Question #2

A deployment engineer is installing an XE9680 server. The network connectivity has 24 optical cables that route to switches in the data center. The administrator questions the use of a cable management arm (CMA).

What are two items to consider when installing a CMA?

A . The CMA can be installed to open on either the left or right side of the server.
B . Do not route optical cables through the CMA.
C . A CMA can only be installed with a strain relief bar.
D . The XE9680 does not support a CMA.

Explanation:

When installing a Cable Management Arm (CMA) on the Dell PowerEdge XE9680 server, there are specific considerations to ensure proper installation and operation: CMA Orientation:

Installation Flexibility: The CMA for the XE9680 can be installed to open on either the left or right side of the server. This flexibility allows for better management of space within the rack and ensures that the CMA can accommodate the specific layout of your data center (Dell) (Dell). Cable Routing:

Avoid Routing Optical Cables Through the CMA: Optical cables are typically more sensitive and less flexible compared to other types of cables. Routing them through the CMA can lead to bending, twisting, or other stresses that may damage the cables and affect network performance. Therefore, it is advised not to route optical cables through the CMA(Dell)(Dell). Installation Process:

Align and Install the CMA: Attach the CMA to the designated mounting points on the server rails. Ensure that it is securely fastened and aligned properly to avoid any issues when extending or retracting the server from the rack.

Organize Cables: Use the provided cable management features to route and secure other cables,

ensuring they are not pinched or overly stressed. Avoid including optical cables in the CMA to

prevent potential damage.

Post-Installation Checks:

Verify Movement: Ensure that the server can be smoothly extended and retracted with the CMA in place without any cables getting caught or strained.

Secure Connections: Double-check all cable connections to ensure they are secure and functioning correctly.

These steps are crucial for maintaining the integrity and performance of the server and the connected network infrastructure. Proper cable management not only ensures safety but also enhances the reliability and maintainability of the data center setup.

Question #4

A deployment engineer is connecting the network cables on an XE9680 server. The data center administrator wants to know why the server does not have an OCP card for network connectivity.

How should the engineer respond to the administrator’s query?

A . An OCP card is required for the server to achieve POST when powered on.
B . The LOM card acts as an OCP card and supports OCP 3.0.
C . The OCP card is an optional component.
D . The server does not support an OCP card.

Question #5

A deployment engineer is installing a PowerEdge XE8640 server in a rack with round holes. They cannot get the outer rail portion to fit flush with the rack frame.

What is the reason the outer rail is not flush with the frame?

A . The rail latch is not engaged.
B . The PowerEdge XE8640 does not support a round-hole rack.
C . A small offset is expected between the rail mounting post and the rack.
D . Weight has not been applied to the rail.

Explanation:

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.

Reference and Documentation:

Refer to the Dell EMC PowerEdge XE8640 Installation and Service Manual for detailed information on rail and rack compatibility. This manual provides specifications for supported rack types and instructions for proper installation.
