1INTRODUCTION
OVERVIEW
The EZ Switch 10/100/1000, SMCGS805, is a powerful, high-performance
Gigabit Ethernet switch with eight RJ-45 ports. The switch supports autonegotiation 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 straightthrough 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.
PACKAGE CONTENTS
Before installing the switch, verify that you have all the items listed in the
package contents. If any of the items are missing or damaged, contact your
local SMC distributor. Also be sure you have all the necessary tools and cabling
before installing the switch.
The following contents should be found in your package:
◆One SMCGS805 switch
◆One external power adapter
◆Wall mount Kit

IEEE 802.1P QOS
The SMCGS805 switch supports 802.1p priority queuing Quality of Service,
which is an implementation of the IEEE 802.1p standard. With the 802.1p QoS
function, you can reserve bandwidth for important functions that require a lot of
bandwidth or have a high priority, such as VoIP (Voice-over Internet Protocol),
web browsing applications, or video conferencing. The switch has separate
hardware queues on each physical port to which packets from various
applications are mapped and priorities assigned.
The illustration below shows how 802.1p priority queuing is implemented on the
switch.
Figure 1: Mapping QoS on the Switch
Tag untag01234567
Priority Queue
Weight Value1248
TC0TC1TC2TC3
There are four priority queues labeled TC0, TC1, TC2 and TC3. The untagged
packets and the eight IEEE 802.1p priority values (defined by the standard) are
mapped to the four priority queues on the switch. TC3 has the highest priority of
the four priority queues, while TC0 has the lowest priority. The untagged packets
and eight priority values, specified in IEEE 802.1p, are mapped to the switch’s
priority queues as follows:
◆Untagged packets, and packets with priority 1 and 2 are assigned to the
switch’s TC0 queue.
◆Packets with priority 0 and 3 are assigned to the switch’s TC1 queue.
◆Packets with priority 4 and 5 are assigned to the switch’s TC2 queue.
◆Packets with priority 6 and 7 are assigned to the switch’s TC3 queue.
The switch uses Weighted Robin Round (WRR) for scheduling. The WRR queuescheduling algorithm schedules all the queues in turn with every queue assured
a certain service time. For WRR mode, the default weight values of TC0, TC1,
TC2 and TC3 are 1:2:4:8.

LOOPBACK DETECTIONAND PREVENTION
When a loop occurs at a port, the switch will
■
Block the loop port, automatically protecting the switch.
■
Flash the port LED twice every second.
■
Turn the Loop LED on red.
When the loop clears the port LED will cease flashing and the Loop LED will turn
off.

PRIVATE VLAN SUPPORT
The switch 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.
The switch ports each have a fixed default VLAN ID, with Port 1 fixed as a VLAN
trunk port. The figure below indicates the VLAN IDs assigned to each switch
port. Note that Port 1 is the uplink port and must be connected to a switch or
router in the service provider network.

Installation
INSTALLATION
When installing the switch, follow these guidelines:
◆Place the switch in an appropriate ventilated environment. A minimum of 25
mm space around the unit is recommended.
◆Place the switch and connected cables away from sources of electrical noise,
such as radios, transmitters, and broadband amplifiers.
◆Be sure the switch is placed away from moisture and locations that do not
conform to its recommended environmental specifications.
PC CONNECTIONS
Connect each PC to the switch using twisted-pair Ethernet cables with RJ-45
connectors at each end. Plug one RJ-45 connector into an RJ-45 port on the
switch, and plug the other RJ-45 connector into a PC's network port.
SWITCH CONNECTIONS
When making switch interconnections, you can use any port on the switch to
connect to another switch using straight-through or crossover cable. As all ports
on the switch support Auto MDI/MDIX, you can use straight-through cables for
all connections.

properly.
◆Make sure the power source is ON.

C
ORRESPONDING PORT
◆Make sure that the cable connectors are firmly plugged into the switch and
the device.
◆Make sure the connected device is turned on and working properly.
◆The cable must be less than 100 meters long (328 feet).
◆Check the port on the attached device and cable connections for possible
defects. Replace the defective cable if necessary.
POWERAND COOLING PROBLEMS
If the power indicator does not turn on when the power cord is plugged in, you
may have a problem with the power outlet, power cord, or internal power
supply. However, if the unit powers off after running for a while, check for loose
power connections, power losses or surges at the power outlet. If you still
cannot isolate the problem, the internal power supply may be defective.
