General Specifications

Network interface

Characteristic	Description
IEEE standards	IEEE 802.3 100 Gbit/s Ethernet IEEE 802.3 40 Gbit/s Ethernet IEEE 802.3 25 Gbit/s Ethernet IEEE 802.3 10 Gbit/s Ethernet IEEE 802.3 1 Gbit/s Ethernet
Type of physical interface	QSFP28
Number of physical interfaces	2 ports
Supported pluggable modules	QSFP28 QSFP+ SFP28 SFP+ SFP Note: Which of the supported modules are relevant depends on the link speeds supported by software (see Step 6). Note: QSFP28 100GBASE-PSM4 can break out to 4 SFP28 25GBASE-LR. Note: QSFP28 100GBASE-SR4 can break out to 4 SFP28 25GBASE-SR. Note: QSFP28 100GBASE-CR4 can break out to 4 SFP28 25GBASE-CR. Note: QSFP+ 40GBASE-PSM4 can break out to 4 SFP+ 10GBASE-LR. Note: QSFP+ 40GBASE-SR4 can break out to 4 SFP+ 10GBASE-SR. Note: QSFP+ 40GBASE-CR4 can break out to 4 SFP+ 10GBASE-CR. Note: QSFP+ 40GBASE-LR4 pluggables cannot be used with breakout cables, as they interface to single-mode fibers where the four 10 Gbit/s lanes are multiplexed and therefore do not allow mechanical breakout. Note: SFP28, SFP+ and SFP pluggables can only be used together with a pluggable module adapter (PMA) enabling SFP28, SFP+ and SFP modules to be plugged into a QSFP28 port.

Pluggable Modules

For information on modules that have been qualified by Napatech for use with the SmartNIC, see accessories.napatech.com.

Pluggable module adapter

The only pluggable module adapter (PMA) that can be used to enable SFP28, SFP+ and SFP modules to be plugged into a QSFP28 port is MAM1Q00A-QSA28 from Mellanox Technologies, which is shown here:

Electrical rating

This table shows the power consumption for an NT200A02-SCC SmartNIC including 2 × QSFP28 modules.

Auxiliary Power Connector Used	Supply Voltage			Supply Current			Supply Power
	PCI Express		Aux. Power	PCI Express		Aux. Power	PCI Express		Aux. Power	Total Max.
	3.3 V [in V]	12 V [in V]	12 V [in V]	3.3 V [in A]	12 V [in A]	12 V [in A]	3.3 V [in W]	12 V [in W]	12 V [in W]	[in W]
No	3.3	12	-	1.5	5.8	-	5.0	70.0	-	75
Yes	3.3	12	12	1.5	-	5.8	5.0	-	70.0	75

Power is measured with capture of a stream with 80% load of 300-byte frames. A sustaining load of 80% with 300-byte frames is representative for maximum real-life scenario. The actual power consumption depends on the FPGA software payload.

The SmartNIC is Class III equipment for supply by SELV circuits only.

Port numbers

Port numbers	0 and 1
Location

Note: On an NT200A02-SCC running at 8 × 10 Gbit/s, the port ID for each 10 Gbit/s port reflects the corresponding 40 Gbit/s port (0 or 1).

Note: On an NT200A02-SCC running at 4 × 25 Gbit/s, the port ID for each 25 Gbit/s port reflects the corresponding 100 Gbit/s port (0).
