30 AT-9900 Series Switch
C613-03084-00 REV A
SFP port and RJ-45 port operation
On AT-9924T/4SP and AT-9924T switches, 24 ports are operational at one time
out of a total of four SFP ports and 24 RJ-45 ports.
The RJ-45 ports 1 to 4 use the same physical interface as the SFP ports 1 to 4.
When a SFP is inserted, the corresponding RJ-45 port is disabled. For example,
if a SFP is inserted in SFP port 1 then RJ-45 port 1 is disabled. All other RJ-45
ports function as normal and when the SFP is removed from port 1 the RJ-45
port 1 is operational.
