Earlier Design Cheetah 512 and 1024 Series Upper-Top Fan Replacement Procedure
Perform the following fan replacement procedure:
For the earlier Design Cheetah 512 and 1024 Series switcher systems that are
to remain energized during a fan replacement sequence, it is extremely
important to remove all personal conductive materials (e.g., watches, rings,
and bracelets) during the replacement sequence. Additionally, exercise
extreme caution as to not drop any tools and/or parts that could reach the
active components (DC bus, boards/cards, etc.) in the chassis.
1.
Remove the filter/breaker panel assembly to access the upper top fan power connections
and fan assemblies (see Figure 95).
