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.
• Compliant with IEEE 802.3, 802.3u, and 802.

REAR PANEL Figure 3 illustrates the rear panel of the SX8205R module. Figure 3.
Installation PACKAGE CONTENTS The following items are supplied: 1 SX8205R module 1 Regulated switching power supply with four plug adapters (North American, Australian, U.K., and European configurations); 100-240 VAC, 50-60 Hz input, 12 VDC output 1 Wall clip with two 4-40 x 0.
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.
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 standalone module, the unit can be placed on a desktop or can be mounted to a wall.
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.

Troubleshooting LED indicators on the front and rear panels of the SX8205R module allow you to monitor operational status: • The Power LED (Pelco badge) on the front panel (refer to Figure 2) allows you to monitor operating power. Refer to Table B for information about the Power LED and associated troubleshooting guidelines. • LED indicators on the rear panel (refer to Figure 3) allow you to monitor RJ-45 10BASE-T/ 100BASE-TX port status.
