Grounding the SRX1400 Services Gateway


To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must properly ground the services gateway chassis before connecting power.


Before you connect power to the services gateway, a licensed electrician must attach a cable lug to the grounding cable that you use. A cable with an incorrectly attached lug can damage the device (for example, by causing a short circuit).

To connect the services gateway to earth ground:

  1. Verify that a licensed electrician has attached the cable lug provided with the services gateway to the grounding cable. The cable must be 14-AWG (2.1 mm2), minimum 60°C wire.
  2. Attach an ESD grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site.
  3. Ensure that all grounding surfaces are clean and brought to a bright finish before you make the grounding connections.
  4. Connect the grounding cable to a proper earth ground.
  5. Detach the ESD grounding strap from the site ESD grounding point.
  6. With the ESD grounding strap attached to your bare wrist, connect the strap to one of the ESD points on the chassis.
  7. Place the grounding cable lug over the grounding point—a pair of M5 holes to the left of the power supply slots. See Figure 1.

  8. Secure the grounding cable lug to the chassis using washers and screws.
  9. Dress the grounding cable, and verify that it does not touch or block access to device components and it does not cause a tripping hazard.
