Connecting The Ptx5000 To External Devices - Juniper PTX5000 Hardware Manual

10. Connect the negative (–) DC source power cable to the -48 V/60A input terminal (see
on page 273). Using a 7/16-in. (11-mm) nut driver, tighten the nut to secure the cable lug to the
input terminal.
11. Verify that the source power cables are connected to the appropriate terminal: the positive (+)
source cable to the return terminals (labeled RTN) and the negative (–) source cable to the input
terminals (labeled –48V/60A).
12. Replace the terminal block safety cover and ensure that the cables fit into the slots of the safety
cover.
13. Repeat the procedure for the input power terminals for all the PSMs in the PDU.
14. Repeat the procedure for the other PDU.
15. Verify that the DC power cables do not touch or block access to the components, and that they do
not drape where people could trip on them.
