OVERVIEW
The SMCGS10P-Smart is a Gigabit Ethernet Layer 2 PoE switch with 8 10/100/
1000BASE-T ports, and 2 Small Form Factor Pluggable (SFP) transceiver slots,
(see "Front Panel" on page 25, Ports 9-10). The SMCGS10P-Smart also provides
PoE power to connected devices.
The switch also includes an SNMP-based management agent, which provides inband access for managing the switch.
Both switches provide a broad range of powerful features for Layer 2 switching,
delivering reliability and consistent performance for your network traffic. It
brings order to poorly performing networks by segregating them into separate
broadcast domains with IEEE 802.1Q compliant VLANs, and empowers
multimedia applications with multicast switching and CoS services.

| Introduction
SWITCH ARCHITECTURE
This switch employs a wire-speed, non-blocking switching fabric. This permits
simultaneous wire-speed transport of multiple packets at low latency on all
ports. The switch also features full-duplex capability on all ports, which
effectively doubles the bandwidth of each connection.
This switch uses store-and-forward switching to ensure maximum data integrity.
With store-and-forward switching, the entire packet must be received into a
buffer and checked for validity before being forwarded. This prevents errors
from being propagated throughout the network.
NETWORK MANAGEMENT OPTIONS
With a comprehensive array of LEDs, the switch provides “at a glance”
monitoring of network and port status. The switch can be managed over the
network with a web browser.
For a detailed description of the management features, refer to the Management
Guide.
POWER-OVER-ETHERNET
All eight RJ-45 ports (1~8) of the SMCGS10P-Smart switch support the IEEE
802.3at standard that enables DC power to be supplied to attached devices
using wires in the connecting Ethernet cable. The total PoE power delivered by
all ports cannot exceed the 75 W power budget.
Any PoE-compliant device attached to a port can directly draw power from the
switch over the Ethernet cable without requiring its own separate power source.
This capability gives network administrators centralized power control for
– 26 –
C
HAPTER

Description of Hardware
devices such as IP phones and wireless access points, which translates into
greater network availability.
For each attached PoE-compliant device, the switch automatically senses the
load and dynamically supplies the required power. The switch delivers power to a
device using the wire pairs in UTP or STP cable. Any RJ-45 port on the switch can
provide up to 30 W of power, but only two ports can deliver 30 W simultaneously
to attached devices without exceeding the switch power budget.
| Introduction
DESCRIPTION OF HARDWARE
10/100/1000BASE-T PORTS
The switch contains 8 RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or
full duplex, and 1000 Mbps full duplex. Because all ports on this switch support
automatic MDI/MDI-X operation, you can use straight-through cables for all
network connections to PCs or servers, or to other switches or hubs. (See
"1000BASE-T Cable Requirements" on page 55.)
Each of these ports support auto-negotiation, so the optimum transmission
mode (half or full duplex), and data rate (10, 100, or 1000 Mbps) can be
selected automatically. If a device connected to one of these ports does not
support auto-negotiation, the communication mode of that port can be
configured manually.
Each port also supports IEEE 802.3x auto-negotiation of flow control, so the
switch can automatically prevent port buffers from becoming saturated.
SFP TRANSCIEVER SLOTS
The Small Form Factor Pluggable (SFP) transceiver slots are independent ports.
The following table shows a list of transceiver types that have been tested with
the switch. For an updated list of vendors supplying these transceivers, contact
your local dealer. For information on the recommended standards for fiber optic
cabling, see "Fiber Optic SFP Devices" on page 53.

2 NETWORK PLANNING
INTRODUCTION TO SWITCHING
A network switch allows simultaneous transmission of multiple packets via noncrossbar switching. This means that it can partition a network more efficiently
than bridges or routers. The switch has, therefore, been recognized as one of
the most important building blocks for today’s networking technology.
When performance bottlenecks are caused by congestion at the network access
point (such as the network card for a high-volume file server), the device
experiencing congestion (server, power user, or hub) can be attached directly to
a switched port. And, by using full-duplex mode, the bandwidth of the dedicated
segment can be doubled to maximize throughput.
When networks are based on repeater (hub) technology, the distance between
end stations is limited by a maximum hop count. However, a switch turns the
hop count back to zero. So subdividing the network into smaller and more
manageable segments, and linking them to the larger network by means of a
switch, removes this limitation.
A switch can be easily configured in any Ethernet, Fast Ethernet, or Gigabit
Ethernet network to significantly boost bandwidth while using conventional
cabling and network cards.

