Environmental Requirements and Specifications for EX4100-H-12T Switches

You must install the switch/device/chassis (switch or switch along with external PSU) in a cabinet. You must house it in a dry, clean, well-ventilated, and temperature-controlled environment.

Note:

Switch, device, chassis, and switch chassis all refer to the switch or the switch along with its external PSU(s).

Follow these environmental guidelines:

  • Ensure that the site is as dust-free as possible. 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. If the switch overheats, the switch temperature monitor may shut down the switch to protect the hardware components.

The following are the required environmental conditions for normal switch operation of EX4100-H-12T switches.

  • Switch: EX4100-H-12T

  • Altitude: No performance degradation up to 15,000 feet (4572 meters)

  • Relative humidity: Normal operation ensured in relative humidity range of 5% through 95%, noncondensing

  • Seismic tolerance: Tested for Zone 4 earthquake safety.

  • Temperature:

    • Normal operation ensured in sealed enclosure in temperature range of -40 °F through 140 °F (-40 °C to 60 °C) , up to 15000 feet.

    • Normal operation ensured in ventilated enclosure in temperature range of -40 °F through 158 °F (-40 °C to 70 °C) , up to 15000 feet.

    • Normal operation ensured in blower equipped enclosure in temperature range of -40 °F through 167 °F (-40 °C to 75 °C) , up to 15000 feet.

    • Non-operating storage temperature in shipping container: -40 °F through 185 °F (–40 °C through 85 °C).

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

The following table 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.
Warning:

The intra-building ports of the equipment or subassembly must use shielded intra-building cabling/wiring that is grounded at both ends.
Table 5: 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 6: Rack Requirements and Specifications

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 for EX4100-H-12T Switches

Cabinet requirements consist of:

  • Cabinet size.

  • Clearance requirements.

  • Cabinet airflow requirements.

Table 7: Cabinet Requirements and Specifications

Cabinet Requirement

Guidelines

Cabinet depth

  • The minimum cabinet size is 14 in. (35.56 cm) deep for EX4100-H-12T.

  • Large cabinets improve airflow and reduce chances of overheating.

Cabinet width

  • The outer edges of the front mounting brackets extend the width of the switch 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, as follows:

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

  • Ensure that the hot air exhaust of the switch chassis exits the cabinet without recirculating into the device.

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

  • Route and secure all cables to minimize the blockage of airflow to and from the switch 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 Airflow and Hardware Maintenance for EX4100-H-12T Switches

When planning the site for installing an EX4100-H-12T switch, you must allow sufficient clearance around the installed switch.

Figure 1: Clearance Requirements for Thermal Performance (Airflow) and Hardware Maintenance for the EX4100-H-12T Switch Clearance Requirements for Thermal Performance (Airflow) and Hardware Maintenance for the EX4100-H-12T Switch

If you are mounting the switch in a cabinet with other equipment ensure that the exhaust from other equipment does not blow into the intake vents of the switch chassis. Ensure temperature inside the enclosure conform to environmental specification. See Environment Guidelines.

  • Clearance requirements for thermal performance

    • Leave at least 2 in around the device except mounting side for proper airflow around the units and the fin surface.

  • Clearance requirements for hardware maintenance

    • Leave at least 24 in around the device except mounting side for proper airflow around the units and the fin surface.
