Rear view

The following illustration shows the connectors and LEDs on the rear of the server.
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 pointing device in a C2T chain. If the server is not part of a C2T
chain, this LED remains lit. A select LED is also on the front of the server.
Tx/Rx LEDs: These LEDs are on the dual Ethernet connector. When the up-arrow
or down-arrow LED is lit, it indicates that there is activity between the server and
the network attached through the upper or lower connector.
Ethernet connectors: Use these connectors to connect the server to a network.
USB connector: Connect a USB device to this connector.
ISM connector: Use this connector to connect the server 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
C2T Out connector: Connect a breakout cable to this connector, or use this
connector to connect the server to the C2T In connector of another server in a C2T
chain.
Serial connector: Connect a 9-pin serial device to this connector.
C2T In connector: Use this connector to connect the server to the C2T Out
connector of another server in a C2T chain.
