Feature Description
Power Efficiency
Energy Detect Automatically turns off power on Gigabit Ethernet RJ-45 port when the switch detects a link down
Active mode is resumed without loss of any packets when the switch detects the link is back up
Cable length detection Adjusts the signal strength based on the cable length. Reduces the power consumption for cables shorter than 10 m.
General
Jumbo frames Frame sizes up to 10 KB supported on 10/100 and Gigabit interfaces
(9K for SG200-08 and SG200-08P)
MAC table Up to 8000 MAC addresses
Discovery
Link Layer Discovery Protocol
(LLDP) (802.1ab) with LLDP-
MED extensions
LLDP allows the switch to advertise its identification, configuration, and capabilities to neighboring devices, which
store the data in an MIB. LLDP-MED is an enhancement to LLDP that adds the extensions needed for IP phones.
Cisco Discovery Protocol The switch advertises itself using the Cisco Discovery Protocol (available April 2011)
Power over Ethernet (PoE)
Maximum power of 15.4W to any 10/100 or Gigabit Ethernet base port. The total power available for PoE per switch is
as follows:
Model Power Dedicated to PoE Number of Ports That Support PoE
SF200-24P 100W 12
SF200-48P 180W 24
SG200-08P 32W 4
SG200-26P 100W 12
