MX10003 Router Grounding Specifications
Grounding Points Specifications
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, the router must be adequately grounded before power is connected. To ground AC-powered and DC-powered routers, you must connect a grounding cable to earth ground and then attach it to the chassis grounding points by using the two screws provided.
Figure 1 shows the grounding point location on the router.
A protective earthing terminal bracket is required for connecting the chassis to earth ground. This two-holed bracket attaches on the side of the chassis through the mounting rail and provides a protective earthing terminal for the switch. The grounding points are studs sized for M4 hex screws. M4 hex screws with integrated washers are provided in the accessory kit. The grounding points are spaced at 0.75-in. (19.1-mm) centers.
Two threaded holes are provided on the front right side of the chassis for connecting the router to earth ground. The grounding points fit M5 pan head screws.
Additional grounding is provided to an AC-powered router when you plug its power supplies into grounded AC power receptacles.

Grounding Cable Lug Specifications
The accessory box shipped with the router includes one cable lug that attaches to the grounding cable and M4 hex screws used to secure the grounding cable to the grounding points .
Before router installation begins, 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.
Grounding Cable Specifications
The grounding lug required is a Panduit LCD10-14B-L or equivalent (not provided). The grounding lug accommodates 14–10 AWG (2–5.3 mm²) stranded wire. The grounding cable that you provide for the chassis must be the same size or heavier than the input wire of each power supply. Minimum recommendations are 14–10 AWG (2–5.3 mm²) stranded wire, 60° C wire, or as permitted by local code.

MX10003 Router Clearance Requirements for Airflow and Hardware Maintenance
When planning the installation site, allow sufficient clearance around the rack (see Figure 2):
For the cooling system to function properly, the airflow around the chassis must be unrestricted. Allow at least 6 in. (15.2 cm) of clearance between side-cooled routers. Allow 2.8 in. (7 cm) between the side of the chassis and any non-heat-producing surface such as a wall.
For service personnel to remove and install hardware components, there must be adequate space at the front and back of the router. At least 24 in. (61 cm) are required both in front of and behind the router. NEBS GR-63 recommends that you allow at least 30 in. (76.2 cm) in front of the rack and 24 in. (61 cm) behind the router.
To accommodate power cable bend radius at the rear of the chassis and the interface cable bend radius at the front of the chassis, provide at least 2.75 in. (7 cm) at the rear and 3.5 in. (8.9 cm) at the front.

MX10003 Router Rack Requirements
The router can be installed in a standard 19-in. rack. Many types of racks are acceptable, including four-post (telco) racks and open-frame racks. Table 3 summarizes rack requirements and specifications for the router.
Table 3: Router Rack Requirements and Specifications
Rack Requirement | Guidelines |
|---|---|
Rack type and mounting bracket hole spacing | Use a four-post rack. You can mount the router on any four-post rack that provides bracket holes or hole patterns spaced at 1 U (1.75-in./4.44-cm) increments and that meets the size and strength requirements specified in this table. A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Components Industry Association (http://www.ecianow.org/). |
