2 x 100/1000M TX ports
2 Gigabit SFP slots
1 Console port
Network manageable
Hi-performance, Network Manageable Fast Ethernet Switch
Proudly presented by OvisLink OV-2252 is the next-generation hi-perfor-
mance L2 Ethernet switch with 48 Fast Ethernet ports. It has an advanced
architecture providing 36 Gbps switch fabric, and 13.1 Mpps forwarding rate.
Its hardware wire-speed switching capability provides a powerful, multi-la-
yer solution not only for enterprises, but also for Internet Service Providers
(ISP’s) and telecom carriers.
Application
OvisLink OV-2252 provides dense Fast Ethernet, enabling enhanced LAN services for
middle-level enterprise, midmarket and ISPs.
The OvisLink OV-2252 also provides:
• Intelligent features at the network edge, such as access control lists (ACLs) and
enhanced security.
• High density port confi guration including 48 Fast Ethernet ports
• Gigabit Ethernet connectivity using both 1000BaseTX and SFP ports.
• Network control and bandwidth optimization using QoS, granular rate limiting,
ACLs, and IGMP Snooping.
• Network security through a wide range of authentication methods, and Network
Access Control based on users, ports, and MAC addresses.
• Extended manageability using CLI.
• Manageable through cluster technology allowing management using only one IP
address.
• Lifetime warranty.
• Free software updates
