Ports
The Cisco CBS250-48PP-4G L3 Smart Switch is equipped with 48 ports, making it an ideal choice for businesses that require a high number of network connections. These ports allow you to connect multiple devices to the switch, such as computers, printers, IP phones, and other network devices.
Increased Connectivity
The 48 ports on the Cisco CBS250-48PP-4G L3 Smart Switch provide increased connectivity options for your network infrastructure. With a larger number of ports, you can easily connect more devices without the need for additional switches or complicated setups. This means that you can expand your network and accommodate more users and devices as your business grows, ensuring that everyone stays connected and productive.
Streamlined Network Management
Having 48 ports on a single switch simplifies network management. You can consolidate your network devices onto a single switch, reducing the need for multiple switches and cables. This not only saves space but also makes it easier to manage and troubleshoot your network. With fewer devices to monitor and maintain, you can spend less time on network administration and focus more on other important tasks.
Cost Savings
By utilizing the 48 ports on the Cisco CBS250-48PP-4G L3 Smart Switch, you can save on equipment costs. Instead of purchasing multiple switches to accommodate your network requirements, you can rely on a single switch with ample ports. This reduces the upfront investment and ongoing maintenance costs associated with managing multiple switches. Additionally, having a centralized switch reduces power consumption, further contributing to cost savings.
PoE+
The Cisco CBS250-48PP-4G L3 Smart Switch features PoE+ (Power over Ethernet) capability, providing power to connected devices through the Ethernet cables. This feature is particularly beneficial for businesses that require power to be delivered to network devices, such as IP phones, wireless access points, and security cameras.
Simplified Deployment
With PoE+ support, you can easily deploy network devices without the need for additional power outlets or wiring. The Cisco CBS250-48PP-4G L3 Smart Switch can deliver both data and power over a single Ethernet cable, eliminating the need for separate power supplies. This simplifies the installation process and reduces the amount of cabling required, resulting in a cleaner and more organized network setup.
Flexibility and Scalability
PoE+ allows for greater flexibility and scalability in your network infrastructure. With the ability to power devices directly from the switch, you can easily add or relocate devices without the limitations imposed by power outlets. This flexibility enables you to adapt to changing business needs and rearrange your network layout as required. Additionally, PoE+ supports higher power requirements, allowing you to connect a wide range of devices without compromising performance.
Enhanced Reliability
By utilizing PoE+, you can enhance the reliability of your network. Powering devices through Ethernet cables eliminates the risk of power outages affecting critical network components. In the event of a power failure, PoE+ switches can be connected to an uninterruptible power supply (UPS) to ensure continuous operation. This level of reliability is particularly important for businesses that rely heavily on their network infrastructure and cannot afford downtime.
SFP
The Cisco CBS250-48PP-4G L3 Smart Switch is equipped with one SFP (Small Form-factor Pluggable) port. This feature provides additional connectivity options for your network by allowing the use of fiber optic or copper SFP modules.
Extended Network Reach
The SFP port on the Cisco CBS250-48PP-4G L3 Smart Switch enables you to extend your network reach beyond the limitations of traditional Ethernet cables. By utilizing fiber optic SFP modules, you can establish long-distance connections, spanning several kilometers, without experiencing degradation in signal quality. This is especially useful for businesses with multiple buildings or remote locations that need to be interconnected.
High-Speed Connectivity
With the use of SFP modules, you can achieve high-speed connectivity for your network. Fiber optic SFP modules support data rates of up to 10 Gbps, providing a fast and reliable connection for bandwidth-intensive applications. Copper SFP modules, on the other hand, offer Gigabit Ethernet speeds over standard Ethernet cables, allowing for high-speed data transfer over shorter distances.
Network Redundancy
The SFP port also enables network redundancy by allowing you to establish redundant links. By connecting the Cisco CBS250-48PP-4G L3 Smart Switch to another switch or device using SFP modules, you can create a redundant path for data transmission. In the event of a link failure, traffic can be automatically redirected through the redundant link, ensuring uninterrupted network connectivity.
Gigabit Ethernet
The Cisco CBS250-48PP-4G L3 Smart Switch supports Gigabit Ethernet, providing high-speed connectivity for your network. With Gigabit Ethernet, you can achieve data transfer rates of up to 1000 Mbps, ensuring fast and efficient communication between devices.
Improved Network Performance
Gigabit Ethernet offers significantly faster data transfer speeds compared to traditional Fast Ethernet. This enhanced performance allows for quicker file transfers, smoother video streaming, and faster access to network resources. With Gigabit Ethernet, you can maximize productivity and minimize waiting times, resulting in improved overall network performance.
Enhanced Workstation Connectivity
With Gigabit Ethernet support, you can connect workstations directly to the Cisco CBS250-48PP-4G L3 Smart Switch at high speeds. This is particularly beneficial in environments where large files need to be transferred between workstations or where bandwidth-intensive applications are used. By eliminating network bottlenecks, Gigabit Ethernet ensures that workstations can fully utilize their capabilities and operate at peak performance.
Future-Proof Technology
Gigabit Ethernet provides a future-proof solution for your network infrastructure. As technology continues to advance, the demand for faster and more reliable network connections will only increase. By investing in a switch that supports Gigabit Ethernet, you can ensure that your network is ready to handle the evolving needs of your business and adapt to emerging technologies.
