SRX2300 Site Guidelines and Requirements

General Site Installation Guidelines

Take the following precautions to plan an acceptable operating environment for your SRX2300 and avoid prevent equipment failures caused due to environment:

  • Keep the area around the chassis free from dust.
  • Follow the prescribed airflow guidelines to ensure that the cooling system functions properly and that exhaust from other equipment does not blow into the intake vents of the appliance.
  • Follow the ESD procedures to avoid damaging equipment. Static discharge can cause components to fail completely or intermittently over time.
  • Install the device in a secure area, so that only authorized personnel can access the device.

Site Electrical Wiring Guidelines

Table 1 describes the factors you must consider while planning the electrical wiring at your site.


You must provide a properly grounded and shielded environment and use electrical surge-suppression devices.

Table 1: Site Electrical Wiring Guidelines
Site Wiring Factor Guidelines
Signaling limitations

If your site experiences any of the following problems, consult experts in electrical surge suppression and shielding:

  • Improperly installed wires cause radio frequency interference (RFI).

  • Damage from lightning strikes occurs when wires exceed recommended distances or pass between buildings.

  • Electromagnetic pulses (EMPs) caused by lightning can damage unshielded conductors and electronic devices.

Radio frequency interference

To reduce or eliminate RFI from your site wiring, do the following:

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

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

Electromagnetic compatibility

If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, seek expert advice.

Strong sources of electromagnetic interference (EMI) may cause the following problems:

  • Destruction of the signal drivers and receivers in the device

  • Electrical hazards as a result of power surges conducted over the lines into the equipment

Environmental Requirements and Specifications for SRX2300

The SRX2300 must be housed in dry, clean, well-ventilated, and temperature-controlled environment. Follow these environmental guidelines:

  • Ensure that the site is dust-free because dust can clog the air intake vent. This reduces the efficiency of the cooling system.

  • Maintain ambient airflow for normal operation. If the airflow is blocked or restricted, or if the intake air is too warm, the appliance might overheat.

The following table lists the environmental specifications for the SRX2300:

Clearance Requirements for Hardware Maintenance of SRX2300

When planning the site for installing an SRX2300, ensure that there is sufficient space around the installed chassis.

  • For the operating temperature of the SRX2300 to be optimal, the airflow around the chassis must be unrestricted.

  • For service personnel to remove and to install hardware components, and to accommodate the interface and power cable bend radius, there must be adequate space at the front and rear of the appliance. Allow at least 24 in. (61 cm) of space both at the front and the rear of the appliance.

  • If you are mounting the appliance in a rack with other equipment, or if you are placing it on the desktop near other equipment, ensure that the exhaust from other equipment does not blow into the intake vents of the chassis.

Rack Requirements for SRX2300

You can mount the SRX2300 on four-post racks. The rack mounting kit is shipped with the device. Table 3 provides the rack requirements and specifications for SRX2300.

Table 3: Rack Requirements and Specifications
Rack Requirement Guidelines
Rack type

Use a four-post rack with bracket holes or hole patterns spaced at 1 U increments (1.75 in. or 4.45 cm). Ensure that the rack meets the size and strength requirements to support the weight.

A U is the standard rack unit as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Industry Association.

Mounting bracket hole spacing Ensure that the holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm) so that the device can be mounted in any rack that provides holes that are spaced at that distance.

The front rack opening between the flanges must be 450 mm wide + 2 mm (17.75 in. + 0.08 in.).

Rack size and strength
  • Ensure that the rack complies with the standards for a 19 in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Industry Association.

  • Use an 800 mm rack as defined in the four-part Equipment Engineering (EE) European telecommunications standard for equipment practice (document numbers ETS 300 119-1 through 119-4) published by the European Telecommunications Standards Institute (

    The horizontal spacing between the rails in a rack compliant with this standard is usually wider than the device's mounting brackets. The mounting brackets measure 19 in. (48.26 cm) from outer edge to outer edge. Use approved wing devices to narrow the opening between the rails as required.

  • Ensure that the rack rails are spaced widely enough to accommodate the external dimensions of the device chassis. The outer edges of the front-mounting brackets extend the width to 19 in. (48.26 cm).

  • Ensure that for four-post installations, the front and rear rack rails are spaced between 23.6 in. (60 cm) and 36 in. (91.4 cm) front-to-back.

  • Ensure that the rack is strong enough to support the weight of the device. A fully-configured SRX2300 with 2 PSUs weighs about 19.12 lb (8.5 kg).

  • Ensure that the spacing of rails and adjacent racks allows for proper clearance around the device and rack.

Rack connection to building structure
  • Secure the rack to the building structure.

  • If earthquakes occur in your geographical area, secure the rack to the floor.

  • Secure the rack to the ceiling brackets and to wall or floor brackets for maximum stability.
