SwitchBlade Overview

This section provides an introduction to the SwitchBlade’s hardware and operational characteristics.

Key Hardware Components

SwitchBlade switches are based on a modular design. Several key components (or modules) are required before the switch will function, these are listed below:

• Chassis - Contains and interconnects switch components.

• Power Supply Units (PSU) - Provides a number of low voltage DC

supplies for the switches’ internal circuitry. Users may specify either AC or DC power supplies. For some switch configurations two PSUs may be necessary, plus an additional PSU where N+1 redundancy is required.

• Fan tray - Provides cooling fans for the switch and line cards.

• Line cards - Provides layer 2/3 switching and the physical interfaces for

connecting the cables/fibre. Additional line cards may be added to provide more ports and more port types than can be supplied by a single card.

• Switch controller - Provides advanced switching operations and

configuration ports for the switch. An additional switch controller may be added to increase speed and provide switch processing redundancy.

The SwitchBlade’s modular design delivers both reliability and scalability. Dual switch controllers and multiple power supply units provide the redundancy needed to ensure continuous network service. Line cards incorporating Ethernet, fast Ethernet, and gigabit Ethernet (with both copper and fibre interface options) are supported to meet the needs of rapidly evolving networks.

Chassis Models

C613-03060-00 REV H

SwitchBlade chassis are available in two fundamental types: an eight slot chassis (AT-SB4108), and a four slot chassis (AT-SB4104).

The eight slot chassis (AT-SB4108) provides space for the following units:

• two switch controller cards

• eight line cards

• three PSUs

• one AT-SB4151 fan tray

• one cable manager with four loops

8 SwitchBlade 4000 Series Switch

The four slot chassis (AT-SB4104) provides space for the following units:

• two switch controller cards (or one switch controller and one

bandwidth expander)

•four line cards

•two PSUs

• one AT-SB4151 fan tray

Both chassis types are available in either AC or DC power supply.

The eight slot AC chassis models can be supplied with either dual or triple power feeds. These models are listed below:

• AT-SB108-00 triple AC feed

• AT-SB108-60 dual AC feed

All the four slot and DC chassis models are supplied with dual power feeds.

All SwitchBlade controller cards and line cards are compatible with both the four and eight slot chassis types. For example, an AT-SB4211 switch controller can be used in both the eight slot chassis and the four slot chassis.

Eight Slot Triple Feed

Models

Eight Slot Dual Feed

Models

The bandwidth expander (AT-SB4215) can be used only in switch controller bay B of the four slot chassis.

Fan trays can be used only in their own particular chassis type. The AT-SB4151 fan tray can only be used in the four slot chassis, while the AT-SB4152 fan tray can only be used in the eight slot chassis.

Power Feed Options

The eight slot AC chassis is available with either triple AC power feeds or dual AC power feeds. The eight slot DC chassis is only available with dual DC power feeds.

In these models each power feed connects only to its own associated power supply. Therefore, if power to a particular feed is lost, then the PSU associated with that feed will cease to operate. If the chassis contains three PSUs then power will continue be drawn from the remaining two PSUs. However, with only two PSUs installed, a disconnected power feed will result in power only being supplied from the single remaining PSU, which, depending on configuration, may - or may not - be sufficient to meet the chassis’ full power requirements.

In these models, two feeds supply power to the chassis, which can contain up to three PSUs. To provide power feed redundancy, a relay is used to enable each of the two feeds to supply power to both its own PSU, plus the PSU located in the centre bay, as shown.

Dual Power Feed Connections

In the default mode, power feed1 supplies power to PSU 1 and PSU 2, and power feed 2 supplies power only to PSU 3. Power feed redundancy is provided as follows:

■ If power is disconnected from power feed 2, then PSU 1 and PSU 2 will

continue to supply power from power feed 1.

■ If power is disconnected from feed 1, then the relay will switch to

disconnect PSU 2 from power feed 1 and reconnect it to power feed 2. DC power will then be provided via PSU 2 and PSU 3.

Power Supplies

The SwitchBlade chassis and power supplies offer a number of options such as hot swapping that provide varying degrees of resiliency and recovery.

See “Power Feed Options” on page 8, “AT-SB4161 & 2 SwitchBlade Power Supply Units” on page 19, and “How Many PSUs do You Need?” on page 33.

