Description of Hardware
– 25 –
auto-negotiation of flow control, so the switch can automatically prevent port
buffers from becoming saturated.
RJ-45 P
ORTS
The switch contains four combination RJ-45 ports that operate at 10 Mbps or
100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. They are shared with
SFP ports 25~28. 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.
Because the RJ-45 ports support automatic MDI/MDI-X operation, you can use
straight-through cables for all network connections to PCs or servers, or to other
switches or hubs. (
See “Twisted-Pair Cable and Pin Assignments” on page 53 )
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.
