Upgrading the MX960 DC Power Supplies Overview
To upgrade the MX960 DC power supplies:
1. Remove one existing old power supply from either slot 0 or slot 3 (either far left or far
right), and replace it with a high-capacity power supply.
2. On the high-capacity power supply, rotate the metal cover away from the input mode
switch to expose the switch.
3. Move the input mode switch to position 0 for one feed or position 1 for two feeds.
NOTE: For a fully redundant configuration in two-feed mode, 8 feeds are
required. For a non-redundant configuration, 4 feeds are required.
