If your installation is not using a grounded-raised floor, and your servers are connected to an 9076 SP 
Switch2 clustered environment, all attached server frames in your environment must be independently 
grounded to the switch frame. Use the following information to help you install multiple systems to the 
9076 SP Switch2 switch frame in a clustered environment: 
v   Order grounding straps by calling the IBM Quality Hotline at 1-800-IBM-LINE and requesting Part 
Number 44P3695, Grounding Kit. Each kit contains one ground strap and the required hardware to 
make a single connection between a server and a 9076 SP Switch2, so order one kit for each server 
that is connected to the switch. 
v   An IBM service representative will install the grounding straps by using instructions that are provided 
with the grounding kits. Each server frame must be directly connected to a 9076 SP Switch2 frame.

Approximate System Weights by Configuration 
If the system that you order weighs more than 1134 kg (2500 lbs) when it is shipped from the factory, a 
weight-distribution plate will be provided for the system. This plate is used to minimize the point loading 
from casters and leveling pads.
