Power managers can support up to twenty-six boards in a
chain of boards. Each board has its own set of four intelligent
power modules (IPM’s). The power manager has a power
control screen for each of the boards in the power manager
chain. Some modules have on board and therefore a single
power control screen. Other have multiple boards and there
fore multiple power control screens (one for each board).
Each power control screen is considered a different page and
each power control screen controls four IPM’s. The page
currently being viewed is displayed in the upper right corner
of the screen, as is the total number of pages. The page
currently being viewed is also indicated by the name in the
page ?eld in the lower left of the screen. A help line at the
bottom indicates what key presses are available for speci?c
functions,
C) mnd puts the power manager back into Command Prompt mode at
the “power manager:” prompt.
E) dit is used to edit ?elds enclosed by square brackets.
When “E” is pressed, the cursor moves to the end ofthe
current entry. The backspace key erases one character.
Press Enter or Tab when done editing the ?eld.
“N”) eXt displays the neXt Power Control Screen page.
P) revious displays the previous Power Control Screen page.
“Q”)uit ends the current session.
S) pace—Bar to Select indicates that the space bar is used on
non—editable ?elds to toggle between the predetermined
settings. The space bar is also used on the status line to
change the power state of a port to the state of the current
cursor location (either On or Off). The plus and minus keys
can also be used to toggle forward or backward through the
predetermined settings.
A Port Name is an eight character descriptive ?eld for the
device plugged into the IPM. This ?eld is used both as a
description and as a parameter to the ON, OFF, REBOOT, and
STATUS commands.
A Control Status of the IPM is shown by a character in the
On or Off ?eld. An “X” is displayed if the port is accessible
remotely. An asterisk is displayed if the IPM is locked on by
the administrator, or if the IPM is not accessible by the current
password level.
To change the power state of an 1PM, the cursor is moved
to the desired state (On or Off), and the space bar is pressed.
The “X” will move to the new state, indicating the power
changed to that state.
A user can press “R” when in the On or Off ?eld to reboot
the port. If the port is already off, it will turn on immediately.
If it is on, it will turn off, delay, then turn back on. The delay
before turning back on is either 15 seconds, or the Minimum
Off Time, whichever is greater. During the reboot delay, an
“r” is displayed in the Off ?eld, indicating the port is going to
reboot.

When in the On or Off ?eld, a user logged in with the
administrative password can lock or unlock a port by pressing
“L” to lock, or “U” to unlock. A locked port will display an
asterisk in the On or Off ?eld, and cannot be controlled by a
general user is a it can be unlocked by the administrator.
The Module Status is an informational ?eld that displays
the current status of the associated 1PM as reported to the
power manager. If the IPM is working correctly, this ?led will
display “Normal”. If the power manager is unable to commu
nicate with the associated 1PM this ?eld will display “No
Rspns”. If the IPM is set to “On” and the power manager
detects the associated 1PM is not on, this ?eld will display
“OnS Fail”, e.g., for On Sense Failure. If the IPM is set to
“Off” and the power manager detects the associated 1PM is
on, this ?eld will display “Off Fail”. Note that power manag
ers equipped with these “ON SENSE” IPMs can be con?g
ured to generate SNMP traps when On Sense errors are
detected.
The Device Load is an informational ?eld that displays the
amount of current in Amps that is ?owing through the asso
ciated 1PM. This ?eld is signi?cant if the power manager is
equipped with the Server Technology “LOAD SENSE” IPMs
that are capable of sensing the load going through the 1PM
and relaying this information to the power manager. If the
power manager is not equipped with these “LOAD SENSE”
IPMs this ?eld has no meaning and ““N”/A” is displayed.
This ?eld will display the current in Amps when current is
?owing. If the associated 1PM is set to off and no current is
?owing (this is the normal case), the ?eld will display “Not
On”. Power managers equipped with “LOAD SENSE” IPMs
can be con?gured to generate SMMP traps when load sense
values fall outside a user con?gurable range.
The Minimum-On Time is the minimum amount of time
that an 1PM will stay on before it can be turned off by actions
at the power manager command prompt. Manual actions in
the Power Control Screen On or Off ?elds, however, are
always immediate, ignoring this value. The default is 0.
The Minimum-Off Time is the minimum amount of time
that an 1PM will stay off before it can be turned on by actions
at the power manager command prompt. Manual actions in
the Power Control Screen On or Off ?elds, however, are
always immediate, ignoring this value, except in the case of a
reboot. This ?eld determines the off delay time of a reboot, if
greater than 15 seconds. The default is 0.
The Shutdown Delay is the amount of time the power
manager will delay when a Power Off command is issued for
an 1PM before the IPM is actually set to the Power Off state.
This delay is designed to allow a Power Off signal to be sent
to an operating system on a machine that is attached to the
IPM. Pressing the space bar when positioned to this ?eld
changes this value. The value can be set from “Disabled”
(e.g., no delay) to a series of choices ranging up to an eight
minute delay. Please refer to the power manager Shutdown
and Windows-NT UPS Service Con?guration section of this
manual for information on con?guring automatic operating
system shutdown.
The Wake-Up State is the state that the IPM will be in when
controller power is turned on or when controller power is
restored after a power outage. The options are ON and OFF.
The default is ON.
The Group ?eld takes an eight character group identi?er.
All IPMs with the same group name can be acted upon simul
taneously by command line actions (ON, OFF, and
REBOOT). The group ?eld can be left blank so that an 1PM is
not part of a group.
The Access ?eld allows changing the access to the associ
ated 1PM for the three default usernames. If a user is using
