Removing a CPI

Removing a CPI


Remove a central partition interconnect module (CPI) if it has failed.



No special conditions are required for this operation.


No data preparation is required for this operation.


  • ESD gloves
  • Packaging materials, for example, an ESD bag


  1. Log in to the central management console (CMC) CLI. For details, see Logging In to the CMC CLI.
  2. Determine that the CPI to be removed is standby.

    • Run the smmget -l cpiN -d redundancy command to determine whether CPI 1 or 2 is standby.

      For example, if the value of N in the command is 1, standby in the command output (as shown in the following information) indicates that CPI 1 is standby, and active indicates that CPI 2 is standby.

      root@SMM:/# smmget -l cpi1 -d redundancy 
      The Redundancy State of CPI: 
      CPI1: Present(standby)     
    • Observe the ACT indicator of each CPI to determine whether the CPI is active or standby. If the ACT indicator is off, the CPI is standby. If the ACT indicator is steady green, the CPI is active.

  3. Run the smmset -l cpi -d hotswap -v 0 command to unload the CPI. When the system asks you whether to confirm the operation, enter y and press Enter.

    root@SMM:/# smmset -l cpi -d hotswap -v 0 
    Are you sure to unmount the backup cpi.Continue?[Y/N]:Y 
    Unmount the backup CPI success. 
    You can plug out the backup CPI now.

  4. Remove all cables from the CPI.
  5. Hold down the plastic latches on the outer sides of the CPI ejector levers. See step (1) in Figure 6-25.
  6. Fully open the CPI ejector levers. See step (2) in Figure 6-25.
  7. Gently remove the CPI by holding its ejector levers. See step (3) in Figure 6-25.
  8. Place the removed CPI in an ESD bag.
