PTX10002-60C Site Guidelines and Requirements

PTX10002-60C Environmental Requirements and Specifications

The PTX10002-60C must be installed in a rack. It must be housed in a 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 vents and filters, reducing the efficiency of the PTX10002-60C cooling system.

  • Maintain ambient airflow for normal PTX10002-60C operation. If the airflow is blocked or restricted, or if the intake air is too warm, the chassis might overheat, leading to the PTX10002-60C temperature monitor shutting down the router to protect the hardware components.

Table 1 provides the required environmental conditions for normal PTX10002-60C operation.

General Site Guidelines

Efficient device operation requires proper site planning and maintenance and 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 and 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.

PTX10002-60C Chassis Grounding Cable and Lug Specifications

For installations that require a separate grounding conductor to the chassis, the PTX10002-60C must be adequately grounded before power is connected to ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements. To ground a PTX10002-60C, connect a grounding cable to earth ground and then attach it to the chassis grounding points.

Warning:

The device is a pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earthing terminal must be permanently connected to earth ground for installations that require a separate grounding conductor to the chassis.

Warning:

To comply with GR-1089 requirements, all intrabuilding copper cabling used for SFP+, QSFP+, and QSFP28 ports must be shielded and grounded at both ends.

CAUTION:

Before device installation begins, a licensed electrician must attach a cable lug to the grounding cables that you supply. See Connecting the PTX10002-60C to Ground. A cable with an incorrectly attached lug can damage the PTX10002-60C.

Before connecting the PTX10002-60C to earth ground, review the following information:

  • A protective earthing terminal bracket is required for connecting the PTX10002-60C to earth ground. This two-holed bracket attaches through the mounting bracket, providing a protective earthing terminal for the router. Screws are provided in the accessory kit to attach the protective earthing terminal bracket.

  • The grounding lug required is a Panduit LCD6-14BH-L or equivalent (provided). The grounding lug accommodates 6 AWG (13.3 mm²) stranded wire.

  • The grounding cable that you provide must be of the same size or heavier than the input wire of each power supply. the minimum recommendation is 8 AWG (8.4 mm²) stranded wire, 60° C wire, or as permitted by local code.

PTX10002-60C Clearance Requirements for Airflow and Hardware Maintenance

When planning the site for a PTX10002-60C installation, you must allow sufficient clearance around the installed chassis (see Figure 1).

Figure 1: Clearance Requirements for Airflow and Hardware Maintenance for the PTX10002-60CClearance Requirements for Airflow and Hardware Maintenance for the PTX10002-60C

Follow these guidelines:

  • For the cooling system to function properly, the airflow around the chassis must be unrestricted. See PTX10002-60C Cooling System Description and Airflow for more information about the airflow through the chassis.

  • If you are mounting a PTX10002-60C in a rack with other equipment, ensure that the exhaust from other equipment does not blow into the intake vents of the chassis.

  • You must leave at least 24 in. (61 cm) both in front of and behind the PTX10002-60C for service personnel to remove and install hardware components, you must leave adequate space at the front and back of the PTX10002-60C. NEBS GR-63 recommends that you allow at least 30 in. (76.2 cm) in front of the rack or cabinet and 24 in. (61 cm) behind the rack.

Site Electrical Wiring Guidelines

Table 3 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.
Table 3: 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 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.

Some of the problems caused by strong sources of electromagnetic interference (EMI) are:

  • 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

PTX10002-60C Rack Requirements

The PTX10002-60C chassis is designed to be installed in four-post racks.

Rack requirements consist of:

  • Rack type

  • Mounting bracket hole spacing

  • Rack size and strength

  • Rack connection to the building structure

Table 4 provides the rack requirements and specifications for the PTX10002-60C.

Table 4: Rack Requirements for the PTX10002-60C

Rack Requirement

Guidelines

Rack type: four-post

Use a four-post rack that provides bracket holes or hole patterns spaced at 1-U (1.75 in. or 4.45 cm) increments and that 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 Components Industry Association (http://www.ecianow.org/).

Mounting bracket hole spacing

The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the PTX10002-60C 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. or 23-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Components Industry Association (http://www.ecianow.org/).

  • Use a 600-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 (http://www.etsi.org).

    The horizontal spacing between the rails in a rack that complies with this standard is usually wider than the router’s mounting brackets, which 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 PTX10002-60C chassis’ external dimensions. The outer edges of the front-mounting rails extend the width to 19 in. (48.26 cm).

  • Ensure that the front and rear rack rails are spaced between 28 in. (71.1 cm) and 36 in. (91.4 cm) front-to-back.

  • Ensure that the rack is strong enough to support the weight of the PTX10002-60C.

  • Ensure that the spacing of rails and adjacent racks allows for proper clearance around the PTX10002-60C and rack.

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.
