A related feature of ASM is the remote diagnostic
management (RDM) that permits system diagnosis from a remote site
through a modem. The RDM facilitate the fixing of detected
problems, changing system configurations or rebooting in the event of
system failure.
1.1.5 Redundant Power Supply Subsystem
The system comes with a power backplane that holds up to three
400-watt power supply modules. The power subsystem supports a
redundant configuration such that even if one power supply fails, the
remaining two continues to work together to supply the 800-watt
requirement for a fully-configured system.
Two important segments of the power subsystem configuration are
the charger board and battery box. Together, these two components
function like an uninterruptible power supply (UPS). Providing an
additional support to the three 400-watt power supply modules, the
battery automatically charges whenever the system is on. The
battery gives a fully-configured system the ability to run continuously
through short interruptions in wall power or for a maximum of six
minutes in the event of total AC power shutdown.
1.1.6 Security
The system housing comes with mechanical security locks on both
the front panel and the side panel preventing unauthorized access to
the internal components and system use.
The system BIOS secures the CMOS data and other system software
with power-on password, keyboard password, setup control, disk drive
control, and monitor control.
