9. Select the Restricted Mode to set the restrict power control operations:
• Enable: enable restrictions. A user cannot use Serial / Modem access to affect the power
state of the system, such as powering the server on or off.
• Disable: disables restrictions. A user can choose to power the server on or off through a
Serial / Modem connection.
10. Select the Connection Mode.
• Direct Connect: Use direct connect when a system is connected directly to the server
through the Serial port, without using an external modem.
• Modem Mode: use Modem Mode when the Serial port is connected to an external
modem.
11. System Phone Number: enter the telephone number that is used to connect to this server.
12. Click Continue.
To use the System Setup Utility to configure remote modem or serial access:
1. From the SSU Main window, choose Platform Event Manager (PEM).
2. In the PEM window, click Configure EMP and fill in the boxes described in the following steps
(boxes that aren’t listed here are not required for remote access).
3. To require a password for remote access, enter the password in the Enter New Password box
and in the Verify New Password box. Passwords can be from 1 to 16 characters long, using
any ASCII character in the range [32-126]. To clear the passwords, leave both boxes blank.
(You can also clear the password by choose the menu Options > Clear LAN Password.)
4. In the Modem Ring Time box, enter the number of 500ms intervals that the BMC should wait
before taking control of the serial 2 port and answering an incoming call. A value greater than
zero gives the BIOS time to answer before the BMC takes control. A value of zero causes the
BMC to answer immediately. The maximum value, 63, tells the BMC to ignore the call.
Modem Ring Time applies only to Preboot access mode and is ignored for other access modes.
5. In the System Phone Number box, enter the number for the phone line connected to the modem
on the EMP.
6. From the Access Mode list, choose the remote access mode:
• Always Active: the EMP is available at any time.
• Preboot: the EMP is available only when the server is powered down or is running POST
during startup. Once the operating system is loaded, a connection cannot be made.
• Disabled: remote systems are not allowed to initiate connections.
7. From the Restricted Mode list, choose either:
• Enabled: a remote system can initiate a connection, but cannot perform control operations
such as power down, reset, or front panel NMI.
• Disabled: the remote system has full control of the server.
8. From the Connection Mode list, choose either:
• Direct Connect: the Serial B port on the server is connected by a serial cable to the remote
system.
• Modem Connect: the Serial B port on the server is connected to a modem.
