Advanced Security and Management capabilities
The WS-C3920 Cisco Catalyst 3920 24 Ports Token Ring Switch has several advanced security and management capabilities, including:
- Access Control Lists (ACLs) for controlling network access
- Virtual LANs (VLANs) for segmenting the network
- Quality of Service (QoS) for prioritizing network traffic
- IEEE 802.1X port-based authentication for secure network access
- SNMPv3 for network management and monitoring
- Cisco FlexStack for stacking multiple switches together for centralized management
- Cisco Auto Smartports for automatically configuring switch ports based on the connected device.
Additionally, the WS-C3920 supports Token Ring, a type of computer networking protocol that enables nodes to access a shared communication medium in a controlled manner.
Power and Environmental requirements
Power requirements: The WS-C3920 Cisco Catalyst 3920 24 Ports Token Ring Switch requires a power supply of 100-240V AC, 50-60 Hz and a maximum power rating of 140W. It also supports Cisco StackPower technology, which allows for power sharing among multiple switches in a stack configuration.
Environmental requirements: The WS-C3920 Cisco Catalyst 3920 24 Ports Token Ring Switch operates within a temperature range of 32°F to 104°F (0°C to 40°C) and a relative humidity range of 10% to 90% (non-condensing). It also supports Cisco StackWise technology, which allows for stacking of up to nine switches in a single stack. The switch also has a maximum altitude of 13,123 ft (4,000m) without derating. It also has an operating temperature range of 0 to 45 degrees Celsius.
This switch is also compliant with the EMI and EMC standards, including the FCC Part 15 Class A, VCCI Class A, and CE Mark. It also meets the RoHS environmental directive.

About Refurbished Products
Different Types of Switches
Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).
The unmanaged switches offer fixed configuration on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.
The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.
The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.
Smart switches refer to switches that possess more features than those of unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.
Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.
Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
