ESD Warning
Electronic components and circuits are sensitive to
ElectroStatic Discharge (ESD). When handling any circuit
board assemblies including Connect Tech COM Express
carrier assemblies, it is recommended that ESD safety
precautions be observed. ESD safe best practices include,
but are not limited to:
Leaving circuit boards in their antistatic packaging
until they are ready to be installed.
Using a grounded wrist strap when handling circuit
boards, at a minimum you should touch a grounded
metal object to dissipate any static charge that may be
present on you.
Only handling circuit boards in ESD safe areas, which
may include ESD floor and table mats, wrist strap
stations and ESD safe lab coats.
Avoiding handling circuit boards in carpeted areas.
Try to handle the board by the edges, avoiding contact
with components.

CLI Management Interface
CLI Access via the RS232 Serial Port
To use the CLI management on the VPG you must connect to the RS-232 external management serial port (P3)
or through the backplane serial port connection. Only TX, RX and GND connections are needed for operation.
You then must open the serial port in a terminal program such as: RealTerm, Putty, HyperTerminal, minicom,
etc. The COM port must be set up to run with a baud rate of 115200, 8 data bits, 1 stop bit and no parity.
Note: the VPG external serial port is compatible with RS-232 Input/Output Levels (NOT TTL or CMOS).

CLI Basics
Once opening the COM port attached to the management port, after boot up your terminal output should look
like the output below. The default login is admin and password is blank(“”). So after typing admin hit
<ENTER> then hit <ENTER> again to login and “?” will display a list of the available commands.
Below is a list of common quick CLI commands. For a complete CLI reference please see the documents
described below.

Web Management Interface
The GraphiteVPX/GbE 16+4 - Port - Managed Carrier Ethernet Switch allows users to configure and monitor
the device from any web enabled device. Below describes how to access this management interface as well as
provides on overview on the web GUI itself.
Accessing the Web Management Interface
There are two ways to access the web interface for first time use.
Method #1 - Using the default shipping IP
This method DOES NOT require having access to the CLI interface. By default the GraphiteVPX/GbE will
have an IP address of 192.168.42.1, if you would like to connect to this address follow the steps below:
oDirectly connect any port of GraphiteVPX/GbE to your host PC using a standard Cat5e ethernet
cable
oSetup your host PC’s IP address to be on the same subnet as GraphiteVPX/GbE (192.168.42.X)
oOpen a web browser and go to the 192.168.42.1 address.
oNow you should see the login screen and from here you can setup the GraphiteVPX/GbE to an IP
address on your network.
Method #2 –Changing the GraphiteVPX/GbE IP to one on your network via the CLI
This method requires having access to the CLI interface through means of the external management serial port
or the PCIe/104 bus
oLogin to the CLI interface
oType in the following commands
oconfigure terminal
ointerface vlan 1
oip address xxx.xxx.xxx.xxx 255.255.255.0
oend
oNow connect GraphiteVPX/GbE to any place on your network.
oOnce the system is up simply go to your specified address of xxx.xxx.xxx.xxx in a web browser of
your choice and you will see the login screen for the web interface
Login Screen of Web Management Interface
To login into the web management interface, the default login is admin and the password is blank.

Port LED Details
The VPG uses a serialized LED stream to output the LED status for each port. This serial signal is intended to
be run through shift registers as shown below to de-serialize the stream. To accommodate the 16 ports
(VPG202 –Backplane only) requires the use of four 8-bit shift registers (or eqivilant) setup in the
configuration shown below.
An example circuit is shown below, or an example schematic can be downloaded here.

System Management Interface
The GraphiteVPX/GbE supports a slave I2C slave interface on the SM0 (SCL) and SM1 (SDA) signals
connected to the VPX backplane. The I2C address of this interface is determined by the Geographic Address
lines GA0#, GA1#, and GA2#. This interface operates at 100 KHz.
There are 10K OHM pull-ups to the +3.3V_AUX supply on the I2C slave interface on SM0 and SM1.
The I2C interface contains an I2C mux device (PCA9544) to allow the user access 5 temperature sensors that
monitor board edges and internal temperatures of the Ethernet Switch and Ethernet PHY.
Addressing the I2C Slave Interface (I2C Mux)
As stated above, the I2C slave interface uses GA0#, GA1#, and GA2# to determine its final I2C address. See
more details below. Refer to your backplane GA (Geographical Address) lines for the complete configuration
address.
The I2C address will be as such:
Bit7
BIT6
BIT5
BIT4
BIT3
BIT2
BIT1

Writing to the I2C Slave Interface
Refer to the NXP PCA9544 datasheet for access details.
The I2C multiplexor is like a ‘gate’ to open an on board I2C bus to access one of three card side busses:
1) Bus 0 –is a link to one TMP422 (sensor #5) remote temperature sensor (local temp and remote
temperatures of VSC7429 and VSC8512).
2) Bus 1 –is a direct link with XMC sites I2C system interface
3) Bus 2 –is a link to 2 TMP101 temperature sensors on the top edge (Sensor 1 and 2)
4) Bus 3 –is a link to 2 TMP101 temperature sensors on the bottom edge (Sensor 3 and 4)
*Refer to the TI TMP101 datasheet for access and setup of ALERT pin interrupt to the PCA9544. A Thermal
Alert LED is accessible on the solder side of the card if a visual indicator is required.
Reading from the I2C devices
When reading from the I2C slave interface, the last value stored in the command register by a write operation
is used to determine which command to respond to. To change the command for a read operation, a new
command must be written to the command register. This is accomplished by issuing an I2C slave address byte
with the R/W# bit LOW, followed by the command byte. The master can then generate a START condition
and send the I2C slave address byte with the R/W# bit HIGH to initiate a read command. If repeated reads
from the same register are required it is not necessary to continually send the command byte. The slave I2C
interface will remember the original command value until it is changed by the next write operation.
Example XML code to open the I2C mux and access the temperature sensors using the Totalphase Aardvark™
USB to I2C controller can be provided by request.
