The 4-wide Legacy Vertical power/controller carriers supply power and communications connections for vertically mounted controller(s) and I/O cards. There are two types of 4-wide Legacy Vertical power/controller carriers:
- Top 4-wide Legacy Vertical power/controller carriers connect to the left Legacy Vertical 8-wide I/O interface carrier. The 96 pin connector is at the bottom of this carrier. (The left 8-wide Legacy Vertical I/O interface carrier holds cards 1-8 from top to bottom.)
- Bottom 4-wide Legacy Vertical power/controller carriers connect to the right 8-wide Legacy Vertical I/O interface carrier. The 96 pin connector is at the top of this carrier. (The right 8-wide Legacy Vertical I/O interface carrier holds cards 8-1 from top to bottom.)
Up to two controllers (primary and secondary) and two system power supplies mount on the 4-wide Legacy Vertical power/controller carriers. The following figure shows the top and bottom 4-wide Legacy Vertical carriers.