Application Examples
| Network Planning
APPLICATION EXAMPLES
The switch is not only designed to segment your network, but also to provide a
wide range of options in setting up network connections. Some typical
applications are described below.
COLLAPSED BACKBONE
The Gigabit Ethernet Switch is an excellent choice for mixed Ethernet, Fast
Ethernet, and Gigabit Ethernet installations where significant growth is expected
in the near future. In a basic stand-alone configuration, it can provide direct fullduplex connections for up to 10 workstations or servers. You can easily build on
this basic configuration, adding direct full-duplex connections to workstations or
servers. When the time comes for further expansion, just connect to another
hub or switch using one of the Gigabit Ethernet ports built into the front panel,
or a Gigabit Ethernet port on a plug-in SFP transceiver.
In the figure below, the switch is operating as a collapsed backbone for a small
LAN. It is providing dedicated 100 Mbps full-duplex connections to workstations
and 1000 Mbps full-duplex connections to power users, and 1000 Mbps fullduplex connections to servers.

POE CONNECTIONS
The switch is an excellent choice for supplying power to connected PoE devices
such as web cameras, IP telephones, or access points.
The eight RJ-45 ports on the switch can provide up to 30 W of power to a
connected device. The switch can supply 9.37 W simultaneously to eight PoE
devices among the eight Gigabit Ethernet ports, or 30 W simultanesously to two
connected PoE devices. The total power cannot exceed the 75 W PoE power
budget.
In the figure below, the switch is supplying power to three PoE devices. It is also
providing dedicated 1000 Mbps full-duplex data connections to these devices. In
addition, other non-PoE devices can be connected to the switch.

REMOTE CONNECTIONS WITH FIBER CABLE
Fiber optic technology allows for longer cabling than any other media type. A
1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a
1000BASE-LX (SMF) link up to 10 km, a 1000BASE-LH link up to 80 km, and a
100BASE-FX (SMF) link up to 20 km. This allows the switch to serve as a
collapsed backbone, providing direct connectivity for a widespread LAN.
The figure below illustrates the switch connecting multiple segments with fiber
cable.

MAKING VLAN CONNECTIONS
This switch supports VLANs which can be used to organize any group of network
nodes into separate broadcast domains. VLANs confine broadcast traffic to the
originating group, and can eliminate broadcast storms in large networks. This
provides a more secure and cleaner network environment.
VLANs can be based on untagged port groups, or traffic can be explicitly tagged
to identify the VLAN group to which it belongs. Untagged VLANs can be used for
small networks attached to a single switch. However, tagged VLANs should be
used for larger networks, and all the VLANs assigned to the inter-switch links.

Application Notes
APPLICATION NOTES
1. Full-duplex operation only applies to point-to-point access (such as when a
switch is attached to a workstation, server, or another switch). When the
switch is connected to a hub, both devices must operate in half-duplex
mode.
2. Avoid using flow control on a port connected to a hub unless it is actually
required to solve a problem. Otherwise back pressure jamming signals may
degrade overall performance for the segment attached to the hub.
3. As a general rule the length of fiber optic cable for a single switched link
should not exceed:
■
1000BASE-SX: 550 m (1805 ft) for multimode fiber.
■
1000BASE-LX: 10 km (6.2 miles) for single-mode fiber.
■
1000BASE-LH: 80 km (50 miles) for single-mode fiber.
■
100BASE-FX: 20 km (12 miles) for single-mode fiber.
However, power budget constraints must also be considered when calculating
the maximum cable length for your specific environment.

