Cabling the Power Input Module ERX Edge Routers

4-5

Follow the procedure in this section to connect power cables to the system. Refer to Figure 4-2as needed.

Caution: Before you begin this procedure, ensure that both Power A and Power B switches are in the OFF position.

1Loosen the four screws from the clear power input module cover.

2Remove the cover by sliding it upward so that the screw heads line up with the holes in the cover.

3Set the cover and screws aside for later use.

4Connect the ground wire to the ground terminal on the lower portion of the power input module, and secure it with a #10 kep nut.

Note: We recommend a minimum of 10-AWG ground wire with a ring-style terminal.

5Connect the other end of the ground wire to the appropriate ground termination lead.

Warning: Be sure the power source is turned off and the ERX system is turned off before continuing with this procedure.

6With the wrench or nut driver, loosen the 3/8" hex nuts from the bottom –48 VDC and RTN leads of Power A, and connect a 10-AWG wire to each.

7With the wrench or nut driver, tighten the hex nuts on both leads.

8Attach the opposite end of Power A’s wire leads to the appropriate leads on your power source.

Note: To provide redundancy, Power A and Power B leads should not terminate at the same power source.

9Repeat Steps 68for Power B.

10Reattach the clear power input module cover that you removed in step 1 by securing the four screws.
