CAUTION: You must ensure that power connections maintain the proper polarity.
The power source cables might be labeled (+) and (–) to indicate their polarity. There
is no standard color coding for DC power cables. The color coding used by the
external DC power source at your site determines the color coding for the leads
on the power cables that attach to the terminal studs on each power supply.
NOTE: For information about connecting to DC power sources, see “MX10003 Router DC
Power Specifications” on page 43.
6. Verify that the power cables are connected correctly, that they are not touching or blocking access to
router components, and that they do not drape where people could trip on them.
7. Repeat Step 1 through Step 6 for installing the other power supplies.
