Cable Installation

All cables can be inserted or removed with the unit powered on.
 To insert a cable:
press the connector into the port receptacle until the connector is firmly seated. The LED indica-
tor, corresponding to each data port, will light when the physical connection is established. When
a logical connection is made the relevant port LED will turn on.
 To remove a cable:
disengage the locks and slowly pull the connector away from the port receptacle. The LED indi-
cator for that port will turn off when the cable is unseated.
For more information about port LEDs refer to Section 3.3.1.6, "Port LEDs," on page 56.
Do not force the cable into the cage with more than 40 newtons / 9.0 pounds / 4kg
force. Greater insertion force may cause damage to the cable or the cage.

2.6.1 Using a Breakout Cable

Only internally managed switches, in Ethernet switch mode, support splitting of the
data stream.
A 40GbE port can be split to 4 ports (or less) of 10GbE each, by using a Mellanox breakout
cable.
In some switches not all ports can be split. When using a port to split a data stream into 4-10 Gb/
s data streams one of the other ports on the switch will be disabled, unmapped from the switch.
When using this feature you should login into the MLNX-OS® CLI and configure the individual
ports to be 'split-2' or 'split-4'.
For further information and guidance, it is recommended to read more about Mellanox breakout
cables on the Mellanox Community
