Ethernet link status LEDs: When these LEDs are lit, they indicate that there is an active link connection on the 10BASE-T, 100BASE-TX, or 1000BASE-TX interface for the Ethernet port.

Ethernet activity LEDs: When these LEDs are lit, they indicate that the server is transmitting to or receiving signals from the Ethernet LAN that is connected to the Ethernet port.

PCI slots 1-4:When PCI adapters are installed in the server, the external adapter connectors are located in these four slots.

Power-cord connectors: Connect the power cords to these connectors.

AC power LED: On some server models, each hot-swap power supply has an ac power LED and a dc power LED. During typical operation, both the ac and dc power LEDs are lit. For any other combination of LEDs, see the Hardware Maintenance Manual and Troubleshooting Guide on the IBM xSeries Documentation CD.

DC power LED: On some server models, each hot-swap power supply has a dc power LED and an ac power LED. During typical operation, both the ac and dc power LEDs are lit. For any other combination of LEDs, see the Hardware Maintenance Manual and Troubleshooting Guide on the IBM xSeries Documentation CD.

SCSI connector: Connect a SCSI device to this connector.

ASM connectors: Use either of these connectors to connect the server to an Integrated xSeries Adapter (IXA) that is installed in the server.

System-locator LED: Use this LED to visually locate the server among other servers. You can use IBM Director to light this LED remotely.
