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.