4 MAKING NETWORK CONNECTIONS
CONNECTING NETWORK DEVICES
This switch is designed to be connected to 10, 100, or 1000 Mbps network cards
in PCs and servers, as well as to other switches and hubs. It may also be
connected to remote devices using optional 1000BASE-SX, 1000BASE-LX,
1000BASE-LH, or 100BASE-FX SFP transceivers.
TWISTED-PAIR DEVICES
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45
connectors at both ends. Use Category 5, 5e or 6 cable for 1000BASE-T
connections, Category 5 or better for 100BASE-TX connections, and Category 3
or better for 10BASE-T connections.
POWER-OVER-ETHERNET CONNECTIONS
The switch automatically detects a PoE-compliant device by its authenticated
PoE signature and senses its required load before turning on DC power to the
port. This detection mechanism prevents damage to other network equipment
that is not PoE compliant.
N
OTE
:
Power-over-Ethernet connections work with all existing Category
3, 4, 5, 5e, or 6 network cabling, including patch cables and patchpanels, outlets, and other connecting hardware, without requiring
modification.
The switch delivers power to a device using the wire pairs in UTP or STP cable
(RJ-45 pins 1, 2, 3, and 6). The switch can provide up to 30 W of power
continuously on each of the eight RJ-45 ports. If a device tries to draw more
than 30 W from a port, an overload condition occurs and the port disables the
power.
– 49 –
C
HAPTER

Twisted-Pair Devices
The switch controls the power and data on a port independently. Power can be
requested from a device that already has a data link to the switch. Also, the
switch can supply power to a device even if the port’s data connection has been
disabled. The power on a port is continuously monitored by the switch and it will
be turned off as soon as a device connection is removed.
| Making Network Connections
CABLING GUIDELINES
The RJ-45 ports on the switch support automatic MDI/MDI-X pinout
configuration, so you can use standard straight-through twisted-pair cables to

FIBER OPTIC SFP DEVICES
An optional SFP transceiver (1000BASE-SX, 1000BASE-LX, 1000BASE-LH, or
100BASE-FX) can be used for a backbone connection between switches, or for
connecting to a high-speed server.
Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable
with an LC connector at both ends. Each multimode fiber optic port requires 50/
125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at
both ends.

ARNING
:
This switch uses lasers to transmit signals over fiber optic
cable. The lasers are compliant with the requirements of a Class 1
Laser Product and are inherently eye safe in normal operation.
However, you should never look directly at a transmit port when it is
powered on.
W
ARNING
:
When selecting a fiber SFP device, considering safety, please
make sure that it can function at a temperature that is not less than the
recommended maximum operational temperature of the product. You
must also use an approved Laser Class 1 SFP transceiver.
1. Remove and keep the LC port’s rubber plug. When not connected to a fiber
cable, the rubber plug should be replaced to protect the optics.
2. Check that the fiber terminators are clean. You can clean the cable plugs by
wiping them gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber optic cables will impair the quality
of the light transmitted through the cable and lead to degraded performance
on the port.
3. Connect one end of the cable to the LC port on the switch and the other end
to the LC port on the other device. Since LC connectors are keyed, the cable
can be attached in only one orientation.

Connectivity Rules
CONNECTIVITY RULES
When adding hubs (repeaters) to your network, please follow the connectivity
rules listed in the manuals for these products. However, note that because
switches break up the path for connected devices into separate collision
domains, you should not include the switch or connected cabling in your
calculations for cascade length involving other devices.
1000BASE-T CABLE REQUIREMENTS
All Category 5 UTP cables that are used for 100BASE-TX connections should also
work for 1000BASE-T, providing that all four wire pairs are connected. However,
it is recommended that for all critical connections, or any new cable installations,
Category 5e (enhanced Category 5) or Category 6 cable should be used. The
Category 5e and 6 specifications include test parameters that are only
recommendations for Category 5. Therefore, the first step in preparing existing
Category 5 cabling for running 1000BASE-T is a simple test of the cable
installation to be sure that it complies with the IEEE 802.3-2005 standards.

Cable Labeling and Connection Records
CABLE LABELING AND CONNECTION RECORDS
When planning a network installation, it is essential to label the opposing ends of
cables and to record where each cable is connected. Doing so will enable you to
easily locate inter-connected devices, isolate faults and change your topology
without need for unnecessary time consumption.
To best manage the physical implementations of your network, follow these
guidelines:
◆ Clearly label the opposing ends of each cable.
◆ Using your building’s floor plans, draw a map of the location of all network-
connected equipment. For each piece of equipment, identify the devices to
which it is connected.
◆ Note the length of each cable and the maximum cable length supported by
the switch ports.
◆ For ease of understanding, use a location-based key when assigning
prefixes to your cable labeling.
◆ Use sequential numbers for cables that originate from the same equipment.
◆ Differentiate between racks by naming accordingly.
◆ Label each separate piece of equipment.
◆ Display a copy of your equipment map, including keys to all abbreviations at
each equipment rack.
