Juniper MX80 Hardware Guide

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 “MX5,
MX10, MX40, and MX80 Routers DC Power Specifications” on page 39.
8. Replace the clear plastic cover over the terminals on the faceplate.
9. 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.
10. If you are installing two power supplies, repeat Steps 3 through 9 for the other power
supply.
