Figure 5-4 SANbox-16 Multistage with two T_Port links from each IO/T chassis

Figure 5-4shows a Multistage Switch built from SANbox-16 chassis. Two T_Ports on each IO/T chassis connect to the CC chassis. This provides 200 MBytes of bandwidth between each IO/T chassis and failover in case a T_Port fails. Each IO/ T chassis distributes the available T_Port access among its user ports. If a T_Port fails, the chassis distributes the user ports from the failed T_Port to other T_Ports that are good.

There are 14 user ports remaining on each IO/T chassis. All user ports may be F, FL, SL, or TL_Ports.
