B-2 Dell PowerEdge Cluster (PowerEdge 4200) Installation and Troubleshooting Guide
S
upported Stand-Alone
Configurations
Figures B-1 and B-2 show the stand-alone configurations
of the PowerEdge Cluster that Dell supports. These con-
figurations are specified to provide a safe operating
environment for the cluster components.
As evident in the figures, two general rules govern the
stand-alone configurations:
•
The heaviest cluster component must be at the bot-
tom of the stack and the lightest component at the
top.
•
No more than a single PowerEdge Scalable Disk
System 100 (SDS 100) storage system or a single
network switch can be stacked on top of a
PowerEdge server. If stacked alone, the storage
system(s) and network switch may be stacked one on
top of the other with the network switch on top, as
shown in Figure B-2.
NOTE: Placement of the monitor, keyboard, or mouse on
top of the PowerEdge systems or the SDS 100 storage
system(s) is not supported by Dell. Also, Dell does not
support more than one network switch stacked in any
stand-alone configuration of the cluster components.

ack Safety Notices
Before you begin installing the PowerEdge Cluster
components in your rack, carefully read the safety
precautions and installation restrictions in the following
subsections.
Kit Installation Restrictions
This rack kit is intended to be installed in a Dell Rack-
Mountable Solutions enclosure by trained service
technicians. If you install the kit in any other rack, be
sure that the rack meets the specifications of the Dell
rack.
Rack Stabilizer Feet
Refer to the Dell PowerEdge Rack-Mountable Solutions
Installation Guide provided with the rack for instructions
on installing the stabilizer feet.
WARNING: Dell’s server systems are certified as
components for use in Dell’s rack cabinet using the
Dell Customer Rack Kit. The final installation of
Dell servers and rack kits in any other brand of
rack cabinet has not been approved by any safety
agencies. It is the customer’s responsibility to have
the final combination of Dell servers and rack kits
for use in other brands of rack cabinets evaluated
for suitability by a certified safety agency.
WARNING: Installing a PowerEdge system in a
Dell rack without the front and side stabilizer feet
installed could cause the rack to tip over, resulting
in bodily injury. Therefore, always install the stabi-
lizer feet before installing components in the rack.
WARNING: After installing computers in a rack,
never pull more than one computer out of the rack
on its slides at one time. The weight of more than
one computer extended on slides could cause the
rack to tip over and cause bodily injury.
