Product Description
Hardware Feature Description
The following sections describe hardware features of the AT-GS916 and
AT-GS924 Gigabit Ethernet switches:
System and Port LEDs
Twisted Pair Ports
AC Power Connector
Twisted Pair
Ports
The AT-GS916 Gigabit Ethernet switch features 16 twisted pair ports, and
the AT-GS924 Gigabit Ethernet switch features 24 twisted pair ports.
Type of Connector
The twisted pair ports feature 8-pin RJ-45 connectors. (For the port
pinouts, refer to ”RJ-45 Twisted Pair Port Pinouts” on page 37.
Speed
The ports are 10Base-T, 100Base-TX, and 1000Base-T compliant and are
capable of 10 megabits per second (Mbps), 100 Mbps, and 1000 Mbps
speeds. The ports are IEEE 802.3u Auto-Negotiation compliant. With
Auto-Negotiation, the switch automatically matches the highest
possible common speed between each switch port and each end-node.
For example, if an end-node is capable of only 10 Mbps, the switch sets
the port connected to the end-node to 10 Mbps.
Duplex Mode
Each twisted pair port on the switch can operate in either half- or full
duplex mode. The twisted pair ports are IEEE 802.3u-compliant and will
Auto-Negotiate the duplex mode setting.
Note
In order for the switch to set the duplex mode for each port
correctly, the end-nodes that you connect to the switch ports
should also use Auto-Negotiation. Otherwise, a duplex mode
mismatch can occur, affecting network performance. For further
information, refer to ”Duplex Mode” on page 16.
12
Maximum Distance
Each twisted pair port has a maximum operating distance of 100 m
(328 feet).
Type of Cabling
For 10 Mbps operation, Category 3 or better 100 ohm shielded or
unshielded twisted pair cabling is required. For 100 or 1000 Mbps
operation, Category 5 and Enhanced Category 5 (5E) 100 ohm shielded
or unshielded twisted pair cabling is required.

Auto MDI/MDI-X
All of the twisted pair ports on the switch are auto-MDI and IEEE
802.3ab-compatible. When a port's speed and duplex mode are set
through Auto-Negotiation, the port uses the auto-MDI feature to
automatically configure itself as MDI or MDI-X when connected to an
end-node. Consequently, you can use either a straight-through or
crossover twisted pair cable when connecting any network device to a
port.
LEDs The system and port LEDs on the front panel of the AT-GS916 and AT-
GS924 switches display the switch and its port status information. Each
port has four LEDs.

