Intruder Alert
The server base unit contains the circuitry for the intruder alert, which must be connected to the alert
switches in the top of the rack. If installing two Intergraph racks, where one contains only option
equipment (disk array cabinets, networking devices, etc.) then the expansion rack can be connected to
an adjacent rack containing the base unit. When unauthorized entry is made into the expansion rack,
the intruder alert in the base unit will activate. Chapter 3, “Using the System” of the System Setup
describes how to activate and de-activate the intruder alert.
To connect the intruder alert cable for an individual rack:
1. Connect the intruder alert cable to the intruder alert port. Intergraph installs the intruder alert
cable into the back of the rack before shipment.

2. Ensure the other end of the intruder alert cable, and the white loop-back connector are attached to
the sockets in the top corner of the rack. Refer to the following figure.
