• One front panel slide-in module interface for a 2-port
1000BASE-SX, , 1000BASE-T, or GBIC Gigabit Ethernet
module.
• RS-232 DCE Diagnostic port (console port) for setting up
and managing the Switch via a connection to a console
terminal or PC using a terminal emulation program.
Performance Features
Layer 2 Features
• 8.8 Gbps switching fabric capacity
• Store and forward switching scheme.
• Full and half-duplex for both 10Mbps and 100Mbps
connections. The front-port Gigabit Ethernet module
operates at full-duplex only. Full-duplex allows the switch
port to simultaneously transmit and receive data, and
only works with connections to full-duplex capable end
stations and switches. Connections to hubs must take
place at half-duplex.
• Supports IEEE 802.3x flow control for full-duplex mode
ports.
• Supports Back-pressure flow control for half-duplex
mode ports.
• Auto-polarity detection and correction of incorrect
polarity on the transmit and receive twisted-pair at each
port.
• IEEE 802.3z compliant for all Gigabit ports (optional
module).
• IEEE 802.3x compliant Flow Control support for all
Gigabit ports (optional module).
• IEEE 802.3u compliant for 1000BASE-T (Copper)
Gigabit ports (optional module).
