Replacing a compute book

This information provides instructions on how to replace the compute book.

Note
The information and installation procedures in this documentation apply to both the 4-socket and the 8-socket configurations of the server, unless otherwise specified. Most of the illustrations in the documentation show the 4-socket configuration of the server.

The following are notes and information that you must consider when you install the compute book in the server:

  • The compute books should be installed from left to right (facing the front of the server).
  • A minimum of two compute books must be installed in the 4-socket (x3850 X6) server.
  • A minimum of four compute books must be installed in the 8-socket (x3950 X6) server.
  • Each compute book must have a minimum of one microprocessor and one DIMM installed.
  • The 4-socket (x3850 X6) server supports compute book configurations of two or four. These are the only configurations supported. The following tables list the installation sequence for the supported compute book configurations.

  • The 8-socket (x3950 X6) server supports compute book configurations of four, six, or eight. These are the only configurations supported. The following tables list the installation sequence for the supported compute book configurations.

  • For a list of supported devices, see the Lenovo ServerProven website.

To install the compute book, complete the following steps:

  1. Reinstall the microprocessor and heat sink on the new compute book (see Replacing a microprocessor and heat sink).
  2. Reinstall the DIMMs (see Replacing a memory module).
  3. Replace the compute book covers. Align the cover over the rear of the compute book and slide it forward (toward the front of the compute book) until it is seated in place.
  4. Reinstall the fans (see Replacing a hot-swap fan assembly).
  5. Align the compute book with the slot on the server and slide it in the server. Place one hand under the center of the compute book to support it while sliding it into the server.

  6. Rotate the cam handle all the way up and push it into the server until it locks in place.
  7. Reconnect the power cord and any cables that you removed.
  8. Turn on the peripheral devices and the server.
