GE Multilin C30 Controller System 3-433 HARDWARE 3.4 MANAGED ETHERNET SWITCH MODULES33.4MANAGED ETHERNET SWITCH MODULES 3.4.1 OVERVIEWThe type 2S and 2T embedded managed switch modules are supported by UR-series relays containing type 9S CPU mod-ules with revisions 5.5x and higher. The modules communicate to the C30 through an internal Ethernet port (referred to asthe UR port or port 7) and provide an additional six external Ethernet ports: two 10/100Base-T ports and four multimode ST100Base-FX ports.The Ethernet switch module should be powered up before or at the same time as the C30. Otherwise, the switchmodule will not be detected on power up and the EQUIPMENT MISMATCH: ORDER CODE 500 self-test warning will beissued.3.4.2 MANAGED ETHERNET SWITCH MODULE HARDWAREThe type 2S and 2T managed Ethernet switch modules provide two 10/100Base-T and four multimode ST 100Base-FXexternal Ethernet ports accessible through the rear of the module. In addition, a serial console port is accessible from thefront of the module (requires the front panel faceplate to be open).The pin assignment for the console port signals is shown in the following table.Figure 3–45: MANAGED ETHERNET SWITCHES HARDWARETable 3–6: CONSOLE PORT PIN ASSIGNMENTPIN SIGNAL DESCRIPTION1 CD Carrier detect (not used)2 RXD Receive data (input)3 TXD Transmit data (output)4 N/A Not used5 GND Signal ground6 to 9 N/A Not usedNOTE842867A2.CDRTwo 10/100Base-TportsFour 100Base-FXmultimode portswith ST connectorsIndependent powersupply.
