2 x 100/1000M Ethernet Expansion Slots
Supports up to 4 Gigabit Ports
1 Console port
Network manageable
Hi-performance, Network Manageable Fast Ethernet Switch
Proudly presented by OvisLink OV-2252S 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-2252S provides dense Fast Ethernet, enabling enhanced LAN services for
middle-level enterprise, midmarket and ISPs.
The OvisLink OV-2252S 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
• Combo Gigabit Ethernet ports fl exibility, allowing use of either a copper or a fi ber
uplink. The combo port has one 10/100/1000 Ethernet port and one Small Form-
Factor Pluggable (SFP)-based Gigabit Ethernet port, with one port active at a time
(using expansion slot).
• 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.
Features:
- VLAN:
• Port-based VLAN

- Control
• Traffi c control using back pressure at half-
duplex and 802.3x at full-duplex
• Port rate limit. 64K step size
• Storm control. Stop sending at threshold to
prevent unicast/multicast/broadcast storms

• RMON groups 1,2,3,9
• CLI (Telnet, console)
• SSH
• Web interface
• NTP (Network Time Protocol) to provide an
accurate and consistent timestamp to all
intranet switches.
• Port mirroring based on traffi c fl ow
(ingress/egress)
• Software and confi guration upload/download
via TFTP/FTP
