Welcome

Thank you for choosing the Cisco SG 100D-08 Unmanaged Switch, a

Cisco Small Business network communications device.

This guide will familiarize you with the layout of the unmanaged switch and

describe how to deploy the device in your network. For additional

information, see www.cisco.com/smb.

Network Speed and Auto MDI/MDI-X Detection

All ports support network speed auto-negotiation and auto MDI/MDI-X

crossover detection. Network speed auto-negotiation automatically

selects the best connection speed and mode (half- or full-duplex) for

communicating with attached devices. Auto MDI/MDI-X crossover

detection automatically adjusts for the cable type (straight-through or

crossover) used to connect the unmanaged switch to other devices.

Green Energy Savings Technology

Green Ethernet Technology saves energy by entering sleep mode on a

Cisco SG 100D-08 port while there is no connection or the device

connected to that switch port is turned off.

Traffic Prioritization

The Cisco SG 100D-08 delivers Quality of Service (QoS); all received

packets are examined for QoS priority encoding. The switch reads the

priority level and forwards the packet based on that priority level. For

example, during heavy loads voice and video traffic are given priority over

data traffic. (The switch is configured to comply with 802. 1 p, VLAN tagged

frames.) This ensures that time-sensitive traffic gets the highest level of

service.
