Restrictions on Replacing a Crossbar Box (Only for SPARC M12-2S)


Restrictions on Replacing a Crossbar Box (Only for SPARC M12-2S)
Replacement of a crossbar box using the replacefru(8) command is not supported at present. To replace a crossbar box, perform the following procedure:
  1. Execute the showhardconf command to confirm that the crossbar box to be replaced is not the master chassis.
    The crossbar box with the "Role:Master" indication is the master chassis.
XSCF> showhardconf
          :
   XBBOX#80 Status:Normal; Role:Master; Ver:2038h; Serial:2111206001;
          :
  1. If the crossbar box to be replaced is the master chassis, first execute the switchscf command to switch the box to standby.
XSCF> switchscf -y -t Standby
  1. The master XSCF is switched. Log in to the XSCF again.
  2. Power off the physical partition (PPAR) that uses the crossbar box, and then power off the crossbar box to be replaced.
    Confirm that the Power-LED on the operation panel of the crossbar box is turned off.
  3. Disconnect the power supply to the crossbar box to be replaced, and then replace it.
Note - Although error logs for the crossbar box to be replaced are registered when the input power supply is disconnected, they can safely be ignored.
  1. Connect the power cord of the crossbar box to the input power supply.
    For details, see "5.3  Connecting Cables to the Crossbar Box" in the Fujitsu SPARC M12-2S Installation Guide.
    Wait until the STANDBY-LED on the operation panel of the crossbar box goes on.
  2. Execute the diagxbu command to perform diagnosis of the newly installed crossbar box.
XSCF> diagxbu -y -b XX -t YY -t ZZ
  1. Specify the BB-IDs (00 to 15) of the powered-off SPARC M12-2S in XX, YY, and ZZ.
  1. Execute the showlogs command to confirm that no error occurred during the diagnosis.
XSCF> showlogs error
  1. Confirm that there are no faulty components.
XSCF> showstatus
