HighWire HW400c/2 User Reference Guide Rev 1.0
2.10.4 Power Requirements
The power requirements of the HW400c/2 are defined for two environments:
• CompactPCI VIO of 5.0v (see Table 3)
• CompactPCI VIO set 3.3v (see Table 4).
1. All voltages are required.
2. The CompactPCI VIO has no effect on the local PCI bus VIO (PTMC sites), which is fixed at 3.3v.
