About the Switch
1-2
Management Options
This switch contains a comprehensive array of LEDs for “at-a-glance” monitoring of
network and port status. It also includes a management agent that allows you to
configure or monitor the switch using its embedded management software, or via
SNMP applications. To manage the switch, you can make a direct connection to the
RS-232 console port (out-of-band), or you can manage the switch through a network
connection (in-band) using Telnet, the on-board Web agent, or Windows-based
network management software.
The management agent provides a wide range of advanced performance-enhancing
features. Port-based VLANs provide traffic security and efficient use of network
bandwidth. QoS priority queueing ensures the minimum delay for
moving real-time
multimedia data through the switch. Flow control
eliminates the loss of packets due to
bottlenecks caused by port saturation. Port security is provided to filter unwanted
traffic from the switch.
For a detailed description of the switch’s advanced features, refer to the
Management Guide.
Description of Hardware
RJ-45 Ports
The switch base unit contains 24 10BASE-T/100BASE-TX RJ-45 ports. All of these
ports support automatic MDI/MDI-X operation, so you can use straight-through
cables for all network connections to PCs or servers, or to other switches or hubs.
(See “10BASE-T/100BASE-TX Pin Assignments” on page B-2.)
Each of these ports support auto-negotiation, so the optimum transmission mode
(half or full duplex), and data rate (10 or 100 Mbps) can be selected automatically, if
this feature is also supported by the attached device. If a device connected to one of
these ports does not support auto-negotiation, the correct speed will be sensed by
the port, but the transmission mode will default to half duplex.
Each port also supports auto-negotiation of flow control, so the switch can
automatically prevent port buffers from becoming saturated.
