SETTING 10BASE-T/100BASE-TX PORT MODES OF OPERATION

NOTE: As a matter of convenience, it is recommended that you verify the modes of operation for

each 10BASE-T/100-BASE-TX port and then change the mode settings—if necessary—before
mounting the SX8205R module into a rack or onto a wall.

The SX8205R module provides various configuration options that allow you to select the desired
modes of operation for each 10BASE-T/100BASE-TX port (ports 1-5). You can select the desired
modes of operation by means of a TX Mode switch that is provided on the bottom of the module for
each port (refer to Figure 4).

TX MODE SWITCHES - PORTS 1-5

TX Mode

Figure 4. TX Mode Switches for 10BASE-T/100BASE-TX Ports 1-5

10 C2626M (2/07)

Using the TX Mode switch for a particular port, you can do the following:

• Enable autonegotiation or select (force) a specific data rate and duplex mode:

– Enabling autonegotiation allows the SX8205R module to automatically negotiate with

the device to which the port is connected for data rate and duplex modes of operation:
10 Mbps or 100 Mbps data rate and half-duplex or full-duplex mode. The highest
common denominator of operational modes is automatically selected.

Autonegotiation is enabled by default.

– If autonegotiation is not desired, you can select a specific data rate and duplex mode:

• Data rate configuration allows you to select 10 Mbps or 100 Mbps.

• Duplex mode configuration allows you to select half-duplex mode or full-duplex

mode.

• Enable or disable flow control. Flow control controls data transmission at the sending device
to avoid overfilling buffers and losing data at the receiving device. When the buffers on the
receiving device are full, a message is sent to the sending device to suspend the transmission
until the data in the buffers has been processed.

NOTE: For time-sensitive data applications (for example, video and audio applications), it is
recommended that flow control be disabled.

Flow control is disabled by default.

With the SX8205R module powered off, set each TX Mode switch to the desired modes of operation.
Refer to Table A for TX Mode switch settings and corresponding 10BASE-T/100BASE-TX port modes
of operation. Note that each 10BASE-T/100BASE-TX port operates independently of one another;
therefore, each port can be set to different modes of operation as appropriate.

If a normal collision occurs, no
action is required.
If a problem with the network
exists due to excessive colli­sions, do any of the following
as appropriate:

• If half-duplex mode is not
required, set the TX Mode
switch to full-duplex mode
by means of autonegotia­tion or by forcing the mode
(refer to Setting 10BASE-T/

following as applicable:

– Replace network cable

if it is defective or if it is
not the proper cable
type. Use Cat5e or
higher cable.

– Ensure that cable is

proper length. Cable
length must not exceed
328 feet (100 meters).

– Replace the network

interface card (NIC) if it
is defective or if it is
incompatible.

– Segment the network.

*A collision is a normal event on a half-duplex Ethernet link. A collision occurs when two or more devices,

referred to as stations, attempt to transmit at the same time on a shared physical medium.

Ethernet uses the CSMA/CD (Carrier Sense Multiple Access/Collision Detect) media access method by
which two or more stations share a common transmission medium. Using CSMA/CD, a station monitors
the medium and transmits a message in bit-serial form when it senses that no other station is
transmitting. If, after initiating a transmission, the message collides with that of another station, each
transmitting station then intentionally transmits for an additional predefined period to ensure
propagation of the collision throughout the system. To avoid another collision, each station waits a
random amount of time (backoff) before attempting to transmit again.

Excessive collisions occur when retransmission of a frame fails after 16 consecutive times and the frame
is dropped. Excessive collisions may indicate that the network is becoming congested.
