migration and makes it easy to increase
network capacity.
2.2 Features
• Supports real-time status (link, speed, duplex) of each port.
• Supports port setting for enable or disable operation (the first port can’t be
disabled).
• Includes port setting for N-Way or force mode operation.
• Features Broadcast Storm Protection.
• Enables Port-basesd VLAN.
• Supports priority queues for QoS.
• Complies with IEEE 802.3 Ethernet, IEEE 802.3u Fast Ethernet, and IEEE 802.3ab
Gigabit Ethernet standards.
• 16 ports autonegotiate speeds of 10, 100, and 1000 Mbps.
• 19" rackmountable.
• Provides non-blocking and non-head of line blocking full wire-speed
forwarding.
• Store-and-forward operation support.
• Supports 9.6 KB jumbo frames.
• Provides 8K MAC addresses.
