The SG500X-48P-K9 48-Port PoE Gigabit Ethernet Stackable Managed Switch from Cisco features 48 Gigabit Ethernet ports, four 10 Gigabyte SFP+ Ethernet ports that includes two 10 Gigabyte Ethernet ports, and two 10 Gigabyte Ethernet and 5 Gigabyte Ethernet stacking combos. It also supports the Power over Ethernet Plus (PoE+) standard (IEEE 802.at), providing up to 30W per port. The power is managed in a way that only the amount of power the endpoint needs is delivered to it and is not wasted. The switch is equipped with 800 MHz ARM CPU, and features switching capacity of 176 Gb/s. Cisco 500X is also fully backwards compatible with IEEE 802.11af PoE and previous-generation Cisco legacy PoE protocols.

The switch provides the advanced feature set that growing businesses require, and that high-bandwidth applications and technologies demand. This switch can improve the availability of your critical applications, protect your business information, and optimize your network bandwidth to effectively deliver information and support applications. The support for the Energy Efficient Ethernet (IEEE 802.3az), reduces energy consumption by monitoring the amount of traffic on an active link and putting the link into a sleep state during quiet periods. The Cisco 500X integrates a variety of power-saving features, providing the industry's extensive energy-efficient switching portfolio.
Easy Deployment and Use
Support for Simple Network Management Protocol (SNMP) allows you to set up and manage your switch and other Cisco devices remotely from a network management station, improving IT workflow and mass configurations. The Cisco FindIT utility, which works through a simple toolbar on the user's Web browser, discovers Cisco devices in the network and displays basic information, such as serial numbers and IP addresses, to aid in configuration and deployment.
High Reliability and Resiliency
Virtual Router Redundancy Protocol (VRRP)
Simplified IT Operation
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 nonemployee 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 IPMB (IP-MAC- port binding).
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 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 using Radius, TACACS+ and local database authentication as well as secure management sessions over SSL, SSH, and SNMPv3.
DoS (Denial-of-Service) attack prevention maximizes network uptime in the presence of an attack.
High-Power Power over Ethernet Plus (PoE+)
Networkwide Automatic Voice Deployment
Advanced Layer-3 Traffic Management
The support for the Energy Efficient Ethernet (IEEE 802.3az), reduces energy consumption by monitoring the amount of traffic on an active link and putting the link into a sleep state during quiet periods. It also features application-specific integrated circuits (ASICs), which use low-power 65-nanometer technology and low power high performance ARM CPUs. The switch features automatic power shutoff on ports when a link is down, LEDs can be turned off to save power, and embedded intelligence to adjust signal strength based on the length of the connecting cable.
