Page 41: Stacking Guidelines
 If you are using fiber optic transceivers for the trunk, the transceivers must be from Allied Telesis. Transceivers from other network equipment providers might not operate properly as part of a trunk link. For a list of supported transceivers, refer to the Allied Telesis web site.
Page 42: Figure 9: Example Trunks For Stacks Of Two, Three, Or Four Switches
Chapter 2: Virtual Chassis Stacking Stack with Two Chassis Stack with Three Chassis Stack with Four Chassis Figure 9. Example Trunks for Stacks of Two, Three, or Four Switches  The trunk configuration is referred to as a ring because the last switch in the stack is connected to the first switch, creating a loop.
Page 43: Figure 10: Stack Of Three Switches With A Linear Trunk
AT-SBx908 GEN2 Installation Guide for Virtual Chassis Stacking  You can omit the link from the last to first switches to create a linear trunk. An example of a stack with three switches in a linear trunk is shown in Figure 10. This trunk topology is not recommended.
Page 44: Figure 11: Example Of A Trunk With Multiple Links Between Switches
Chapter 2: Virtual Chassis Stacking  You can increase the bandwidth and resiliency of trunks by increasing the number of physical links between switches. The example in Figure 11 uses ports on AT-XEM2-12XS Line Cards to build a stack of three switches, with a trunk of three links from switch-to-switch.
Page 45: Figure 12: Example Of A Stack Trunk Of Ports On Multiple Line Cards
AT-SBx908 GEN2 Installation Guide for Virtual Chassis Stacking  You can further improve the resiliency of trunks by distributing the ports onto multiple cards in a switch. This makes it possible for trunks to continue functioning, though at reduced bandwidths, even if line cards with trunk ports fail.
Page 46: Figure 13: Invalid Trunk With Too Many Stacking Ports
Chapter 2: Virtual Chassis Stacking  Table 10 lists the maximum number of trunk ports that a switch can support at one time. The number varies by line card. For example, a switch can have a maximum of eight trunk ports when a trunk is build with ports on AT-XEM2-12XS Line Cards.
Page 47: Figure 14: Stack With Three Chassis
AT-SBx908 GEN2 Installation Guide for Virtual Chassis Stacking  Provided that all other rules are followed, trunk ports can be chosen from any line card in a switch. Furthermore, as stated earlier, they can all be on the same line card or different cards in a switch, so long as the cards are all the same model.
Page 48: Figure 15: Invalid Trunk Because Switches Have Different Numbers Of Trunk Links
Chapter 2: Virtual Chassis Stacking  Figure 15 is an example of an invalid trunk because the units do not have the same number of trunk links. There are two links between chassis 1 and 2 and chassis 2 and 3, but only one link between chassis 1 and 3.
Page 49: Figure 16: Invalid Trunk With Different Ethernet Line Card Models
AT-SBx908 GEN2 Installation Guide for Virtual Chassis Stacking  A trunk cannot have ports from different line card models. The trunk for the three switches in Figure 16 is invalid because it has ports from AT-XEM2-4QS and AT-XEM2-12XT Line Cards. Chassis 1 Chassis 2 Chassis 3...
Page 50: Figure 17: Invalid Trunk Using Both Direct Connect And Fiber Optic Cables On At-Xem2-12Xt Line Cards
Chapter 2: Virtual Chassis Stacking  The AT-XEM2-12XS Line Card supports 10Gbps AT-SP10TW direct connect twinax cables in addition to fiber optic transceivers. You can use direct connect cables for trunk links when switches are physically close together, such as in the same equipment rack or adjacent racks.
Page 51: Figure 18: Invalid Trunk Using Both Direct Connect And Fiber Optic Cables On At-Xem2-4Qs Line Cards
AT-SBx908 GEN2 Installation Guide for Virtual Chassis Stacking  The AT-XEM2-4QS Line Card also supports direct connect cables, called AT-QSFPICU and AT-QSFP3CU cables. As with the AT- XEM2-12XT Line Card, you can build stack trunks using AT-XEM2- 4QS Line Cards with either direct connect cables or fiber optic transceivers, but not both.
Page 52: Figure 19: Example Of A Stack Trunk With At-Xem2-1Cq Line Cards
Chapter 2: Virtual Chassis Stacking  You can use AT-XEM2-1CQ Line Cards for a stack trunk. But since the card has only one 100Gbps transceiver slot, each switch has to have two cards. Figure 19 is an example of a stack trunk of four switches with the line card.
Page 53: Figure 20: Invalid Trunk Because A Chassis Is Connected To Three Other Chassis
AT-SBx908 GEN2 Installation Guide for Virtual Chassis Stacking  In stacks of four chassis, no switch can have trunk links to more than two other chassis. The trunk example in Figure 20 is invalid because chassis 1 has trunk links to all three of the other switches. Chassis 1 Chassis 4 Chassis 2...
Page 54: Figure 21: Invalid Trunk Because Of Intermediary Network Devices
Chapter 2: Virtual Chassis Stacking  Trunk links must be direct connections between ports on line cards. A trunk cannot have any intermediary network devices, such as media converters, routers, or Ethernet switches. Figure 21 is an example of an invalid trunk because it has intermediary network devices, in this case media converters.
Page 55: Master And Member Switches
AT-SBx908 GEN2 Installation Guide for Virtual Chassis Stacking Master and Member Switches A stack has a master switch. The main functions of a master switch are listed here:  Coordinate and monitor stack operations.  Verify that the switches are using the same version of management software.
Page 56 Chapter 2: Virtual Chassis Stacking After the stack is established and operating, you may, if you choose, change the priority settings on the individual units and so control which switch will be the master switch after subsequent power cycles and resets.
Page 57: Switch Id Numbers
AT-SBx908 GEN2 Installation Guide for Virtual Chassis Stacking Switch ID Numbers Each switch must be assigned an ID number. The range is 1 to 4. The default is 1. The ID numbers are displayed on the ID LEDs on the front panels of the units.
Page 58: Optional Feature Licenses
Additional features and capabilities might be included with the operating system, but they can only be used after they are unlocked with optional feature licenses from Allied Telesis. Contact your authorized reseller or distributor for a list of optional features licenses for this product.
Page 59: Planning The Stack
AT-SBx908 GEN2 Installation Guide for Virtual Chassis Stacking Planning the Stack Here are factors to consider when planning a stack:  How many SBx908 GEN2 Chassis will be in the stack? The maximum is four chassis.  How many trunk links will there be between switches? The maximum numbers of permitted links vary by Ethernet line card and are listed in Table 10 on page 46.
