They also support Layer 2 to Layer 4 Quality of Service (QoS), bandwidth control, and IGMP/MLD Snooping. With the link aggregation of supporting ports, these switches allow for high-speed trunking, combining multiple fiber ports, and support fail-over. **Enhanced Security** The GS-5220-16S8C and GS-5220-16S8CR offer a comprehensive Layer 2 to Layer 4 Access Control List (ACL) for securing your network. You can use it to restrict network access by denying packets based on source and destination IP addresses, TCP/UDP ports, or defined network applications. The protection mechanism also includes 802.1x port-based and MAC-based user and device authentication, ensuring user privacy with the private VLAN function. Furthermore, these switches provide DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection functions to prevent IP snooping attacks and discard ARP packets with invalid MAC addresses. The network administrators can now construct highly-secured corporate networks with considerably less time and effort than before. **Efficient and Secure Management** The GS-5220-16S8C and GS-5220-16S8CR managed switches are equipped with various management interfaces, including console, Web, and SNMP. These interfaces provide an easy-to-use platform-independent facility for managing and configuring the switches. The GS-5220-16S8C and GS-5220-16S8CR support the standard Simple Network Management Protocol (SNMP), allowing management via any software that supports the protocol. For text-based management, the switches can be accessed via Telnet. Additionally, the console port with a Cisco-like command line interface makes it easier for users to manage the switches. Furthermore, the GS-5220-16S8C and GS-5220-16S8CR offer secure remote management by supporting SSH, SSL, and SNMPv3 connections. These connections encrypt the packet content at each session, ensuring a secure and reliable management experience. **Hardware Specifications** **Copper Ports** The switches have 8 10/100/1000Base-T RJ-45 ports, which are auto-MDI/MDI-X ports shared with ports 1 to 8. Additionally, there are 24 SFP/mini-GBIC slots for 100/1000Base-X dual-speed interfaces. **Console Port** There is a 1 x RS-232 to RJ45 serial port for console access, with the following settings: 115200, 8, N, and 1. **Switch Architecture** The switches are store-and-forward switches with a non-blocking fabric architecture. They offer a throughput of 35.7Mpps@64Bytes, an address table of 16K entries with automatic source address learning and ageing, and a shared data buffer of 16M bits. The switches also support IEEE 802.3x pause frames for full-duplex operation and back pressure for half-duplex operation. They allow for jumbo frames of up to 10K bytes and have a reset button that resets the system in less than 5 seconds or factory default settings in more than 5 seconds. **LED Indicators** The switches have various LED indicators for different functions, including system power (green), DC power (green) for the GS-5220-16S8CR only, fault (red), and fan (red). The 10/100/1000T RJ45 interfaces (ports 1 to 8) have LED indicators for 1000Mbps link/activity (green) and 10/100Mbps link/activity (orange). Similarly, the 100/1000Mbps SFP interfaces (ports 1 to 24) have LED indicators for 1000Mbps link/activity (green) and 100Mbps link/activity (orange). **Power Requirements** The GS-5220-16S8C requires 100 to 240V AC power at 50/60Hz, while the GS-5220-16S8CR requires the same range but also needs 48V DC power at 0.6A. The power consumption of the switches is 45 watts or 153 BTUs (maximum). **ESD Protection** The switches have ESD protection of 6KV DC. **Layer 2 Functions** The switches offer various layer 2 functions, including port configuration, auto-negotiation for 10/100/1000Mbps full and half-duplex mode selection, flow control disable/enable, and port status display for each port’s speed, duplex mode, link status, flow control status, auto-negotiation status, and trunk status.
