2.2. Safety Information
Before installation:
Read this manual completely and gather all information available on the product. Make sure it is fully understood. Check that your application does not exceed the safe operating specifications for the product.

SAFETY DURING INSTALLATION
The product must be installed and operated by qualified service personnel and installed into an apparatus cabinet or similar, where access is restricted to service personnel only.
Refer to chapter Compliance Information to see the required level of qualified service personnel according to safety standards.
Before energizing and connecting communication cables to the product, ensure a protective earthing conductor is first connected to the protective earthing terminal (only valid for metallic housings). Westeros recommends a cross- sectional area of at least 4 mm
Upon removal of the product, disconnect the product from the power supply and all other communication ports before disconnecting the protective earthing conductor.

HAZARDOUS VOLTAGE
Do not open an energized product. Hazardous voltage may occur when connected to a power supply.

PROTECTIVE FUSE
The power supply wiring must be sufficiently fused.
It must be possible to disconnect manually from the power supply. Ensure compliance to national installation regulations.
POWER SUPPLY CONNECTION
There are safety regulations governing the power source that can be used in conjunction with the product. Refer to chapter Interface Specifications.
REDUCE THE RISK OF FIRE
To reduce the risk of fire, use only telecommunication line cords with a cable diameter of AWG 26 or larger. Regarding power cable dimensions, see chapter Interface Specifications.

CLASS 1 LASER PRODUCT
Do not look directly into a fiber optical port or any connected fiber, although the product is designed to meet the Class 1 Laser regulations and complies with 21 CFR 1040.10 and 1040.11.
HANDLING OF SFP TRANSCEIVERS SFP
transceivers are supplied with plugs to avoid contamination inside the optical port. They are very sensitive to dust and dirt. If the fiber optic cable is disconnected from the product, a protective plug must be used on the transmitter/receiver. The protective plug must be kept on during transportation. The fiber optic cable must be handled the same way.

CORROSIVE GASES
If the product is placed in a corrosive environment, it is important that all unused connector sockets are protected with a suitable plug, in order to avoid corrosion attacks on the gold plated connector pins.

ELECTROSTATIC DISCHARGE (ESD )
Prevent electrostatic discharge damage to internal electronic parts by discharging your body to a grounding point (e.g. use a wrist strap).

2.3. Care Recommendations
Follow the care recommendations below to maintain full operation of the product and to fulfill the warranty obligations:

•  Do not drop, knock or shake the product. Rough handling above the specification may cause damage to internal circuit boards.
• Use a dry or slightly water-damp cloth to clean the product. Do not use harsh chemicals, cleaning solvents or strong detergents.
• Do not paint the product. Paint can clog the product and prevent proper operation.

If the product is used in a manner not according to specification, the protection provided by the equipment may be impaired.
If the product is not working properly, contact the place of purchase, the nearest Westeros distributor office or Westeros technical support.

Product Description

3.1. Product Description The RedFox-7528 Industrial Ethernet switch is designed to be a workhorse, providing performance and robustness today and for years to come. In today’s world, many applications combine data, voice, and video, and as a result, high performance and reliability are required. The RedFox-7528 high performance industrial Ethernet switches provide an ideal solution for these large-scale industrial networks.
RedFox-7528 is designed for 19” cabinets according to the ETSI standard, which makes it suitable for use in control room networks as well as for cabinets installed along railway trackside installations. In addition to the ultra- rugged IP40 finless all metal housing, it is equipped with configurable I/O fault contacts, which makes it ideal for easy installation and monitoring in industrial applications.
To ensure long service life and market leading MTBF, only industrial grade components are used. In addition, the switches can withstand constant vibration, extreme temperatures and demanding electrical environments. RedFox-7528  has been tested both by Westeros and external test labs to meet many standards regarding EMC, isolation, vibration and shock, all to the highest levels suitable for heavy industrial environments and rail trackside applications.
Powered by Woe’s, the Westeros network operating system, the switches are flexible, feature-rich as well as easy to install and configure. Woe’s has been developed to allow cross-platform and future-proof solutions and can deliver  resilient and flexible networks, e.g. the FRNT ring protocol with very fast failover.
Ensuring the security of industrial data communication networks is of paramount importance, especially with the nature of cyberattacks becoming increasingly sophisticated. To reduce risk and increase cyberresilience, RedFox-7528 has  an extensive suite of advanced cybersecurity features. These can be used to build networks in compliance with the IEC 62443 standard, which defines technical security requirements for data communication network components.

3.4.5. SFP Transceivers
The product supports UL and IEC certified transceivers only. See Westeros’s modular transceivers datasheets for supported SFP and SFP+ transceivers, which can be downloaded from the product support pages at www.westermo.com/support/productsupport.
Each SFP slot can hold one SFP transceiver. See “Transceiver User Guide 6100-0000” for transceiver handling instructions, which also can be downloaded from the product support pages at
www.westermo.com/support/product-support.
In the event of contamination, the optical connectors in the SFP transceivers should only be cleaned by the use of forced nitrogen and some kind of cleaning stick. Recommended cleaning fluids are methyl-, ethyl-, isopropyl- or isobutyl alcohol, hexane or naphtha.
HANDLING OF SFP TRANSCEIVERS
SFP transceivers are supplied with plugs to avoid contamination inside the optical port. They are very sensitive to dust and dirt. If the fiber optic cable is disconnected from the product, a protective plug must be used on the transmitter/receiver. The protective plug must be kept on during transportation. The fiber optic cable must be handled the same way.
