Product Description

LCC circuitry provides the following functions:

■

System fault detection

■

Disk address generation

Caution

If an LCC fails, do not remove it from the disk system until you
are ready to replace it with a new one. The failed LCC should
remain installed to assure proper cooling for the disk system.