C613-03060-00 REV H

10 SwitchBlade 4000 Series Switch

Switching Performance and Characteristics

The SwitchBlade architecture is based on a non-blocking wire-speed Layer 2 and 3 switching fabric. Layer 3 switching is performed by line cards as well as switch controllers. As with other Allied Telesis Layer 3 switches, the SwitchBlade includes full multiprotocol routing capabilities.

Layer 3 switching performance is determined by the number of switch controllers and line cards that are installed. If two switch controllers are installed, each line card operates at maximum bandwidth. This provides switching capacity of 192 Gbps for the 4 slot chassis, and 384 Gbps for the 8 slot chassis. The 4 slot chassis can also achieve maximum bandwidth when one switch controller and a bandwidth expander (AT-SB4215) are installed.

Master Switch Controller and Slave Switch Controller Interactions

The first switch controller to be installed in a chassis should be located in switch controller bay A. This controller acts as the master switch controller, performing all table updates and packet exception processing. Its “Master” LED lights to confirm that it is the master switch controller.

When a second switch controller is installed, it is automatically designated slave status. In this case the master still performs all table updates and packet exception processing, but the switching load is shared between the two controllers, while the slave maintains copies of the master’s routing tables.

Installing two switch controllers enables processing redundancy. If a switch controller fails, or is removed, then the other controller assumes master status and continues all processing operations. If the only operational controller is in Bay B, then this will retain master status until an operational controller is inserted in Bay A and a system reset or restart occurs.

Hot Swapping

Hot swapping is the replacement of a component (such as a line card) while the switch is powered up. The following SwitchBlade components can be hot swapped:

• Power supply units (PSUs). The switch will continue to operate as long

as sufficient functional PSUs remain in place to meet the switch’s power demand. “How Many PSUs do You Need?” on page 33 provides more information on switch configurations and their power demands.

Note that only certain power supplies are fully hot swapable and that this ability relates to the PSU being inserted, not the one being removed. The following PSUs are fully hot swapable: AT-SB4162-V2 AC PSU, and AT-SB4162-80 DC PSU.

• Fan trays. Although the switch can operate for short periods without a

fan tray, such as while exchanging fan trays, it should not left running for longer periods without a fan tray operating.

• Switch controllers. The switch will continue to operate as long as at least

one functional switch controller (master or slave) remains in place, although a brief pause in switching and routing may occur. Packets passing through the switch during a switch-controller hot swap will be lost.

C613-03060-00 REV H

Hardware Reference 11

• Line cards. Equivalent cards can be exchanged without having to

reconfigure the switch. For example, if an AT-SB-4311 line card is removed and replaced with a new AT-SB-4311 (in the same bay), the new card will use the original card’s configuration (as long as the switch is not restarted before the new card is installed).

The next section describes the configuration effects of hot-swapping a line card.

Hot-swapping a Line Card

Line cards can be hot swapped without requiring without requiring any notification to the switch. The SwitchBlade detects that a card is being removed and sets itself to a safe state. Insertion of any card into the SwitchBlade is detected and initialised automatically.

Hot-swapping line cards has the following scenarios:

■ A bay was previously empty and a card is being hot swapped in.

The line card powers up with no configuration, adding all of its ports to the default VLAN.

■ A bay was previously occupied and a different card type is being hot

swapped in. The line card powers up and is configured exactly as if the bay were previously empty. Previous interfaces marked as swapped out for this bay are replaced with new card interfaces.

■ A bay was previously occupied and the same card type is being hot

swapped in. The previous VLAN configuration for the card is restored to its previous condition and previous trunking settings are restored. Interfaces registered against this card are marked up or down as appropriate. Switch table entries are restored except for entries that are timed to allow natural expiry (for example, MAC and IP multicast).

■ A line card is being removed from a bay.

Interfaces registered against this card are marked as swapped out. All other modules treat these interfaces as being present but no longer active.

Before hot-swapping a line card out of the switch, we recommend that you save the current configuration by using the command:

create config

Reconfiguring During Hot swap

After a line card has been hot swapped out, the switch can be reconfigured before the removed line card is returned. The new configuration can be saved by using the command:

C613-03060-00 REV H

create config

References to the missing ports are retained in the switch’s memory. The configuration appears the same as if the line card had not been removed. To display it, use the command:

show config dynamic

When the line card is hot swapped in again, whether its original configuration is restored depends on the following factors:

12 SwitchBlade 4000 Series Switch

■ Whether a power cycle occurred between the create config command and

the line card being replaced, and

■ If a power cycle did occur, whether another create config command has

been entered.

