Connect the PTX10004 Router to Earth Ground
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you
must connect the chassis to earth ground before you connect it to power.
You must install the PTX10004 in a restricted-access location and ensure that the chassis is always properly
grounded. The PTX10004 has a two-hole protective grounding terminal provided on the chassis. See
Figure 63 on page
149. Under all circumstances, use this grounding connection to ground the chassis. For
AC-powered systems, you must also use the grounding wire in the AC power cord along with the two-hole
grounding lug connection. This tested system meets or exceeds all applicable EMC regulatory requirements
with the two-hole protective grounding terminal.
If an external ground connection is required, ensure that a licensed electrician has attached an appropriate
grounding lug to the grounding cable you supply. Using a grounding cable with an incorrectly attached lug
can damage the switch.
NOTE:
Mount your router in the rack before attaching the grounding lug to the router; see
"Install the PTX10004 into a Rack" on page
Ensure that you have the following parts and tools available:
An electrostatic discharge (ESD) grounding strap (provided).
Protective earthing terminal lug (provided).
Grounding cable for your PTX10004 (not provided)—The grounding cable must be 4 AWG (21.1 mm²)
stranded wire should be rated 75° C or per local electrical code.
Grounding lug for your grounding cable (provided)—This bracket attaches to the lower left corner of the
router chassis next to the bottom power supply, providing a protective earthing terminal for the router.
The grounding lug required is a Panduit LCD6-14A-L or equivalent.
A number 3 Pozidriv or Phillips screwdriver (not provided) to tighten the two screws that are mounted
on the chassis.
The provided terminal lugs for the JNP10K-PWR-DC2 are Panduit LCD4-14A-L, or equivalent, and sized
2
for 4 AWG (21.1 mm
) power source cables. The 4 AWG (21.1 mm²) stranded wire should be rated 75° C
or per local electrical code. We recommend that you install heat-shrink tubing insulation around the crimped
section of the power cables and lugs.
An AC-powered PTX10004 gets 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
"PTX10004 Power Cable Specifications" on page
