SFPTotal Mini HW revision 1.3

SFPTotal Mini programming board allows to reprogram SFP, SFP+ and SFP28 transceivers, and is designed to address the main problems that arise in practice of Internet service providers, network equipment vendors and system integrators in the process of working with optical transceivers and switching equipment, and require reprogramming of transceivers.

Device is a fully compatible according SFF-8074

The SFPTotal Mini connects to PC via USB interface through which performed control and power supply of device.

To connect a high-power transceivers can be used by external power supply adapter 5V DC.


Application

Programmers SFPTotal are used to solve next tasks:

  • Programming SFP/SFP+ optical transceivers and twinaxial cables
  • Providing of compatibility between network equipment of different manufacturers
  • Reflashing memory of write-protected transceivers
  • Changing settings of PHY controllers
  • Branding for OEM transceivers
  • Diagnosis transceiver by reading the DDM
  • Accounting for optical transceivers

Quick start

  1. Connect SFPTotal Mini board to your PC using micro USB Type B cable
  2. Install drivers for SFPTotal Mini
  3. Download application SFPTotal Wizard
  4. Start SFPTotal Wizard
  5. Insert transceiver to the programmer port
  6. Reading transceiver's memory

Control elements

LED indications

  • POWER lights up when device is connected to PC.
  • STATUS flashes when the power is on and device waiting for connection transceiver to the SFP port. When transceiver is connected, STATUS led is constantly light up.
  • ERROR constantly lights up when device works with error or freezes.
  • TX_ENA lights up when the transmitter contacts connected to power supply.
  • RX_ENA lights up when the receiver contacts connected to power supply.

Jumpers

  • TX turns transmitter power
  • RX turns receiver power
  • Сontact closure LPMODE disables low-power mode (transmitter disabled).
  • Сontact closure RS0 and RS1 pull up appropriate contacts of transceiver to the ground.

Software

To operate the device, use the software SFPTotal Wizard version 1.0.2.3 or above.

Command line interface

The device provides access to the command line interface by connecting through a virtual serial port. You can use the programming board without SFPTotal Wizard software to get more features or to realize the opportunities that are not available in the standard software.

Use this document to get information about commands which supported by SFPTotal Mini.

Commands

CLI

The command switches the echo output of command line. Default, CLI=0.

CLI
CLI=0


STATUS

Returns current state GPIO of SFP transceiver.

STATUS
MOD_ABS=0; TX_FAULT=1; RX_LOS=0; TX_DIS=0


TX_DIS

Command allows to disable power supply of transmitter for switching to low power mode (LPMODE). To activate the LPMODE, it is necessary to transfer command TX_DIS setting the flag value of 1.

To disable the mode, you must set the flag equal to 0. The current state can be requested with STATUS command.

TX_DIS=1

STATUS
MOD_ABS=0; TX_FAULT=1; RX_LOS=0; TX_DIS=1

TX_DIS=0
STATUS
MOD_ABS=0; TX_FAULT=1; RX_LOS=0; TX_DIS=0

Low power mode is activated for default. On the PCB of SFPTotal Mini board are placed contacts LP_MODE, which allows to switch low power mode in manual mode.


VERSION

Command returns information about device: hardware revision, software version and unique serial number of the device.

wXYYAABBCC (WXYYAABBCC)

Command for writing to the memory of transceiver.

w — (1 byte) — Write command. Symbol register is responsible for the subsequent read after write. If you use uppercase (W) after the recording is complete programmer will make reading the memory area which has been overwritten. To write without return a write result of lower case (w) must be used.

X — (1 byte) — Transceiver type (1 - SFP, 2 - SFP+).

YY — (2 bytes) — The device address on the I2C bus.

AA — (2 bytes) — Address of additional table.

BB — (2 bytes) — Address table. Value in HEX. For example: A0 or A2.

СС — (2 bytes) — Write byte count. Hexadecimal value reduced by one. For example, for writing 128 bytes you should set this parameter in 7F (0x7F in HEX, 127 in decimal).

{DATA} — Write data in HEX, 2 characters for each byte of the parcel.


Examples

Write code 128 bytes in Table A0 Upper address 00 for SFP transceiver:

W1A000007F

Note: Write command should type without newline characters and spaces. Shifts are given for the convenience display of the material in the examples.


I2CRATE

Note: Supported only on the SW versions 1.1.0 or above

This command sets the speed of I2C data bus.

I2CRATE=12 # Set up speed rate 100 kHz
I2CRATE=40 # Set up speed 30 kHz
I2CRATE=C6 # Set up speed 10 kHz

To request a current speed use command: ? I2CRATE

? I2CRATE
I2CRATE=C6


AUTO_WR_ADDTBL

Note: Supported only on the SW versions 1.1.0 or above

If the flag is set, the programmer will automatically change the address of the additional tables before performing reading and writing operations.

AUTO_WR_ADDTBL=1
 
AUTO_WR_ADDTBL=0

To request a current value use command: ? AUTO_WR_ADDTBL

? AUTO_WR_ADDTBL
AUTO_WR_ADDTBL=0