The process flow is shown in Figure 1-1 on page 12.

unless you want t o delete t he original c onfiguration of the

previously-hotswapped card.

C613-03060-00 REV H

Hardware Reference 13

The most desirable situation is to avoid a power cycle before replacing the line card. However, if a power cycle does occur, the line card’s original configuration is saved by the switch and can be displayed by using the command:

show config dynamic

Look for “Swapped out” headings in the Switch (post-VLAN and pre-VLAN), STP, VLAN, QOS, and GARP sections. To restore the line card’s original configuration, hot swap the line card back in and restart the switch by using one of the commands:

restart switch restart reboot

Do not enter the create config command before performing this restart unless you want to delete the original configuration of the line card that you hot swapped back in.

When a configuration file is manually edited, port ranges can only be entered as a single term when the range does not span across line cards. For example, a correct entry in a configuration file is:

add vlan=2 port=1.1-1.8,5.1-5.7

An incorrect entry is:

add vlan=2 port=1.1-5.7

If a range that spans several line cards is specified as a single term, the switch is unable to determine at start-up whether any line cards within the range have been removed.

This limitation does not apply when a range of ports is entered into a command on the command line interface because the switch correctly splits the range when performing a create config command.

Examples

The following examples describe possible scenarios where slots 1 and 2 are occupied by 8-port line cards and Line Card 1 is hot swapped out.

1. Line Card 1 is removed after being configured via a boot configuration. A line card of the same type is replaced in the slot.

The second line card is reconfigured to behave exactly as the original line card. All switch table entries are restored except for entries timed to allow natural expiry (for example, MAC and IP multicast). Changes to hardware such as RDRAM or silicon version are used to the greatest extent possible (for example, performance may change but functionality remains the same).

C613-03060-00 REV H

2. Line Card 1 is removed after being configured via a boot configuration. A line card of a different type is replaced in the slot.

This situation is the same as if a line card were inserted into a system that was previously unoccupied. The line card is initialised without configuration. No configuration from the current configuration file is applied.

3. Line Card 1 is removed after being configured via a boot configuration and the slot is left empty.

14 SwitchBlade 4000 Series Switch

The switch’s configuration maintains the swapped-out settings. These result in error messages on start-up, but do not affect the functioning of the switch. The configuration can be manually edited to remove the swapped sections that no longer apply.

4. Line Card 1 has been configured and then removed before the configuration was saved using the create config command. The user then wishes to enter this command, while keeping the previous configuration of the line card that has been hot swapped out.

When the create config command is entered, the switch retains the configuration of the line card that has been hot swapped out. For example, if the original configuration included the command add vlan=”V2” port=1.1-2.4, the show config dynamic command would display the following configuration even though ports 1.1-1.8 no longer exist:

# # vlan configuration # add vlan="v2" port=1.1-1.8 add vlan="v2" port=2.1-2.4

If the switch is then restarted, some of the commands fail and the resulting dynamic configuration is:

# # vlan configuration # add vlan="v2" port=2.1-2.4 # # vlan swapped out port configuration add vlan="v2" port=1.1-1.8

This situation is potentially problematic because the switch has been restarted before the line card was hot swapped back in. The remaining examples describe possible ramifications.

5. (continuing from the end of Example 4) The switch is powered down and a different type of line card (for example, a 48-port line card) is inserted into slot 1. The switch is then powered up.

Ports 1.1-1.8 are configured as they were for the original 8-port line card. The remaining ports are added to the default VLAN.

Ultimately the line card is initialised to match as many of the commands that were previously configured as possible (some settings such as port speed are not possible).

6. (continuing from the end of Example 4) A line card is inserted into slot 1, and the configuration saved by using the command:

create config

The line card is initialised without configuration because the commands stored in the swapped out configuration that refer to this slot are all removed when the user creates a configuration.

