2.6 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.

2.6.1 Using a Breakout Cable
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 Website .
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.
Only internally managed switches, in Ethernet switch mode, support splitting of the
data stream.
