EX4100-H Site Guidelines and Requirements

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

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 device to protect the hardware components.

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

• Switch: All EX4100-H switch models

• 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).

Note:

Install the EX4100-H switch only in restricted areas, such as dedicated equipment rooms and equipment closets. Install the switch in accordance with Articles of the National Electrical Code, ANSI/NFPA 70.

Note:

EX4100-H-12MP switch must be installed in cabinet or enclosure whether the switch is installed outdoor or indoor.

Table 2: Environmental guidelines

Requirement	EX4100-H-12MP
Operational temperature range upto 15000 feet altitude Sealed cabinet (0 LFM): -40deg C to +60 deg C Vented cabinet (40 LFM): -40 deg C to 70 deg C Blower equipped cabinet (200LFM) : -40 deg C to +75 deg C	Supported
Storage temperature range - -40 deg C to +85 deg C Storage temperature range altitude upto 15000 feet	Supported
Altitude - upto 15000 feet without temperature derating.	Supported

Note:

• Protect system from moisture, salt fog, outdoor containments when deployed in vented cabinets in outdoor location and in non-office indoor environment locations.

• Corrosion: components such as RJ 45 connector, SFP Cage, EMI fingers, fasteners, chassis- should not corrode due to salt fog when system is in vented outdoor cabinet.

• When the switch installed in an enclosure or cabinet, the temperature within the enclosure is greater than room temperature outside the enclosure. Ensure temperature inside the enclosure conforms to device specification detailed in Table 2.

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 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.

Table 3 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 3: 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 occuring when wires exceed recommended distances or pass between buildings Electromagnetic pulses (EMPs) caused by lightning damaging 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. 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.

Cabinet requirements consist of:

• Cabinet size.

• Clearance requirements.

• Cabinet airflow requirements.

Table 4: Cabinet Requirements and Specifications

Cabinet Requirement	Guidelines
Cabinet size	The minimum cabinet size is 14 in. (35.56 cm) deep. Large cabinets improve airflow and reduce chances of overheating.
Cabinet clearance	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, 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 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 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.

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

See:

• Figure 1 for clearance requirements for airflow and hardware maintenance for EX4100-H-12MP switches.

• Figure 2 for clearance requirements for airflow and hardware maintenance for the external PSU of the EX4100-H-12MP 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 chassis. Ensure temperature inside the enclosure conform to environmental specification. See Environment Guidelines Table 2.

• 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.

If you are mounting the PSU in a cabinet with other equipment ensure that the exhaust from other equipment does not blow into the intake vents of the chassis. Ensure temperature inside the enclosure conform to environmental specification. See Table 2.

• 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.

EX4100-H-12MP switch must be installed in cabinet or enclosure whether the switch is installed outdoor or indoor.
