Notes:
- The installation of side covers is optional on the 3931. For system dimensions without covers, see Physical dimensions.
- This weight does not include the weight for the Earthquake Kit
feature (FC 8014 or FC 8015).
- The Earthquake Kit hardware weighs approximately 43 kg (95 lbs).
If you are replacing an existing machine, also refer to the Installation Manual for Physical Planning for your existing machine (available on IBM Documentation; go to https://www.ibm.com/docs/en/systems-hardware, select IBM Z or IBM LinuxONE, then select your configuration, and click Library Overview on the navigation bar) to determine actual differences between your existing installed machine and the 3931. Plan views, physical dimensions, service clearances, aisle spacing, and power and cooling requirements may be substantially different.
