Application Note

Smart Slot Philosophy

For a Smart Slot configuration, the secondary slot is not required to be unique to each primary slot.

Instead, a single secondary slot can be shared among many primary slots. This technique provides

the highest density of modules to be fitted in a given physical space. Smart Slot between chassis can

be performed if the chassis are version 2 (or higher) as these have the connector fitted to enable

connection of a TC-006 that ensures the IMB 0V of each chassis is at the same potential.

TrustedTM AN-T80007 Smart Slot Philosophy Implementation Location of Smart slots Design considerations should be given to the location of smart slots within the system. One option is to allocate a spare slot on each chassis or per module type. Another option is to allocate one smart slot per system panel; if this option is selected then the IMB 0V of each chassis needs connecting together using a TC-006 cable.
