Connecting The Optical Ila Grounding Cable - Juniper PTX3000 Hardware Manual

Connecting the Optical ILA Grounding Cable

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. For installations that require a
separate grounding conductor to the chassis, use the protective earthing terminal on the optical ILA chassis
to connect to the earth ground.
NOTE: An AC-powered optical ILA gains additional grounding when you plug the power supply
in the device into a grounded AC power outlet by using an AC power cord appropriate for your
geographical location. See
CAUTION:
attach a cable lug to the grounding and power cables that you supply. A cable with an
incorrectly attached lug can damage the optical ILA (for example, by causing a short
circuit).
NOTE: Mount the optical ILA in the rack or cabinet before attaching the grounding lug to the
optical ILA. See "Mounting an Optical ILA in a Rack or Cabinet" on page 55
Power System" on page 31
Ensure that you have the following parts and tools available (none are provided):
Grounding cable—The grounding cable must be 14–10 AWG (2–5.3 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 LCD6-14BH-L or
equivalent.
Two #10-32 UNF screws
Screwdriver appropriate for the #10-32 UNF screws.
To connect a grounding cable to the optical ILA:
1. Connect one end of the grounding cable to a proper site earth ground, such as the rack in which the
optical ILA is mounted.
2. Place the grounding lug attached to the grounding cable over the protective earthing terminal on the
chassis (see Figure 23 on page
"AC Power Cord Specifications for the Optical ILA" on page
Before you connect power to the optical ILA, a licensed electrician must