Before the new line card was inserted, the configuration displayed by the show config dynamic command would have been:

# # vlan configuration

C613-03060-00 REV H

Hardware Reference 15

# add vlan="v2" port=2.1-2.4 # # vlan swapped out configuration add vlan="v2" port=1.1-1.8

After the new line card is inserted and the create config command is entered, the show config dynamic command displays the following configuration:

# # vlan configuration # add vlan="v2" port=2.1-2.4

7. (continuing from the end of Example 4) The wrong line card is accidentally inserted into slot 1. The user realises the mistake and removes the line card. The user has also already made further configuration changes, and saves the configuration by using the command:

create config

Because the line card that was inserted by accident has been hot swapped, creating a configuration removes the commands stored in the swapped-out configuration. When the correct line card is inserted, it is initialised without configuration.

To avoid loss of the swapped-out configuration in this situation, insert the correct line card, and restart the SwitchBlade. Then make the other configuration changes and create the configuration.

Where this card is used to replace the 8 port AT-SB4411, a general rule is to first use the centre 8 ports shown within the dotted line. This is to equally distribute the traffic across the card’s two ASIC switch instances and their connections to the intercard backplane. However, where heavy traffic is anticipated between ports that are both connected to this card, we recommend that these ports be grouped within the same switch instance. This will maximise throughput by locally switching the heavy traffic, and minimise traffic flow across the backplane.

Alarm Relays and Monitoring

This section provides an introduction to the SwitchBlade’s alarm and monitoring capabilities. All SwitchBlade chassis have two alarm relays on their rear panel, and extensive software-based logging, SNMP trap, and trigger monitoring capability.

Alarm Relays

The SwitchBlade’s two alarm relays (“Major” and “Minor”) can be configured to operate when a number of different environmental and operational events occur. Users can choose which relay (major or minor) operates for a specific event. The relays do not operate by default, they will only operate if specifically configured to do so.

The relays are designed to operate in DC circuits. When placed in these circuits the relays can operate external alarm devices such as small alarms, lights, or larger relays. If connecting the relays to a 12VDC circuit, they can switch 1 amp. If connecting the relays to a 48VDC circuit, they can switch 0.5 amp. The relays have normally open (N/O) and normally closed (N/C) contact options.

Connecting the relays to an AC circuit is likely to damage the relays and switch.

Table 1 on page 32 lists the events that can operate alarms. Refer to

“Environmental Monitoring” on page 4-15 of Chapter 4, Configuring and Monitoring the System for information on configuring alarm relays, including

complete command descriptions.

Command port (Asyn 0) status Initiates alarm and or monitoring events when a user logs

into Asyn 0 on the master switch controller.

Monitoring

In addition to operating an alarm, the events listed in Table 1 on page 32 can also be monitored. Users can configure monitored events to generate any combination of SNMP traps, logging events, and triggers. Monitoring does not occur by default, users must configure each event that is to be monitored. The SwitchBlade Software Reference has more information on monitoring, including complete command descriptions.

How Many PSUs do You Need?

The number of PSU’s required depends on the chassis type and the particular configuration selected, i.e. the number of line cards, controller cards installed. Consult your authorised Allied Telesis distributor or reseller for more information.

For PSU specifications and maximum current loads, see “AT-SB4161 & 2 SwitchBlade Power Supply Units” on page 19.

3. To load a file from AT-TFTP Server to the Switch.

On a terminal connected to the master switch controller’s RS-232 ASYN0, type the command:

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-TFTP Server.

4. To save a TFTP Server log.

Select "Save As" from the File menu.

TFTP requests are logged to the AT-TFTP Server main window.

Switch Start-up

This section outlines the log in and start-up procedures for your switch. Although the switch will perform basic switching operations without being configured, you will need to go through these log in and start-up procedures if you wish to configure the switch and access its full layer 3 switching capabilities.

Before you can log in, the switch’s chassis must have at least one power supply unit, one fan tray, and one switch controller installed.

C613-03060-00 REV H

To log In

To log in you must first connect the master switch controller to a terminal or PC. This can be done using the switch controller’s RS-232 ASYN0. Tw o terminal cables suitable for use with ASYN0 are supplied with each chassis.

If two switch controllers are installed, and the switch has not yet been connected to a power supply, the switch controller in Bay A will assume master controller status. In all cases the master controller is the controller whose Master LED is lit.

