Description of Hardware
10/100/1000BASE-T Ports
These ports are RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or
full duplex, or at 1000 Mbps, full duplex. Because all ports on this switch
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 “1000BASE-T Pin Assignments” on page B-4.)
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.
SFP Slots
The Small Form Factor Pluggable (SFP) transceiver slots are shared with
four of the RJ-45 ports (ports 21~24 for the SMC8624T and ports 45~48
for the SMC8648T). 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.
