EX4100-H Site Guidelines and Requirements

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.

• Ensure that the temperature inside cabinet does not cross 60° C when installing EX4100-H-24MP and EX4100-H-24F switches.

• Ensure that the temperature inside cabinet does not cross 60° C when installing the EX4100-H-24F switch.

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:

Note:

• Protect switch 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 the switch 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 Environmental 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.

Table 12 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 12: 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.

Cabinet requirements consist of:

• Cabinet size.

• Clearance requirements.

• Cabinet airflow requirements.

Table 13: Cabinet Requirements and Specifications

Cabinet Requirement	Guidelines
Cabinet depth	The minimum cabinet size is 14 in. (35.56 cm) deep for EX4100-H-12MP. The minimum cabinet size is 27 in. (69.85 cm) deep for EX4100-H-24MP and EX4100-H-24F. 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.

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 and Figure 3 for clearance requirements for airflow and hardware maintenance for the external PSUs of the EX4100-H-12MP switch.

• Figure 4 for clearance requirements for airflow and hardware maintenance for the external PSU of the EX4100-H-24MP switch.

• Figure 5 for clearance requirements for airflow and hardware maintenance for the external PSU of the EX4100-H-24F 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.
