There can be 24 ports operational at one time. The RJ-45 ports 1 to 4 use the same physical interface as the SFP ports 1 to 4. When an SFP is inserted into an

SFP port, the corresponding RJ-45 port is disabled. For example, if an SFP is inserted in SFP port 1, then RJ-45 port 1 is disabled. When the SFP is removed from port 1, the RJ-45 port 1 is again operational. All other RJ-45 ports function normally.

RS-232 Terminal Port

The RS-232 ASYN0/CONSOLE port is standard for the x900 series switches and SwitchBlade x908, and connects them to a management device for initial configuration. This port allows the software on the switch to be accessed from a terminal or a PC running terminal emulation software.

The ASYN0/CONSOLE port has an RJ-45 socket with an industry recognised pinout. This requires using a straight-through RJ-45 cable with an RJ-45 DB9 connector when the switch is connected to a terminal or PC. The socket is wired as a DTE and the pin layout is shown in the following table. Pins a re numbered from right to left

■ AT-9924Ts

■ x900-12XT/S x900-24X series

SwitchBlade x908

Use the management port for initial configuration and on-going management tasks. For remote access, use the default IP address, 192.168.242.242. This port is reserved for management only; the switch does not transmit frames between this port and switch ports.

On the SwitchBlade x908, the management port can also be used to create a stack resiliency link when the switch is part of a virtual chassis stack. For more information about resiliency links, see the Stacking Introduction chapter of the

AlliedWare Plus™ Operating System Software Reference.

An error message is displayed when an SFP port cannot operate at the specified speed or duplex mode.

When using SFP ports 1 to 4 on AT-9924T switches, the corresponding RJ-45 ports (1 to 4) are disabled. However, when the SFP transceiver is removed, the

RJ-45 port becomes operational again.

Inserting and removing an

SFP transceiver

The SFP transceiver must be inserted the correct way in the socket, which varies depending on whether the switch has a single or dual row of sockets.

For example, x900-48FE switches have single-row sockets, but AT-9900 series switches have a dual row. See the example of dual-row sockets for a copper SFP transceiver in the figure below. Notice the varying position of the release lever.

Warning Do not look into SFP cables or transceivers. Even disconnected fibres and connectors can emit invisible laser radiation.

■ AT-8948 x900-48FE x900-48FS

AT-9924T

AT-9924SP

Data such as releases, patches, and configurations can be stored on these cards, and files can be manipulated with the command line interface (CLI). However, release and patch files cannot be run directly from the card, but must be loaded into either NVS or on-board flash.

Important Anyone with a compliant reader can read CFlash cards so do not keep sensitive data on them.

Approved

CFlash card

The CompactFlash card approved for the x900-48FE, x900-48FS, and AT-9900 series switches is AT-CF128A-00 128 MBytes. Other cards are unlikely to work with the switch.

Inserting and removing a

CFlash card

You can insert the card into the CompactFlash slot at any time; it takes about two seconds to initialise. The following CLI message confirms that the card has been inserted:

Info (1106257): Compact flash card inserted.

The following message confirms that the card is ready to use:

Info (1106268): Compact flash card initialisation successful.

The following message means that the CFlash card is not compatible with the switch:

Info (3106300): Compact flash card initialisation unsuccessful.

Important When data is being written to or read from the card, the CF LED on the front panel of the switch is green. Do not remove the card when it is active or you will corrupt the data. Wait until the LED is off before ejecting the card.

Displaying data about a CFlash card

To display information about a CompactFlash card, including card size, file count, and serial number, insert the card and enter the command: show cflash

To display cluster ranges on a card, insert the card and enter the command: show cflash test

C613-03092-00 REV J

The following figure is an example of output from the show cflash test command when no test is running.

Clusters available for testing

Ranges:

[42645--61944]

Number of free clusters = 19300

Number of ranges = 1

Number of used clusters = 42645

Testing a CFlash card

It is important to fully test the hardware interface of the switch to the CFlash card. This test consists of reading vendor information and reading and writing to every part of the card.

To test the card, insert it in the CF slot and enter the command: enable cflash test start=startnumber end=endnumber where startnumber and endnumber are positive integers within a cluster range.

The end number must be higher than the start number. Cluster ranges are displayed in the output of the show cflash test command.

The test software reads the file allocation table and displays a list of free sectors. Sectors can be tested as single sectors or as a range. The test consists of a write/read/verify cycle.

To stop the test, use the disable cflash test command. To display test results while a test is in process, enter the show cflash test command. Also, use this command when testing is not active to display the blank clusters range on the card.

The following is example output from the show cflash test command when a test is running.

