PTX10003 Site Guidelines and Requirements

 

PTX10003 Environmental Requirements and Specifications

The PTX10003 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 PTX10003 cooling system.

  • Maintain ambient airflow for normal PTX10003 operation. If the airflow is blocked or restricted, or if the intake air is too warm, the chassis might overheat, leading to the PTX10003 temperature monitor shutting down the router to protect the hardware components.

Table 1 provides the required environmental conditions for normal PTX10003 operation.

Table 1: PTX10003 Environmental Tolerances

Description

Tolerance

Altitude

No performance degradation up to 6000 feet (1828.8 meters).

Relative humidity

  • Normal operation ensured in relative humidity range of 5% through 90%, noncondensing.

  • Short-term operation ensured in relative humidity range of 5% through 93%, noncondensing.

    Note: As defined in NEBS GR-63-CORE, Issue 3, short-term events can be up to 96 hours in duration but not more than 15 days per year.

Temperature

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

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

Seismic

Complies with Zone 4 earthquake requirements per NEBS GR-3160-CORE, Issue 3.

Note

Install the PTX10003 only in restricted access areas, such as dedicated equipment rooms and equipment closets, in accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical Code, ANSI/NFPA 70.

General Site Guidelines

Efficient device operation requires proper site planning and maintenance and proper layout of the equipment, rack or cabinet (if used), 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.

PTX10003 Chassis Grounding Cable and Lug Specifications

For installations that require a separate grounding conductor to the chassis, the PTX10003 must be adequately grounded before power is connected to ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements. To ground a PTX10003, connect a grounding cable to earth ground and then attach it to the chassis grounding point.

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 transceiver 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 PTX10003 to Ground. A cable with an incorrectly attached lug can damage the PTX10003.

Before connecting the PTX10003 to earth ground, review the following information:

  • A protective earthing terminal bracket is required for connecting the PTX10003 to earth ground. This two-holed bracket attaches through the mounting bracket, providing a protective earthing terminal for the router. The accessory box shipped with the PTX10003 includes the cable lugs that attach to the terminal studs of each power supply module. The cable lugs are dual hole and sized to fit 1/4-20 UNC terminal studs at 15.86-mm (0.625-in.) center line. Screws are provided in the accessory kit to attach the protective earthing terminal bracket.

  • The grounding cable that you provide for a PTX10003 must be the same size or heavier than the input wire of each power supply. Minimum recommendations are 4 AWG (8.4 mm²) stranded wire, 60° C wire, or as permitted by local code.

PTX10003 Clearance Requirements for Airflow and Hardware Maintenance

When planning the site for a PTX10003 installation, you must allow sufficient clearance around the installed chassis (see Figure 1).

Figure 1: Clearance Requirements for Airflow and Hardware Maintenance for the PTX10003
Clearance Requirements for Airflow
and Hardware Maintenance for the PTX10003

Follow these guidelines:

  • For the cooling system to function properly, the airflow around the chassis must be unrestricted. See PTX10003 Cooling System Description and Airflow for more information about the airflow through the chassis.

  • If you are mounting a PTX10003 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 PTX10003 for service personnel to remove and install hardware components.

PTX10003 Rack Requirements

The PTX10003 chassis is designed to be installed in a four-post 19-in rack.

Rack requirements consist of:

  • Rack type

  • Mounting bracket hole spacing

  • Rack size and strength

  • Rack connection to the building structure

Table 3 provides the rack requirements and specifications for the PTX10003.

Table 3: Rack Requirements for the PTX10003

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 PTX10003 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 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 PTX10003 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 26 in. (66 cm) and 36 in. (91.4 cm) front-to-back.

  • Ensure that the rack is strong enough to support the weight of the PTX10003.

  • Ensure that the spacing of rails and adjacent racks allows for proper clearance around the PTX10003 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.
