Rear view The following illustration shows the connectors and LEDs on the rear of the server. Power-cord connector System-error LED Link LEDs Select LED Ethernet 2 connector C2T IN connector IN Serial connector C2T OUT connector OUT Power LED USB 3 connector Ethernet 1 connector ISM connector Power-cord connector: Connect the power cord to this connector. System-error LED: When this LED is lit, it indicates that a system error has occurred. An LED on the Light Path Diagnostics panel on the system board is also lit to help isolate the error. A System-error LED is also on the front of the server. Select LED: When this LED is lit, it indicates that this server is using the monitor, keyboard, and mouse that are connected to the C2T chain. If no other servers are chained to this server, this LED remains lit. A select LED is also on the front of the server. Link LEDs: These LEDs are on the dual Ethernet connector. When either the upor down-arrow LED is lit, it indicates an active link between the server and the network device attached through the upper or lower connector. Ethernet 2 connector: Use this connector to connect the server to a network. USB 3 connector: Connect a USB device to this connector. Ethernet 1 connector: Use this connector to connect the server to a network. ISM connector: Use this connector to connect to an optional Remote Supervisor Adapter. Power LED: When this LED is lit, it indicates that ac and dc power are present in the server. When this LED is flashing, it indicates that the server is in Standby mode. When this LED is off, ac power is not present, or the power supply or the LED itself has failed. A power LED is also on the front of the server. Note: If this LED is off, it does not mean that there is no electrical power in the server. The LED might be burned out. To remove all electrical power from the server, you must disconnect the power cord from the electrical outlet. C2T OUT connector: Use this connector to connect to a breakout cable or to the C2T IN connector of another xSeries 335 or xSeries 330 server. Serial connector: Connect a 9-pin serial device to this connector. 28 IBM xSeries 335 Type 8676: Installation Guide

System-error LED:
When this LED is lit, it indicates that a system error has
occurred. An LED on the Light Path Diagnostics panel on the system board is also
lit to help isolate the error. A System-error LED is also on the front of the server.
Select LED:
When this LED is lit, it indicates that this server is using the monitor,
keyboard, and mouse that are connected to the C2T chain. If no other servers are
chained to this server, this LED remains lit. A select LED is also on the front of the
server.
Link LEDs:
These LEDs are on the dual Ethernet connector. When either the up-
or down-arrow LED is lit, it indicates an active link between the server and the
network device attached through the upper or lower connector.
Ethernet 2 connector:
Use this connector to connect the server to a network.
USB 3 connector:
