indicates the number of boards or ports for which the speci
?ed trap is enabled or disabled by the command.
The “SET
DISABLET{STRT|TEMPIMSTAICSTAILOAD} [Port
NamelBoard NamelGrouplALL]” command is used to dis
able an SNMP trap. The SET DISABLET command takes
two parameters. The ?rst is the type of trap to be disabled.
There are four types of traps that are supported by the power
manager. They are:
STRT is a trap generated when the power manager is
started or resynchronized.
TEMP is a trap generated when the power manager tem
perature probe senses a temperature too.
MSTA is a trap generated when an IPM indicates an error
(Module STAus error).
CSTA is a trap generated when a power change occurs
(Control STAus change).
LOAD is a trap generated when the load on an IPM is too.
If the ?rst parameter is not speci?ed the command does not
complete.
The second parameter is the Board Name for board wide
traps (e.g., STRT and TEMP) and is the Port Name for IPM
speci?c traps, e.g., MSTA, CSTA and LOAD. If the Board
Name parameter is not speci?ed on the command line the
power manager prompts for the Board Name with the
“Board:” prompt. If the Port Name parameter is not speci?ed
on the command line the power manager prompts for the Port
Name with the “Port Name:” prompt.
When the command completes the following message is
displayed “Trap Enabled/disabled on X unit(s)/port(s) Com
mand Completed Successfullyl”. The “X” in the message
indicates the number of boards or ports for which the speci
?ed trap is enabled or disabled by the command.
Regarding “LIST TRAP [Board NamelALL]”, the LIST
TRAP command is used to list the current SNMP trap settings
on one or more boards in a chain of boards. The LIST com
mand is also used to list usemames and ports and these func
tions are described in a usemame/password administration
section of this manual.
The LIST TRAP command takes a single parameter that is
the name of the board to be listed. If this parameter is omitted,
the power manager prompts for the board name with the
“Board:” prompt. If a user speci?es and absolute board name
(e.g., a period “.” followed by a letter), information on that
speci?c board will be displayed. If a mnemonic name is
entered, the command will display information on all boards
with that board name with a “Press: “N”) exet, “Q”)uit:”
prompt between board displays. The following is an example
of the display that is returned by the LIST TRAP command,

The display begins with a line that prints the ab solute board
name for the board being displayed. Then a line is displayed
that indicates whether the Start Up trap (STRT) and the Tem
perature trap (TEMP) are active on this board. An “X”

between the brackets means the trap is active. Even if the Start
Up trap is active, start up traps are generated on the ?rst board
in the chain of boards.
The next line shows the current Temperature trap limits for
this board. Following the temperature limits, is a four column
matrix that shows which traps are enabled for which ports on
this board. An “X” between the brackets corresponding to the
trap and the port indicates the trap is active. Only the ab solute
port names are displayed. Following the enabled/disabled
display for the traps, is a display of the current device load
high and low limits for each of the four ports on this board.
Finally, a prompt to continue with the next board or quit is
displayed. When the command is complete a “Port List Com
plete” message is printed.
Usemame/password and Serial Port Name administration
commands are available when logged in with the administra
tive username (e. g., admn). These commands are used to
add/delete users, to allow/disallow access to power manager
IPMs for usernames and to view the current usernames and
their associated IPM access. They are also used to assign
names to the various serial ports that can be accessed via the
CONNECT command.
Regarding “ADD {USERI PORT | SNAME}
[UsemamelSerial Port ID] [Port NamelSerial Port Name]”,
the ADD command is used to add usemames to the system, to
add Serial Port Names, and to add port access to a username.
The ADD command takes one required parameter and up to
two optional parameters.
The ?rst parameter is required and indicates whether a
username is to be added (ADD USER) or whether port access
is to be granted to a user (ADD PORT), or whether a Serial
Port Name is to be added (ADD SNAME).
The ADD USER command is used to add a new username
to the system. The command can be entered with a single
parameter (which is the new username) or with no param
eters. If a parameter is not speci?ed, a user is prompted for a
username with the following prompt: “Usemame:”. A non
blank username that contains no more than 16 characters, and
does not contain the colon “:” character, must be entered at
this prompt or the command is aborted with the following
message: “Sorry, a username a user has entered is NOT
valid!”. A username is not case sensitive.
Once a username is speci?ed, a user is prompted for a
password via the “Password:” message. A user is prompted
for a veri?cation of the newly entered pas sword after entering
the password. The veri?cation password must match the ?rst
password entered or the command is aborted with the follow
ing message: “Sorry, the password a user has entered is NOT
valid!”. The “*” character is echoed in response to the char
acters typed for the password and the password veri?cation
strings. The password value entered at this prompt and suc
cessfully veri?ed is stored as the password for this username
and is used to validate this username during normal power
manager logon processing. The password can not contain
more than 16 characters or the command is aborted with the
following message: “Sorry, the password a user has entered is
NOT valid!”. The password is case sensitive.
Once the information has been entered, a user receives the
following message: “Username successfully added”. Note
that a value in a username is required in this command. Blank
or empty responses to the password prompt and the password
veri?cation prompt are accepted as valid.
By default, a new user does not have access to any
resources on the power manager Board, and cannot use the
SHOW command. To allow a user to access a power module
or a communications connection, the ADD PORT command
