Management Options
This switch contains a comprehensive array of LEDs for
“at-a-glance” monitoring of network and port status. It also
includes a Network Management Module that allows the switch to
be managed in-band via SNMP or RMON (Groups 1, 2, 3 and 9)
protocols, with a Web browser, or remotely via Telnet. The switch
also provides a serial port on the rear panel for out-of-band
management.
There is also support for a Redundant Power Unit to ensure
continuous operation in the event of a power failure.
Description of Hardware
10BASE-T/100BASE-TX Ports (SMC6948L2)
These ports are dual-speed RJ-45 ports with built-in wiring
crossovers (MDI-X). Workstations and servers can be connected to
these ports with straight-through cable. When connecting to
another switch or a hub, you can use straight-through cable to
connect to a port on the attached device that does not have
built-in wiring crossovers (MDI), or use crossover cabling. (See
Appendix B for a pinout description of crossover cable.)
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 a device
connected to one of these ports does not sup port auto-negotiation,
the communication mode of that port can be configured manually.
Each port also supports IEEE 802.3x auto-negotiation of
full-duplex flow control, so the switch can automatically prevent
port buffers from becoming saturated.
