Cisco WS-C3850-12X48U-S 48 Ports Ethernet Switch Refurbished

The WS-C3850-12X48U-S is a Cisco Catalyst 3850 Series switch. This series of switches is a stackable, multi-gigabit, and multigigabit Ethernet switch that provides full convergence between wired and wireless networks on a single platform.

The "12X48U" in the model number refers to the number of line card slots (12) and the number of uplink/stacking ports (48) that the switch has. The "S" at the end of the model number indicates that this is a standalone switch, as opposed to a switch that is part of a stack.

This switch has 48 Ethernet ports, which support both 10/100/1000Mbps and 10/100Mbps speeds. It also has two 10 Gbps uplink/stacking ports, which allow the switch to be stacked with other 3850 series switches to provide more ports and to form a single, virtual switch.

Cisco's Catalyst 3850 Series switches are renowned for their robustness and versatility. They are designed to meet the demands of contemporary networks, offering a combination of performance, security, and scalability.

The Cisco WS-C3850-12X48U-S belongs to the Catalyst 3850 Series, a range of switches designed to provide high-performance networking capabilities for modern enterprise needs. This particular model is equipped with 48 ports and offers advanced features for efficient network management.

• Stackable Capability: This switch can be stacked with additional compatible switches, facilitating scalability and management within larger network setups.

The inclusion of 48 ports allows for extensive connectivity options within the network infrastructure. This enables the accommodation of numerous devices, such as computers, servers, printers, and other networking devices, fostering seamless communication and data transfer.

The support for multiple speeds (10/100/1000Base-T) ensures flexibility in accommodating devices with varying bandwidth requirements. It allows the switch to adapt to different network demands, providing optimal connectivity for devices operating at different speeds.

Benefits of RJ-45 Interface

The use of RJ-45 connectors simplifies connectivity, as they are widely compatible with Ethernet-based devices. This facilitates straightforward integration of devices into the network without the need for additional adapters or converters.

The inclusion of Universal Power over Ethernet (UPoE) is crucial for powering high-power devices via Ethernet cables. This feature simplifies power management by delivering increased power levels, and supporting devices that require higher power for their operation.

The manageability of the Cisco WS-C3850-12X48U-S switch empowers network administrators to oversee and configure various aspects of the switch's operations. This includes monitoring traffic, setting up security protocols, and managing connected devices, enhancing overall network control.

The Layer 3 capabilities of this switch elevate its functionality beyond basic switching. It allows for routing functions, making decisions based on IP addresses, and enabling more sophisticated networking operations compared to Layer 2 switches.

Rack-mountable Design and 1U Form Factor

The 1U form factor makes this switch suitable for rack-mounted installations, optimizing space utilization within data centers or network cabinets. It aligns with industry standards, allowing for easy integration into existing rack setups.

The ability to stack multiple compatible switches enhances scalability within network infrastructures. This facilitates easier management of interconnected switches and allows for expansion as the network grows.

Performance and Reliability

The Cisco Catalyst 3850 series, of which the WS-C3850-12X48U-S is a part, is known for its high performance and reliability.

In terms of performance, the model can support up to 960 Gbps of switching capacity and up to 480 million packets per second (MPPs) of forwarding rate. This makes it well-suited for deployments in high-bandwidth environments, such as those that require support for large numbers of users or high-definition video streaming.

Additionally, the switch supports advanced quality of service (QoS) features, such as differentiated services code point (DSCP) and Internet Group Management Protocol (IGMP) snooping, which allow you to prioritize different types of traffic to ensure that mission-critical applications receive the bandwidth they need.

In terms of reliability, the 3850 series supports StackWise-160 technology, which allows multiple switches to be connected together and managed as a single logical device. This makes it easier to manage large numbers of switch ports, and provides redundancy and failover capabilities.

This switch also supports redundancy with its Redundant Power System (RPS) which provides power backup for the switch, which allows for continuity of the operation of connected devices in case of a power outage. This feature also provides for redundancy in the power supply, which prevents the switch from shutting down in case of a power supply failure
