installed, the library will continue to operate if one module fails. The remaining PSM
will power the RLS-8350 indefinitely. The library and tape drives will continue to
function, uninterrupted by the failure and subsequent replacement of the failed PSM.
A green "power good" LED indicates that a PSM is operating properly. A failed PSM
causes an alarm condition that will result in e-mail notification by the Q-Link remote
library manager.
All PSMs supply regulated 24-volts DC to the RLS-8350. The unit is powered from AC
mains of 100- to 240-volts, 50 or 60 Hertz.

FastPass Elevator Expansion Option
RLS-8350 rack mounted tape libraries easily expand capacity and data delivery
performance to keep pace with rapidly growing data protection and data archiving
requirements. Each library can be equipped to pass tapes vertically from one unit to
the next when installed in an industry standard 19-inch EIA equipment rack.
The FastPass elevator expansion option passes tapes from unit to unit. The
mechanism installs from the rear of the rack and fits entirely within the form factor of
the libraries.
The FastPass option can be installed by an end user, and the system is completely
self-calibrating. The elevator option requires no additional power or cooling, and does
not reduce the number of tape drives housed in each library module. The fast pass
modules use a tape drive slot, reducing the possible number of tape drives by two for
each pair of libraries that are connected.
Each RLS-8350 library can be expanded by adding one to three RLS-8560 or RLS-
85120 libraries below it, enabling the total configuration to support up to 19 tape
drives and up to 410 tape cartridges.
