Programmer SFPTotal Plus

SFPTotal Plus - the new version of four-ports programming board, replacement for programmers PG series. Programmer SFPTotal Plus allows to reprogram the GBIC, SFP, SFP+, XFP and QSFP transceivers and direct attach cables (DAC).

The hardware platform is based on SFPTotal Mini with added extensions to transceiver ports. For working with GBIC, XFP, and QSFP transceivers included the additional power plans, as well as control elements.

The SFPTotal Plus connects to PC via USB interface through which performed control and power supply of transceiver. To connect a high-power transceivers can be used by external power adapter 5V DC.

Application

Programmers SFPTotal are used to solve next tasks:

• Programming SFP/SFP+, XFP, QSFP, GBIC 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 Plus board to your PC using micro USB Type B cable
2. Install drivers for SFPTotal Device
3. Download application SFPTotal Wizard
4. Start SFPTotal Wizard
5. Insert transceiver to the programmer port
6. Reading transceiver's memory

Elements

Listing of elements placed on circuit board of SFPTotal Plus programmer.

1. Transceiver ports

P2 - SFP, SFP+ port

P11 - QSFP, QSFP+, QSFP28 port

P9 - XFP port

P7 - GBIC port

2. Power supply plans

P1 - power supply of SFP port, a pair of 3.3 V for VccT and VccR pins.

P17, P16, P15 - power supply of QSFP port, 3.3 V for Vcc1, VccTx and VccRx pins.

P12, P14, P13, P10 - power supply of XFP port: 3.3V, -5V, 5V and 1.8 power supply plans.

P8 - power supply of GBIC port, switch between 3.3V or 5V. For default, closed in 3V3 position.

3. Jumpers

P3 - low power mode, keep closed to disable low power mode (TX enable).

P4 - RS1 (position 1-2) and RS0 (position 3-4) pins.

P18 - QSFP ModSelL

The ModSelL is an input pin. When held low by the host, the module responds to 2-wire serial communication commands. The ModSelL allows the use of multiple QSFP modules on a single 2-wire interface bus. When the ModSelL is “High”, the module shall not respond to or acknowledge any 2-wire interface communication from the host. ModSelL signal input node must be biased to the “High” state in the module.

INF-8438

Notice: The programmer automatically switches the contact to "Low" level when performing read and write operations on the data bus.

P19 - QSFP ResetL

P20 - XFP ModDeSel

The Mod_DeSel is an input pin. When held Low by the host, the module responds to 2-wire serial communication commands. The Mod_DeSel allows the use of multiple XFP modules on a single 2-wire interface bus.
When the Mod_DeSel pin is “High”, the module shall not respond to or acknowledge any 2-wire interface communication from the host. Mod_DeSel pin must be pulled to VCC3 in the module.

INF-8077i

Notice: The programmer automatically switches the contact to "Low" level when performing read and write operations on the data bus.

P21 - XFP PDOWN/RESET

This is a multifunction pin for module Power Down and Reset. The P_Down/RST pin must be pulled up to VCC3 in the XFP module.

INF-8077i

4. Interfaces

P22 - I²C databus, logic level 5V

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 Plus.

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:

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
