Removing The Chassis Intrusion Switch - Dell PowerEdge R930 Owner's Manual

NOTE: If the intrusion cable is missing or not connected, a notification is received in the ESM and intrusion status is not logged
in the system event log.
The chassis intrusion switch detects any unauthorized access into the interior of your system and provides an indication of the same. This
switch is activated as soon as the system cover is removed and access is made to the interior of your system.
The chassis intrusion switch is located on the Network Daughter Card (NDC) riser, connected to the NDC riser card. It is used to detect
unauthorized access to the inside of the system. The intrusion is indicated on the Embedded Server Management (ESM) when the system
cover is open.
