WARNING: The switch is pluggable type A equipment that is installed in a restricted-
access locaon. The switch has a separate protecve earthing terminal provided on the
chassis in addion to the grounding pin of the power supply cord. You must
permanently connect this separate protecve earthing terminal to earth ground for
installaons that require a separate grounding conductor to the chassis.
WARNING: To comply with GR-1089 requirements, ensure that all intrabuilding copper
cabling used for SFP+ and QSFP+ ports are shielded and grounded at both ends.
CAUTION: Before you install the switch, a licensed electrician must aach a cable lug
to the grounding cables that you supply. See . A cable with an incorrectly aached lug
can damage the switch.
Before connecng the switch to earth ground, review the following informaon:
