EZ Switch
TM
8-Port Gigabit Ethernet Switch
Product Overview
The EZ Switch 10/100/1000, SMCGS805, is a powerful, high-performance Gigabit Ethernet switch with eight RJ-45 ports. The
switch supports auto-negotiation on all ports, which means they automatically negotiate with connected partners to determine
the network speed (10/100/1000 Mbps) and duplex mode (full or half duplex).
The auto-sensing ability of the ports provides an easy way to migrate from 10/100 Mbps to a 1000 Mbps network. The switch
also supports Auto-MDI/ MDIX, so each port can be connected to PCs or other switches using only straight-through cables.
Crossover cables are not needed.
Store-and-forward switching provides low latency while eliminating error packets on the network. Also, the switch supports
pre-standard IEEE 802.3az Energy Efficient Ethernet that saves power consumption.
Key Features and Benefits
IEEE 802.3az Energy-Efficient Ethernet Support
When two 802.3az-compliant switches are connected, up to
76%* of power consumption can be saved.
Support for IEEE 802.1p Quality of Service
The switch supports 802.1p Quality of Service, which is
important in implementations where time-sensitive data, such
as voice and video, are streamed across the network.
Private VLANs
The switch supports a private VLAN feature, which is
designed for Internet access deployment where subscriber
end nodes are connected to an Internet Service Provider
network through the switch. In this application, each port is
isolated in its own private VLAN to provide security for each
end user, only the uplink port (Port 1) can communicate with
all other ports. Ports 2-8 cannot communicate with each other.
Broadcast Storm Control and CRC Filtering
Broadcast storm control prevents broadcast traffic storms from
consuming bandwidth, and CRC filtering stops bad packets
from propagating throughout the network.
Loopback Detection and Prevention
When a loop occurs, the switch blocks the loop port
automatically, protecting the switch and indicating the port that
has the loop issue with the port LED.
Support for Jumbo Packets
Support for Jumbo packets of up to 9K Bytes in size.
Auto MDI/MDI-X on Each Port
Support for Auto-MDI/MDIX means that no crossover cables
are required. Straight-through cables can be used for all
connections.
