Discuss Cisco 800-150 Exam Topic 2 Question 21

What must be considered when installing a new fan module in a fixed-configuration Cisco Nexus switch?

AThe size of the fan module must match the power supply.

BFan modules can be installed only when the switch is powered off

CThe airflow direction must be consistent with other installed modules.

DThe fan module must be from the same manufacturing batch as the others.

Suggested Answer: C

When installing a fan module in a Cisco Nexus fixed-configuration switch, it's crucial to ensure that the airflow direction of the new fan matches the existing airflow configuration. Mismatched airflow directions can lead to inefficient cooling or even overheating of components, potentially affecting the performance or lifespan of the switch.

Cisco offers fan modules in front-to-back or back-to-front airflow variants, and consistency is required for proper thermal management. These modules are also typically hot-swappable, meaning powering down the switch is not necessary.

I’m uncertain about the power supply matching the fan module size; it seems like it could be relevant, but I can't remember the details.

Tamekia 3 months ago

I practiced a question like this before, and I feel like the switch definitely needs to be powered off for installation.

Fatima 4 months ago

I think fan modules need to be from the same batch, but I can't recall if that's a strict requirement or just a recommendation.

Keneth 4 months ago

I remember something about airflow direction being really important, but I'm not sure if it's the only thing to consider.
