The ServerGuard Adapter is a
standard IBM type-3 Micro Channel card size (3.475
inches X 11.500 inches). The PC board contains
10 layers, three voltage, one ground, six signal
planes. ServerGuard FrontP/N 61G3628

Jumpers Password Override Jumper
[SP1?] The administrative password protects
functions such as changing passwords, changing power
controls, setting error thresholds, and updating code in
flash memory. When the jumper is on pins 2-3, it is in the normal operating position. To override the admin password, jumper pins 1-2. Restore the jumper to 2-3 to protect the new password. Ed.

U44 Mystery Power Planes The ServerGuard has three separate power planes, Vcc, Vbb, and Vbat. Vcc Power Plane Each time the system +5v goes below 2.5v, an internal interrupt (AD_INT3) is generated to alert the adapter microprocessor that power has been removed. Vbb Power Plane It provides power for most of the
computational logic on adapter (microprocessor, memory,
and ADC). When the battery is the power source, Vbb
voltage can be turned off with the power-kill bit; this
bit has no effect when the system +12v is present. Battery Voltage Plane (Vbat)
Logic on the Vbat plane is always active
and cannot be turned off, as long as the 7.2v battery
pack has power. The functions on this power plane include
the Shutdown, Power-Kill, Suicide, and Low-Power Enable
registers, the LED and it's controls, the control logic
for the Vbb power plane, and the voltage regulator for
the Vbat power plane. Serverguard Functions Is it a PCMCIA Adapter?

MESSAGES, STATISTICS AND LOGS
ServerGuard
information is displayed graphically, and more detail is
available at the click of the mouse. The ServerGuard
option makes system operational statistics, such as CPU,
memory, and disk capacity utilization, available in real
time. NetFinity for OS/2 displays a record of the last
10 seconds to 10 days (user selectable) for each
statistic. The statistics can be stored to disk for
long-term storage and analyses. ServerGuard records all critical events in a non-volatile (NVRAM) log, easily accessed for review. Because the ServerGuard is battery-backed, the log can always be accessed even if the server is not operating. The ServerGuard allows reboot and power on/off control
of the server system. ServerGuard Functions
Monitoring and Controlling
Resources Sleep Mode Running ServerGuard under OS/2 For anybody who has one, here's what I did to get it working in OS2. Download and install Netfinity 5.06 for OS/2 from IBM's site. Once that's running, download OEP128A.EXE as well. Create the disk, then run the install program. Change the source from c:\netfinity to a: and choose the option to install for local administration and then reboot. When you run Netfinity, you'll see the Serverguard option and from there you can look at the logfile and set up settings for it. It works without the power supply, but is limited of course. The power supply for the IBM ISA remote management adapter is the same thing and they can be found on ebay. External Power Control Box Battery Pack PN 61G3629 A rechargeable 7.2v Ni-Cad battery pack is used to power the adapter logic when the system is powered off. The EPCB recharges the battery while the adapter is in sleep mode. When fully charged, it provides about 50 minutes of power to the adapter, or if the adapter is in sleep mode, it provides about 60 hours of power. When fully discharged, it takes about 24 hours to fully recharge. The adapter monitors the battery voltage, and when the voltage reaches a predetermined threshold, it takes the specified action (eg. go to sleep). Battery
Pack Construction ServerGuard Battery Pack
Layout (New battery needs 24 hours to
charge) 6x Sony Cadnica N-600AAK [1.2v / 600mAh ] Klixon 3-S Battery Pack Plug: MX 20D [sounds Molex-ish] Power Control Box P/N 71G6222 (used also with ASMA) The External Power Control Box (EPCB) controls
the AC input into the system power supply. A cable
provides a control path from the ServerGuard to the
EPCB. The system power cord is plugged into the EPCB,
and the EPCB is plugged into an AC source. The
ServerGuard then controls the system power by signalling
the EPCB to turn power to the system on or off. The EPCB has a power override switch.
When the switch is closed (on), AC power is provided to
the system regardless of the ServerGuard controls to the
EPCB. When the switch is open, the power to the system
is determined by signals from the ServerGuard. The EPCB has two LEDs. The power-status
LED reflects the state of LED1 on the ServerGuard, and
the cable-attached LED shows if the control cable from
the ServerGuard is connected correctly. UPDATE: The revised Serverguard has LEDs 3, 1, 2. LED 2
flashes with Power Status LED on the EPCB.
IBM PS/2 ServerGuard Features
EPCB Connector OVRIDE Pin 1
Override-status signal is an output to adapter that
indicates state of the power-override switch. A high
level indicates the switch is open, low indicates
closed. EXTPWR Pin 2
External-power signal is an output to adapter and is
used to recharge 7.2v battery pack. SHUTEN Pin 3
Shutdown-enable signal is an output to adapter and is
grounded in EPCB. LEDON Pin 5 This
is an input from adapter that controls power-status LED
on the EPCB. It is controlled through Adapter Control
Register 1. CARD_DETECT Pin 6
This is an output to adapter that indicates whether EPCB
is connected correctly. It is pulled low by EPCB. The
state of this signal is indicated in EPCB-status
bit. GOOD_CABLE Pin 7
This is an input from adapter that controls the
cable-attached LED on the EPCB. It is lit when the
signal is low. EPCB_CLK Pin 8 This is an input from adapter that clocks the data on DCON. The data is transferred on the rising edge. It is controlled by the EPCB Control register. My
Power Cord was Bobbitted! Note- My 10 pin
header numbering is off. I do know that the "N" is
correct. N is pin 7.

0275xx Errors The Serverguard's series of error messages is HERE POST
or configuration errors with ServerGuard installed
Once the ServerGuard adapter has
successfully completed POST, it will function normally,
without further exposure to the problem until the system
is once again powered on (POST is run again). Problem Isolation Aids Inspect the
ServerGuard card for a component (chip) at location U44.
If this module is missing, the adapter is NOT exposed to
this problem. The location of U44 is printed on the
card, but the lettering is very small. Refer to the
following diagram for the location of U44: Backside of the ServerGuard
Adapter Fix This problem is being corrected in current production. A new version of the ServerGuard adapter is available under FRU P/N 06H8091. Ed. My SG doesn't match the FRU or P/N. The two chips to the right of U44 (above) look to be EPROM, while my SG has flash. I do have a U44 close to that location, but I will have to install the SG to confirm my hunch.
