Actual exam question for Dell EMC's D-PEXE-IN-A-00 exam

Question #: 28
Topic #: 3

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?

AThe CMA can be installed to open on either the left or right side of the server.

BDo not route optical cables through the CMA.

CA CMA can only be installed with a strain relief bar.

DThe XE9680 does not support a CMA.

Show Suggested Answer

Suggested Answer: A, B

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.

B) Do not route optical cables through the CMA. Duh, that's like Cable Management 101. Rookie mistake if you ask me.

Wait, the server has 24 optical cables? That's a lot of spaghetti to manage. I hope they have a dedicated cable wrangler on the team.

C) A CMA can only be installed with a strain relief bar. Gotta have that extra support, otherwise it's just a disaster waiting to happen.

B) Do not route optical cables through the CMA. That's a no-brainer, you don't want to risk damaging those expensive cables.

I vaguely recall that strain relief bars are important for stability, but I’m not confident if they’re mandatory for all CMAs.

I practiced a similar question where the CMA had to be compatible with the server, so I wonder if option D could be a trap.

I’m not entirely sure, but I feel like routing optical cables through the CMA could cause issues, so option B seems likely too.

I'm confident I can handle this. The CMA can open on either side, and as long as I don't use a strain relief bar, I should be good to go.

Okay, I think the key here is to avoid routing the optical cables through the CMA. That seems like the most important consideration based on the information provided.

Hmm, the XE9680 doesn't support a CMA? That's good to know. I'll make sure to double-check the server model's compatibility before trying to install one.
