Juniper Networks 8 manual Task 2 Connect the Grounding Cables, Task 3 Connect the Power Cables

Cabling ERX Routers

Task 2: Connect the Grounding Cables

All ERX routers have two grounding studs located in the rear of the chassis, near the power inputs. Each stud provides grounding for a single power unit.

To ground each power unit:

1.Locate the grounding studs on the router (Figure 26 and Figure 27).

2.Remove the nuts and locking washers from the grounding studs.

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

3.Place the grounding cable lead on one of the grounding studs and tighten the nuts to secure the connection.

4.Connect the other end of the ground cable to the appropriate ground termination lead.

5.Repeat Steps 3–4 for the remaining grounding stud.

NOTE: When grounding an ERX router, leave a service loop in the grounding cable to ensure that the grounding cable is the last cable to disconnect from the shelf if strain is placed on the electrical cables.

Task 3: Connect the Power Cables

To connect power cables to the router, follow these steps. Refer to

Figure 26, Figure 27, and Figure 28 as needed.
