3.1.1 Data Interfaces

The data interfaces use QSFP28 connectors. The full list of interfaces per system is provided in
Table 3, "Speed and Switching
QSFP28 cable or connector for 25/40/50/56/100GbE, or 1/10/25GbE when connecting through
Mellanox QSFP28 to SFP28 (QSA) adapters, hybrid or split cables. The systems offer High
Power/LR4 transceivers support (up to 3.5W) in all QSFP28 ports. Some QSFP28 ports support
4.5W transceivers, as detailed in the following table:

a. 4.5W high power modules are supported on MLNX-OS from version 3.6.3004 onwards.
b. When using 4.5W modules on the specified four ports, only cables and transceivers with lower power
than 1.5W can be used on ports 51, 52, 53 and 54. See illustration in
The SFP28 ports in SN2410 support Level II (up to 1.5W) transceivers.
