IBM and non-IBM racks
Verify that you are not exceeding the maximum weight load limits for IBM and
non-IBM racks.
Table 2 shows the maximum weight limits for IBM NetBAY racks and expansion
units that are recommended for use with BladeCenter S chassis. The table shows
the maximum number of BladeCenter S chassis that can be installed in a NetBAY
rack when the rack is:
v
Installed in place and sitting on the rack leveling pads.
v Being relocated and is sitting on the rack castors.
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” on page 87 to record your information.
