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.
