The MCB is the primary point of intelligent management in the library.
3 The MCB stores firmware and configuration data for itself as well as most
other intelligent components in the library. It also contains the LMC,
which enables local or remote users or hosts to operate, configure, and
monitor the library. The MCB collects status information on other
components in the library and issues notifications when problems occur.
The RCU provides robotics intelligence that controls accessor movements
3 and functions, including picker, pivot, and reach actions. It receives
commands from hosts or users by way of the MCB.
The LMD monitors wiring, fuses, and relays within the library. It
3 regulates power levels and performs other power-related functions, such
as disabling robotics when a library door opens.
The I/O management unit is an optional component that provides
connectivity and data path management to a SAN fabric and the hosts.
The I/O management unit houses up to six FC I/O blades, which provide
FC connections for the Fibre Channel drives in the module. (The control
module and each of the expansion modules can contain up to 12 FC
drives.) The I/O management unit performs all tape drive and library
host communication functions in a library that is attached to a SAN.
The I/O management unit supports two types of blades: the control
management blade (CMB) and the FC I/O blades, as shown in
on page 88.
