SSR130 Site Guidelines and Requirements

General Site Installation Guidelines

The following precautions help you plan an acceptable operating environment for your SSR130 appliance and avoid environmentally caused equipment failures:

  • Keep the area around the chassis free from dust.

  • Follow 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 appliance in a secure area, so that only authorized personnel can access the appliance.

Site Electrical Wiring Guidelines

Table 1 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.

Environmental Requirements and Specifications for SSR130

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

  • The site must be as dust-free as possible, because dust can clog air intake vent, reducing 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.

Table 3 lists the environmental conditions required for normal operation.

Altitude

No performance degradation up to 6,562 feet (2,000 meters)

Clearance Requirements for Hardware Maintenance of SSR130

When planning the site for installing an SSR130, you must allow sufficient clearance around the installed chassis.

  • For the operating temperature of the SSR130 to be optimal, the airflow around the chassis must be unrestricted.

  • For service personnel to remove and 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.

Requirements for Mounting an SSR130 Appliance on a Desktop or Other Level Surface

You can install the SSR130 appliance on a desktop or other such level surface. When choosing a location, allow at least 6 in. (15.2 cm) of clearance between the front and back of the chassis and adjacent equipment or walls. Ensure that the desktop or other level surface on which the appliance is installed is stable and securely supported.

Rack Requirements for SSR130

You can mount the SSR130 on two-post racks. You must order the rack mounting kit (part number: SSR100-RMK) separately. Table 4 provides the rack requirements and specifications for SSR130.

Table 4: Rack Requirements and Specifications

Rack Requirement

Guidelines

Rack type

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

A U is the standard rack unit 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 appliance can be mounted in any rack that provides holes spaced at that distance.

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.

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

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

Rack connection to building structure

  • Secure the rack to the building structure.

  • If earthquakes are a possibility in your geographical area, secure the rack to the floor.

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