The Ethernet (RJ-45) connector has one LED that indicates Ethernet-link status.
When this green LED is on, there is an active connection on the Ethernet port.
Activity between the server and the network is indicated by the Ethernet
transmit/receive activity LED on the front of the server (see the
User’s Guide on the
IBM xSeries Documentation CD).
Ethernet connector
There is an RJ-45 Ethernet connector on the back of the server. See “System-board
external port connectors” on page 5 for the location of this connector. The following
illustration shows the pin-number assignments for the RJ-45 connector. These
assignments apply to both 10BASE-T and 100/1000BASE-TX devices.

RS-485 (ASM interconnect) ports
The RS-485 connectors are used for the ISMP interconnect function. The ISMP
interconnect function uses these connectors to daisy-chain several system service
processors together. This function enables the service processors to communicate
with each other in half-duplex mode.
