1. Touch the Free Failed Crosspoint button to move all of the routes from the failed
video crosspoint module to the redundant video crosspoint if Workbench has not been
configured to do this automatically.
2. Check that the “Active” LED on the failed video crosspoint module is off and then
remove the failed video crosspoint module (see the Sirius 800 User manual for video
crosspoint location and section 7.1.1 for the location of the Active LED).
3. Replace the failed video crosspoint module with a replacement working crosspoint
module.
4. The replacement video crosspoint module is automatically tested and the Fault
Present indicator will change back to Green if the replacement is fully working.
5. Touch the Fault Fixed button to move all of the routes from the redundant video
crosspoint module to the fixed video crosspoint module.

• The fan assembly should be placed back into the closed position as soon as
possible after opening, as this ensures correct ventilation of the frame. Failure to
do this will result in failure.
• In practice the maximum time that a fan assembly can be left open will depend on a
number of factors such as; ambient temperature, frame loading, crosspoint
routings, etc. To ensure correct operation under all conditions the fan assemblies
should be left open for no more than 4 minutes at a time.
• Take care not to trap any cables when opening and closing the fan door.
