Removing and replacing Tier 1 CRUs

Replacement of Tier 1 CRUs is your responsibility. If Lenovo installs a Tier 1 CRU at your request, you will be charged for the installation.

A working NeXtScale n1200 Enclosure might have numerous power cables, Ethernet cables, and fiber cables that are connected to components on the front and rear of the chassis:
  • You might have to disconnect some of the cables when you remove and replace a Tier 1 CRU.
  • Make sure that the surrounding cables allow adequate clearance before you remove and replace a Tier 1 CRU.
  • Do not pinch, bind, or pull on the cables when you remove and replace a Tier 1 CRU.
  • Do not allow unsupported cables to exceed a safe bend radius. For example, a disconnected fiber cable might bend back on itself and become damaged.

The illustrations in this document might differ slightly from your hardware.
