Introduction
General Description
This Switch will instantly boost your networking throughput because it provides
you with 24 Gigabit ports that enable true Gigabit connectivity. Users are now
able to transfer large and bandwidth-hungry files faster and hence get a real
efficiency improvement. This efficiency is further enhanced by the user-friendly
Web-based management interface. In addition to the 24 copper ports, the
Switch offers 4 fiber ports (slots) that can be used in the place of the last 4
copper ports (these are interchangeable or ‘combo’ ports). These SFP
module slots offer the option of a long-distance, fiber-based connection. Use of
a SFP module port automatically disables its corresponding copper port.
The management functions enable efficient network usage. VLAN reduces the
collisions caused by broadcasting. Port Aggregation enlarges the bandwidth of
the backbone connection. QoS secures the bandwidth for some
bandwidth-hungry applications like VoIP and video conferencing. The Switch
also supports 802.3x and backpressure flow control mechanisms to ensure the
correctness of data transmission.

Description of Switch Functions
Jumbo Frame
The Signamax 065-7940B-WS Switch supports Jumbo Frames, which means that it
can transmit the same data in fewer frames. This helps to ensure fewer overheads,
shorter processing time, and fewer interruptions.
NOTE: To enable Jumbo Frame, Flow Control should be enabled in advance.
Flow Control and Backpressure
Flow Control and Backpressure both help devices with different processing speeds to
communicate with each other. This ensures the correctness of data transmissions.
The 802.3x Flow Control and Backpressure mechanisms work respectively for full-
and half-duplex modes. Flow Control can be enabled or disabled on a per-port basis.
Mirror
The Mirror function enables network administrators to monitor all traffic. By forwarding
a copy of the packets that are transferred by the monitored port, the sniffer port
receives all the packets and hence is able to monitor the traffic through the specified
port.
VLAN
This Switch supports Virtual LAN, which means the network can be segmented into
groups to reduce collisions caused by wide broadcasting. The Switch supports both
port-based VLAN and 802.1q tag-based VLAN. Port-based VLAN directs incoming
packets to VLANs according to their ingress ports. 802.1q-based VLAN adds a tag to
the header of the packet to direct the packet to the right VLAN.
Trunk (Aggregation)
The Trunk function groups several ports into one combined transmission channel.
This increases the bandwidth, which helps to boost backbone connectivity. The
Switch allows a maximum of 4 groups and 8 members for each group.
Quality of Service (QoS)
QoS classifies packets into different precedence classes. The packets are transmitted
and received according to their classified priorities. This mechanism helps
high-bandwidth demanding applications such as VoIP to get an unobstructed
connection.
SNMP
The Switch supports SNMP (Simple Network Management Protocol). It allows the
product to be monitored by an SNMP management station.
