Description

Cisco SG300-28P 28-port Gigabit PoE Managed Switch Mtech

Cisco 28-port SG300-28P Gigabit PoE Managed Switch delivers baseline security and quality of service features needed to share network resources and connect network devices. SG300-28P has native support for IPv6 as well as the previous IPv4 standard hence  ensuring ones network is ready for the next advertisement in technology,

 

Cisco 28-port Gigabit PoE Managed Switch optimizes power hence reducing power cost and maximizes performance. The 28-port switch is PoE powered hence can be used in areas with no so good power connection, SG300-28P Switch has been rigorously tested to deliver the high availability and performance you expect from Cisco.

 

The solutions speed up file transfer times and improve slow, sluggish networks while keeping your vital business applications available and preventing costly downtime. SG300-28P Switch has twenty-six PoE Gigabit Ethernet ports.

 

This capability simplifies advanced technology deployments such as IP telephony, wireless, and IP surveillance by allowing you to connect and power network endpoints over a single Ethernet cable. With no need to install separate power supplies for IP phones or wireless access points, you can take advantage of advanced communications technologies more quickly, and at a lower cost Cisco 28-port Gigabit PoE Managed Switch Offers 2 Gigabit Ethernet combo ports, which are RJ-45 + SFP / mini-GBIC, or small form-factor pluggable / mini-Gigabit interface converter expansion slots that give you the option to add fiber-optic or Gigabit Ethernet uplink connectivity to the switch.
