"RMP is inoperable." Message During Boot
Server 195/295 systems with RMP boards at rev 28 or
lower. Replace RMP board ver 28 or lower with FRU
P/N 92F0200 (revision 29 or higher).
Warning! DO NOT HOLD
DOWN FOR MORE THAN 2 SECONDS. (More than 2 seconds may result in severe system
Errata: The WD16C552 chip supports up to 512K baud!
No keyboard controller, the only KB controller I have seen is on the CPU IP board.
There are two pairs of NPN transistors, a pair of 2N5089 and a pair of 2N3904. I don't have an ideal, maybe an amplifier? There is a load of PALs, GALs, and simple logic chips all over this board. Difficult to figure out what does what...
MASS/2 Features (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:
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.
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.