Test Progress

Starting cluster = 700

Ending cluster = 1700

Current cluster = 1185

Passed clusters number = 485

Passed sectors number = 1940

Failed clusters number = 0

Failed sectors number = 0

Used Clusters encountered = 0

Duration................ 4417 ms

Error messages are displayed when a file write fails. Failure could be because of the card being removed or an error in the card itself. For more information about these test commands and others for CFlash, see the Managing the File

System chapter in the AlliedWare

Secure Digital (SD) Card

■

■

■

■

Secure Digital cards are a memory expansion option for the following switches:

■ AT-9924Ts x900-12XT/S x900-24XT

■ x900-24XT-N x900-24XS

SwitchBlade x908

Data such as releases and configurations can be stored on SD cards, and files can be manipulated with the command line interface (CLI). On switches running the AlliedWare Plus operating system, you can boot from an SD card using the Bootloader menu. However, under normal operating conditions you cannot run release or package files directly from the SD card; they must be loaded into NVS or on-board flash.

SD cards are smaller than CompactFlash cards and have a large storage capacity. Switches accept most SD cards with various capacities up to 2 GBytes.

Be sure to verify operation before attempting to store data.

Important Do not keep sensitive data on SD cards because anyone with a compliant reader can read them.

Inserting and removing an SD card

You can insert a card into the SD slot at any time. Just push the card into the slot until you feel it latch.

When data is being written to or read from the card, the SD LED on the front panel of the switch flashes green. Do not remove the card when it is active or you will corrupt the data being read or written, and may corrupt other data on the card. Wait until the LED remains off before releasing the card. To remove the card, use a press-and-release action. Avoid touching the metal contacts.

To safeguard the data, store the card immediately in its case or somewhere away from heat, humidity, or dust. Do not store it near electrostatic, electromagnetic, magnetic or radioactive fields. If necessary, clean with a soft dry cloth.

Displaying data about an SD card

To display information about an SD card, such as card size, file count, and volume label, insert the card.

On switches running the AlliedWare operating system, use the command: show card

The following figure is an example of output from the show card command.

Volume label ......... SD_512

Files total size ..... 13367336 bytes (30 files)

Used space ........... 13434880 bytes

Free space ........... 497754112 bytes

Total space .......... 511188992 bytes

You can also use the show card command to verify whether the switch recognises the card. For more information about this command, see the

C613-03092-00 REV J

Operating System Software

Reference.

On switches running the AlliedWare Plus operating system, use the commands: awplus#show file systems awplus#dir card:/

Testing the slot

On switches running the AlliedWare operating system, you can test the SD card slot on front of the switch to verify that the hardware does the following:

■ detects the presence of a card

■

■

■ detects whether a card has been exchanged detects write-protection on a card transfers data to and from a card

The test does not write data to the card or harm existing data. To test the slot, use the command: enable test device=card type=slot

Dual In-line Memory Module (DIMM)

Synchronous DRAM (SDRAM) is provided by a single DIMM. Only DIMMs supplied by Allied Telesis have been tested and approved for use. Using unapproved DIMMs may cause unreliable operation and will invalidate the warranty for the switch .

The following SDRAM options are supported:

■ AT-8948, x900-48FE, x900-48FS, AT-9924T, and AT-9924SP switches ship with 256 MBytes of SDRAM, expandable to 512 MBytes with a DIMM.

■

■

AT-9924Ts, x900-12XT/S, x900-24XT, x900-24XT-N, and x900-24XS switches are shipped with a 512 MBytes of DDR SDRAM, no upgrades are available.

SwitchBlade x908 switches are shipped with a 512 MBytes DDR SDRAM

SODIMM. The SODIMM memory is not interchangable with the DIMM memory in other switches.

Warning Only authorised service personnel should install DIMMs. Opening the switch’s lid may cause personal injury from electric shock and could damage the switch.

Verifying DIMM installation

The switch is unlikely to boot unless the DIMM is correctly installed. You will not be able to issue any diagnostic commands, and will have to rely solely on

LED fault codes.

If the switch boots up but you suspect the DIMM is malfunctioning, display

system information by using the show system command. See “Verifying installation” on page 40

for output.

The size of SDRAM is in the memory section of the output. If the SDRAM size is less than the size of DIMM that has been installed, then the switch has not detected the DIMM. The most likely cause is that the DIMM connector is not correctly plugged into the slot.

Record the switch’s serial number and revision details for later reference. If you have questions or problems with the DIMM at any time, contact your authorised Allied Telesis distributor or reseller and supply these serial numbers.

IPv6 Accelerator Card

An optional AT-ACC01 network processor accelerator card accelerates IPv6 unicast and multicast routing in hardware on AT-8948 switches. For full functionality, 512 MBytes SDRAM must be installed in the switch.

How the card works

When the switch receives an IPv6 packet to route, the packet is sent to the network processor accelerator card. The card processes the packet and sends it out the correct port with appropriate alterations to the packet. Other IPv6 functions are passed to software, such as routing protocol control packets, encryption, authentication, and hop-by-hop headers.

C613-03092-00 REV J


No configuration is necessary for the accelerator card to function; the card is enabled at installation. If you disable the card (using software), the switch handles IPv6 routing in the software.

Use the hardware filter and QoS commands to enable Quality of Service (QoS) functionality on the accelerator card. For information about QoS functionality and hardware filters, see the Quality of Service and Switching chapters in the

Software Reference.

