Check Physical Access to the Failed Chassis

Check Physical Access to the Failed Chassis

Perform the following checks on all Perform the following checks on all systems:

  1. Rack front and back doors are unlocked and can be opened.
  2. There is adequate space in front of the rack to pull the chassis out of the rack.
  3. The front bezel can be removed.
  4. There is adequate space to remove the chassis mounting screws.
  5. Space in front of the rack is free of cabling which would obstruct removal of the chassis.

...

Check whether all cables connected to the failed chassis are labeled correctly with the corresponding port information for unique identification during the HW swap from the failed chassis to the new chassis, and correct as needed. Label the cables that are not labeled.
