Verify that you are not exceeding the maximum weight load limits for IBM and non-IBM racks.
For on-site relocation of the rack on castors, the maximum number of BladeCenter S chassis, including the power distribution units (PDUs) to support the configuration, is based on a 14-degree stability requirement established under IBM safety guidelines.

When determining your floor load limits, use the combined weight of the rack, populated BladeCenter S chassis, PDUs, and other rack mounting hardware to ensure the installation site can safely support the total weight. Consult your local building engineer to understand the weight limits for your site. Use the Rack installation worksheet to record your information.
