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.

1. Be sure you have completed Task 1 and Task 2 in the previous sections.
2. If applicable, loosen the screws from the clear power input module cover
and remove it.
