RLC Card
The RLC card is the processor card. It contains all the necessary hardware to maintain
the robotics, interfaces, servo and vision control, and the door/CAP sensor status.
The card stores the library capacity information and the volume serial numbers (also
called VOLID) of the cartridges in the library storage cells.
Interface Cards
The RLW card is the LVD SCSI interface card. The MPU2 card is the Fibre Channel
interface card.
