Additional Information
Noise immunity may be reduced and device damage may occur due to ground loops, which
may be caused by improper shield connections and grounding methods.
When using a baud rate of 100 Mbps or less, it may be possible to alleviate this problem by
connecting the shield only at the Ethernet switch side as described in (2), rather than connect-
ing both ends as described in (1).
• 1000Base-T
Connect the shields to respective connector hoods at both ends of the cables.
This connection is required for 1000Base-T to ensure compliance with EMC standards.
