WS-C3650-48PD-L

Key Features:

1. 48 Ports of Gigabit Ethernet:

   • This switch has 48 Gigabit Ethernet ports (10/100/1000 Mbps), providing ample connectivity options for various network devices like computers, printers, and IP phones.
   • Gigabit Ethernet enables faster data transmission speeds, which is ideal for modern networks with high-bandwidth applications.

2. Power over Ethernet Plus (PoE+):

   • The PoE+ functionality provides up to 30 watts of power per port (compared to standard PoE’s 15.4W per port).
   • This makes the WS-C3650-48PD-L ideal for powering devices like IP phones, wireless access points, security cameras, and other PoE-enabled devices over the same Ethernet cable.
   • With 48 ports supporting PoE+, the switch offers a total PoE budget of 740W (depending on the configuration), making it suitable for large deployments where multiple devices need to be powered directly from the switch.

3. Layer 3 Routing:

   • The WS-C3650-48PD-L supports Layer 3 routing, which allows it to route traffic between different VLANs or subnets without the need for a separate router.
   • It supports both static routing and dynamic routing protocols such as OSPF, EIGRP, and RIP.
   • This makes the switch suitable for both enterprise access and distribution layers in a network.

4. Cisco StackWise-160:

   • The StackWise-160 technology enables you to stack up to 9 switches in a single unified stack.
   • The stacked switches act as a single unit, which simplifies management, increases bandwidth, and provides redundancy in case of hardware failure.
   • This technology supports up to 160 Gbps of stacked bandwidth, allowing for efficient, high-performance inter-switch communication.

5. Redundancy and High Availability:

   • The switch supports features like StackPower, allowing multiple switches in a stack to share a common power supply.
   • This helps provide power redundancy and makes the system more resilient to power failures.

6. Advanced Security Features:

   • Cisco’s Catalyst 3650 Series switches offer robust security features such as:
     • 802.1X authentication (for secure network access control)
     • Access Control Lists (ACLs) to define what traffic can or cannot pass through the network
     • IP Source Guard to protect against IP spoofing
     • Dynamic ARP Inspection (DAI) to prevent ARP-based attacks
   • These features are essential for ensuring the network is protected against unauthorized access and attacks.

7. Quality of Service (QoS):

   • The WS-C3650-48PD-L supports advanced Quality of Service (QoS), allowing you to prioritize specific types of traffic, such as voice or video, to ensure optimal performance for critical applications in your network.
   • It includes features such as traffic shaping, classification, and marking, which help manage and optimize network traffic.

8. Energy Efficiency:

   • Cisco incorporates Energy Efficient Ethernet (EEE) technology, which reduces power consumption during periods of low traffic, helping to lower operational costs.
   • The switch is also designed to meet various energy efficiency standards, making it suitable for organizations aiming to reduce their environmental footprint.

9. Management and Monitoring:

   • The WS-C3650-48PD-L can be managed through Cisco DNA Center, Cisco Prime Infrastructure, or the traditional command-line interface (CLI).
   • It also supports Simple Network Management Protocol (SNMP) for monitoring network devices and performance, allowing network administrators to easily track usage and troubleshoot issues.

Specifications:

• Ports: 48 Gigabit Ethernet ports (10/100/1000)
• PoE+: Up to 740W of PoE power (with a 30W power budget per port)
• Switching Capacity: 128 Gbps (full-duplex)
• Forwarding Rate: 95.23 Mpps (Million packets per second)
• Layer 3 Features: Supports static routing and dynamic routing protocols like OSPF, EIGRP, and RIP
• Stacking Technology: Cisco StackWise-160 (supports up to 9 switches)
• Redundancy: Supports StackPower for shared power redundancy
• Energy-Efficient: Supports Energy Efficient Ethernet (EEE)
• Dimensions: 1.73 x 17.5 x 10.5 inches (44 x 445 x 267 mm)
• Weight: Approximately 7.6 kg (16.75 lbs)
• Software: Runs on Cisco IOS XE, which is a modular, flexible operating system offering enhanced features and scalability.

Use Cases:

• Enterprise Networks: The WS-C3650-48PD-L is an excellent choice for large enterprise networks that require high-density switching, PoE support, and routing capabilities. It can handle a wide range of devices such as phones, access points, cameras, and other networked devices.
• Unified Communications: Ideal for environments that rely on VoIP (Voice over IP) and IP video surveillance solutions, as it can provide both data and power to these devices via PoE+.
• Campus Networks: The switch is suitable for deployment in campus networks where high-speed, reliable, and scalable switching is needed across multiple buildings or floors.
• Data Center and Edge Applications: The Layer 3 routing and high PoE capacity make this switch a good option for data center edge deployments and for interconnecting distribution layers.

Differences from Other Models:

• The -L suffix in the model number indicates that the WS-C3650-48PD-L is running the LAN Base software image. The LAN Base image offers essential Layer 2 and limited Layer 3 features, such as static routing, basic security, and network management capabilities. This is different from models with the IP Base or IP Services images, which offer more advanced routing and services (e.g., OSPF, EIGRP, advanced security).
