Fans
There are six non-replaceable factory-installed fans.
The 7450 ESS-1 cooling system requires a minimum of 3-inches of unrestricted unobstructed air
flow to function properly.
An MDA faceplate is required in an empty MDA slot to prevent excess dust accumulation and to
help control airflow and electromagnetic interference.
Storage
To store uninstalled 7450 ESS-1 switches and extra field-replaceable parts (if applicable), re-wrap
the components in the original packaging and keep them in a dry, dust-free temperature controlled
environment.
