Cleaning of Optical Connector

XG0448 Hardware Guide	Chapter 2 Installation

1.Remove the connector guard cap of optical fiber part, and check the connector end face.

If the end face is not clean, clean it with a reel type fiber cleaner.

2.Push thumb holder of a fiber cleaner and open a cap of the fiber cleaner.

3.When a cap slides and a new cleaning tape comes out, lightly apply the end face to a cleaning tape.

4.Apply the end face of the connector and rotate it (quarter turn four times).

5.Apply the end face to the cleaning tape, and move it to forward direction of a fiber cleaner.

Caution

Do not friction the end face to the cleaning tape. It will cause micro dust or scratch.

6.Take thumb holder off, and close a cap of a fiber cleaner.

7.Check the end face and continue cleaning if necessary.

Removal of Micro Dust

Remove micro dust on the optical fiber part following the method below if necessary.

1.Wipe the optical fiber part with ethanol or cleaning fluid.

2.Softly and slowly wipe the optical fiber part with cleaning fabric.

3.Wipe with a new cleaning stick in the same fashion, and dry the optical connector.

Caution

•Do not use fluid such as bleach because it will damage optical coupling.

•Use ionizer when cleaning in order to avoid the ESD damage to SFP module / SFP+ module.

•SFP module / SFP+ module cannot be washed with water. Do not use or clean SFP module / SFP+ module in a wet space such as bathroom or kitchen.

•Carefully treat SFP module as it sometimes becomes very hot.

Precautions

•Do not use alcohol, spray, and cotton swab for cleaning of optical connector other than special optical connector cleaner because dust on the end face of the optical connector plug may not be completely wiped off and more dust may adhere.

•Immediately connect optical connector to the switch after cleaning. Dust will adhere when the optical connector is left unconnected.

•Keep the connector guard cap fixed before using SFP module / SFP+ module in order to avoid contamination.

•When SFP module / SFP+ module is contaminated, check end face and clean only if necessary.

•If a lot of fluid is used, it will possibly be accumulated or leak out because SFP module / SFP+ module is not hermetically closed.

XG0448 specifications

The Fujitsu XG0448 is a high-performance network switch that stands out in the competitive landscape of data networking solutions. Designed primarily for data center environments and enterprise networks, the XG0448 offers a robust feature set that meets the demands of modern data traffic.

One of the main features of the Fujitsu XG0448 is its impressive port density. It provides 48 10-Gigabit Ethernet (10GbE) ports along with 4 additional 40-Gigabit Ethernet ports. This multi-rate capability allows network architects to design flexible and scalable network topologies tailored to their unique requirements. The ability to aggregate networks efficiently is vital in minimizing latency and maximizing throughput in high-bandwidth applications, such as cloud services and big data analytics.

The XG0448 is also built on advanced Layer 2 and Layer 3 switching technologies, offering essential functionality such as VLAN support, link aggregation, and robust Quality of Service (QoS). Its Layer 3 capabilities enable routing functionalities which facilitate optimized communication between different subnets, enhancing the overall performance and reliability of the network.

Security is a critical concern for modern networks, and the Fujitsu XG0448 addresses this with a range of security features. It includes strict access control lists (ACLs), RADIUS, and TACACS+ authentication mechanisms, as well as support for IEEE 802.1X port-based access control. These features help safeguard data while ensuring that only authorized devices can access the network.

Energy efficiency is another key characteristic of the XG0448. It is designed with power-saving technologies that allow for reduced energy consumption without compromising performance. The switch supports energy-efficient Ethernet (EEE) standards, which help lower operational costs while contributing to sustainability efforts in managing data center workloads.

In addition to its hardware capabilities, the Fujitsu XG0448 supports sophisticated management and monitoring options. The device can be managed through a web-based interface or command-line interface (CLI), providing network administrators with flexibility in managing configurations, monitoring performance metrics, and troubleshooting issues seamlessly.

In summary, the Fujitsu XG0448 network switch combines high port density, advanced switching capabilities, robust security, and energy efficiency, making it an ideal choice for organizations looking to enhance their data networking infrastructure. It adapts well to the evolving demands of enterprise IT and plays a significant role in high-performance networking scenarios.
