Description
The Cisco SG350X-48P 350X Series Managed Switch is armed with 48 Gigabit Ethernet ports for connecting multiple systems to one another along with four 10 Gigabit Ethernet uplinks for creating a high-performance backbone to the network. Moreover, the SG350X switch supports stacking, which lets you manage multiple switches as a single unit. This feature accommodates up to four switches and 208 Ethernet ports.
Cisco provides useful software-based tools to help in configuration and speed of deployment, and this managed switch allows detailed control over how data travels and who has access to the network. For performance, the SG350X switch has a 130.94 Mpps transfer rate and a 176 Gb/s switching capacity. Cisco has designed 48 ports to be PoE+ compliant supporting 802.3af and 802.3at PoE network standards with a maximum PoE power budget of up to 382W. This feature allows PoE-compatible devices to run on a single connection that delivers data as well as up to 30W of power. To cool the switch, three fans are onboard and produce a maximum noise level of 52.1 dB.
The 10 Gigabit Ethernet connections on the switch can utilize existing RJ45 connectors as well as multimode and single-mode fiber connections, granting the switch a longer distance to another switch when compared to an Ethernet-based connection. Other notable features included with the switch are Layer 3 static routing for transmitting data between nodes without degrading networking performance along with IPv6 for supporting future applications without needing to upgrade networking equipment.
Multigigabit Performance
Cisco’s Multigigabit Ethernet switches offer an easy-to-deploy, budget-friendly solution that allows you to increase network speed and bandwidth using your existing cables. Cisco uses NBASE-T technology to help you get more out of your existing infrastructure. Save time and money by avoiding upgrades and extending the life of your installed cable plants.
Multigigabit Ethernet technology uses capabilities in your existing cabling infrastructure to meet bandwidth requirements and provide up to five times the performance. The technology enables intermediate data rates of 2.5 and 5 Gbps to ease the jump between traditional rates of 1 Gbps and 10 Gbps. These intermediate rates run on most installed cables and preserve older UTP wiring, which is suitable for 802.11ac wireless LAN applications.
The technology also supports Power over Ethernet (PoE) forms, including PoE+ and 60W PoE. Cisco Multigigabit Ethernet switches help you avoid having to run multiple cables between switches and access points and let your networks welcome next-generation traffic speeds and data rates.
Ease of Management and Deployment
Cisco 350 Series switches are designed to be easy to use and manage by commercial customers or the partners that serve them. They feature:
Cisco Smart Network Application (SNA) is a network-level monitoring and management tool embedded in Cisco 100 to 500 Series switches. It can discover network topology, display link status, monitor events, apply configurations, and upgrade software images across multiple switches in the network.
The FindIT Network Manager and Probe are designed to manage Cisco 100 to 500 Series switches, routers, and wireless access points. The Manager lets you proactively manage the network instead of just reacting to events.
The Cisco FindIT Network Discovery Utility works through a simple toolbar on your web browser to discover Cisco devices on the network and display basic device information, inventory, and new firmware updates to aid in the configuration and speed the deployment of Cisco Small Business products. The utility can also display serial numbers and IP addresses, to aid in configuration and deployment.
The USB port on the front panel of the switch enables easy image and configuration transfer for faster deployment or upgrade.
Simple-to-use graphical interfaces reduce the time required to deploy, troubleshoot, and manage the network and allow you to support sophisticated capabilities without increasing IT head count.
The switches also support Textview, a full Command-Line Interface (CLI) option for partners that prefer it.
Using Auto Smartports intelligence, the switch can detect a network device connected to any port and automatically configure the optimal security, Quality of Service (QoS), and availability on that port.
Cisco Discovery Protocol discovers Cisco devices and allows devices to share critical configuration information, simplifying network setup and integration.
Support for Simple Network Management Protocol (SNMP) allows you to set up and manage your switches and other Cisco devices remotely from a network management station, improving IT workflow and mass configurations.
Power over Ethernet Plus (PoE+) and 60W PoE
PoE capabilities simplify the deployment of advanced technologies by allowing you to connect and power network endpoints over a single Ethernet cable, without having to install separate power supplies. Cisco 350X Series switches are also fully backward compatible with Cisco legacy PoE protocols. Cisco 350X Series switches support the Power over Ethernet Plus (PoE+) standard (IEEE 802. at), providing up to 30 watts per port. The switches also support 60W PoE on select ports to power compact switches, high-power wireless access points, or connected lighting. The PoE power is intelligently managed in a way such that only the amount of power needed by endpoints is delivered to it and not wasted. As a result, the switches can support devices that require more power, such as 802.11ac wireless access points, video-based IP phones, surveillance cameras, and more.
Reliability and Resiliency
In a growing business where availability 24 hours a day, 7 days a week is critical, you need to assure that employees can always access the data and resources they need. In these environments, stackable switches can play an important role in eliminating downtime and improving network resiliency. For example, if a switch within a Cisco 350X Series stack fails, another switch immediately takes over, keeping your network up and running. You can also replace individual devices in the stack without taking your network offline or affecting employee productivity. The Cisco 350X Series also supports dual images, allowing you to perform software upgrades without having to take the network offline or worry about the network going down during the upgrade.
