Power supply
Single 5V power supply with minimum current capability of 1.5A is recommended to power on the board.
DIP-Switches and Push Buttons
There is two reset switchs on the board (S1 and S6). The S6 is a soft reset button (SRST) that is not directed to CPLD chip. The S1 signal is connected to CPLD chip and is used in firmware code to create a reset signal.
| Signal | Designator | Connected to | Active Level | Description |
|---|---|---|---|---|
| SRST | S6 | B2B JB2 pin 56 | Active low | |
| S1 | S1 | CPLD chip pin 114 | Active low |
| Dip Switch S2 | Signal | Position ON | Position OFF | Connected to | Description |
|---|---|---|---|---|---|
| S2-1 | MIO0 | MODE pin ( B2B JB1 pin 31 set to '0') | MODE pin ( B2B JB1 pin 31 set to '1') | CPLD chip pin 94 / B2B JB1 pin 88 | |
| S2-2 | JTAGEN | Module FPGA JTAG access ( if S2-3 ON) | Module CPLD JTAG access (if S2-3 ON) | CPLD chip pin 120 | |
| S2-3 | CM0 | Module FPGA/CPLD JTAG access (depends on S2-3) | Carrier CPLD JTAG access | CPLD chip pin 76 | |
| S2-4 | CM1 | PGOOD signal set to '0' | PGOOD signal set to '1' | CPLD chip pin 75 |
DIP Switches /Push Buttons
There is no DIP switch on the TEM0007 module.

I2C to GPIO
Such signals same as NOSEQ can be read or written via i2c commands in linux console. For more information about it refer to TEB2000 CPLD#I2C to GPIO
LEDs
There are six LEDs which can be used for variant purposes.
| LED | Designator | LED Status | Condition | Description |

| OFF | Otherwise |
* This LEDs exit on the ethernet socket (J14A).
Carrier LEDs
Note: The TEM0007 module has no LED.
JTAG/UART
JTAG and UART connections are available through micro USB connector. MIO14 is driven by BDBUS0 (FTDI RX). BDBUS1 (FTDI TX) is driven by MIO15 . MIO13 is driven by UART_TXD. UART_RXD is driven by MIO12.
