JRR200 Site Guidelines and Requirements

JRR200 Route Reflector Environmental Specifications

Table 1 provides the required environmental conditions for normal JRR200 Route Reflector operations. In addition, the site must be as dust-free as possible because dust can clog air intake vents, reducing the efficiency of the cooling system.

Table 1: Environmental Specifications

Description

Value

Altitude

No performance degradation up to 6,562 feet (2000 meters).

Relative humidity

Normal operation ensured in relative humidity range of 5% through 90%, non-condensing.

Temperature

  • Normal operation ensured in temperature range of 32° F through 104° F (0° C through 40° C).

  • Non-operating storage temperature in shipping container: –40° F through 158° F (–40° C through 70° C).

General Site Guidelines

Efficient device operation requires proper site planning and maintenance. It also requires proper layout of the equipment, rack or cabinet, and wiring closet.

To plan and create an acceptable operating environment for your device and prevent environmentally caused equipment failures:

  • Keep the area around the chassis free from dust and conductive material, such as metal flakes.

  • Follow prescribed airflow guidelines to ensure that the cooling system functions properly. Ensure that exhaust from other equipment does not blow into the intake vents of the device.

  • Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent damaging the 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 2 describes the factors you must consider while planning the electrical wiring at your site.

Warning:

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

Avertissement Vous devez établir un environnement protégé et convenablement mis à la terre et utiliser des dispositifs de parasurtension.

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 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) can cause:

  • 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.

Clearance Requirements for JRR200 Route Reflector Airflow and Hardware Maintenance

When planning the installation site, you need to allow sufficient clearance around the JRR200 Route Reflector. Consider the following:

  • For the cooling system to function properly, the airflow around the chassis must be unrestricted. See Figure 1.

    Figure 1: Airflow Through the ChassisAirflow Through the Chassis

  • If you are mounting the JRR200 route reflector on a rack or cabinet along with other equipment, ensure that the exhaust from other equipment does not blow into the intake vents of the chassis.

  • For service personnel to remove and install hardware components, there must be adequate space at the front and back of the JRR200 route reflector as indicated in Table 3.

Table 3 provides information about the clearance requirements for maintaining optimum airflow and the distances necessary to facilitate easy maintenance of the JRR200 route reflector.
