Cisco SG112-24, Compact 24-port Gigabit switch

Unmanaged Layer 2 switch
Metal casing
fan-less (bez ventilátoru)

- Power efficiency support (EEE) for both FE and GE
1.Energy Efficient Ethernet (IEEE 802.3az)
Monitors link activity and powers down inactive links
2.Auto Power-Down / Sleep mode
Automatically turn off power on GE RJ-45 port when detecting link down
If there is no link on a port (when there is no connection or the device connected is turned off) the port(s) will enter a “sleep mode”
Resumes active mode when the switch detects the link up or device connected
3.Adjusts Power Based on Cable Length
Detects the length of connected Ethernet cable and adjusts power usage accordingly without affecting performance

Integrated in the hardware:
-Quality of Service (QoS)
Zero configuration is required by the user
Switch is able to read 802.1p tags and prioritize traffic accordingly
Automatically prioritizes traffic based on priority mapping
Uses standard 802.1p class of service (CoS) settings
Set with the same default QoS settings as the Cisco IP phones Simply connect Cisco IP phones and cameras to 110 Series switches
No configuration required based on default QoS settings

-Cable Diagnostics ( NEW )
Quickly identify and easily troubleshoot network cabling faults
When NO device on the other end of the cable and an “Open Cable” is detected: LED will light solid Amber

-Loop Detection (NEW)
Quickly identify and easily troubleshoot LOOPs in the network
Loop is created when there is more than one path between two endpoints
e.g. multiple connections between two network switches or two ports on the same switch connected to each other
A Loop creates broadcast storms - switch repeatedly rebroadcast the broadcast messages flooding the network. If the frame is sent into a looped topology, it can loop forever.
Port LED blinks AMBER if Loop is detected (This is for GE models. For functionality of FE model
