connection (in-band) using Telnet, the on-board web agent, or
SNMP-based network management software.
The management port (RJ-45) provides a dedicated management channel
that operates outside of the data transport network. This makes it possible
to re-configure or troubleshoot the switch over either a local or remote
connection to the management port when acces s via the data channel is
not possible or deemed insecure.
For a detailed description of the switch’s advanced features, refer to the
SMC7824M/ESW Management Guide.
Description of Hardware

100BASE-TX and 1000BASE-T Ports

The switch contains 24 100BASE-TX RJ-45 ports that operate at
10/100 Mbps, half or full duplex, and two 1000BASE-T RJ-45 ports that
operate at 10 Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full
duplex. Because all of 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 “1000BASE-T Pin
Assignments” on page B-5.)
Each of these ports support auto-negotia tion, 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-n egotiation, 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.

100BASE-TX Management Port

The 10/100BASE-TX port labeled “Mgmt” provides a dedicated
management interface which is segregated from the data traffic crossing
the other ports.
