Safety
Before working in any GE Healthcare MR suite or performing any GE Healthcare service procedure, you must: Have read and understood all hazard conditions and safety requirements in the latest revision of the GE Healthcare MR Service Safety Manual (5452735). Have successfully completed all relevant GE Healthcare Environmental Health and Safety (EHS) courses (or for non-GE employees, equivalent workplace training courses).

Immediately contact your supervisor or site safety officer for instructions on how to proceed.

Procedure

With the slide rails out, install the new ICN, lining up the studs on the ICN with the slots on the rails.

Connect all other cables that were previously removed to the rear of the new ICN.

Figure 1. ICN cable connections (Gen 7, Dell R640)

Note:

Ethernet ports 1 & 3 are NOT used. Ethernet port 2 is used ONLY when the system is connected to a Raw Data Server (external to the MR System), it should be left free in all other cases. Not following this configuration may lead to VRE configuration failures and/or boot-up/TPS failures.

Push the two release tabs down and move the ICN all the way into the PGR cabinet until it locks in place.
Install 2 screws.
If applicable, connect any cables to the front of the ICN.
Restore all cabinet covers.