36 SwitchBlade 4000 Series Switch

Using the supplied terminal cable, or a cable you have made by following the instructions in “Useful Cables” on page 41, connect your terminal or PC to the RS-232 ASYN0 on the master switch controller.

Set the communication parameters on your terminal or terminal emulation program to:

• Baud rate: 9600

• Data bits: 8

•Parity: None

•Stop bits: 1

• Flow control: Hardware

See “Using Windows Terminal and Hyperterminal” on page 59 for more information on configuring emulation software.

Ensure that the chassis’s stand-by switch is in the Run position and that the switch controller is receiving power.

After the switch controller has booted, the log in prompt appears. If the log in prompt doesn’t appear, press [Enter] two or three times.

When the switch boots for the first time it automatically creates an account with manager privileges. The account has the log in name “manager” and the password is “friend”.

At the log in prompt, enter the log in name and password.

The switch’s command prompt appears and you can now configure the switch using the command line interface.

Change the password as soon as possible. Leaving the manager account with the default password is a serious security risk. Make sure that you remember the new password as there is no way to retrieve it if it is lost.

Use the following command to change the account password:

set password

See the SwitchBlade Software Reference for more information on configuring the switch.

Start-up Procedures

When the switch starts up following either a power cycle or an operatorinitiated reboot (using the Reset button or RESTART command), a series of start-up messages is sent to the terminal or PC connected to RS-232 ASYN0 (Figure 2 on page 37).

Figure 2: Switch start-up messages.

INFO: Self tests beginning. INFO: RAM test beginning. PASS: RAM test, 262144k bytes found. INFO: BBR tests beginning. PASS: BBR test, 512k bytes found. INFO: Self tests complete INFO: Downloading switch software. Force EPROM download (Y) ? INFO: Initial download succeeded INFO: Executing configuration script <boot.cfg> INFO: Switch startup complete

Manager >

After the self tests are complete, the manager is given the option of forcing a mandatory boot from the EPROM (Flash) release. The message:

Force EPROM download (Y)?

is displayed on the terminal or PC connected to ASYN0 and the switch pauses. If a key is not pressed within a few seconds, the start-up process will continue and all steps in the sequence will be executed. Pressing selected keys on the terminal immediately after the “Force EPROM download” message is displayed will change the switch start-up process (Table 2 on page 37).

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

[Y] Load the EPROM release, with no patch.

[S] Start with the default configuration. Any boot script is ignored.

[Ctrl/D] Enter diagnostics mode.

During the start-up process the switch will generate four different types of messages. All messages are preceded by one of the words INFO, PASS, FAIL, or ERROR. The significance of these words is shown in Table 3 on page 38.

Management Interfaces

This section introduces the switch controller’s RS-232 Terminal Port (ASYN0) and RJ-45 port (ETH0), including their pin assignments.

RS-232 Terminal Port (ASYN0)

C613-03060-00 REV H

The RS-232 ASYN0 Terminal Port can be used to connect the switch to a management device for initial configuration and switch management tasks. This allows the switch’s software to be accessed from a terminal, a PC running terminal emulation software, or from a remote location via a modem connection. You can also use ASYN0 to establish a network connection from a remote site using SLIP and a modem.

ASYN0 has a DCE female socket. This allows the use of a straight-through cable when connecting the switch to a terminal or PC. Output from the SHOW ASYN command will, however, still have a DTE perspective. The internal DTE pin roles are listed in Table 4 on page 40. See “Useful Cables” on page 41 for more information on suitable cables to use with ASYN0.

RJ-45 Management Port (ETH0)

Caution. Do not plug a phone jack into any RJ-45 port. Doing so could damage the switch. Use only twisted pair cables with RJ-45 connectors.

The switch controller’s 10BASE-T/100BASE-TX RJ-45 ETH0 port can be used to establish a connection to a dedicated network management LAN. ETH0 is not a switch port.

ETH0 has a default IP address of 192.168.242.242 and a mask of 255.255.255.0. For instructions on changing the IP address, see the “Graphical User Interface” section in the “Operations” chapter of the SwitchBlade Software Reference.

As a security precaution, change the default IP address as soon as possible.

If another device on your network already uses 192.168.242.242, do not connect ETH0 to the network until you have changed its default address.

