Proudly  presented  by  Ovislink,  Ov-2228/Ov-2228F/Ov2228Poe  is  a  hi-per-

formance workgroup-level or enterprise-scale switch, with 24 Fast ethernet 

ports  (24  100M  sFP  slots  for  s2228F)  plus  up  to  4  gigabit  ports.  Ovislink 

Ov-2228/Ov-2228F/Ov-2228Poe  can  connect  all  (Fast)  ethernet  devices  so 

that your investment is protected. the hi-speed connection it provides among 

workgroups can boost the capability of server clusters, and solves the bott-

leneck caused by increasing users and limited bandwidth, making network 

resources  more  available  for  your  enterprise.  More  importantly,  all  of  the 

advantages are brought to you by Ovislink at low costs and with easy mainte-

nance and the best support.

Application
 

Ovislink  Ov-2228/Ov-2228F/Ov-2228Poe  provides  desktop  Fast  ethernet  and  gigabit 

ethernet connectivity, enabling enhanced lan services for entry-level enterprise, mid-

market, and branch office networks. OvisLink OV-2228PoE also provides PoE to allow 

easy connectivity to ethernet-powered devices such as iP phones, wireless access po-

ints or iP cameras. Ovislink Ov-2228Poe complies with ieee 802.3af. Poe removes the 

need for wall power to each Poe-enabled device and eliminates the cost for additional 

electrical cable and circuits that would otherwise be necessary in iP phone, wlan de-

ployments and video surveillance.

the Ovislink Ov-2228/Ov-2228F/Ov-2228Poe provides:

• Intelligent features at the network edge, such as sophisticated access control lists  

   (acls) and enhanced security.

 

• Combo Gigabit Ethernet ports flexibility, allowing use of either a copper or a fiber  

   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 

 

• Network control and bandwidth optimization using QoS, granular rate limiting, ACLs  

   (l2-l4), 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.

 

• Automatic recognition for straight-through or cross-over cables.

 

• Lifetime warranty.

 

• Free software updates.

 - VLAN: 

   • Port-based VLAN

   • 802.1Q tagged VLAN

   • LACP and static Port trunking. Up to 3 groups  

      with up to 8 ports per group

   • Clustering. Manageability through a single  IP   

 

      address. Up to 256 switches per cluster

   • LLDP (Link Layer Discovery Protocol)

 - Control   

   • Traffic control using back pressure at half-  

      duplex and 802.3x at full-duplex

   • Port rate limit. 64K step size (100M ports) and   

      8M step size (1000M ports)    

   • Storm control. Stop sending at threshold to  

      prevent unicast/multicast/broadcast storms

   • IGMP Snooping for multicast traffic control

 - QoS 

 

   •  HOL (Head Of Line) blocking prevention

   • 802.1p tagging (8 priorities)

   • 4 dispatching queues per port
