Model Naming Conventions
The letters and numbers in the model names identify the hardware
features of the switches. The naming conventions for the twisted pair
8100S Series switches are identified in Figure 8.
Figure 8. Model Naming Conventions for the Twisted Pair 8100S Series
The conventions are defined in Table 4.
Table 4. Model Naming Conventions for the Twisted Pair 8100L and
Switches
8100S Series Switches
Convention Definition
1 This is the product name.
2 The letter “S” indicates that the model is stackable.
The letter “L” indicates that the model is not stackable.
(The non-stackable switches are not described in this
manual. For installation instructions, refer to the
Stand-alone Switch Installation Guide for 8100L and
8100S Series Switches.)
3 This is the number of 10/100Base-TX ports.
4 The letters “POE” indicate support for Power over
Ethernet.
The letter “C” in the AT-8100S/24C model name denotes that the unit,
which has just one power supply, is smaller and more compact than the
other models.
The model naming conventions for the fiber optic 8100S Series switches
are identified in Figure 9.

AT-8100S/16F8-SC and AT-8100S/16F8-LC
Switches.

Chapter 1: Overview
Note
10/100Base-TX Twisted Pair Ports
The switches have 8 or 24 10/100Base-TX ports.
Speed The ports can operate at either 10 or 100 Mbps. The speeds may be set
manually using the management software or automatically with AutoNegotiation (IEEE 802.3u), the default setting.
Duplex Mode The twisted pair ports can operate in either half- or full-duplex mode. The
duplex mode determines the manner in which a port transmits data. A port
set to half-duplex can either transmit or receive data at one time, while a
port operating in full-duplex can transmit and receive data at the same
time. The best network performance is achieved with the full-duplex
setting, but not all network equipment is designed to support that duplex
mode.
The duplex modes, like port speeds, may be set manually using the
management software or automatically with Auto-Negotiation (IEEE
802.3u), the default setting.
Wiring
Configuration
The speed and duplex mode settings of a port may be set independently
of each other. For example, a port may be configured such that its speed
is set manually while its duplex mode is established through AutoNegotiation.
A switch port that is connected to a network device that does not
support Auto-Negotiation and has a fixed duplex mode of full-duplex
should not set its duplex mode with Auto-Negotiation. A duplexmode mismatch in which a switch port and a network device operate
at different duplex modes, may occur. The duplex modes of switch
ports that are connected to network devices that do not support
Auto-Negotiation should be set manually through the management
software.
The wiring configuration of a port can be MDI or MDI-X. The wiring
configurations of a switch port and a network device connected with
straight-through twisted pair cabling have to be opposite, such that one
device is using MDI and the other MDI-X. For instance, a switch port has
to be set to MDI-X if it is connected to a network device set to MDI.
You may set the wiring configurations of the ports manually or let the
switch configure them automatically with auto-MDI/MDI-X (IEEE 802.3abcompliant). This feature enables the switch to negotiate with network
devices to establish the proper settings, so that the ports on the devices
are using different wiring configurations.
