VMEbus and VXIbus Specifications.
• Surface mount construction and no sockets for maximum
reliability.
Basic Monitor Specifications
(Applicable to all three mainframes)
Indicators: • Power-on or Standby status
• Power supply output voltages
monitor
• Power supply temperature monitor
• Fans status monitor
• Backplane activity monitor
• Backplane SYSFAIL monitor
Switches: • On/Standby
• Fan Mode: Switches all fans
between Full Speed and Variable
Speed modes
• Reset: Asserts backplane signals
SYSRESET and ACFAIL
Diagnostic connector: • Output all 7 backplane voltages
for monitoring
• Output +5 V and +12 V for remote
applications. 1A max each
• Input +5VSTDBY to backplane. 1A
max total for pins 5 and 18
• Remotely operate On/Standby
• Power supply temperature output
• Reference temperature output
• Fans OK output, same as Fans
indicator
• Backplane voltages OK output
• SYSRESET*, input or output
• ACFAIL*, output
• Ground
All other slots blocked. Airflow decreases as additional
slots are opened.
• Performance shown for Worst Slot (slot 2). Airflow is
greater in all other slots.
• Fans on Full Speed. Minimum airflow is approximately
50% with fans on Variable Speed.
• Air Filter Kit not installed. Airflow is reduced
approximately 10% with clean air filters installed.
• Measurements taken at 1,500 m altitude.
