Linecard Expansion Module

The LEM is a pluggable expansion module for the IBM SAN32C-6 Switch. The LEM has 16 32-Gbps ports that are automatically detected and enabled by the switch. The ports may then be used when the correct port licenses are installed.

The LEM blank module must be installed if the LEM bay is empty when operating for longer than several minutes to provide correct airflow. If the airflow is inadequate the preset temperature thresholds will be exceeded and the system will automatically shut down to prevent permanent damage.
