Product Overview  
DESCRIPTION  
The SX8205R unmanaged Ethernet switch provides five 10BASE-T/100BASE-TX ports for the transport of  
bidirectional Ethernet data. Operating as a single switch in a network, the SX8205R module connects to up  
to five 10BASE-T/100BASE-TX Ethernet devices. If a larger switched network is needed, multiple SX8205R  
switches can be connected by allowing a port on each switch to be used as an uplink port. Refer to Figure 1  
for illustrations of single-switch and multiple-switch applications.

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).

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.

NOTE: TX Mode configuration must be set when the module is powered off. If you wish to change  
a TX Mode switch setting after the module has been powered on, power off the module, change the  
TX Mode switch setting, and then power on the module again.  
MOUNTING  
The SX8205R module can be mounted into a rack or can be used as a stand-alone module. As a stand-  
alone module, the unit can be placed on a desktop or can be mounted to a wall.  
NOTE: As a matter of convenience, it is recommended that you set the modes of operation for each  
10BASE-T/100-BASE-TX port—if required—before mounting the SX8205R module into a rack or onto  
a wall. For information about setting the port modes of operation, refer to Setting 10BASE-T/  
MOUNTING THE SX8205R MODULE INTO A RACK  
The SX8205R module can be installed into an RK5000 Series rack mount chassis, which can be  
mounted into an industry-standard 19-inch (48.26 cm) equipment rack. The RK5000 Series rack mount  
chassis includes the following models:  
RK5000PS-3U and RK5000-3U: Designed to accommodate fiber optic modules as follows:  
The RK5000PS-3U rack mount chassis provides 12 single-width module slots and a  
power supply.  
The RK5000-3U rack mount chassis provides 14 single-width module slots (a power  
supply is not included). Power to the modules can be supplied using the optional  
external power supply (EPS5000-120).  
For additional information, refer to the RK5000PS-3U/RK5000-3U Fiber Rack Mount Chassis  
Installation manual.  
RK5000PS-5U: Designed to accommodate Enduramodules but can also accommodate fiber  
optic modules and the SX8205R module with the use of the appropriate adapter kit. The  
RK5001-1UEXP adapter kit is required for installation of the SX8205R module into the  
RK5000PS-5U chassis.  
MOUNTING THE SX8205R MODULE TO A WALL  
The SX8205R module can be mounted to a wall in the following ways:  
Using the supplied wall clip for attachment of a single module to a wall. For installation  
Using the optional WM5001 wall mount kits, which are designed for mounting of single-width  
fiber optic modules. The WM5001-3U base kit allows mounting of a single module to a wall.  
The WM5001-3UEXP expansion kit allows mounting of an additional module. It is  
recommended that a maximum of three expansion kits be used with the base kit, allowing a  
maximum of four single-width modules to be mounted to a wall.  
NOTE: The WM5001 wall mount kits can be used with the WM5002 wall mount kits, which are  
designed for mounting of double-width fiber optic modules. If mounting a mix of single-width  
and double-width modules is desired, it is recommended that a maximum of two single-width  
modules and one double-width module be mounted in combination with one another.  
For mounting instructions using the wall mount kits, refer to the WM5000 Series Wall Mount  
Kit Installation manual.

Mounting the SX8205R Module Using the Wall Clip  
NOTE: Before mounting the SX8205R module to a wall, ensure that there is adequate space at both  
ends for viewing the front-panel Power LED and for making the various rear-panel cable connections.  
To attach the SX8205R module to a wall using the supplied wall clip, refer to Figure 5 and do the  
following:  
1. Using the two vertical or horizontal wall-mounting holes, attach the wall clip to a wall using  
two screws (not provided).  
2. Slide the module into the clip until the two holes on the bottom of the module align with the  
two holes on the lower flange of the clip.  
3. Attach the module to the clip using the two Phillips pan head screws provided for the clip.

NOTES:  
A 12 VDC or 24 VAC power supply can be used to power the module when used as a  
stand-alone unit. A 12 VDC power supply is provided. If a 24 VAC power supply is used,  
the power supply must be a Listed Direct Plug-In Power Unit marked as Class 2 and  
rated as 24 VAC, 0.50 A (minimum output).  
In extreme temperature conditions, it is recommended that an industrial-rated outdoor  
power supply such as the Pelco WCS1-4 power supply be used.  
10BASE-T/100BASE-TX connections  
NOTES:  
Use Cat5e or a higher category of cable to connect to a 10BASE-T/100BASE-TX port.  
Cable length must not exceed 328 feet (100 meters).  
The 10BASE-T/100BASE-TX ports are auto MDI/MDI-X ports; therefore, either a  
straight-through or crossover cable can be used. The ports automatically detect the  
cable type that is used. Refer to Appendix. RJ-45 Connector Pinouts on page 22 for  
pinout information.

page 10 for information.  
*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.