A twisted pair straight-through cable with RJ-45 connectors should be used with ETH0. SeeTable 6 on page 41 list the cables described in this section. “Useful Cables” on page 41 for more information on suitable cables to use with ETH0.

C613-03060-00 REV H

Hardware Reference 41

With 10BASE-T/100BASE-TX cables, pins 1 and 2 are used for transmitting data, while pins 3 and 6 are used for receiving data. Table 5 on page 41 lists the RJ-45 Pin assignments.

Pin assignments

For twisted pair cables each pair is identified by two different colours. For example, one wire might be red, and the other red with a white stripe. An RJ-45 connector must be fitted to both ends of the cable.

Caution. Do not plug a phone jack into any RJ-45 port. Doing so could damage the switch. Use only twisted pair cables with RJ-45 connectors.

10/100BASE straight-through cable

If a twisted pair cable is to join two 10/100BASE network ports and only one of the ports has an internal crossover (only one port is labelled with an “X”), the two pairs should be straight through, as listed in Table 8 on page 43.

Test Facility

This section introduces the Test Facility. The Test Facility is built into all SwitchBlade software. For detailed information on operating the Test Facility, see the Test Facility chapter of the SwitchBlade Software Reference.

Any interfaces being tested are dedicated to the Test Facility. The Test Facility can be thought of as a specialised interface module like PPP or Frame Relay.

Ethernet LAN Port Tests

A crossover cable is required to run an Ethernet LAN test. See “Useful Cables” on page 41 for details of how to make a suitable cable. To start the test, loop a crossover cable between any two RJ-45 line card ports and enter:

ENABLE TEST INT=ALL

All interfaces connected by crossover cables are tested. Test results are displayed with the command:

C613-03060-00 REV H

SHOW TEST INT

which produces a display like that shown in Figure 6 on page 46. A more detailed output (with frame counts) can be displayed with the command:

Check these first

1. Check the power cord(s) connection(s).

2. Check that the power supply voltage is stable.

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

4. Make sure that other network devices are working properly.

5. Use the SHOW INSTALL command to check that the latest software version is loaded. See the SwitchBlade Software Reference for more information about obtaining the latest software version.

6. If the switch is malfunctioning, reboot it by pressing the recessed Reset button or entering the command RESTART REBOOT. Alternatively, use the standby switch on the chassis’s rear panel to power OFF and ON the switch.

Some common problems and how to solve them

Link/Activity LED on any port is off

This can indicate:

■ A loose data cable.

■ The device at the other end of the connection is not working 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.

Perform the following steps in sequence:

1. Make sure the data cable connections are secure.

2. Make sure the device at the other end of the connection is switched on and working properly.

3. Check that the data cable is wired correctly.

4. If you can, log in and check the port status. See “To log In” on page 35 for more information on how to log in.

5. If the port is Enabled, make sure the transmission speed matches that of the connected device (auto-negotiating, full or half-duplex).

If the port is disabled, someone has used the software to manually disable it. You should find out why the port was disabled before enabling it.

Power LED is off

This can indicate:

■ A loose power cord.

■ A power supply failure.

Perform the following steps in sequence:

C613-03060-00 REV H

Hardware Reference 51

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 for your particular chassis type and power supply. Refer to the section, “Physical and Operating Specifications” on page 15 of this manual.

Fault LED is on

This can indicate:

■ There is a problem with the switch or PSU.

■ The switch or management software is malfunctioning.

■ A hardware fault is preventing switch start-up.

Perform the following steps in sequence:

1. Check “LEDs and What They Mean” on page 47 for descriptions and explanations of LED flashing sequences.

2. Reset the switch by pressing the recessed RESET button on the front panel.

3. If you were attempting to download software or manage the switch via the RS-232 Terminal Port, check that connections between the Terminal Port and local terminal or PC are secure.

If you cannot access the switch’s software because of a faulty RS-232 Terminal Port connection, you can still manage the switch via Telnet or SNMP until the problem is fixed.

4. Remove the switch controller from the chassis and then re-insert it.

5. Download the latest software version. See the SwitchBlade Software Reference for more information on how to obtain the latest software version.

