Installation IT Guide Accuray Confidential part of the CyberKnife® System should be considered as a black box environment and part of an approved, tested configuration. The CyberKnife® System is composed of several computers running Windows and Red Hat© Enterprise Linux operating systems. They are connected to a managed switch, which contains the traffic of the various devices within various VLANs. The switch is attached to a router, which connects the CyberKnife® System to the hospital network. The Treatment Planning devices may be connected to the CyberKnife® System or to the hospital. Imposing any specific controls on the connection to the CyberKnife® System will be at the full discretion of the hospital, however, the CyberKnife® System devices themselves cannot be modified, and the requirements listed under section 10 must be fulfilled to maintain full operation of the CyberKnife® system. Accuray will abide with hospital policies to the point that the system configuration is not changed. If you have any questions or feedback regarding the CyberKnife® System, or about this document specifically, please contact Accuray Customer support by email at customersupport@accuray.com or by calling 1.877.668.8667.

Installation IT Guide Accuray Confidential 6.2 System Overview The CyberKnife® LAN contains the following parts: • UCC: User interface to Treatment Delivery System • IFCC: Controls communications between robot and Linear Accelerator. • MTS: Synchrony (motion tracking) • TLS: Imaging System • CDMS Data Server: Database server • MultiPlan (may exist outside LAN) • MD Suite (optional, may exist outside LAN) 6.3 Network Overview The CyberKnife® System network configuration is controlled by two devices: CK 9,x Network Hardware • Cisco ASA 2821 Firewall • HP ProCurve 2824 Switch CK 10.x Network hardware • Cisco ASA 5510 Firewall • Cisco 2960 Switch The Cisco router/firewall contains rule lists that separate the hospital LAN from the CyberKnife® System LAN, so as to prevent computers not explicitly allowed with CyberKnife® System treatments from accessing the CyberKnife® System LAN. The network switch uses VLANs to divide its ports. VLANs allow for a higher degree of control in the CyberKnife® System LAN, and it separates the user devices, such as MultiPlan, from the control devices, such as the CDMS Data Server. In one treatment network, there are three VLANs: the primary VLAN 185, the secondary VLAN 184, and the CDMS VLAN 183. The primary VLAN contains the treatment delivery system, whereas the secondary VLAN contains all the user devices, like MultiPlan, and finally, the CDMS VLAN only contains the CDMS. The use of VLANs provides another layer of security for the CyberKnife® System LAN, however, it adds a restriction where each device connects to a specific port on these switches. Each network device uses Category 6 Ethernet cables, to provide up to 1 Gbps, or 1000 Mbps, bandwidth. Each network has special port-forwarding rules to allow the communication of various devices within the CyberKnife® network with devices located on the hospital LAN: Hospital traffic (Local) • DICOM: Medical image transfer with CyberKnife® System devices and hospital modalities, e.g., PACS, CT, PET, etc. o o Traffic is initiated either inbound or outbound, based on the initiator of the traffic. Uses TCP/104. • CDMS: Stores and retrieves all CyberKnife® System related data, including planning/treatment. o o Traffic is initiated inbound to the CyberKnife Data Management System. Uses TCP/4000-4099. Primary port is TCP/4027. Verify Latest Printed Version Before Using Page 7 of 18 P/N 1022517, Rev. A
