Emprise 7000 Installation and Service Guide 44
Cable Routing Example: Minimize Switches
The following configuration minimizes purchases of additional switch products as ISE are added
to a configuration. This allows a user to add up to 21 ISE to a system before adding an additional
switch pair for ISE 22.
Important
: To ensure that failover functions correctly and to optimize performance of the
Emprise 7000 system, use the Emprise 7000 Configuration Guide for the specific port
connectivity that applies to the system you are installing.
