Environmental Specifications

You must install the switch in a rack or cabinet. You must house it in a dry, clean, well-ventilated, and temperature-controlled environment.

Follow these environmental guidelines:

  • Keep the site 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 device to protect the hardware components.

The following table provides the required environmental conditions for normal switch operation of EX5200.

General Site Guidelines

Efficient device operation requires proper site planning. For the device to operate properly, you must ensure 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 the prescribed airflow guidelines to ensure that the cooling system functions properly. Ensure that the 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

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 4: 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:

  • Radio frequency interference (RFI) because of improperly installed wires.

  • Damage from lightning strikes occurring when wires exceed recommended distances or pass between buildings.

  • Damage to unshielded conductors and electronic devices as a result of electromagnetic pulses (EMPs) caused by lightning.

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 need to 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

You can mount the device on two-post racks or four-post racks.

Table 5: Rack Requirements

Rack Requirement

Guidelines

Rack Type

A U is the standard rack unit defined by the Electronic Components Industry Association (ECIA) (http://www.ecianow.org).

You can mount the device on a rack that provides bracket holes or hole patterns spaced at 1U (1.75 in. or 4.45 cm) increments and meets the size and strength requirements to support the weight.

Mounting bracket hole spacing

The holes in the mounting brackets are spaced at 1U (1.75 in. or 4.45 cm) so that the device can be mounted in any rack that provides holes spaced at that distance.

Rack size and strength

Ensure that the:

  • Rack complies with the size and strength standards of a 19-in. rack as defined by the ECIA (http://www.ecianow.org).

  • Rack rails are spaced widely enough to accommodate the external dimensions of the device chassis. Also ensure that the outer edges of the front mounting brackets extend the width of the chassis to 19 in. (48.2 cm).

  • Rack is strong enough to support the weight of the device.

  • Spacing of rails and adjacent racks provides for proper clearance around the device and rack.

Rack connection to building structure

  • Secure the rack to the building structure.

  • If your geographical area is earthquake-prone, 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

You can mount the device in a cabinet that contains a 19-in. rack.

Table 6: Cabinet Requirements and Specifications

Cabinet Requirements

Guidelines

Cabinet size and clearance

  • The minimum cabinet size is 27.7 in. (70.35 cm) between cabinet front door and cabinet rear wall. It is recommended to have minimum of 6 in. clearance from the cabinet front door and switch front panel minimum of 6 in. clearance from the cabinet rear wall and switch rear panel. Large cabinets improve airflow and reduce chances of overheating.

  • The outer edges of the front mounting brackets extend the width of the chassis to 19 in. (48.2 cm).

Cabinet airflow requirements

When you mount the device in a cabinet:

  • Ensure that ventilation through the cabinet is sufficient to prevent overheating.

  • Ensure that there is adequate cool air supply to dissipate the thermal output of the device or devices.

  • Ensure that the hot air exhaust of the chassis exits the cabinet without recirculating into the device. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top ensures 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.

  • Install the device in the cabinet in a way that maximizes the open space on the side of the chassis that has the hot air exhaust.

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

  • Ensure that the spacing of rails and adjacent cabinets is such that proper clearance exists around the device and cabinet.

  • A cabinet larger than the minimum required provides better airflow and reduces the chance of overheating.

Clearance Requirements for Hardware Maintenance for EX5200 Switches

When planning the site for installing an EX5200 switch, follow these clearance requirements

  • For the cooling system to function properly, ensure that the airflow around the chassis is unrestricted.

  • If you are mounting the switch on a rack or cabinet along with other equipment, ensure that the hot air exhaust from other equipment does not blow into the cold air intake vents of the chassis.

  • Clearance requirements for thermal performance:

    Leave at least 6 in. (15.2 cm) clearance in front of and behind the chassis for airflow.

  • Clearance requirements for hardware maintenance:

    Leave at least 24 in. (61 cm) clearance in front of and behind the switch for service personnel to remove and install hardware components.
