3.2 10/100BASE-TX Fast Ethernet Ports
The switch can support connections to the following devices:
• 10BASE-T or 10/100BASE-TX network cards
• 10BASE-T hub ports
• 100BASE-TX hub ports
• 10/100BASE-TX dual speed hub ports
• 10/100BASE-TX switch ports
Auto-negotiation Capable
The ports support auto-negotiation function when establishing a link connection with any
auto-negotiation capable device. The connection speed and duplex mode are determined through
the negotiation process with the connected device.
Auto-speed-sensing
When connecting to a non-auto-negotiation device, half duplex mode is used. However, the ports can
auto-detect the connection speed.
Manual Configuration
The ports are configured to be enabled for auto-negotiation as factory default. However, it also
can be changed to one of the following fixed configurations through network
management operation:
• 10M Half-duplex
• 10M Full-duplex
• 100M Half-duplex
• 100M Full-duplex
Trunking Function
The ports are configured as normal data ports instead of trunking ports as factory default. In order to
support trunking function, any port can be configured as a trunking port manually through network
management operation. As configured, it is no longer a data port. For more details about trunking, refer to
section 3.4.
Flow Control
Half-duplex mode uses back pressure flow control to prevent the receiving buffer from being overrun by
data from a source node. Full-duplex mode uses the 802.3X flow control standard to prevent fast Physical
Ports data traffic from overrunning slow data traffic.
