is on the CPU IP board.
There are two pairs of NPN transistors, a pair of 2N5089

amplifier? There is a load of PALs, GALs, and simple logic
chips all over this board. Difficult to figure out what
(Maximum Availability and Support System/2)
Integrated software allowing monitoring, controlling,
tuning, and recovery of 295. Allows 295 to be
geographically distributed while permitting
comprehensive, centralized control with mainframe-like
remote administration. Features:
Failure recovery without human intervention (most cases).
Operation even when 295 powered down (RMP with battery).
Concurrent access by multiple users.
Access via console, across LAN (local), via modem
Continual monitoring of CPU, memory, disk,
network, and swapping level utilization via real-time
bar graph, and 1 hour history in RMP RAM, and historic
logs on disk.
Continual monitoring of temp, PSU voltage,
single bit memory errors, network errors.
Configuration details: processors, memory, SCSI,
arrays, spares, RMP, UPS status, adapters
Alarm and threshold selection with automatic
dial out capability for events like disk failure, disk
full, reboots, shut downs, memory errors, over
temperature, power low/high, and network errors.
Scheduled power down and power up; remote rebooting.
SAA-compliant graphical user interface (hierarchical).
Access to network operating system logs and server logs.
Multilevel password based security; G File transfer capability.
Preinstalled on Server 295.
