Headers and TestPoints

and

J11

are used to select the VPWR source for position 0 and 1 respectively.

When the Shunt closes 1-2 – 12V is selected. With 2-3 closed 5V is selected. FET's

are used to provide a low impedance path from the power supplies to VPWR for each

position. Options are in place on the PCB to allow hardwired selections for clients who

prefer a fixed voltage. The headers are not installed when the fixed voltage option is in

place. With pin 2 open VPWR will be open.

J12, 13, and

are used to select the bezel grounding option. 1-2 selects AC coupled,

2-3 selects DC coupled and open is open. J12 = PCIe Bezel. J13 = Slot 0. J23 = Slot

is an optional header for SMB connection. Pin 1 is data and pin 2 is clock. Both are

pulled up. 3

party tools can be used to see the "innards" of the switch. Usually not

needed but handy if you are doing development or want to talk through the switch to the

XMC positions.

TP1

is an optional JTAG header used to connect to XMC 0. The pin definitions are in

the silk. 1: 3.3V, 2: GND, 3: TMS, 4: TDO, 5: TDI, 6: TCK, 7: TRST

J19

control the voltage on 33,67 of P2 and P7 respectively when the SCSI

connector options are selected. 1-2 selects 3.3V and 2-3 selects ground on those pins.

The shunt and traces are rated for 1A. Not fuse protected.

J20

control the voltage on 34,68 of P2 and P7 respectively when the SCSI

connector options are selected. 1-2 selects 3.3V and 2-3 selects ground on those pins.

The shunt and traces are rated for 1A. Not fuse protected.

J16

J17

provide the serial port connections when installed. J16 is for Serial Port 0

and J17 is for serial port 1 on XMC0. Pin 1 is TX and pin 2 is Rx. Pin 3 is a ground

reference. Standard serial connections IAW 2.15 from Pn4 when this option is installed

J10

J18

provide the ethernet port connections when installed. J10 is for ethernet Port

0 and J18 is for ethernet port 1 on XMC0. Standard Ethernet connections IAW 2.15

from Pn4 when this option is installed

P3, 4, 6

are optional power connectors to allow for added 12V power to be used by the

PCIe8LXMCX2. The PCIe gold fingers allow for about 60W of power to be consumed

by the board across all XMC voltages including power supply losses. In many cases
