"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).
 
Note: RMP firmware must match the level being replaced to assure system compatibility.
 
Temporary work-around:
     Reset RMP by pressing (only once *) the white button on top of RMP next to red LED and reboot system. If error message goes away, the cause was a drained battery on RMP.  Determine the cause of the drain.
 
Typically the drain is a terminal or modem attached to the RMP without system power.  Once battery is recharged, the error message will no longer occur.

Warning! DO NOT HOLD DOWN FOR MORE THAN 2 SECONDS. (More than 2 seconds may result in severe system damage).

RMP Components
N80C186XL, 5(x) 84256A (total of 1,256K memory), WD16C552 (serial and parallel), and 5(x) MAX232CPEs serial line drivers. Sensing components are an ADC0808N, LM34CZ temp sensors, TL7705CP Supply Voltage Supervisor, and a DS1286 Watchdog.

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:
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 (remote).

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.
