name. The command takes no parameters. The output of the
LIST SNAM command is a display of the current serial port
names. Each serial port name is followed by the associated
power manager port for the name. The names are displayed
in groups of twenty ports. After each group of twenty ports
is displayed a user is prompted to press “N” for additional
names or “Q” to end the list. The following is an example of
the screen with twenty serial port names displayed, three are
listed here for illustration,

From the Power Control Screen, a user can control power
and con?gure the power manager by simply moving around
the screen using the arrow keys and pressing an action key.
All con?guration changes made in the Power Control Screen
are saved to non-volatile RAM and are effective immedi
ately. Not all of the power manager hardware supports all of
the functions illustrated in the descriptions. If a capability is
not supported, a user will see an ““N”/A” displayed in the
?eld on the screen.
A Power Control Screen is accessed by a SHOW com
mand from a command prompt,
power manager: SHOW
A SHOW command displays an ANSI power control screen,
e.g., eighty characters wide by twenty-four lines,

Power managers can support up to twenty-siX boards in a
chain of boards. Each board has its own set of four intelli
gent power modules (lPM’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 therefore multiple power control screens (one for each
board). Each power control screen is considered a different
page and each power control screen controls four lPM’s.
The page currently being viewed is displayed in the upper
right comer 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 of the
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 O?). 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 Olf ?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 IPM, 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 Olf ?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 Mini
mum-O?f 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 Olf ?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 Olf ?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 IPM as reported to the
power manager. If the IPM is working correctly, this ?led
will display “Normal”. If the power manager is unable to
communicate with the associated IPM this ?eld will display
“No Rspns”. If the IPM is set to “On” and the power
manager detects the associated IPM is not on, this ?eld will
display “OnS Fail”, e.g., for On Sense Failure. If the IPM is
set to “O?‘” and the power manager detects the associated
IPM is on, this ?eld will display “Off Fail”. Note that power
managers equipped with these “ON SENSE” lPMs can be
con?gured 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
associated IPM. This ?eld is signi?cant if the power man
ager is equipped with the Server Technology “LOAD
SENSE” lPMs that are capable of sensing the load going
through the IPM and relaying this information to the power
manager. If the power manager is not equipped with these
“LOAD SENSE” lPMs this ?eld has no meaning and
