NETWORK MANAGEMENT OPTIONS
With a comprehensive array of LEDs, the switch provides “at a glance”
monitoring of network and port status. The switch can be managed over the
network with a web browser or Telnet application, or via a direct connection to
the console port. The switch includes a built-in network management agent that
allows it to be managed in-band using SNMP or RMON (Groups 1, 2, 3, 9)
protocols. It also has an RJ-45 serial port on the front panel for out-of-band
management. A PC may be connected to this port for configuration and
monitoring out-of-band through a straight-through UTP or STP Ethernet cable
and the included RJ-45-to-DB-9 converter.
For a detailed description of the management features, refer to the Management
Guide.

RJ-45 PORTS
The switch contains two 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 1~2. 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 59)
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.
