Step 2. Replace each IBM standard I/O book, originally installed in the server, with a Lenovo standard I/O
book, that comes with the ITL kit (see “Replacing the standard I/O book” on page 227 for
information and instructions).
Note: The service technician will need to perform this procedure twice when upgrading an IBM
x3950 X6 server to a Lenovo x3950 X6 server.
a. Remove the IBM standard I/O book from the shuttle (see “Removing the standard I/O book” on
page 224 for instructions).
Important: Before opening the release levers to extract the standard I/O book from the
system, look for missing or broken tabs on the chassis that the release levers pry against.
Missing or broken tabs can make removal of the standard I/O book from the chassis difficult. If
tabs are missing or broken, open an online service request at
https://www.ibm.com/support/
servicerequest/Home.action
.
b. Transfer components and devices (adapters, fans, USB embedded hypervisor flash device,
and flash power modules) from the IBM standard I/O book, originally installed in the server, to
the new Lenovo standard I/O book, that comes with the ITL kit (see “Replacing the standard I/
O book” on page 227 for instructions).
Important:
• When installing the standard I/O book in the system, look for missing or broken tabs on the
chassis that the release levers pry against. Missing or broken tabs can make installation of
the standard I/O book in the chassis difficult. If tabs are missing or broken, open an online
service request at
https://www.ibm.com/support/servicerequest/Home.action.
• Check for the white bracket (stuck to mechanical wall under the air baffle). If it is present,
remove it.
• Make sure that the standard I/O book air baffle is fully seated, as shown in the following
illustration, before installing the standard I/O book in the chassis. You might need to adjust
placement of the fan cables to fully seat the air baffle.
