SRX550 High Memory Services Gateway Electrical Wiring Guidelines

Table 2 describes the factors you must consider while planning the electrical wiring for the SRX550 High Memory Services Gateway at your site.

CAUTION:

It is particularly important to provide a properly grounded and shielded environment and to use electrical surge-suppression devices.

Table 2: Site Electrical Wiring Guidelines for the SRX550 High Memory Services Gateway

Site Wiring Factor

Guideline

Signaling limitations

To ensure that signaling functions optimally:

  • Install wires correctly.

    Improperly installed wires can emit radio interference.

  • Do not exceed the recommended distances or pass wires between buildings.

    The potential for damage from lightning strikes increases if wires exceed recommended distances or if wires pass between buildings.

  • Shield all conductors.

    The electromagnetic pulse (EMP) caused by lightning can damage unshielded conductors and destroy electronic devices.

Radio frequency interference (RFI)

To reduce or eliminate the emission of RFI from your site wiring:

  • Use twisted-pair cable with a good distribution of grounding conductors.

  • Use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable, if you must exceed the recommended distances.

Electromagnetic compatibility (EMC)

Provide a properly grounded and shielded environment and use electrical surge-suppression devices.

Strong sources of electromagnetic interference (EMI) can cause the following damage:

  • Destroy the signal drivers and receivers in the device.

  • Conduct power surges over the lines into the equipment, resulting in an electrical hazard.

Tip:

If your site is susceptible to problems with EMC, particularly from lightning or radio transmitters, you might want to seek expert advice.

CAUTION:

Some ports are designed for use as intrabuilding interfaces only (Type 2 or Type 4 ports, the battery return connection is to be treated as an Isolated DC return (that is, DC-I), as defined in GR-1089-CORE) and require isolation from the exposed OSP cabling. To comply the NEBS requirements and protect against lightening surges and commercial power disturbances, the intrabuilding port(s) of the device MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring. The intrabuilding port(s) of the device is suitable for connection to intrabuilding or unexposed wiring or cabling only. The addition of primary protectors is not sufficient protection to connect these interfaces metallically to OSP wiring.

SRX550 High Memory Services Gateway Grounding Specifications

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, the SRX550 High Memory Services Gateway must be adequately grounded before power is connected. You must provide a grounding lug to connect the services gateway to earth ground.

You must install the SRX550 HM in a restricted-access location and ensure that the chassis is always properly grounded. The SRX550 HM has a two-hole protective grounding terminal provided on the chassis.We recommend that you use this protective grounding terminal as the preferred method for grounding the chassis regardless of the power supply configuration. However, if additional grounding methods are available, you can also use those methods. For example, you can use the grounding wire in the AC power cord or use the grounding terminal or lug on a DC power supply. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-hole protective grounding terminal.

Warning:

Before services gateway 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 services gateway (for example, by causing a short circuit).

To ground the services gateway before connecting power, you connect the grounding cable to earth ground and then attach the lug on the cable to the chassis grounding point, using the screw.

Table 3 lists the specifications of the grounding cable used with the device.
