Power-on/off button

Press this button to turn on the amplifier. Incorporates a power status LED that is green when OP8110 is powered-on.

To power down the amplifier, please hold the power button until the “CFG” LED turns off (approx. 2.5 sec) and then release it.

In the unlikely event that this shutdown method is unsuccessful,

press

a hard reset is needed and it can be achieved in 2 ways: Shut down the amplifier auxiliary power (12VDC) by shutting down the 120V/220V inlet power (unplug the power cords or switch off client circuit breaker/switch). Press and hold the power button until power down is achieved (approx. 6 sec) - (not recommended! - only if requested by OPAL-RT support).
Ethernet port	Ethernet port used to interface directly with the OP8110 from a computer through TCP/IP. Must be used to update the bitstream of the amplifier.
Mini-USB port	Serial communication port used to interface with the OP8110 as an alternative when Ethernet is not available.
SFP ports	Optical 2 Gbps SFP ports for real-time control of the OP8110. Two ports are available: Leftmost port: used for debug purposes Rightmost port: used as the primary real-time control interface. Refer to SFP Communication Protocol section below for more details.
LEDs	Status LEDs, refer to LEDs section below for more details.

12 Auxiliary supply connector	Supply input for the control circuitry of the OP8110.
Outputs	High-voltage outputs of the amplifier. Each OP8110 group has 3 outputs, each of which has its dedicated neutral point. Refer to OP8110 Power Stage for more details.
DC inputs	500 V_DC inputs for the OP8110's power stages. Each OP8110 group has its isolated DC input, refer to OP8110 Power Stage for more details.
GND screw	Must be connected to electrical ground for safety purposes.
Remote sense connectors	Remote sense input connectors which can be used to compensate for voltage drop of the test setup - reserved for future implementation.
Optical synchronization connectors	Optical links (Rx and Tx) to synchronize switching between OP8110 units to get better performance. OP8110s can be daisy-chained (Rx of a unit connected to Tx of another unit) in any order as long as one unit in the chain has its Rx unconnected. The OP8110s will automatically configure their synchronization interfaces (master/slave) to match with the connected cables, no user configuration is required.

Warning
CAUTION The OP8100's synchronization cables should neither be connected nor removed during amplifier operation. Doing so mayresult in both damage to the amplifier and voiding of the warranty.

LED Label	Color	Description
STATUS	Green Red	Indicates that the unit is powered up and functioning properly. Indicates a system error.
CONFIG	Green	Indicates that FPGA programming is complete.
USER	Green Orange	User configurable to display a condition specified by the user. If undefined, displays no status.
SYNC TX	Green	Reserved for future implementation
SYNC RX	Green	Reserved for future implementation
SYNC M/S	Green/Orange	Should be green when using an external simulator to control the OP8110
SFP_0 Tx/Rx	Green/Orange	Green: SFP channel is correctly configured
SFP_1 Tx/Rx	Green/Orange	Green: SFP channel is correctly configured
