EMC D-PEXE-IN-A-00 Dell PowerEdge XE9680 and XE8640 Install Exam Practice Test

Understanding Stab-in Rails:

Stab-in rails are designed to simplify the server installation process. These rails enable a quick and straightforward installation of the server into the rack.

Compatibility and Usage:

Stab-in rails are specifically designed for use in 4-post racks with square holes. This compatibility ensures stability and proper fitting within the rack structure.

Installation Process:

Before initiating the installation, verify that the rack is a 4-post, square hole type.

Position the stab-in rails to align with the square holes on the rack. Typically, stab-in rails have tabs that fit precisely into these square holes.

Mounting the Server:

Once the rails are securely attached to the rack, the server can be mounted. The design of the stab-in rails facilitates a smooth insertion of the server, ensuring it is securely held in place.

Ensuring Proper Fit:

After the server is mounted, check to ensure that it is level and securely attached. This step is crucial to prevent any movement or displacement that could occur due to vibrations or physical disturbances.

Dell EMC Technical Specifications Guide: Offers comprehensive specifications and compatibility information for different mounting and installation hardware used with Dell PowerEdge servers.

Understanding Rail Types and Compatibility:

Dell PowerEdge servers, including the XE8640, come with rail kits designed for specific types of racks. The rail kits are tailored to fit racks with square holes or threaded holes, depending on the model and configuration.

Compatibility with Round-Hole Racks:

The PowerEdge XE8640 does not support installation in round-hole racks. The rail kits provided with the XE8640 are designed for 4-post racks with square holes or 4-post threaded racks. Attempting to install these rails in a round-hole rack will result in improper fitment and stability issues.

Common Installation Issues:

If the outer rail portion does not fit flush with the rack frame, it is often due to a compatibility issue with the rack type. Round-hole racks require specific rail kits that are different from those used for square or threaded hole racks.

Verifying Rack Type:

Before installation, verify the type of rack being used. Ensure that it matches the specifications outlined in the server's installation guide. Using the correct rack type ensures proper fitment and structural integrity.

Alternative Solutions:

If the current rack is a round-hole type, consider using a compatible rack with square or threaded holes for the XE8640. Alternatively, there might be adapters or conversion kits available that allow the use of standard rails in round-hole racks, although these are not typically recommended due to potential stability issues.

The PowerEdge XE9680 server is equipped with power supply units (PSUs) that are essential for its operation. Here’s the power consumption information that the deployment engineer can provide:

PSU Specifications: Each PowerEdge XE9680 server comes with four 2800-Watt, 15.6 Amp PSUs1. This specification is crucial for the data center manager to understand the power requirements for each server.

Total Power Requirement: With two servers per rack, each rack will have a total of eight 2800-Watt PSUs. This information helps in calculating the total power draw for each rack.

Power Distribution Units (PDUs): While the number of PDUs required for high availability can vary, it’s important to note that the server’s PSUs feature a C22 input socket1. The data center manager should ensure that the PDUs in the rack are compatible with this type of connection.

Power Planning: The data center manager must plan for the power needed to supply power to the four racks, considering the power draw of the servers and any additional equipment that will be installed.

By providing this detailed power consumption information, the deployment engineer assists the data center manager in planning for the appropriate power infrastructure to support the PowerEdge XE9680 servers.

To ensure the correct server rails are on-site for the installation of PowerEdge XE servers, it’s essential to match the server model with the appropriate rail type. Based on the Dell Enterprise Systems Rail Sizing and Rack Compatibility Matrix, the following matches are correct:

XE9680 and B25: The XE9680 server is compatible with the B25 rail type, which is designed to support the size and weight of this particular server model1.

XE9640 and B25: Similarly, the XE9640 server can also utilize the B25 rail type for secure mounting in a rack1.

XE9680 and B28: Additionally, the XE9680 server is compatible with the B28 rail type, providing an alternative mounting solution1.

It’s important to note that the rail types are specific to the server models and are designed to ensure a secure and stable installation in the customer’s rack. The Dell Rail Sizing and Rack Compatibility Matrix provides detailed information on the compatibility of different server models with their respective rail types. This document should be consulted to verify the correct rail type for each server model before proceeding with the installation1.
