upgrading all switches in the stack, save the configuration (using the write memory command) and reload the stack to activate the new FTOS version (using the reload command).

System Initialization

The Master Switch initializes the stack using the last saved system configuration file.

If you change the stack configuration, be sure to save the configuration file. The Master Switch automatically distributes the configuration file to the member switches. If the Master Switch later becomes unavailable, the Standby Master becomes the new Master Switch and configures the stack with the latest configuration synchronized from the Master Switch.

In case of a split stack in which the Master Switch in one of the new stacks was previously a member switch, the last saved configuration on the original stack is used to configure the new stack.

Splitting 40GbE QSFP+ Ports into 10GbE SFP+ Ports

The MXL 10/40GbE Switch supports splitting a 40GbE port on the base module or a 2-Port 40GbE QSFP+ module into four 10GbE SFP+ ports using a 4x10G breakout cable.

NOTE: By default, the 40GbE ports on a 2-Port 40GbE QSFP+ module come up in 4x10GbE (quad) mode as eight 10GbE ports. On the base module, you must convert the 40GbE ports to 4x10GbE mode as described below.

Before you attach a 4x10G breakout cable to a 40GbE QSFP+ port, ensure that the following requirements are met:

•A 4x10GbE QSFP+ port cannot be used for stacking.

•In order for a 40GbE port to operate in 4x10GbE mode, you must enter the stack-unit port portmode quad command.

FTOS(conf)# stack-unit unit-numberport port-numberportmode quad