A Few Ethernet Switching Basics
An Ethernet switch interconnects network devices, such as workstations,
printers, routers, and other Ethernet switches, so that they can
communicate with each other by sending and receiving Ethernet
frames.
AT-GS916 and AT-GS924 Gigabit Ethernet Switches Installation Guide
MAC Address
Table
Every hardware device on your network has a unique MAC address. This
address is assigned to the device by the device’s manufacturer. For
example, when you install a Network Interface Card (NIC) in a computer
so that you can connect it to the network, the NIC already has a MAC
address assigned to it by its manufacturer.
The AT-GS916 and AT-GS924 Gigabit Ethernet switches can contain up
to 8,000 entries on its MAC address table. The switch uses the table to
store the MAC addresses of the network end-nodes connected to the
ports, along with the port number on which each address was learned.
A switch learns the MAC addresses of the end-nodes by examining the
source address of each packet received on a port. It adds the address
and port on which the packet was received to the MAC table if the
address had not already been entered in the table. The result is a table
that contains all the MAC addresses of the devices that are connected to
the switch’s ports, and the port number where each address was
learned.
When the switch receives a packet, it also examines the destination
address and, by referring to its MAC address table, determines the port
on which the destination end-node is connected. It then forwards the
packet to the appropriate port and on to the end-node. This increases
network bandwidth by limiting each frame to the appropriate port when
the intended end-node is located, freeing the other switch ports for
receiving and transmitting data.
If the switch receives a packet with a destination address that is not in
the MAC address table, it floods the packet to all the ports on the switch.
If the ports have been grouped into virtual LANs, the switch floods the
packet only to those ports which belong to the same VLAN as the port
on which the packet was received. This prevents packets from being
forwarded into inappropriate LAN segments, increasing network
security. When the destination end-node responds, the switch adds its
MAC address and port number to the table.
15
Product Description
If the switch receives a packet with a destination address that is on the
same port on which the packet was received, it discards the packet
without forwarding it on to any port. Since both the source end-node
and the destination end-node for the packet are located on the same
port on the switch, there is no reason for the switch to forward the
packet.
Duplex Mode Duplex mode refers to how an end-node receives and transmits data. If
an end-node can receive or transmit data, but not both simultaneously,
the end-node is operating in what is referred to as half-duplex mode. If
an end-node can both receive and transmit data simultaneously, the
end-node is said to be operating in full-duplex mode. Naturally, an endnode capable of operating in full-duplex can handle data much faster
than an end-node that can only operate in half-duplex mode.
The twisted pair ports on the AT-GS916 and AT-GS924 switches can
operate in half- or full-duplex mode for 10/100 Mbps and full-duplex for
1000 Mbps. They are IEEE 802.3u-compliant and use Auto-Negotiation to
set the duplex mode setting for you automatically.
Store and
Forward
Backpressure
and Flow
Control
An AT-GS916 or AT-GS924 switch uses store and forward as the method
for receiving and transmitting frames. When a Ethernet frame is received
on a switch port, the switch does not retransmit the frame out the
destination port until it has received the entire frame and stored the
frame in a port buffer. It then examines the frame to determine if it is a
valid frame. Invalid frames, such as fragments or runts, are discarded by
the switch. This insures that only valid frames are transmitted out the
switch ports and that damaged frames are not propagated on your
network.
To maintain the orderly movement of data between the end-nodes, an
Ethernet switch may periodically need to signal an end-node to stop
sending data. This can occur under several circumstances. For example,
if two end-nodes are operating at different speeds, the switch, while
transferring data between the end-nodes, might need to instruct the
faster end-node to stop transmitting data to allow the slower end-node
to catch up. An example of this would be when a server operating at 100
Mbps is sending data to a workstation operating at only 10 Mbps.
How a switch signals an end-node to stop transmitting data differs
depending on the duplex mode of the end-node and switch port. A
twisted pair port operating in half-duplex mode stops an end-node from
transmitting data by forcing a collision. A collision on an Ethernet
network occurs when two end-nodes attempt to transmit data using the
same data link at the same time. A collision causes an end-node to stop
sending data, wait for a brief period of time, and then retransmit the
same data. Once the switch is ready to receive data again, the switch
stops forcing collisions. This is referred to as backpressure.
16
AT-GS916 and AT-GS924 Gigabit Ethernet Switches Installation Guide
A port operating in full-duplex mode uses PAUSE frames, as specified in
the IEEE 802.3x standard, to stop the transmission of data from an endnode. Whenever the switch wants an end-node to stop transmitting
data, it issues this frame. The frame instructs the end-node to cease
transmission for a period of time specified within the frame. The switch
continues to issue PAUSE frames until it is ready again to receive data
from the end-node. This is referred to as flow control.
17
Product Description
Network Topologies
This section illustrates two network topologies that you can create with
the AT-GS916 Gigabit Ethernet switch: a power workgroup and
collapsed backbone. Both types of topologies are described below.
Power
Workgroup
Topology
The topology shown in Figure 4 is commonly referred to as a power
workgroup topology. Each workstation or end-node is connected
directly to a port on the switch. Each end-node has a dedicated data link
to the switch for best performance and reliability. The devices can
operate at 10 Mbps, 100 Mbps or 1000 Mbps.

Collapsed Backbone
In the topology illustrated in Figure 5, an AT-GS916 switch connects Fast
Ethernet switches that have Gigabit Ethernet uplinks. This type of
topology is often referred to as a collapsed backbone topology. The
switch functions as the focal point of the network and transfers an
Ethernet frame between the Fast Ethernet switches only when the
destination end-node for the frame is on a different switch than the endnode that originated the frame. This reduces the amount of unnecessary
data traffic in each workgroup, freeing up bandwidth and improving
network performance.

Installation
Selecting a Site for the Switch
Observe the following requirements when choosing a site for your
switch:
If you plan to install the switch in an equipment rack, ensure that
the rack is safely secured and that it will not tip over. Devices in a
rack should be installed starting at the bottom, with the heavier
devices near the bottom of the rack.
If you are installing the switch on a table, ensure that the table is
level and secure.
The power outlet for the switch should be located near the unit
and should be easily accessible.
The site should provide for easy access to the ports on the front of
the switch. This will make it easy for you to connect and
disconnect cables, as well as view the switch’s LEDs.
To allow proper cooling of the switch, air flow around the unit and
through its vents on the side and rear should not be restricted.
Do not place objects on top of the switch.
Do not expose the switch to moisture or water.
Ensure that the site is a dust-free environment.
You should use dedicated power circuits or power conditioners to
supply reliable electrical power to the network devices.
