Chapter 1

Hardware Description

This chapter describes the hardware features of the following
products:

" The base switch models: AT-8118, AT-8124XL, and AT-8126XL

" The uplink options, also called media dependent adapters

(MDAs): AT-A10, AT-A11, AT-A20, and AT-A21

The Base Switch Models

The AT-8118, AT-8124XL, and AT-8126XL switches are standalone
managed Fast Ethernet switches that provide 16 or 24 10Base-T/
100Base-TX station ports. The AT-8118 and AT-8126XL additionally
provide uplink options of up to two 100Base-TX or 100Base-FX (SC,
MT-RJ or VF-45) ports for backbone connectivity

They are primarily intended for connections to the desktop as well as
workgroup applications. The AT-8118 and AT-8126XL, when
populated with optional uplink ports, implement direct high-speed
server and backbone connections. Half- or full-duplex capability on
all ports eliminate collisions and provide up to 200 Mbps of
bandwidth per port to servers, routers, and other switches. The auto­negotiating ports allow connectivity between devices operating at
10 Mbps and 100 Mbps speeds.

With built-in management, the switches provide seamless
management capability such as SNMP and web-based management.

Switching Modes

AT-8118, AT-8124XL, and AT-8126XL Installation Guide

Each switch port has the following user-selectable switching modes:

" Store-and-forward (default)

" Fragment-free cut-through for 100 Mbps ports

Network administrators can configure the sending port with the
appropriate switching mode to optimize performance and enable
full-error checking. The modes reduce network bottlenecks by
offering low latency wire rate switching for the port.

With the store and forward method, the port waits to receive an
entire packet before forwarding it to its destination. This method
ensures that packets being forwarded are free of errors. The store
and forward mode (default) is automatic when data is exchanged
between 10Base-T and 100Base-TX ports.

With the cut-through method (for 100 Mbps ports only), the port
starts to forward the packet once the packet has exceeded the
smallest size (64 bytes), therefore filtering fragment frames or runts
(frames less than 64 bytes). This method provides low latency for
forwarding frames and also provides some network error protection.

Hardware Description

Physical Description

The switches have the following major front panel components:

" 16 or 24 Ethernet 10Base-T/100Base-TX unshielded twisted

Connecting Devices to the Switch

The switch supports connectivity with DTEs such as workstations and
servers, and also DCEs such as hubs, routers, and other switches. The
switch supports devices that operate at fixed speeds, 10 Mbps or 100
Mbps, or auto-negotiating, 10/100 Mbps.

When connecting devices, consider the following:

" For dedicated 10Base-T connections, use Category 3, 4, or 5

Unshielded Twisted Pair (UTP) cables with maximum length of
330 ft (100 m).

" For 10Base-T/100Base-TX or dedicated 100Base-TX

connections, use Category 5 UTP cables with maximum length
of 330 ft (100 m).

" For 100Base-FX fiber connections, use 50/125- or 62.5/125-

micron multimode fiber cables with maximum length of
1,351 ft (412 m) for half-duplex or 1.25 mi (2 km) for full­duplex.

AT-8118, AT-8124XL, and AT-8126XL Installation Guide

" Use straight-through cables to connect to workstations and

servers.

" Use crossover cables to connect to hubs, routers, and other

switches.

Troubleshooting

How the Switch Reports Problems

The switch detects and processes errors as follows:

" The LEDs indicate problems with the port and power.

Table 3-1 describes the switch LEDs.

" In a TCP/IP environment, if you have configured the software

correctly, the management software triggers an SNMP trap
message. As a result, the software then sends traps to alert the
network manager when a trigger occurs. This type of software
configuration allows the network administrator to pro­actively monitor their network.

Table 3-1 lists and describes the switch LEDs.
