The port is operating in Tull duplex mode. The port is operating in half duplex mode.

Collisions are occurring.

PSU 1 is installed and supplying power to the switch. The voltage output is within specification. PSU 1 is in the right bay when facing the rear of the switch.

One of the following:

e PSU 1 is installed in the switch, and either a fan has failed or the PSU has exceeded Its recommended temperature threshold of 75° C (167° F).

e AFOM is installed in the switch and a fan has failed. e The bay is empty.

A FOM is installed and operating at an acceptable speed.

For AT-9924T and AT-9924SP models, this LED is always off because a FOM is not required.

PSU 2 is installed and supplying power to the switch. The voltage output is within specification. PSU 2 is in the left bay when facing the rear of the switch.

One of the following:

Using AT-TFIP Server

This section explains how to access and use the AT-TFIP Server. You can transfer configuration files as well as download software upgrades with AT-TFIP Server.

1. If AT-TFIP Server has not been installed, install it from the Documentation and Tools CD-ROM.

Select AT-TFTP Server from the Start > Programs > Allied Telesyn > AT-TFIP Server menu.

2. To set preferences for the AT-TFIP Server, select Options from the File menu to display the Set Preferences dialog box shown below.

Set Preferences xi

A default directory for the TFTP daemon to read and write files from can be specified. File requests without a directory specification will use this directory.

Default file transfer directory c:\upload

To aid secunty. file access can be restricted to one directory. Restrict to directory

c:\upload The TFTP daemon can be zet to read only or read and write. In read only mode, file write requests to pour system will be rejected.

IY Read Only l Read Write

To see extra program diagnostic messages click the control below on

Diagnotic Messages

The "Default file transfer directory" field specifies the directory that AT-TFIP Server reads from or writes to for file requests that do not include a directory specification.

Enter a path name in the "Restrict to directory" field to prevent unauthorised access to private directories. AI-TFIP Server uses the specified directory even when file requests contain references to other directories.

To prevent files from being written to the PC, click the Read only checkbox.

To use the PC to archive scripts created using the switch's create config command, click the Read Write checkbox.

Click the OK button when you finish.

3. To load a file from AT-TFIP Server to the switch, type the following command on a terminal connected to the RS-232 Terminal Port (ASYNO):

load method=tftp file=filename server=ipadd dest=flash

where filename is the name of the file to download and ipadd is the IP address of the PC running AT-TFIP Server.

4. To save a TFIP Server log, select Save As from the File menu. TFTP requests are logged to the AT-TFIP Server main window.

Using Windows Terminal and HyperTerminal

You can use a PC running terminal emulation software as the manager console, instead of a terminal. There are many terminal emulation applications available for PCs, but the most readily available are the Terminal and HyperTerminal applications included in Microsoft Windows 98, 2000, and

XP Professional. In standard Windows installations, HyperTerminal is available from the Communications submenu.

The key to successful use of terminal emulation software with the switch is to configure the software and switch with matching communications parameters. The following procedure can be applied to most terminal emulation programs. Dialog boxes in the procedure are from Windows 2000 and XP Professional.

To configure Windows HyperTerminal for 2000 and XP Professional

1. Start the program in Windows by doing one of the following: e Select Programs > Accessories > Communications > HyperTerminal. e Double-click the Hypertrm.exe icon.

2. Inthe Connection Description dialog box: e Enter a name for the connection, such as AT99001.

How the Switch Starts Up

When the switch starts up following a power cycle or an operator-initiated reboot (using the reset button or restart command), it performs a series of tests and sends messages to the terminal or PC connected to the ASYNO port. After the switch successfully starts, a prompt is displayed for you to log in. Refer to the Installation and Safety Guide for basic login instructions or to the Getting Started chapter in the Software Reference.

AT-8900 and AT-9900 Switches

When an AT-8900 or AT-9900 switch starts, it performs the following operations.

Stage This happens... Done by... 1 Self-tests run that check basic operations. Boot ROM 2 A prompt is displayed briefly to allow a user-override. Users can Boot ROM

change the startup process by pressing special keys (see Overrides). If they enter nothing, the process continues.

devices connected to it are sending traffic.

The switch pauses briefly during routine startup messages to display the following prompt:

AT-9900s Switches

This section explains how AT-9900s switches start initially, including error messages. The following types of software play key roles during startup.

Software Description

Base Product software that is typically the “preferred” base package installed. It constitutes a feature set—similar to a "release”—and runs the switch. A software licence must be enabled for specific base packages.

Fallback A small subset of the base package that runs when the base package Is unavailable. It can download and install a base package, modify configuration scripts, and monitor the system.

Bootloader Software that runs the switch when it first powers up. It performs basic initialisation, provides a basic interface for hardware diagnostics, and executes either the product or fallback software.

When the switch starts, it performs the following operations.

Stage This happens... Done by... 1 Self-tests run that check basic operations. Bootloader 2 A prompt is displayed briefly to allow a user-override. Users Bootloader

can change the startup process by pressing special keys (see Overrides). If they enter nothing, the process continues.

3 Product software or fallback software is executed, depending Bootloader on what the user installed. 4 Hardware boards and software components are initialised. Base or Fallback 5 The startup configuration script that the user specified is Base or Fallback executed. 6 Startup is complete and the switch starts switching traffic if Base

devices connected to it are sending traffic.

The AT-9900s switch pauses briefly during startup messages to display the following prompt:

Boot fallback software (Y)? If you do nothing, the installed base package loads along with a preconfigured

startup script. For troubleshooting, change the process by using the following keys.

Pressing this key... Forces the switch to...

Y Load the fallback software instead of the base package, and skip the startup configuration script.

S (skip) Load the base package and skip the startup configuration script.

Ctrl+B Display a bootloader prompt. To upgrade a bootloader file, load the

new .bin Tile into the file system, and enter the command: copy filename.bin bootloader

For information about the load command, see the Managing Configuration Files and Software Versions chapter in the Software Reference.

Ctrl+D Enter diagnostics mode. For more information, see “Diagnostics” on page 41.
