Roy, I encountered a similar issue with a 7204VXR + I/O-2FE/E + NPE-225.
I worked with TAC and started by replacing both power supplies; no good. This router was due for an NPE-G1 upgrade so I installed the replacement and kept the I/O controller installed; no good. I finally pulled out the I/O controller and that solved the problem. -mtw ________________________________________ From: [email protected] [[email protected]] On Behalf Of roy [[email protected]] Sent: Tuesday, September 22, 2009 03:52 To: [email protected] Subject: [c-nsp] 720x VXR -12V Sensor Does anyone know which IC is being used by the 720x VXR router for monitoring the voltage readings (specially the one for -12V)? I've looked around and seems the DS1620 on I/O card is only for temperature. I could be wrong though. Would appreciate if anyone can point me into the right docs. Trying to troubleshoot an internal -12V issue which shuts down my 7206VXR upon reaching the threshold within 5 minutes of power-up. This happens on C7206VXR chassis, NPE-400, I/O-2FE/E controller. I have only been looking into the I/O controller. All tray fans working; input voltage good and clean on either/both PSU's. Inlet/outlet temps within range.