Content Addressable Memory (CAM)

CAM is an adaptation of random access memory (RAM) specifically designed to produce extremely fast look up times. Unlike conventional forms of RAM whose data content is accessed by referring to specific addresses, CAM operates by using the content data as addresses. Stored in each CAM location may be either the required data entity, or an address (in RAM) where it can be found.

Typically, the content data might be a table of Ethernet addresses and the required data entities could be either the switch ports to forward each frame to, or a RAM address where the forwarding port information can be found. The fast lookup times are achieved because, for each lookup, the entire contents of the CAM is simultaneously accessed and compared (within the hardware logic circuitry) with the reference data - a MAC address, for example.

C613-03060-00 REV H

There is a component of CAM (typically 40 K entries) located on each controller and line card.

52 SwitchBlade 4000 Series Switch

Switch Controller Card CAM

The switch controller card (SB4211) contains two CAM processor chips. Each chip contains 8 k entries of content addressable memory (CAM). These entries contain address locations for the forwarding database of L2/3 addresses and other similar entries such as VLAN identities. Located alongside each processor chip are 3 CAM chips that together provide an additional 96 k entries. Each processor chipset therefore, contains a total of 104 k entries of oncard CAM.

Line Card CAM

Each line card comes with a basic 40 k entries of CAM per switch processor chip. These entries contain address locations for the forwarding database of L2/3 addresses and other similar entries such as VLAN identities. Each switch chip contains 8 k entries of content addressable memory (CAM). Located alongside each switch chip is a CAM chip that provides an additional 32 k of CAM entries, thus producing a total of 40 k entries per on-card chipset.

Refer to the card descriptions shown in the “Physical and Operating Specifications” on page 15 for more information on the above line cards.

Expansion Options

This section provides a brief overview of the expansion options for the SwitchBlade. Contact your authorised Allied Telesis distributer or reseller for more information on these products, or visit our Web site at,

Dual In-line Memory Modules (DIMMs)

RAM for SwitchBlade switch controllers is provided in the form of two 128 MByte DIMMs. The two DIMMs deliver 256 MBytes of Synchronous DRAM.

To minimise the risk of damage during shipment, DIMMs are not installed on switch controllers at the factory. Instead, the two 128 MByte DIMMs are included in a CPU memory pack, which ships with each switch controller.

Installing DIMM

AT-SB4211 switch controllers have two DIMM slots. Both of these slots must be populated with a 128 MByte DIMM before the switch controller can be used.

Only Allied Telesis supplied DIMMS have been tested and approved for use with SwitchBlade switch controllers. Using DIMM that has not been approved may cause unreliable operation and will invalidate the switch controller’s warranty.

To install a DIMM

1. Prepare the switch controller.

C613-03060-00 REV H

Hardware Reference 53

If the switch controller is installed in a chassis, remove it by following the instructions in the SwitchBlade Switch Controller Quick Install Guide. The quick install guide can be found on the CD-ROM shipped with each switch controller and chassis, and can be downloaded from

www.alliedtelesis.com/support/software.

Lay the switch controller on a flat surface.

2. Prepare the DIMMs.

In an antistatic environment, remove the two DIMMs from their packing material. Be sure to observe ESD precautions.

Do not attempt to install DIMM without observing correct antistatic procedures. Failure to do so may damage the DIMM and switch controller. If you are unsure what the correct procedures are, contact your authorised Allied Telesis distributor or reseller.

A chassis ground socket is provided on the front vent panel of the SwitchBlade chassis. This socket is designed to be used in conjunction with an ESD wrist strap.

3. To remove an existing DIMM.

Each DIMM is held in place by two retaining latches, one latch at each end of the DIMM slot. Release these latches and carefully pull the DIMM from the DIMM slot.

The location of DIMM slots is shown in Figure 8 on page 53.

4. Align and insert the first DIMM.

Holding a DIMM at an angle of about 30 degrees from horizontal, align the notches on its connector strips with the notches on an empty DIMM slot (see Figure 8 on page 53).

Insert the DIMM into the DIMM slot, sliding it along the two DIMM guides until the retaining latches automatically click into place. The latches should hold the DIMM firmly in place.

5. Insert the second DIMM.

Repeat Step 4 for the second DIMM.

For the switch to function, both DIMMs must be installed (giving 256 MBytes of DRAM per switch controller).

