Chapter 3: Interface and Cabling Information

The Ethernet Interface Connection

The system comes with a single 100 Base-T 8-pin Ethernet connector. Optional boards

supporting additional Ethernet connectors are available.

Table 3-1 shows the cable pinout assignments for the Ethernet 100-BASE T Ethernet port.

Figure 3-1 shows the location of the standard Ethernet connector on the rackmount

system.

There are two LEDs on the RJ-45 Ethernet. The top (green) LED lights only when the

system is transmitting. The bottom (yellow) LED lights whenever it sees any packet on

the wire, including packets not destined for your system.

The four LEDS above the RJ-45 Ethernet connector have the following functions:

• The yellow LED on the far left (LED 1) lights to indicate SCSI activity on the BaseIO

single-ended SCSCI connector.

• The green LED (LED 2) lights to indicate 100 MB-per-second packet activity.

• The yellow LED on the right (LED 3) indicates when the Ethernet is operating at full

duplex rates of transfer or receive.

• The green LED on the far right (LED 4) shows the Ethernet link test. It lights when

link state is valid.
