Fully-Managed Layer 2, 10/100 Switching with Enterprise-Class Features
The 3Com® Switch 4210 is a Layer 2 entry-level 10/100 LAN switch with enterprise-class QoS, security and management features, delivering high value for network administrators looking for an economical edge device that provides simple port expansion.
This model has 48 10/100 copper Ethernet ports and two true ports 10/100/1000 with a copper
connection and two true ports for 100 or 1000MB fiber connections using mini-GBIC SFP transceivers (transceiver ordered separately). Total active ports supported is 52 at any one time.
Setting them apart from lower-end "smart managed" devices, the Switch 4210 supports an
industry-standard Command Line Interface (CLI), Web-based administration, and SNMP management.
Cluster together up to 255 devices for easy administration, with single IP management across 3Com
Enterprise switching lines. Mix clusters of Fast Ethernet and Gigabit switches including Switch 4210, 4500, 5500, 4200G, 4500G, 4800G, and 5500G models.
The Switch 4210 family comes with 3Com's limited lifetime warranty covering the unit and power
supply. Fans in PWR units are also covered. Advanced Hardware Replacement with next business day shipment is available in most regions.
- Enterprise-class, entry-level and fully-managed Layer 2, 10/100 switching at an affordable price
- Wirespeed, non-blocking performance
- Fixed configuration, plug-and-play design means the switch work right out of the box
- IEEE 802.1X network access control offers standards-based security combined with RADIUS authentication
- Clustered stacking of up to 255 devices (Switch 4210, 4200G, 4500G, 5500 and 5500G)
- SFP ports support both Gigabit and Fast Ethernet fiber connections, making network migration easier
- RADIUS Authenticated Device Access (RADA) provides authentication of attached devices via MAC address for an additional level of endpoint security
- Common operating system shared across all 3Com enterprise switches, which simplifies set-up and ongoing management
- Energy-efficient, quiet, fan-less design is ideal for the desktop or wiring closet
- Rear-mounted console port for local management
