Notes:
1. The weight values for the Universal Telco Framework and Seismic 2- and 4-post
2. These racks have not been NEBS-tested with the BladeCenter T installed.
When determining your floor load limits, use the combined weight of the rack,
populated BladeCenter T units, power distribution units 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 at your site. Worksheets
are provided in Appendix A, "Planning worksheets," on page 89.
Moving IBM NetBAY racks safely
It is very important to ensure that you move racks safely. For 42U racks, all
equipment installed above 22U in the rack must be removed before a rack can be
moved to another location. Before moving a rack, be sure to carefully read the
instructions that are provided with your rack.
