Non-proprietary Connector Pinouts

This section contains pinout information for the non-proprietary connectors of your server, as follows:

L1 Port

The Cx-brick and R-brick have one L1 port that connects the brick's L1 controller to the L2 controller. This port uses a USB type B connector (see Figure A-1). Table A-5 lists the pin assignments for the USB type B connector.

External SCSI Port

The external SCSI port uses a SCSI 68-pin VHDCI connector (see Figure A-2). This connector is located on the IO9 PCI card in the IX-brick and on the TP900 storage module. Table A-6 shows the SCSI VHDCI pin assignments.

Serial and Console Ports

The IX-brick has two standard serial ports. As an option, two additional serial ports can be added to the IX-brick. These ports are capable of transferring data at rates as high as 230 kbps. Other features of the ports include the following:

  • Programmable data, parity, and stop bits

  • Programmable baud rate and modem control

The Cx-brick has one console port that connects the Cx-brick L1 controller to a system console.

Both the serial and console ports use a DB9 connector (see Figure A-3).

Ethernet Port

The Ethernet port, which is located on the L2 controller, uses an RJ-45 connector (see Figure A-4).

Table A-8 shows the cable pinout assignments for the Ethernet port operating in 10/100-Base-T mode and also operating in 1000Base-T mode.

Note: The system auto-selects the Ethernet port speed and type (duplex vs. half-duplex) when the server is booted, based on what it is connected to.
