use straight-through cables for all network connections to PCs or servers, or to other 
switches or hubs. (See “1000BASE-T Pin Assignments” on page C-16)

Each of these ports support auto-negotiation, so the optimum transmission mode 
(half or full duplex), and data rate (10, 100, or 1000 Mbps) can be selected 
automatically. If a device connected to one of these ports does not support 
auto-negotiation, the communication mode of that port can be configured manually.

Each port also supports auto-negotiation of flow control, so the switch can 
automatically prevent port buffers from becoming saturated.

On the OS-LS-6224U, there are two RJ-45 ports, which are shared with two of the 
SFP transceiver slots.

On all devices except OS_LS_6224U 100Base-FX ports, the Small Form Factor 
Pluggable (SFP) transceiver slots are shared with two of the RJ-45 ports (Ports 
25~26/49~50). In its default configuration, if an SFP transceiver (purchased 
separately) is installed in a slot and has a valid link on its port, the associated RJ-45 
port is disabled and cannot be used. The switch can also be configured to force the 
use of an RJ-45 port or SFP slot, as required.