Warning Only authorised service personnel should install a network processor accelerator card. Opening the switch’s lid may cause personal injury from electric shock, could damage the switch, and will invalidate the product warranty.

C613-03092-00 REV J

Verifying installation

To confirm that the network processor accelerator card is installed and operating correctly, check that the switch has recognised it. Turn on the switch and enter the show system command to display system information. The following figure is an example of output from the show system command for the AT-8948 model.

The first section of the output shows information about boards installed in the switch. There are details about the switch base card, the accelerator card if installed, and the type of power supply unit or fan-only module. Both the part names and serial numbers of the base card and accelerator card are displayed.

Record the details of the base card and the network processor accelerator card for later reference. If you have questions or problems with the network

C613-03092-00 REV J

Hardware Reference 41 processor accelerator card at any time, contact your authorised Allied Telesis distributor or reseller and supply the serial numbers for them.

If there is no entry for the accelerator card, then the switch’s boot process has not detected the card. The most likely cause is that the card is incorrectly plugged into the slot on the switch’s base board.

Displaying information about the card

To display information about the status and memory of a network processor accelerator card on AT-8948 switch, use the show switch accelerator command.

Test Facility

The test facility is a hardware test tool in the AlliedWare operating system. Its primary function is to validate that there are no hardware problems after installation of the switch or expansion options. You can also use it as a troubleshooting tool, but it is just one of many such tools. You could consider the test facility to be a specialised interface module, such as PPP or Frame

Relay, where the interfaces under test are dedicated to the test facility.

Before you use the test facility, disable configurations by using the set configuration=none command, and restart or reboot the switch. For more information about the test facility, see the Test Facility chapter in the

AlliedWare

Use a terminal cable to connect a terminal to the RS-232 port (ASYN0/

CONSOLE) on the switch. For more information on terminal cables, see

“RS-232 Terminal and Modem Cables” on page 30 .

Set the terminal communication parameters as follows:

• Baud rate: 9600

• Data bits: 8

• Parity: None

• Stop bits: 1

• Flow control: Hardware

For more information, see

“Using Windows Terminal and HyperTerminal” on page 44 .

2.

Restart the switch.

To restart the switch, use a small diameter pin to press the recessed Reset button on the front panel of the switch. You can also log in at the terminal and enter the command: restart reboot

How to log in is described in the Installation and Safety Guide.

Troubleshooting

■

■

This section provides information on how to troubleshoot the x900 series switch and SwitchBlade x908 to resolve the following basic problems:

■

L/A LED on a port is off

Power LED is off

Fault LED is on

What to check first

■ Check power cord connections.

■

■

■

■

■

Check that the power supply voltage is stable.

Check that the correct data cables are used and that their connections are secure.

Make sure that other network devices work properly.

Check that the latest software release is loaded. The Software Reference describes how to obtain the latest software release.

• On switches running the AlliedWare operating system, use the show install command.

• On switches running the AlliedWare Plus operating system, use the show version command.

If the switch malfunctions, reboot it using one of the following methods:

• use a small diameter pin to operate the recessed Reset button on the switch’s front panel

• shut down and restart the switch at the main power source (AC models) or use the Run/Standby switch on the PSU (DC models).

• On switches running the AlliedWare operating system, use the restart reboot command.

• On switches running the AlliedWare Plus operating system, use the reload command.

L/A LED on a port is off

■

■

■

■

If the Link/Activity LED is off, it may indicate the following: a loose data cable the device at the other end of the connection does not work properly or is turned off

■ the data cable is not wired correctly the network administrator has manually disabled the port through the software the port’s selected transmission mode does not match that of the attached device

Follow these suggestions to resolve the problem:

1.

Make sure the data cable connections are secure.

2.

Make sure the device at the other end of the connection is powered on and works properly.

3.

Check that the data cable is wired correctly.

4.

If you can, log in and check the port status. How to log in is described in the x900 Series Switch and SwitchBlade

5.

If the port is enabled, make sure the transmission speed matches that of the connected device (autonegotiating, full or half-duplex).

6.

If the port is disabled, someone disabled it with the software. Find out why before you enable it.

Power LED is off

If the power LED is off, it may indicate the following:

■

■

■ a loose power cord a power supply failure a FOM is installed in that bay


1.

Check that the power cord connections are secure.

2.

Check that all switches and circuit protection devices are in the “on” position.

3.

Ensure that the supply voltage is within the operational range. See “Power

Supply Units (PSUs) and Fans” on page 35 .

Fault LED is on

If the fault LED is on, it may indicate the following:

■ there is a problem with the switch

■

■ the switch or management software is malfunctioning a hardware fault is preventing switch startup


1.

Read the descriptions of LED flashing sequences for explanations of what to do (see

“Switch LEDs” on page 15 ).

2.

Reset the switch. Use a small diameter pin to press the recessed reset button on the front panel of the switch.

3.

If you were attempting to download software or manage the switch over the
