Release 12.1R6 New Features

Chassis Grounding for SRX1400 Through SRX5800 Services Gateways

In order to meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must properly ground the services gateway chassis before connecting power. This requirement applies to the following services gateway models without exception:

  • SRX1400 Services Gateway
  • SRX3400 Services Gateway
  • SRX3600 Services Gateway
  • SRX5600 Services Gateway
  • SRX5800 Services Gateway

For all services gateway models, the accessory box shipped with the device includes one cable lug that attaches the grounding cable to the services gateway chassis. The cable lug is shown in Figure 2.

Grounding Cable Lug

Before services gateway installation begins, a licensed electrician must attach the cable lug to the grounding cable that you supply. A cable with an incorrectly attached lug can damage the services gateway. The grounding cable must be no smaller than specified in Table 13, or as required by local electrical codes:

Table 13: Grounding Cable Wire Specification

Services Gateway Type

Grounding Cable Wire Specification

SRX1400 Services Gateway

14-AWG (2.1 mm2), minimum 60°C wire

SX3400 Services Gateway

10-AWG (5.3 mm2), minimum 60°C wire

SRX3600 Services Gateway

10-AWG (5.3 mm2), minimum 60°C wire

SRX5600 Services Gateway

6-AWG (13.3 mm2), minimum 60°C wire

SRX5800 Services Gateway

6-AWG (13.3 mm2), minimum 60°C wire

Note: For the SRX5800 services gateway models, we previously specified 10-AWG wire for the grounding cable. Where you have installed such grounding cables, you can safely leave them in service. However, all new installations of SRX5800 Services Gateways must have grounding cables sized according to Table 13.

If you have lost the grounding cable lug supplied with the services gateway, contact your Juniper Networks representative to obtain a replacement.

Figure 3 through Figure 7 show the locations of the chassis grounding points on the listed SRX Series Services Gateway models. We recommend that you confirm that your services gateway chassis is properly grounded as soon as practical. For full instructions on grounding the services gateway chassis, see the hardware documentation for your services gateway.
