Ultra Enterprise 6000/5000/4000 Systems Manual—November 1996

5.5.2.2 Cooling and Power Issues

There should be one power/cooling module (PCM) for every two boards to
adhere to cooling and power requirements. The PCMs must be installed
adjacent to populated board slots to ensure the fan in the PCM can cool the
respective boards.

Note – All empty board slots in Enterprise 4000 or 5000 systems must have a
filler panel installed to ensure proper cooling. All empty slots in Enterprise
6000 systems must have load boards installed.

5.5.2.3 Powered or Nonpowered On System

1. Carefully insert the board (component side down if in front; component

side up if in the rear) in the proper slot in the card cage, ensuring that the
board does not slip out of the left and right card guides.
See Figure 5-7.
