WARNING: Before working inside your Edge Gateway, read the safety information that shipped with your Edge Gateway. For more

safety best practices, see the Regulatory Compliance home page at www.dell.com/regulatory_compliance.

WARNING: Disconnect all power sources before opening the Edge Gateway cover or panels. After you finish working inside the

Edge Gateway, replace all covers, panels, and screws before connecting to the electrical outlet.

CAUTION: To avoid damaging the Edge Gateway, ensure that the work surface is flat and clean.

CAUTION: To avoid damaging the components and cards, handle them by their edges, and avoid touching pins and contacts.

CAUTION: You should only perform troubleshooting and repairs as authorized or directed by the technical assistance team. See the

safety instructions that shipped with the product .

CAUTION: Before touching anything inside your Edge Gateway, ground yourself by touching an unpainted metal surface, such as the

metal at the back of the Edge Gateway. While you work, periodically touch an unpainted metal surface to dissipate static electricity,

which could harm internal components.

CAUTION: When you disconnect a cable, pull on its connector or on its pull tab, not on the cable itself. Some cables have

connectors with locking tabs or thumb-screws that you must disengage before disconnecting the cable. When disconnecting

connectors are correctly oriented and aligned.
