Connecting the ACX5048 and ACX5096 to Power
Connecting the ACX5000 Router to Earth Ground
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the ACX5000 router to earth ground before you connect it to power.
For installations that require a separate grounding conductor to the chassis, you must attach a protective earthing terminal bracket on the ACX5000 router left front mounting bracket to connect to the earth ground (see Figure 1).
Before you connect earth ground to the protective earthing terminal of a ACX5000 router, ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable.
You must install the ACX5000 router in a restricted-access location and ensure that the chassis is always properly grounded. The ACX5000 router has a two-hole protective grounding terminal provided on the chassis. See Figure 1 and Figure 2. We recommend that you use this protective grounding terminal as the preferred method for grounding the chassis regardless of the power supply configuration. However, if additional grounding methods are available, you can also use those methods. For example, you can use the grounding wire in the AC power cord or use the grounding terminal or lug on a DC power supply. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-hole protective grounding terminal.
Using a grounding cable with an incorrectly attached lug can damage the router.
Mount your router in the rack or cabinet before attaching the grounding lug to the router. See Mounting an ACX5000 Router in a Rack or Cabinet.
Ensure that you have the following parts and tools available:
-
Protective earthing terminal bracket—This bracket attaches to the router chassis through the left front mounting bracket, providing a protective earthing terminal for the router.
-
Grounding cable for your router—The grounding cable must be 14 AWG (2 mm²), minimum 90° C wire, or as permitted by the local code.
-
Grounding lug for your grounding cable—The grounding lug required is a Panduit LCD10-10A-L or equivalent.
-
Two M4 hex nuts with integrated washers—Two nuts and washers are used to secure the grounding lug to the grounding lug bracket protective earthing terminal. Four nuts are provided in the accessory kit.
-
7-mm wrench or socket with driver to attach the two nuts.
An AC-powered ACX5000 router chassis gains additional grounding when you plug the power supply in the router into a grounded AC power outlet by using an AC power cord appropriate for your geographical location. See AC Power Cord Specifications for an ACX5000 Router.

Ensure that you have a power cord appropriate for your geographical location available to connect AC power to the router.
Before you begin connecting AC power to the router:
Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).
Ensure that you have connected the router chassis to earth ground.
CAUTION:Before you connect power to the router, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the router (for example, by causing a short circuit).

Install the power supply in the chassis. For instructions on installing a power supply in a ACX5000 router, see Installing a Power Supply in an ACX5000 Router.
The power supply in an ACX5000 router is a hot-removable and hot-insertable field-replaceable unit (FRU). You can remove and replace it without powering off the router or disrupting routing functions.
Each power supply must be connected to a dedicated power source outlet.
