7750 SR-a4 and SR-a8 Installation Guide
Impedance panels are required in all empty card and component slots to prevent excess dust
accumulation and to help control airflow and electromagnetic interference.
The air filter is factory-installed and is field-replaceable. The air filter must be in place before
the chassis is powered up.
The air filter should be inspected monthly. Replace the filter media when accumulated dust
is present.
Allow at least 20 in. (50.8 cm) in the front for installation and maintenance access.
To store an uninstalled 7750 SR-a4 or 7750 SR-a8 or extra field-replaceable parts (if
applicable), repackage the components in the original packaging or an appropriately sized
container and keep them in a dry, dust-free, and temperature-controlled environment.
