Page 51: Stacking Guidelines
SBx908 GEN2 Installation Guide for Virtual Chassis Stacking Stacking Guidelines Here are general stacking guidelines:  A stack can have two, three, or four switches.  Stacking requires v5.4.8-0.2 or later of the AlliedWare Plus management software. Instructions later in this guide explain how to view the version number of the operating software on the switches.
Page 52: Stack Trunk
 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 53: Figure 15: Example Trunks For Stacks Of Two, Three, Or Four Switches
SBx908 GEN2 Installation Guide for Virtual Chassis Stacking Stack with Two Chassis Stack with Three Chassis Stack with Four Chassis Figure 15. 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 54: Figure 16: Stack Of Three Switches With A Linear Trunk
Chapter 2: 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 16. This trunk topology is not recommended.
Page 55: Figure 17: Example Of A Trunk With Multiple Links Between Switches
SBx908 GEN2 Installation Guide for 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 17 uses ports on XEM2-12XS Line Cards to build a stack of three switches, with a trunk of three links from switch-to-switch.
Page 56: Figure 18: Example Of A Stack Trunk Of Ports On Multiple Line Cards
Chapter 2: Virtual Chassis Stacking  You can further improve the resiliency of trunks by distributing the ports onto multiple cards in the switches. This makes it possible for trunks to continue functioning, though at reduced bandwidths, even if line cards with trunk ports fail. The example in Figure 18 is a stack of three switches with a trunk of two links from switch-to- switch, on different line cards.
Page 57: Table 15: Maximum Number Of Trunk Ports Per Switch
SBx908 GEN2 Installation Guide for Virtual Chassis Stacking  Table 15 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 XEM2-12XS Line Cards.
Page 58: Figure 19: Unsupported Trunk With Too Many Stacking Ports
Chapter 2: Virtual Chassis Stacking Chassis 1 Chassis 2 Figure 19. Unsupported Trunk with Too Many Stacking Ports  You can use any line card in the chassis for the trunk. Furthermore, as stated earlier, the ports of the trunk can be from different cards in a chassis, so long as all the cards are the same model.
Page 59: Figure 20: Stack With Three Chassis
SBx908 GEN2 Installation Guide for Virtual Chassis Stacking  With stacks of three or four switches, the number of physical links in the trunk has to be the same on all switches. The example in Figure 20 is a stack of three chassis with a valid trunk of two links between chassis 1 and 2, chassis 2 and 3, and chassis 3 and 1.
Page 60: Figure 21: Unsupported Trunk Because Switches Have Different Numbers Of Trunk Links
Chapter 2: Virtual Chassis Stacking  Figure 21 is an example of an unsupported 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 61: Figure 22: Unsupported Trunk With Different Ethernet Line Card Models
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 22 is unsupported because it has ports from XEM2-4QS and XEM2-12XT Line Cards. Chassis 1 Chassis 2 Chassis 3...
Page 62: Figure 23: Example Of A Stack Trunk Of Ports On Xem2-8Xstm Line Cards
Chapter 2: Virtual Chassis Stacking  The XEM2-8XSTm Line Card has four twisted pair ports and four SFP+ ports. When building a trunk with the ports on this line card, you can use either the twisted pair or SFP+ ports, but not both. Figure 23 is an example of a trunk of SFP+ ports on XEM2-8XSTm Line Cards for a stack of three switches.
Page 63: Figure 24: Unsupported Trunk With Both Direct Connect And Fiber Optic Cables On Xem2-12Xt Line Cards
SBx908 GEN2 Installation Guide for Virtual Chassis Stacking  The XEM2-12XS Line Card supports 10Gbps 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 64: Figure 25: Unsupported Trunk With Both Direct Connect And Fiber Optic Cables On Xem2-4Qs Line Cards
Chapter 2: Virtual Chassis Stacking  The XEM2-4QS Line Card also supports QSFPICU and QSFP3CU direct connect cables. As with the XEM2-12XT Line Card, you can build stack trunks using XEM2-4QS Line Cards with either direct connect cables or fiber optic transceivers, but not both. Figure 25 is an example of an unsupported trunk on XEM2-4QS Line Cards because it uses both direct connect and fiber optic cables.
Page 65: Figure 26: Example Of A Stack Trunk With Xem2-1Cq Line Cards
SBx908 GEN2 Installation Guide for Virtual Chassis Stacking  You can use XEM2-1CQ Line Cards for a stack trunk. But since the card has only one 100Gbps transceiver port, each switch has to have two cards for the trunk. Figure 26 is an example of a stack trunk of four switches with the line card.
Page 66: Figure 27: Unsupported Trunk Because A Chassis Is Connected To Three Other Chassis
Chapter 2: 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 27 is unsupported because chassis 1 has trunk links to all three of the other switches.
Page 67: Figure 28: Unsupported Trunk With Intermediary Network Devices
SBx908 GEN2 Installation Guide for Virtual Chassis Stacking  Trunk links must be direct connections between ports on the line cards. A trunk cannot have any intermediary network devices, such as media converters, routers, or other Ethernet switches. Figure 28 is an example of an unsupported trunk because it has intermediary network devices, in this case media converters.
Page 68: Master And Member Switches
Chapter 2: Virtual Chassis Stacking Master and Member Switches A stack has a master switch. A stack can have only one master switch at a time. Its main functions are listed here:  Coordinate and monitor stack operations.  Verify that the switches are using the same version of management software.
Page 69: Switch Id Numbers
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.
