Applicable to: World-Wide

Modem Settings: Use the Modem Settings window to specify advanced modem and dialing settings. To open this window, click on Modem from the Configuration Settings window (see "Configuration Settings" on page 50).

The Port Configuration Group: Use the Modem Settings group to specify and configure the modem that will be used to forward the alert when a System Management Subsystem Dialout Event occurs. The Port Configuration group contains the following items.

Item

Description

Port to configure

Use the spin buttons to select the port that your modem
is configured to use. This spin button will show only values
that are available for use by your system management
subsystem.

The port that you select to use affects the availability of
the modem for use by either the system management
subsystem or the operating system. You can select
Port A, Port B, or Port C.

- If you select Port A on a Netfinity 7000 server, the
modem will be available for use by the operating system
until the system management subsystem uses the modem
for the first time. After the system management subsystem
takes control of the modem, the operating system will not
be able to access or use the modem until the operating
system is restarted.

- If you select Port B on a Netfinity 7000 server, the modem
will be dedicated for use by the operating system only.
The system management subsystem will not be able to
access a modem that is configured to use Port B.

- If you select Port C on a Netfinity 7000 server, the modem
will be dedicated for use by the system management
subsystem only. The operating system will not be able to
access a modem that is configured to use Port C.

Baud rate

Use the spin buttons to specify the baud rate of the modem.

Item

Description

Initialization string

Type the initialization string that will be used for the specified modem. A default string is provided (ATE0). Do not change this string unless your dialout functions are not working
properly. If you need to change the initialization string, see "Initialization String Guidelines" on page 59.

Caller ID string

Type the initialization string that will be used to get Caller ID information from the modem.

Port selected

This check box indicates whether the port number currently displayed in the Port to configure field is the port that is currently designated for use by the system management subsystem. Check this check box if you want to configure the System Management Subsystem to use the currently
displayed port number.

Null modem

Check this check box to use a null modem connection to allow access from a remote Netfinity system.
Note
If the Null modem check box is checked, you cannot send dialout alerts to other systems using a modem or receive dialout alerts from other systems.

Return to factory
settings string

Type the initialization string that returns the modem to its factory settings when the modem is initialized. The default is AT&F0.

Query string

Type the initialization string that is used to find out if the modem is attached. The default is AT.

Escape string

Type the initialization string that returns the modem to command mode when it is currently talking to another modem (connected). The default is +++.

Escape guard time

Type in this field the length of time before and after the escape string is issued to the modem. This value is measured in 10 millisecond intervals. The default value is 1
second.

Dial prefix string

Type the initialization string that is used before the number to be dialed. The default is ATDT.

Dial postfix string

Type the initialization string that is used after the number is dialed to tell the modem to stop dialing. The default is the Carriage Return character or 嘩.

Auto-answer string

Type the initialization string that is used to tell modem to answer the phone when it rings. The default is to answer after two rings or ATS0=2.

Auto-answer stop

Type the initialization string that is used to tell the modem to stop answering the phone automatically when it rings. The default is ATS0=0.

The Dialing Settings Group: Use the Dialing Settings group to specify settings related to the modem, and to configure the modem that is used to forward an alert when a System Management Subsystem Dialout Event occurs. The Dialing Settings group contains the following items.

Item

Description

Dial-in enabled

Check this check box to enable remote users to dial into
and access the system management subsystem. If this
box is unchecked, remote users will be unable to
remotely access the system management subsystem.
Click on Apply after checking or unchecking this check box
to save the new setting.

Dialout retry limit

Use the spin buttons to select the number of additional times
that the Advanced System Management will attempt to
forward an alert.

The Dialout Retry Limit applies only to attempts to forward
the alert information to an alphanumeric pager. If you are
forwarding the alert information to either a Netfinity system
or a numeric pager, only one attempt will be made to
forward this information.

Dialout retry delay

Use the spin buttons to specify the number of seconds that
the Advanced System Management will wait before retrying
a dialout attempt.

Item

Description

Own port on startup

Check this check box to reserve a serial port for exclusive
use by the system management subsystem. If the system
management subsystem is built into your system,
checking this box will reserve one of your system's serial
ports. If the system management subsystem is an adapter,
checking this box will reserve one of the adapter's
integrated communications ports. Click on Apply after
checking or unchecking this check box to save the new
setting.

Notes
1. Check this box if you are configuring your system for
dial-in access. If this check box is not checked, you will be
unable to dial into this system unless the system
management subsystem has reclaimed the port for a
dialout. If you want to configure the system management
subsystem to always be dial-in enabled, regardless of
whether the system is currently powered up, you must
check this check box. When this check box is checked, you
cannot configure the specified port for use by your system.

2. Only the dedicated management port (C) and the shared
serial port (A) are available for use by the Netfinity
Advanced System Management PCI Adapter. The other
serial port (B) is only available for use by the operating
system.

3. Port C is dedicated for use by the Netfinity Advanced
System Management PCI Adapter only. Port A is used by
the operating system, and is available to the Netfinity
Advanced System Management PCI Adapter only when
one of the following conditions exists:

- The server is powered off

- The Netfinity Advanced System Management PCI
Adapter needs a port to perform a Critical Dialout Event (in
this case, the Netfinity Advanced System Management
PCI Adapter seizes control of the port from the operating
system, dials out, and then powers off the server to avoid
damage to your hardware).

Dialout number spacing

If you have configured more than one Dialout Entry to
forward alerts, the system management subsystem will
attempt to contact each of these entries sequentially.
Use the spin buttons to specify the number of seconds for
the system management subsystem to wait between dialout
attempts for separate Dialout Entries.

Dial-in delay (minutes)

The Dial-in delay (minutes) field shows the number of
minutes that must pass after an incorrect User ID or
Password has been used in five successive dial-in
attempts before valid dial-in access will be permitted.
After the fifth successive login failure, dial-in access is
disabled for the number of minutes that you specify, the
system management subsystem adds an entry in
the Event Log noting that dial-in access was suspended
due to five successive login failures, and the system
management subsystem attempts to forward an alert if the
Tamper Enabled Alerts Dialout check box has been
checked (see Figure 4 on page 60).

Initialization String Guidelines: If you need to provide a new initialization string, refer to the user's guide that came with your modem. Your initialization string must contain commands that configure your modem as follows:

- Command echoing OFF
- Online character echoing OFF
- Result codes ENABLED
- Verbal result codes ENABLED
- All codes and Connect messages with BUSY and DT detection
- Protocol identifiers added - LAPM/MNP/NONE
V42bis/MNP5
- Normal CD operations
- DTR ON-OFF hang-up, disable AA and return to command mode
- CTS hardware flow control
- RTS control of receive data to computer
- Queued and nondestructive break, no escape state

Note
The acronyms in these commands have the following meanings:

AA

Auto Answer

CD

Carrier Detect

CTS

Clear to Send

DT

Data Transfer

DTR

Data Terminal Ready

RTS

Ready to Send

Changing Dialout Entry Settings: To apply settings to a selected Dialout Entry:
1. Specify Modem Settings.
2. Specify Dialing Settings.
3. Click on Apply to save these settings and return to the Automatic Dialout Settings window.
