EX4600 Site Guidelines and Requirements

Environmental Requirements and Specifications for EX Series Switches

The switch must be installed in a rack or cabinet housed in a dry, clean, well-ventilated, and temperature-controlled environment.

Ensure that these environmental guidelines are followed:

  • The site must be as dust-free as possible, because dust can clog air intake vents and filters, reducing the efficiency of the switch cooling system.

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

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

Note:

Install EX Series switches only in restricted 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. 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.
Table 2: 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.

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.

Rack Requirements for an EX4600 Switch

EX4600 Switches are designed to be installed on four-post racks.

Rack requirements consist of:

  • Rack type

  • Mounting bracket hole spacing

  • Rack size and strength

Table 3 provides the rack requirements and specifications for the EX4600 Switch.

Table 3: Rack Requirements for the EX4600 Switch

Rack Requirement

Guidelines

Rack type

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.

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 switch 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 Industry Association.

  • 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.

    The horizontal spacing between the rails in a rack that complies with this standard is usually wider than the device'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 switch chassis’ external dimensions. The outer edges of the front-mounting brackets extend the width to 19 in. (48.26 cm).

  • The front and rear rack rails must be spaced between 23 in. (58.5 cm) and 30.25 in. (76.8 cm) front-to-back.

  • The rack must be strong enough to support the weight of the switch.

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

Cabinet Requirements for an EX4600 Switch

You can mount the EX4600 switch in a cabinet that contains a four-post 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association.

Cabinet requirements consist of:

  • Cabinet size and clearance

  • Cabinet airflow requirements

Table 4 provides the cabinet requirements and specifications for the EX4600 switch.

Table 4: Cabinet Requirements for the EX4600 Switch

Cabinet Requirement

Guidelines

Cabinet size and clearance

The minimum cabinet size for accommodating a EX4600 switch is 36 in. (91.4 cm) deep. Large cabinets improve airflow and reduce the chance of overheating.

Cabinet airflow requirements

When you mount the switch in a cabinet, ensure that ventilation through the cabinet is sufficient to prevent overheating.

  • Ensure that the cool air supply you provide through the cabinet adequately dissipates the thermal output of the switch (or switches).

  • Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinet without recirculating into the switch. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top allows the best airflow through the chassis. If the cabinet contains a top or doors, perforations in these elements assist with removing the hot air exhaust.

  • The EX4600 fans exhaust hot air either through the vents on the port panel or through the fans and power supplies. Install the switch in the cabinet in a way that maximizes the open space on the FRU side of the chassis. This maximizes the clearance for critical airflow.

  • Route and dress all cables to minimize the blockage of airflow to and from the chassis.

  • Ensure that the spacing of rails and adjacent cabinets allows for the proper clearance around the switch and cabinet.

Clearance Requirements for Airflow and Hardware Maintenance for an EX4600 Switch

When planning the site for installing an EX4600 switch, you must allow sufficient clearance around the installed chassis (see Figure 1).

Figure 1: Clearance Requirements for Airflow and Hardware Maintenance for a EX4600 SwitchClearance Requirements for Airflow and Hardware Maintenance for a EX4600 Switch

  • For the cooling system to function properly, the airflow around the chassis must be unrestricted. See Cooling System and Airflow in an EX4600 Switch for more information about the airflow through the chassis.

  • If you are mounting an EX4600 switch in a rack or cabinet 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 EX4600 switch. For service personnel to remove and install hardware components, you must leave adequate space at the front and back of the switch. 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 or cabinet.
