1. Maximum port values are uni-dimensional, may require the use of break-outs and are subject to transceiver/cable capabilities. Detailed information can be found here.

2. Where supported by EOS, each system supports a maximum number of interfaces. Certain configurations may impose restrictions on which physical ports can be used

3. Typical power consumption measured at 25C ambient with 50% load on all ports

4. Rear to front airflow is subject to 35°C max ambient temperature and transceiver power restrictions, requires EOS 4.29.1 and High Speed fans (FAN-7011H-R).
