Product Guide

Use multiple pairs of second-tier switches to build larger IntelliFlex systems. Systems with up to 36 first-tier groups can be supported using two to four pairs of second-tier switches.

When multiple pairs of second-tier switches are used, every first-tier switch must connect to all second-tier switches on the same fabric. Uplinks should be evenly distributed across all second-tier switches.

When connected to a UDA network, the second-tier switches can be used for UDA connections. Distribute the UDA connections evenly across all pairs of second-tier switches for best performance.
