““N”/A” is displayed. This ?eld will display the current in
Amps when current is ?owing. If the associated IPM 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” lPMs can be con?gured to generate SNMP
traps when load sense values fall outside a user con?gurable
range.
The Minimum-On Time is the minimum amount of time
that an IPM 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 Olf ?elds, however, are
always immediate, ignoring this value. The default is 0.
The Minimum-Off Time is the minimum amount of time
that an IPM 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 Olf ?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 IPM 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 auto
matic 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 lPMs with the same group name can be acted upon
simultaneously by command line actions (ON, OFF, and
REBOOT). The group ?eld can be left blank so that an IPM
is not part of a group.
The Access ?eld allows changing the access to the asso
ciated IPM for the three default usemames. If a user is using
more that the three default usemames on his system, access
must be set via a usemame/password administration com
mands described earlier in this manual. With this ?eld access
can be granted to all three default usemames by setting the
“ALL” value. To limit access to the admn usemame the ?eld
is set to “Admn”. To limit access to the admn and genl
usemames the ?eld is set to “Genl”. To limit access to the
admn and gen2 usemames the ?eld is set to “Gen2”. This
?eld can be modi?ed when logged in with the admn user
name. The admn username always has access to all IPMS.
The default is All.
The Page ?eld is an eight character identi?er to describe
the current screen page, as a more descriptive alternative to
the page numbering in the upper-right-hand corner of the
screen. This entry is used as a parameter to the SHOW
command to display the Power Control Screen of a speci?c
set of four lPMs. If page names are entered, each page
MUST have a unique page name.
The temperature ?eld displays the current temperature in
degrees Celsius as detected by the temperature probe on the
board if the board is equipped with a temperature probe. If
the power manager is not equipped with a temperature
probe, this ?eld has no meaning and ““N”/A” is displayed.

A session can be ended from either the command prompt
or the Power Control Screen,
From the command prompt, type QUIT and press Enter.
From the Power Control Screen, press ‘“‘Q’”’.
A session will automatically be terminated after 5 minutes
of inactivity. With a modem connection, the modem will
automatically be hung-up by the power manager lowering
DTR to the modem, as well as sending the attention and
Hang-up strings to the modem, if they have not been
disabled.
A session will also automatically end when CD or DSR go
inactive into the Modem port, which occurs when the
modem is hung-up or the communication software is exited.
When a session is ended, a user is noti?ed with the
message, “Session ended”. There is then a period of about
?fteen seconds after a session is ended before another
session can be started so the power manager can reinitialize
the modem after a session is ended. If a modem is not used
and the modem initialization strings are turned off, the time
between sessions is about seven seconds.
A non-volatile RAM preferably stores all con?gurable
power manager options, including the passwords, can be
reset to factory defaults. This clears all a user-editable ?elds
on the Power Control Screens and resets all the command
line con?gurable options to defaults, including the pass
words.
Resetting to factory defaults can be done in two ways is
a by an administrative-level command at the power manager
prompt, or by a Reset button press during power up. This
second method is necessary if the passwords are forgotten.
An administrative-level command reset is performed with
the command, “SET CNFG ALL FACTORY”. This will
reset all the power manager products in a chain.
The button press during power up reset must be done on
the ?rst power manager at the beginning of a chain. The reset
is performed by pressing and holding down the Reset button
while turning on power with the On/Olf toggle switch.
Continue to hold down the Reset button for two seconds
after turning on the power, then let go.
This will reset the ?rst power controller board in the
power manager at the beginning of a chain. The rest of the
chain should then be reset by logging in with the adminis
trator username (e.g., admn), and then issuing the adminis
trative reset command shown above.
The network option of the power managers is imple
mented by an OEM version of the MSSl Micro Serial Server
manufactured by Lantronix. This device is enclosed within
the power manager case and provides the Telnet-to-asyn
chronous functionality that allows the power manager to be
accessed over a TCP/IP Ethernet network.
For purposes of this document, the MSSl shall be con
sidered part of the power manager. References will be made
to the power manager as an Ethernet device, when, in
actuality, it is the MSSl inside the power manager that
provides the network functionality. The MSSl will generally
be referred to as the power manager “NIC”.
Before the power manager can be accessed over a net
work, the NIC must ?rst be con?gured with an IP Address,
Subnet Mask, and Default Gateway. These instructions
explain how to con?gure the network parameters through
either a Modern or Console connection.
