6. Executethe showboards command to check the state of the chassis requiring
maintenance.
TheBB-ID o ft he chassis requiring maintenance is indicated by the system board
(PSB) number.
Inthe following example, we can see that [PPAR-ID] of PSB 01-0 is "00".
7. Executethe poweroff command to stop all the logical domains on the
physicalpartiti onrequiri ngmaintenance.
Inresponse to the confirmation message, enter "y".
8. Execute the showpparstatus command to confirm that the power to the
physicalpartiti oni s turned off.
Inthe fo llowing example, [PPAR Status] of PPAR-ID 00 displays "Powered Off",
which indicates that the power to the physical partition has been turned off.
9. Switchthe mode switches for the master chassis and those chassis whose
XSCFsare in the standby state to Serv ice mode.
-Fora building block configuration (without crossbar box)
Switchthe m ode switches of BB-ID#00 and #01 to Service mode.
-Fora building block configuration (with crossbar box)
Switchthe m ode switches of BB-ID#80 and #81 to Service mode.