Testing DIMM

The switch is unlikely to boot unless the DIMM is correctly installed. The switch controller’s fault LED will flash slowly if the DIMM is not detected. The fault LED will flash quickly if the DIMM is not of an acceptable type.

If the switch does boot but you suspect the DIMM is malfunctioning, or if you hot swapped in a switch controller with new DIMM, enter the command:

SHOW SYSTEM

to display the system information shown in Figure 9 on page 55. In the output’s memory section there should be an entry showing the size of DRAM. If the DRAM size is less than the size of DIMM that has been installed, then the switch has not correctly detected the DIMM. The most likely cause is that the DIMM connector is not plugged into its slot correctly. Repeat the installation process, paying particular attention to the DIMM insertion step.

After repeating the installation, use the SHOW SYSTEM command again, and if the display is still not correct, contact your authorised Allied Telesis distributor or reseller.

If you have any difficulty with the DIMM at any time, contact your authorised Allied Telesis distributor or reseller and quote the serial numbers of both the base card on the switch controller and the DIMM. The switch controller’s serial numbers and revision details can be read using the SHOW SYSTEM command. It’s a good idea to record this information for later reference.

Gigabit Interface Converters (GBICs)

The AT-SB4441 line card provides ports for eight GBICs. These are small hot-swappable plug-in transceivers. By selecting the appropriate GBIC type, you can match your SwitchBlade ports to their appropriate network interface. RJ-45 copper, SC and LC fibre GBICs are currently available.

GBIC 1000BASE-T Auto-Negotiation

The 1000BASE-T GBICs operating in the AT-SB4441 line card will provide only 1000 Mbps full-duplex connections. Although these GBICs will participate in auto-negotiation processes, they will only advertise 1000 Mbps. Half duplex, 10BASE-T, and 100BASE-TX modes are not supported.

While 1000BASE-T GBICs will auto-negotiate at the copper Ethernet level, the ports will behave as if in fixed 1000 Mbps full-duplex mode. This is because the SERDES connection used by GBIC ports makes the auto-negotiation invisible to the switch, and so prevents a successful link negotiation.

The following Allied Telesis GBIC transceivers can be ordered from your authorisedAllied Telesis reseller.

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:

• Select Programs > Accessories > Communications > HyperTerminal.

• Double-click the Hypertrm.exe icon.

2. In the Connection Description dialog box:

• Enter a name for the connection, such as Admin.

• Select an icon from the scrollable list and click the OK button.

Restricted Procedures

This section contains procedures that should only be performed by authorised service personnel. Unauthorised use of procedures in this section may cause danger of injury from electric shock, damage to the switch, and invalidation of the product warranty.

If you would like to know more about the procedures outlined in this section, please contact your authorised Allied Telesis distributor or reseller.

Diagnostics

The switch software includes a set of diagnostic programs. These programs perform basic level checks of all system components. They do not run in conjunction with the normal operating code, and require that the system be totally dedicated to their use. A detailed knowledge of the way the switch hardware functions is necessary if diagnostics are to be used effectively.

The switch will not perform switching operations if diagnostics are running.

This section is not intended as a guide to the diagnostics software. Diagnostics are designed to be run by service personnel only. For more information, contact your authorised Allied Telesis distributor or reseller.

To enable diagnostics mode

1. Connect a terminal to the RS-232 Terminal Port (ASYN0).

Using a terminal cable, connect a terminal to RS-232 (ASYN0) on the master switch controller. See “Useful Cables” on page 41 for more information on terminal cables.

Set the terminal communication parameters to the following:

• Baud rate: 9600

• Data bits: 8

•Parity: None

•Stop bits: 1

• Flow control: Hardware

2. Restart the switch.

Restart the switch, either by using a pen or pencil to operate the recessed reset button on the switch controller’s front panel, or by using the terminal to log in and enter the command:

RESTART REBOOT

See “To log In” on page 35 for more information on how to log in.

3. Enable diagnostics mode during start-up.

During the switch start-up process, at the prompt:

Force EPROM download (Y)?

press [Ctrl/D] on the terminal to enter diagnostics mode. A banner page will be displayed on the terminal (Figure 10 on page 63). This can be used to check that the terminal is correctly connected.

Performing a Full Flash Test or erasing flash will delete all configuration and release files. Make sure you know how to reload these files before erasing flash or performing a flash test.
