The Server Administrator Remote Access Service provides a complete
remote system management solution for SNMP and CIM-instrumented systems
equipped with a Dell� Remote Access Card (DRAC) III. The Remote Access
Service provides remote access to an inoperable system, allowing you to get the
system up and running as quickly as possible. The Remote Access Service also
provides alert notification when a system is down and allows you to remotely
restart a system. Additionally, the Remote Access Service logs the probable
cause of system crashes and saves the most recent crash screen.
Throughout this section, in-band refers to communication with the DRAC
III or the managed node system through the managed node system�s NIC
connection or system console. Out-of-band refers to communication with
the DRAC III or the managed node system through the DRAC III�s remote access
ports, which include: Ethernet (embedded NIC), modem (optional), and VT100
serial (optional).
See the Server Administrator Command Line Interface User's Guide for
information about running the Remote Access Service from the command line.
When using the Remote Access Service, you can click Help on the global
navigation bar for more detailed information about the specific window you are
viewing. Remote Access Service help is available for all windows accessible
to the user based on user privilege level and the specific hardware and software
groups that Server Administrator discovers on the managed node system.
NOTE: Remote Access Service is not supported on
the Novell� NetWare� 6.0 operating system.
NOTE: See the Dell
Remote Access Card III User's Guide for complete information
about installing and configuring your DRAC III and for complete
information about using the DRAC III to remotely access an inoperable
system.
The managed node system must have a DRAC III installed in order to use the
Remote Access Service.

The DRAC III contains an integrated 10BASE-T or 100BASE-T Ethernet NIC and supports TCP/IP. The NIC has a default address of 192.168.20.1 and a default gateway of 192.168.20.1.
NOTE: If the DRAC III is configured to the same IP address as another NIC on the same
network, an IP address conflict occurs. The DRAC III stops responding to network commands
until the IP address is changed on the DRAC III. The DRAC III must be reset even if the IP
address conflict is resolved by changing the other NIC.
NOTE: Changing the IP address of the DRAC III causes the DRAC III to reset. If SNMP polls
the DRAC III before the card initializes, a temperature warning is logged because the correct
temperature is not transmitted until the card is initialized.
To configure the network properties of the DRAC III, perform the following steps:
On the Server Administrator home page, click the Main System Chassis
object, and then click Remote Access Controller object.
Click the Configuration tab.
The Configure
Network Properties window appears.
Select Enable NIC (this option is selected by default).
If you want the DHCP system to assign the NIC information, select Use DHCP
(For
NIC IP Address). If you do not, clear (deselect) this check box and enter the DRAC
III's NIC information in the Static IP Address, Static Subnet Mask, and
Static Gateway Address fields.
If you want to enable dial-in networking, select Enable Dial-In (this option is selected
by default).

Use DHCP (For Dial-In IP Address). If you do not, clear (deselect) this check box and enter the
DRAC III modem's Base IP Address.
Specify the type of Dial-In Authentication that dial-in connections
require:
Any allows the connection to use any type of encryption, including no encryption.
Encrypted requires the connection to use some type of encryption.
MSCHAP requires the connection to use the CHAP.
Select Enable SMTP, and type the SMTP (Email)
Server Address.
Click Apply Changes and click OK to save your
changes.
NOTE: You must have
Admin privileges in Server Administrator to use the Remote Access Service.
This subsection describes how to add and configure a dial-in user. After dial-in users are authenticated, they must enter the
Remote Access Service user authentication at the remote access controller login screen to access the DRAC III.
NOTE: The Server
Administrator managed node PPP client uses the 192.168.234.235 network to talk with the
installed DRAC III. It is possible that this network IP address could
already be in use by other systems or applications. If this situation occurs, the PPP connection
fails to operate. If this address is already in use, the user is required to change the
managed node PPP client IP address to a different number. To change the managed node PPP
server IP
address to use another network so that conflicts do not occur, you must use the racadm utility.
See the Dell Remote Access Card III User's Guide for information
about using the racadm utility.
To add and configure a dial-in user, perform the following steps:
On the Server Administrator home page, click the Main System Chassis
object, and then click Remote Access Controller object.
Click the Configuration tab.
Click Dial-In Users.
Click Add.
Type a user name in the User Name field.
Type a new password in the Password field.
Type a callback number in the Callback Number field.
This number is the one the
Remote Access Service calls if Authentication
is set to Preset.
Select an Authentication type from the drop-down menu:
None � When called, the
Remote Access Service does not disconnect and call back; the connection remains active.
Preset � When called, the
Remote Access Service disconnects and calls the number specified in
Callback Number; this setting activates the Callback Number control.
User Specified � When called, the
Remote Access Service asks the user for the callback number. Then the
Remote Access Service disconnects and calls the number the user specified.
Click Apply Changes and then click OK to save your
changes.
NOTE: You must have
Admin privileges in Server Administrator to use the Remote Access Service.
A demand dial-out user is a PPP user who, when calling the
Remote Access Service, causes the
Remote Access Service to disconnect and call the management station back at a preset number. Upon callback, the user
must provide their
Remote Access Service user authentication to access the
Remote Access Service.
NOTE: The Server
Administrator managed node PPP client uses the 192.168.234.235 network to talk with the
installed DRAC III. It is possible that this network IP address could
already be in use by other systems or applications. If this situation occurs, the PPP connection
fails to operate. If this address is already in use, the user is required to change the
managed node PPP client IP address to a different number. To change the managed node PPP
server IP
address to use another network so that conflicts do not occur, you must use the racadm utility.
See the Dell Remote Access Card III User's Guide for information
about using the racadm utility.
To add a demand dial-out user, perform the following steps:
On the Server Administrator home page, click the Main System Chassis
object, and then click Remote Access Controller object.
