8.3 Maintenance Precautions
Note the following points during maintenance on the XSCF unit.
  1. Do not replace the XSCF unit and the XSCF interface unit at the same time during system-stopped/cold maintenance. If you replace both the XSCF unit and the XSCF interface unit at the same time, the system will fail to operate normally. Replace the XSCF unit in the hot state and then replace the XSCF interface unit in the cold state.
  2. Do not mount and use any of the following microSD cards in the XSCF unit in another chassis:
    - the one currently mounted in the crossbar box, or
    - one that was once used as a maintenance part
    This is because these microSD cards store device identification information.
  3. When replacing the microSD card at the same time as the XSCF unit of a crossbar box in a SPARC M10 system, do not replace them during system-stopped/cold maintenance. Doing so may put the Oracle Solaris clock greatly out of sync at system startup.
    Replace them during system-stopped/hot maintenance.
  4. If you replace the microSD card along with the XSCF unit, dispose of the microSD card mounted on the old XSCF unit by appropriate means such as cutting it with cutting pliers. The old microSD card stores the user information, IP address, and other information set in the XSCF firmware.
