is not allowed. For all other usemames this command can
report status for IPMs for Which a usemame has power
control access. For example in “STATUS Device”, the
STATUS command returns information in the form, “n
port(s) on, m port(s) o?‘”. “n” indicates the number of
referenced IPMs that are on. “m” indicates the number of
referenced IPMs that are off. “(n+m)” is the total number of
IPMs that Were referenced by the parameters.
Regarding “SHOW[Page|MODEM] [CONNECT{
[SWITCHIMODEMILINKICONSOLE|NETWORK}]”,
With no parameter or With a page name, this command puts
the poWer manager Commander into the screen oriented
interface mode. With no parameter speci?ed, display starts
at the PoWer Control Screen of the ?rst four poWer modules.
If a page name is speci?ed, display starts at the PoWer
Control Screen With that page name.
With the MODEM parameter, a page is displayed that
shoWs the current modem data rate and the current status of
the modem initialization strings.
With the CONNECT parameter, one of the ?ve serial port
names listed above must be speci?ed. The SHOW CON
NECT command displays the current setting of DSR and
CTS checking for the speci?ed serial port name.
The SHOW command is alWays available to the default
usemames (e.g., admn, genl and gen2). By default neW
usemames are not alloWed to use the SHOW command. The
administrator (e.g., admn usemame) may add and delete
SHOW command privileges to other usernames using the
SET SHOW command.
The “CONNECT{ l l6|SerialPortName|IPMName|
CONSOLEIMODEMILINKINETWORK” command
attempts to make a connection to a serial device attached to
one of the four pass-through ports (CONSOLE, MODEM,
LINK or NETWORK) or to one of 4 side sWitch ports that
are identi?ed by the poWer manager Port Name of the IPM
(IPM Name) on the board. That is, the ?rst side sWitch port
is identi?ed by the Port Name of the ?rst IPM, the second
side sWitch port is identi?ed by the PORT Name of the
second IPM, etc. The CONNECT command can also be used
to connect to l of 16 possible serial ports that are connected
on the LINK port at the end of a chain of poWer managers.
If the CONNECT command is entered With a single param
eter Which is a number from 1 to 16, the connection is
attempted to one of the ports attached to the LINK port at the
end of the chain.
To ease the use of the CONNECT command, an admin
istrator can con?gure any of the possible serial ports that are
available With names. The CONNECT command can then
be used With the assigned name (e.g., the Serial Port Name
parameter) to connect to the port associated With the Serial
Port Name. When the CONNECT command is used With a
Serial Port Name or With a number from 1 to 16 as a
parameter, the IPM access restrictions do not apply. All users
can use the CONNECT command to connect to any serial
port that has a Serial Port Name or is accessed With a number
from 1 to 16.
If the CONNECT command is entered With no param
eters, a list of possible names is displayed on the screen. A
user can then use the CONNECT command With one of the
names displayed to attempt a serial port connection. The
administrator can use the ADD, DEL, and LIST commands
to set up the Serial Port Name con?guration.
For all CONNECT commands, the poWer manager
defaults to requiring that the attached device assert both
Data Set Ready (DSR) and Clear To Send (CTS), in order to
successfully connect. These requirements can be individu
ally enabled and disabled With the “SET CONNECT” com

mand. When a connection is successful, the message “Con
nection complete” Will be displayed, at Which point
communication to the attached device Will be transparent
through the poWer manager.
When ?nished communicating to the serial device, type
“!*login<CR>”. The keyWord “login” is not case sensitive.
This disconnection character sequence returns a user to the
login usemame prompt at Which point a user may login
normally to the poWer manager.
A disconnection Will also automatically occur When CD
or DSR go inactive (as caused by hanging up a modem or
exiting a communications program) or When a Telnet session
is disconnected.
LOGIN brings up the “Usemamezz” prompt to alloW a
user to re-login under a different username. No parameters.
RESYNC ends the session and resynchroniZes the chain
of boards. This command should be issued after adding or
removing a board from the chain if all of the chain is not
accessible. This is an administrative-level command.
VERS displays the ?rmWare version of the ?rst poWer
manager Commander in the chain. No parameters.
QUIT ends the session. No parameters.
Set commands are available When logged in With the
administrative usemame (e.g., admn). To get a display of
available SET commands, enter “SET” at the poWer man
ager prompt, Which Will shoW SET commands are “CON
NECT LOCATION MODEM PANEL PASSWORD SHOW
SCREEN TEMPH TEMPL, LOADL LOADH ENABLET
DISABLET”.
“SET CONNECT {SWITCHICONSOLEIMODEMI
LINKINETWORK}, {DSRCHECKINODSRCHECKI
CTSCHECKI NOCTSCHECK}” turns on or off active sig
nal checking When connecting to a pass-through port When
using the CONNECT command. There are tWo required
parameters With the command. The ?rst is one of ?ve
possible serial port names. The SWITCH serial port name is
for the side-sWitch connection. All four of the possible
side-sWitch connections are controlled by setting the
SWITCH serial port. It is not possible to set individual
side-sWitch connections to different signal values.
DSRCHECK requires that DSR be active from the
attached device to connect. NODSRCHECK ignores that
state of DSR. CTSCHECK requires that CTS be active from
the attached device to connect. NOCTSCHECK ignores that
state of CTS. The defaults are DSRCHECK and
CTSCHECK.
“SET LOCATION {Location}” sets the location descrip
tion ?eld of the PoWer Control Screen for the entire poWer
manager Commander chain. This is an alternative to enter
ing the location description on each PoWer Control Screen,
Which alloWs each PoWer Control Screen to have a unique
name. With this command, spaces can be entered in the
description, Whereas editing the location description from
the PoWer Control Screen does not. The location ?eld of the
?rst PoWer Control Screen is displayed as part of a “Wel
come to . . . ” message When a session is started. Up to 16
characters, including spaces, can be entered. Extra charac
ters Will be truncated from the location ?eld.

“SETMODEM{RATE{NONE|300|l200|2400|4800|9600|192
00|38400}}, SET MODEM {{INIT1|INIT2|INIT2|
ATTENTIONIHANGUP} {DEFAULT|NONE}}”, SET
MODEM RATE sets the initialization data rate for the
modem attached to the poWer manager. The data rate can be
set to any of the listed speeds (300, 1200, 2400, 4800, 9600,
19200, or 38400 Bits Per Second). The NONE parameter is
used to disable all modern initialiZation string support. The
