Table 1: Troubleshooting JCS1200 Power Problems

Symptom	Action
The JCS1200 platform does not start.	Make sure that: All power cords are connected to a compatible power source and that the power sources are working (see Connecting the JCS1200 AC Platform to AC Power or Connecting the JCS1200 DC Platform to DC Power). The input power and output power LEDs on the power modules are lit. If you just installed an optional device, remove it. If the JCS1200 platform now starts, you might have installed more devices than the power modules support. You might have to install power modules in power module bays 3 and 4.
