The enclosure bezel for this model provides the EMI protection for the LFF disk drive modules. The bezel
should be securely attached to the enclosure during operation (see Enclosure bezel attachment on page 18
and Figure 8 on page 19).
CAUTION: Whether configured with or without an air filter, to ensure adequate EMI protection, the
enclosure bezel should be properly installed while the enclosure is in operation.
