This graphic displays the Ethernet routes and serial service for the SV system.
• Because CAM lite2 has no APS, so port 1 in Term Server is not used any more.
• Image data, status and control signal are transferred by the 1000M Ethernet switch.
• A VERY IMPORTANT THING TO REMEMBER: Image Compute Nodes are computers like your
PC... they must be shut down properly or they risk operating system corruption.
• ALWAYS follow service procedures when removing power to ICNs – shut them down via a
"soft power off" at the GOC, not by pushing the power button on the ICNs themselves or
by pulling the power cord. We will say this many times in this training!! In addition,
removing power to the Systems cabinet (or RF/Systems cabinet) without properly shutting
down the Volume Recon Engine subsystem will induce the possibility of corrupting the
operating system on the ICNs!!
• VRE can be safely powered down by 1) shutting down the host computer or 2) Using the
VRE power utility from the common service desktop
