Juniper MX960 Hardware Manual page 641

To install an MX960 high-capacity DC power supply:
1. Verify that the power switch on the power supply is in the off (O) position.
2. On the 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 (see
Figure 117 on page 346).
NOTE: For a fully redundant configuration in two-feed mode, eight feeds are required.
For a nonredundant configuration, four feeds are required.
