Model Descriptions
SGPAT1013-105
: Once both the RJ-45 and the Fiber 1000Base-SX MM SC have established link, the ALPT function
is engaged. Then if either link goes down, the link status will propagate to the other port.
SGPAT1039-105
: Once both the RJ-45 and the Fiber 1000Base-SX MM LC have established link, then ALPT
function is engaged. If either link goes down, the link status will propagate to the other port.
SGPAT1040-105
: Once both the RJ-45 and the Fiber Dual Speed SFP port have established link. Then ALPT
function is engaged. If either link goes down, the link status will propagate to the other port.
SGPAT1040-205
: Only when the converter is in Redundancy Mode. Once link is established on the RJ-45 and one
of the Open Dual Speed SFP ports, then the ALPT function is engaged. If the RJ45 or both the SFP ports goes
down the link status will be propagated.
SGPAT1040-305
: Only when the converter is in Dual Converter mode. ALPT will work independently for each
virtual converter. Virtual converter 1 will use Ports 1 and 3, while Virtual converter 2 will use Ports 2 and 4. So for
Virtual converter 1 ALP will not be engaged until a valid link up condition is detected for RJ-45 Port 1 and SFP
Port 3. If either Port 1 or Port 3 goes down the link status will be propagated to the other port.
Virtual converter 2 ALP will not be engaged until a valid link up condition is detected for RJ-45 Port 2 and SFP
Port 4. If either Port 2 or Port 4 goes down the link status will be propagated to the other port.
