D20 VME Chassis<br />
The chassis-mounted power supply modules are switch-mode converters that provide<br />
output power for the <strong>D20MX</strong> processor board, VME cards, modems and D20 Peripheral I/O<br />
modules, as required. A redundant power supply can be installed to provide fail-over<br />
protection to ensure continuous power to the D20.<br />
If you have an extended system with more than five peripherals, the chassis-mounted D20<br />
power supply is not adequate. In this case, you need to install an external power supply.<br />
Table 5 lists the standard power supplies that are available. Other power supplies are<br />
available for specific requirements. Contact <strong>GE</strong> <strong>Digital</strong> <strong>Energy</strong> for details.<br />

Ensure your D20 power input is externally protected for over-current; otherwise damage to<br />
the <strong>D20MX</strong> may occur. The required fuse rating depends on the power consumption of<br />
your system.<br />
The D20 available power supplies, listed in Table 5 are equipped with two field replaceable<br />
fuses.; see Figure 5.<br />
