D. Check the P/N updated
(1) Do the LRU identification check
(a) Get access to LRU ident page:
1 Select on MCDU the sequence that follows:

MCDU MENU->CFDS->SYSTEM REPORT/TEST->PAGE 2/2->AIR BLEED->BMC1(2)->LRU IDENT.

(2) Make sure that the installed BMC software P/N shown on the LRU IDENTIFICATION page is not the same as the BMC software P/N written on the front face of the new CD-ROM to load.
