How to Remove UCS Chassis Slot Divider

The following process is used to remove a UCS chassis slot divider for insertion of a full width-blade:

1. Simultaneously pull up on the left side catch and push down on the right side catch
2. Pull the slot divider out of the chassis.  Keep the slot divider handy in case it is needed in the future.

 

To reinstall the slot divider, align it with the dimples in the slot top and bottom and slide it back in until it clicks into place.

*Note: The picture shows the use of a screwdriver to move the catches in the divider; I was able to perform this with just my fingernails
