PTX10008 Environmental Requirements and Specifications

The PTX10008 router must be installed in a four-post 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 router cooling system.

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

Table 2 provides the required environmental conditions for normal router operation.

Table 2: PTX10008 Environmental Tolerances

Description

Tolerance

Altitude

No performance degradation up to 6562 feet (2000 meters).

Relative humidity

  • 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 through 104° F (0° C through 40° C).

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

  • Short-term operation: 23° F to 155° F (—5° C to + 50° C).

    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.

Seismic

Designed to comply with Zone 4 earthquake requirements according to NEBS GR-63-CORE, Issue 3.

Note

Install PTX10008 routers 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.

PTX10008 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.

PTX10008 Site Electrical Wiring Guidelines

Table 3 describes the factors you must consider while planning the electrical wiring at your site.

Caution

It is particularly important to provide a properly grounded and shielded environment and to use electrical surge-suppression devices.

Table 3: Site Electrical Wiring Guidelines

Site Wiring Factor

Guideline

Signaling limitations

To ensure that signaling functions optimally:

  • Install wires correctly.

    Improperly installed wires can emit radio interference.

  • Do not exceed the recommended distances or pass wires between buildings.

    The potential for damage from lightning strikes increases if wires exceed recommended distances or if wires pass between buildings.

  • Shield all conductors.

    The electromagnetic pulse (EMP) caused by lightning can damage unshielded conductors and destroy electronic devices.

Radio frequency interference (RFI)

To reduce or eliminate the emission of RFI from your site wiring:

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

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

Electromagnetic compatibility (EMC)

Provide a properly grounded and shielded environment and use electrical surge-suppression devices.

Strong sources of electromagnetic interference (EMI) can cause the following damage:

  • 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.

Tip: If your site is susceptible to problems with EMC, particularly from lightning or radio transmitters, you might want to seek expert advice.

Warning

The intrabuilding port(s) of the equipment or subassembly is suitable for connection to intrabuilding or unexposed wiring or cabling only. The intrabuilding port(s) of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intrabuilding interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE), and require isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient protection to connect these interfaces metallically to OSP wiring

PTX10008 Rack Requirements

The PTX10008 router chassis are designed to be installed in four-post racks.

Rack requirements consist of:

  • Rack type

  • Rack mount kit hole spacing

  • Rack size and strength

  • Rack connection to the building structure

Table 4 provides the rack requirements and specifications for the PTX10008 router.

Table 4: Rack Requirements for the PTX10008

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 Industry Association.

You can stack three PTX10008 routers at the bottom of the four-post rack if:

  • The rack is 42 U or greater.

  • The rack meets the strength requirements to support the weight.

  • The facility can provide adequate power and cooling.

Rack mount kit hole spacing

The holes in the rack mount kit are spaced at 1 U (1.75 in. or 4.45 cm), so that the router 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. wide rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Industry Association.

  • Use one of the standard rack lengths 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).

    • 23.62 in. (600 mm)

    • 30.0 in. (762 mm)

    • 31.5 in. (800 mm)

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

  • Ensure that the rack is strong enough to support the weight of the router and cabling.

  • Ensure that the spacing of rails and adjacent racks allows for proper clearance around the router and rack. See PTX10008 Clearance Requirements for Airflow and Hardware Maintenance.

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 as well as wall or floor for maximum stability.

PTX10008 Clearance Requirements for Airflow and Hardware Maintenance

When planning the site for a PTX10008 router installation, you must allow sufficient clearance around the installed chassis for cooling and maintenance. See Figure 1 and Figure 2 for a top view of clearance for the PTX10008.

Clearance Requirements for
Airflow and Hardware Maintenance for a PTX10008 with JNP10008-FAN2

Follow these guidelines:

  • For the cooling system to function properly, the airflow around the chassis must be unrestricted. See PTX10008 Cooling System and Airflow for more information about the airflow through the chassis.

  • If you are mounting a PTX10008 in a rack with other equipment, ensure that the exhaust from other equipment does not blow into the intake vents of the chassis.

  • Leave at least 24 in. (61 cm) both in front of and behind the PTX10008 for service personnel to remove and install hardware components. To be NEBS GR-63 compliant, allow at least 30 in. (76.2 cm) in front of the rack and 24 in. (61 cm) behind the rack.

PTX10008 Chassis Physical Specifications

The PTX10008 modular chassis is a rigid sheet-metal structure that houses the other router components. You can mount up to three PTX10008 routers in a standard 19-in. 4-post rack (42 U) rack provided the rack can handle the combined weight and there is adequate power and cooling. Table 5 summarizes the physical specifications of the chassis. See Figure 3.