Simplified IT Operation
Cisco 350X Series switches help optimize your IT operations with built-in features that simplify and streamline day-to-day network operation:
True stacking allows you to troubleshoot, configure, and manage multiple physical switches as a single entity.
Cisco switches use common chipsets/software across all switching portfolios, so all Cisco switches within a category support the same feature set, making it easier to manage and support all switches across the network.
True Stacking
Some switches claim to support stacking but in practice support only “clustering,” meaning that each switch must still be managed and configured individually. Cisco 350X Series switches provide true stacking capability, allowing you to configure, manage, and troubleshoot all switches in a stack as a single unit, with a single IP address, for up to 4 units and a maximum of 208 Ethernet ports. A true stack delivers a unified data and control plane, in addition to management plane, providing flexibility, scalability, and ease of use because the stack of units operates as a single entity constituting all the ports of the stack members. This capability can radically reduce complexity in a growing network environment while improving the resiliency and availability of network applications. True stacking also provides other cost savings and administrative benefits through features such as cross-stack QoS, VLANs, LAGs, and port mirroring, which clustered switches can’t support.
Security
Cisco 350X Series switches provide the advanced security features you need to protect your business data and keep unauthorized users off the network:
Embedded Secure Sockets Layer (SSL) encryption protects management data traveling to and from the switch.
Extensive Access Control Lists (ACLs) restrict sensitive portions of the network to keep out unauthorized users and guard against network attacks.
Guest VLANs let you provide Internet connectivity to non-registered users while isolating critical business services from guest traffic.
Support for advanced network security applications such as IEEE 802.1X port security tightly limits access to specific segments of your network. Web-based authentication provides a consistent interface to authenticate all types of host devices and operating systems, without the complexity of deploying IEEE 802.1X clients on each endpoint.
Advanced defense mechanisms, including dynamic Address Resolution Protocol (ARP) inspection, IP Source Guard, and Dynamic Host Configuration Protocol (DHCP) snooping, detect and block deliberate network attacks. Combinations of these protocols are also referred to as IP-MAC port binding (IPMB).
IPv6 First Hop Security extends the advanced threat protection to IPv6. This comprehensive security suite includes ND inspection, RA guard, DHCPv6 guard, and neighbor binding integrity check, providing unparalleled protection against a vast range of address spoofing and man-in-the-middle attacks on IPv6 networks.
Time-based ACLs and port operation restrict access to the network during pre-designated times such as business hours.
Uniform MAC address-based security can be applied automatically to mobile users as they roam between wireless access points.
Secure Core Technology (SCT) helps ensure that the switch is able to process management traffic in the face of a Denial-of-Service (DoS) attack.
Private VLAN Edge (PVE) provides Layer 2 isolation between devices on the same VLAN.
Storm control can be applied to broadcast, multicast, and unknown unicast traffic.
Protection of management sessions occurs using RADIUS, TACACS+, and local database authentication as well as secure management sessions over SSL, SSH, and SNMPv3.
DoS attack prevention maximizes network uptime in the presence of an attack.
Networkwide Automatic Voice Deployment
Using a combination of Cisco Discovery Protocol, LLDP-MED, Auto Smartports, and Voice Services Discovery Protocol (or VSDP, a unique Cisco protocol), customers can deploy an end-to-end voice network dynamically. The switches in the network automatically converge around a single voice VLAN and QoS parameters and then propagate them out to the phones on the ports, where they are discovered. For example, automated voice VLAN capabilities let you plug any IP phone (including third-party phones) into your IP telephony network and receive an immediate dial tone. The switch automatically configures the device with the right VLAN and QoS parameters to prioritize voice traffic.
IPv6 Support
As the IP address scheme evolves to accommodate a growing number of network devices, the Cisco 350X Series can support the transition to the next generation of networking and operating systems such as Windows 7, Vista, and Linux. These switches continue to support previous-generation IPv4, allowing you to evolve to the new IPv6 standard at your own pace, and helping ensure that your current network will continue to support your business applications in the future. Cisco 350X Series switches have successfully completed rigorous IPv6 testing and have received the USGv6 and IPv6 Gold certification.
Advanced Layer 3 Traffic Management
The Cisco 350X Series switches enable traffic management capabilities to help growing businesses organize their networks more effectively and efficiently. The switches provide static LAN Layer 3 routing, allowing you to segment your network into workgroups and communicate across VLANs without degrading application performance. With these capabilities, you can boost the efficiency of your network by offloading internal traffic-handling tasks from your router and allowing it to manage primarily external traffic and security. You can minimize the need to manually configure routing devices and simplify the ongoing operation of the network.
Power Efficiency
The Cisco 350X Series integrates a variety of power-saving features across all models. These switches are designed to conserve energy by optimizing power use, which helps protects the environment and reduce your energy costs. They provide an eco-friendly network solution without compromising performance. Cisco 350X Series switches feature:
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.
Application-Specific Integrated Circuits (ASICs) use low-power 65/40-nanometer technology and low-power, high-performance ARM CPUs.
Automatic power shutoff on ports when a link is down.
LEDs that can be turned off to save power.
Embedded intelligence to adjust signal strength based on the length of the connecting cable.
