POWER FAIL RECOVERY
POWERMON II UPS SOFTWARE for NCR 4091, UPS on NCR S20, S40, or 4300 running UNIX SVR4 03.02.xx
1. NOTE:
Throughout this FECO a SPACE in a string is shown by a Ñ
All other spaces are purely cosmetic.
2. INTRODUCTION
Basic Installation procedures for PowerMon II with the NCR 4091 UPS on an NCR S20, S40 or
4300 running Unix SVR4. Ver 03.02.xx to provide a Power Fail Recovery facility.
On the NCR 4300, PowerMon II is designed to be installed onto a system that does not have the
internal UPS system fitted.
Power Fail Recovery is known not to function on an NCR 3416, 3259 or 3269.
The correct version of the PowerMon II software comes at present in a box with K519 in its part
number and the diskette has MP-RAS Ver 3.2.3 written on it.
Any other part number or version may not work.
3. If
Powermon II is being installed onto an existing installed system, then a Project Plan must
be produced and approved prior to this
installation. Before installation of Powermon II, ensure that the customer has two
full
verified file saves.
4. Installation and configuration consists of the following:
Checking & setting System
Setting up the serial port
Installing the communications cable
Installing the utility
5. SYSTEM
5.1. Dump Slice
On the
system ensure that there is a dump slice on the disk, and that its size is adequate for
the amount
of memory in the machine.
5.2. The ups_status File
The ups_status file contains UPS-OFF or UPS-ON. If the file contains UPS-OFF; at
power fail it attempts to log out of UniVision, down dating the other UV control files as it
exits. If it completes this task successfully, the process returns to the UNIX login. If
ups_status does not exist the system defaults to UPS-OFF.
The ups_status file is located in the ./UniVision/univision/admin directory.
This means that for a system with a powerfail recovery strategy, this file must contain
UPS-ON. If it does not, in the event of a failure all processes are returned to UNIX login.
To configure ups_status, login to SYSPROG and enter ! <CR>. At the UNIX prompt ($)
enter UVups <CR>.
If ups-status does not exist the system prompts:
Current ups_status setting = xxx.xxx
Do you want to continue with the change file? (Y/N):
Enter Y <CR>
File "univision/admin/ups_status" not found or of zero size
Do you want to create the file? (Y/N)
Enter Y <CR>
If you enter Y the file is created and the system prompts you as follows:
Enter "0" to set UPS_OFF or "1" to set UPS-ON:
If you enter 1 you get the following message:
New setting of "ups_status" = UPS=ON
NOTE For Orderley Shutdown, the ups_status file must either not exist or if it does it must be set to UPS_OFF.
6. SERIAL PORT
The serial port must use tty01
Ensure that no service is running on the port. If there is one running then remove it.
Enter pmadm Ñ -l Ñ | Ñ pg <CR> to display Port Services.
7. STRATEGY
Ensure that the strategy is Power Fail Recovery.
To display the strategy in root
Enter strategy and ensure response is Current Strategy is Power Fail Recovery.
If it is Orderly Shutdown, then change it to Power Fail Recovery.
Enter # strategy Ñ -s <CR>
8. COMMUNICATIONS CABLE
Connect the communications cable between the UPS and the NCR 3000 COM 2 port.
This should be the correct type of cable for the appropriate UPS used.
For Powerware Prestige (NCR4091) use Cable Type JT or JU1.

12. TEST POWER FAIL RECOVERY
12.1 Ensure that several screens are logged into an application.
12.2 SHORT MAINS FAILURE
12.2.1 Switch OFF the mains input into the UPS, to simulate a short mains failure.
12.2.2 Check that: the message "ON BACKUP POWER" is broadcast to all
screens, with a time
when the system

screens with a time when the system will
shutdown. After this
time, on the system console, it should show it transferring memory slices, then after this
the
statement,
"SHUTTING OFF UPS".
