3.16.4 XBRD-9060 I/O Expander Module
The optional XBRD-9060 module may be installed in the Upper Site of an air-
cooled XVME-6500 to bring more I/O to the front panel, as well as allow
mSATA SSD modules to be added for storage.
The following I/O is available on the front panel of the XBRD-9060:
•
One Gigabit Ethernet port via a standard RJ-45 connector. When this
port is enabled on the XBRD-9060 module, one of the Ethernet ports
on the P0 connector is disabled.
•
One RS-232 serial port. This port only contains TX/RX signals. It is
brought out on a mini USB-B connector, but an adapter cable is
included with the module for connection using a standard DB-9
connector.
•
Two USB 2.0 ports. These ports use standard USB-A connectors and
can operate as either USB 2.0 or USB 1.1 connections.
The XBRD-9060 contains 2 mSATA sockets that allow 2 SSD drives to be added
to the XVME-6500 while still remaining within a single VME slot. Using the
software RAID functionality of the QM87 PCH, these drives can even be setup
as a RAID0/1 array if redundancy or extra speed is desired.
3.16.5 Power Available to Expansion Modules
The power requirements given in Section
expansion modules. The amount of power available to the expansion sites
depends on which CPU is used on the XVME-6500, the programmable PL1
power limit used for that CPU, and what type of backplane/power supply
combination is powering it. In order to maintain the stability and long life of
the XVME-6500, the programmed CPU PL1 power limit should be set
according to the following equation:
PL1 = Total Available 5V Power - Expected Combined Expansion Card 5V Power - Rest of Board 5V Power.
The Total Available 5V Power is determined by the backplane type:
Backplane Type
Total Available 5V Power
5-row with 5V & 3.3V supplied
90W
5-row with 5V only supplied
87.5W (2.5W of 3.3V made from 5V)
3-row with 5V only supplied
57.5W (2.5W of 3.3V made from 5V)
Expected Combined Expansion Card 5V Power is the amount of 5V power the
installed PMC/XMC expansion modules are expected to consume.
The Rest of Board 5V Power is ~23.5W (typical).
Example 1:
An XVME-6500 is used in a 5-row backplane with 5V only power. The expected
expansion card power is 40W. To determine the value to use for PL1:
PL1= 90W - 40W
–
23.5W = 26.5W.
A value no larger than 26.5 should be
programmed into the BIOS setup utility for PL1 in this situation.
