WS-C3650-24PD-E

Key Features:

1. 24 Ports: Like the WS-C3650-24PS-E, this switch also provides 24 Gigabit Ethernet ports (10/100/1000), which allow for high-speed connectivity for devices such as desktops, laptops, access points, and other networked devices.

2. Power over Ethernet (PoE): The -PD in the model number indicates that this switch supports Power over Ethernet Plus (PoE+). PoE+ can deliver up to 30 watts of power per port, which is ideal for devices like IP phones, security cameras, and wireless access points. This model supports a higher power output per port compared to the standard PoE found in the WS-C3650-24PS-E.

3. Layer 3 Routing: Just like the WS-C3650-24PS-E, the WS-C3650-24PD-E also has Layer 3 routing capabilities. This allows the switch to route traffic between different subnets and VLANs, eliminating the need for a separate router for internal routing tasks. It supports both static routing and dynamic routing protocols like OSPF, EIGRP, and RIP.

4. Stackable: The switch supports Cisco StackWise-160 technology, allowing you to stack multiple switches together, which increases the available bandwidth, simplifies management, and ensures network resiliency by providing failover capabilities. The switch stack operates as a single unit, making it easier to manage.

5. Advanced Security Features: The WS-C3650-24PD-E offers robust security features like 802.1X (port-based authentication), ACLs (Access Control Lists), Dynamic ARP Inspection, and IP Source Guard to protect against unauthorized access and network attacks.

6. Energy-Efficient: Cisco has incorporated Energy Efficient Ethernet (EEE) technology into the 3650 series, allowing the switch to reduce power consumption during periods of low traffic, thus improving its energy efficiency.

7. Quality of Service (QoS): The switch includes advanced QoS features, enabling you to prioritize traffic, such as voice and video, to ensure optimal performance for time-sensitive applications in an enterprise environment.

8. Cisco StackPower Technology: This model is compatible with Cisco StackPower, which provides a shared power supply for all the switches in a stack. This improves power redundancy and efficiency, as the stack shares a common pool of power.

9. Enterprise-Grade Management: The WS-C3650-24PD-E is manageable via Cisco DNA Center and Cisco Prime Infrastructure, which simplifies network monitoring, configuration, and troubleshooting.

10. Software Support: It runs Cisco IOS XE Software, which is a modular and more flexible operating system compared to traditional IOS, offering improved reliability, scalability, and ease of management.

Use Cases:

• Enterprise Networks: Ideal for medium-to-large enterprises that require high-density Ethernet connectivity, advanced Layer 3 routing, and power over Ethernet (PoE+) for connected devices like IP phones, wireless access points, and security cameras.
• Unified Communications: Its PoE+ capability is particularly beneficial in unified communications environments, where you need to provide both data and power over the same Ethernet cable for devices like IP phones and video conferencing equipment.
• Wireless Networks: The high-power PoE+ ports are perfect for supporting a large number of wireless access points in enterprise wireless network deployments.

Differences Between WS-C3650-24PS-E and WS-C3650-24PD-E:

• PoE+ vs. PoE: The main difference between the WS-C3650-24PS-E and the WS-C3650-24PD-E is the PoE+ support in the WS-C3650-24PD-E, which provides higher power per port (up to 30W), compared to the standard PoE (15.4W per port) in the WS-C3650-24PS-E. This makes the WS-C3650-24PD-E more suitable for powering devices with higher power requirements like newer IP phones, security cameras, and wireless access points.
• Power Budget: The WS-C3650-24PD-E has a higher total PoE power budget (445W), compared to the WS-C3650-24PS-E, which provides up to 370W.
