11. Dress the power cord appropriately. Verify that the power cord does not block the air exhaust and
access to router components, and that they do not drape where people could trip on them.
12. Move the AC input switch above the power supply to the on (—) position. This is the only switch you
have to turn on if you are using the power supply in one feed mode. If using the power supply in
two-feed mode, move the power switch on the power supply to the on position. Remember to turn on
both switches when operating the power supply in two-feed mode.
13. If the power supply is correctly installed and functioning normally, the AC1 OK, AC2 OK (two-feed
mode only), and DC OK LEDs light steadily, and the PS FAIL LED is not lit. See Table 113 on page 340.
14. Repeat steps 1-12 for installing power supplies in slots 1, 2, and 3, where present
