Cisco CBS250-24FP4X Dubai

The Cisco CBS250-24FP4X Dubai introduces the next era of budget-friendly smart switches, seamlessly blending potent performance and reliability with a complete suite of features essential for establishing a robust business network. Managed through the Cisco Business mobile app or dashboard, this portfolio ensures a straightforward and dependable user experience. Offering flexible management options, comprehensive security capabilities, and Layer 3 static routing features surpassing those of an unmanaged or consumer-grade switch, the Cisco CBS250-24FP4X Dubai Smart Switch comes at a lower cost compared to fully managed alternatives. When in need of a dependable solution for resource sharing and connecting computers, phones, and wireless access points, the Cisco CBS250-24FP4X Dubai provides the ideal solution within a budget-friendly range.

Features

Simple configuration and management

Cisco CBS250-24FP4X Dubai is designed to be easy to deploy and use by small businesses or the partners that serve them:

  • Cisco Business Dashboard is designed to manage Cisco Business switches, routers, and wireless access points. It lets you easily customize the interface and widgets to proactively manage your network. Cisco CBS250-24FP4X Dubai supports embedded probe for Cisco Business Dashboard, eliminating the need to set up a separate hardware or virtual machine on site.
  • The Cisco Network Plug and Play solution provides a simple, secure, unified, and integrated offering to ease new device rollouts or for provisioning updates to an existing network. The solution provides a unified approach to provision Cisco routers, switches, and wireless devices with a near-zero-touch deployment experience.
  • The redesigned modern web user interfaces reduce the time required to deploy, troubleshoot, and manage the network. Configuration wizards simplify the most common configuration tasks and provide the ultimate tool for anyone to set up and manage the network.

Reliable performance

Cisco CBS250-24FP4X Dubai has been tested to deliver the high performance and reliability you would expect from a Cisco switch and help you prevent costly downtime. The switch speeds file transfer times, improve slow and sluggish networks, keep your vital business applications available, and help your employees respond more quickly to customers and each other. With a network based Cisco CBS250-24FP4X Dubai, you can address all of your business communications and connectivity needs and reduce the total cost of ownership of your technology infrastructure. The switch also supports 10 Gigabit Ethernet uplinks on select models, so you can build a high-performance and future-ready network to support your thriving business.

Layer 3 static routing

This capability allows you to segment your network into separate workgroups and communicate across VLANs without degrading application performance. As a result, you can manage internal routing with Cisco CBS250-24FP4X Dubai and dedicate your router to external traffic and security, helping your network run more efficiently.

Power over Ethernet (PoE)

Cisco Business 250 Series switches are available with PoE+ on Gigabit Ethernet models. This capability enables the deployment of IP telephony, wireless, video surveillance, and other solutions with just a single network cable, thereby eliminating the need for separate power supplies or cabling. PoE+ provides up to 30W of power per port, ideal for deployments of 802.11ac wireless access points, Pan-Tilt-Zoom (PTZ) IP cameras, videophones, and thin client devices, delivering more flexibility and investment protection.

Network security

Cisco CBS250-24FP4X Dubai provides the security and network management features you need to maintain a high level of security for your business, keep unauthorized users off the network, and protect your business data. The switch includes integrated network security to reduce the risk of a security breach, with IEEE 802.1X port security to control access to your network, Denial-of-Service (DoS) attack prevention to increase network uptime during an attack, and extensive Access Control Lists (ACLs) to protect sensitive portions of the network from unauthorized users and guard against network attacks.

Flexible and compact design

The sleek and compact design provide additional deployment flexibility, including outside wiring closet installation such as retail stores, open plan offices, and classrooms without disturbing the environment.

Energy Saver

Cisco CBS250-24FP4X Dubai conserves energy by optimizing power use, which helps protect the environment and lowers your energy costs. Power-saving features include:

  • Support for the Energy Efficient Ethernet (IEEE 802.3az) standard, which reduces energy consumption by monitoring the amount of traffic on an active link and putting the link into a sleep state during quiet periods
  • Automatic power shutoff on ports when a link is down
  • Fan-less design in most models, which reduces power consumption, increases reliability, and provides quieter operation

Peace of mind and investment protection

The Cisco CBS250-24FP4X Dubai offers the reliable performance, investment protection, and peace of mind you expect from a Cisco switch. Complementary one-year access to our Small Business Support Center for ongoing support.
