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.

Chapter 2: Overview
2. Overview
2.1 Introduction
The 24-Port Web Smart Gigabit Ethernet Switch provides 24 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 increases
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 rackmount 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-based VLAN.
• Supports priority queues for QoS.
• Complies with IEEE 802.3 Ethernet, IEEE 802.3u Fast Ethernet, and IEEE 802.3ab
Gigabit Ethernet standards.
• 24 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.
• Supports broadcast storm filitering.

Chapter 3: Software Description
• MAC Address: Displays the unique hardware address assigned by manufacturer
(default).
• S/W Version: Displays the switch’s firmware version.
• H/ W Version: Displays the switch’s hardware version.
• DHCP Enabled: Click the box to enable DHCP.
• Fallback IP address: Manually assign the IP address that the network is using.
The default IP is 192.168.2.1.
• Fallback Subnet Mask: Assign the subnet mask to the IP address.
• Fallback Gateway: Assign the network gateway for industrial switch. The default
gateway is 0.0.0.0.
• Management VLAN: ID of a configured VLAN (1–4096) through which you can
manage the switch. By default, all ports on the switch are members of VLAN 1.
However, you change the management VLAN, the management station must
be attached to a port belonging to this VLAN.
• Name: Type in a unique name to identify the switch.
• Password: Type in the new password (the default value is “admin”).
• SNMP Enabled: Enables or disables SNMP on the switch. Supports SNMP version
1 and 2c management clients.
• SNMP Trap Destination: IP address of the trap manager to receive notification
messages from this switch. Traps indicating status changes are issued by the
switch to specified trap managers. You must specify trap managers so that key
events are reported by this switch to your management station.
• SNMP Read Community: A community string that acts like a password and
permits access to the SNMP database on this switch. Authorized management
stations are only able to retrieve MIB objects.
• SNMP Trap Community: Community string sent with the notification operation.
