Parallel Port
The parallel port is used almost exclusively for printers, but is compatible with any peripheral
device designed to interface with a standard Centronics-type parallel port. The FDC37C932 includes
the system's parallel bus controller. Only shielded cables should be used with the parallel port
(DB-25). Refer to page 58 for information about the FDC37C932 and its parallel port functionality.

LCD Board (MSMT344)

The LCD board consists of a four-line display screen, soft-touch buttons and status LEDs that allow
users to monitor system and disk section status (RAID systems only). The display screen reports
various system status and events in a software-independent manner. The 550 Watt power supplies
feature an always on +5V output. System status information is available if the system is powered off,
as long as the system is plugged in and the circuit breaker switch is in the ON position. If the system
uses the 539 Watt power supply, status information is only available when the system is powered on.
The LCD board functions as a central resource through which system power and status signals are
routed. The system monitor accepts status inputs from the power supply, internal disk section,
temperature sensors, safety interlocks, and fans, and generates the appropriate alarms and alerts.
