System Administration


Performing System Administration Tasks

This section describes the details for performing the following System Administration OfficeConnect Remote 840 Manager tasks:


Controlling Login and Telnet Access

This allows you to set up management access security. The configured username and password combination allows web browser and Telnet access. Connecting to the OfficeConnect Remote 840 with a web browser allows you to configure and monitor your unit using the OfficeConnect Remote 840 Manager. Connecting using Telnet on a workstation allows you to remotely manage the unit using CLI.

A default user name of root and password !root are provided by DHCP Smart Mode and the IP Wizard during the initial installation. For secure access, you should add a private login name and password and delete the default name.

Adding a Login

1 .   From the home page, select Configuration > Global > Administrator > Login. Click Add. The following screen fields appear:

2 .   Enter the following fields:

3 .   After the fields have been entered, click Submit. To clear the fields, click Reset.

Deleting a Login

1 .   From the home page, select Configuration > Global > Administrator > Login. Click Add. The following screen fields appear:

2 .   Select the login name to be deleted.

3 .   Click Delete.


Modifying the Date and Time

This allows you to modify the system date and time.

1 .   From the home page, select Configuration > Global > Administrator > Date and Time. The screen with the following fields appear:

2 .   Enter the date and time information, utilizing the correct formats as shown next to the fields.

3 .   After the fields have been entered, click Submit. To clear the fields, click Reset.


Restoring Factory Defaults

Restoring the OfficeConnect Remote 840 to factory defaults causes all configuration information to be deleted and the unit to be rebooted.

To check the boot mode, go to the Configuration > Global > Administrator > System screen.

If you boot to the unconfigured state, you will need to run IP Wizard or use CLI to reassign an IP address to your OfficeConnect Remote 840. If you boot in DHCP Smart Mode, the IP address will be set to 192.168.200.254.

If you boot in Default Bridge Mode, you may not need an IP address assigned to the unit. However, if you do want one, you must use Command Line Interface. For detailed instructions on using CLI, please see the OfficeConnect Remote 840 CLI User's Guide, printable or viewable from the OCR840 CD.

You can set the switches before you restore the defaults to have the OfficeConnect Remote 840 boot in the mode you wish. See Table 1-2, DIP Switch Modes in Chapter 1 to select the mode you wish.

There are two ways to restore factory defaults:


Using the OfficeConnect Remote 840 Manager to Restore Defaults

1 .   Select Tools > Reboot.

2 .   Select the Delete all configuration and reboot device information option.

3 .   Click Submit.

4 .   Wait one minute. Then, configure an IP address if DHCP Smart Mode is not in use.

5 .   Open up the web browser and start the OfficeConnect Remote 840 Manager by entering the new IP address in the browser location/address box.

Using the Reset Button

1 .   Turn the OfficeConnect Remote 840 off by unplugging the unit.

2 .   At this time, set the DIP switches to their appropriate settings (DHCP Smart Mode, Default Bridge Mode, or Unconfigured Mode). If you select Unconfigured Mode, you can set one of the other modes later using CLI or the OfficeConnect Remote 840 Manager.

3 .   While holding down the Reset button on the back panel, plug the unit back in. You should hold down the reset button for at least five seconds after plugging the unit back in. The unit takes about one minute to come up and the Alert LED will flash until bootup is finished.

4 .   If DHCP Smart Mode is not in use, configure an IP address after the unit comes up.

5 .   Open up the web browser and start the OfficeConnect Remote 840 Manager by entering the new IP address in the browser location/address box.


Updating OfficeConnect Remote 840 Software

See "Upgrading Operational Software for the OfficeConnect Remote 840" in Chapter 10 for information on updating the operational and system software.


Controlling SNMP Access

The Simple Network Management Protocol (SNMP) is used for managing routers and other network devices from a central station or stations. These stations, the SNMP Managers, query the managed units for configuration and monitoring information.

The OfficeConnect Remote 840 can be managed by SNMP Managers in read-only or read-write mode.

Using SNMP to manage the OfficeConnect Remote 840 is more complicated than the preferred method of management, the OfficeConnect Remote 840 Manager.

SNMP access is provided by an SNMP community name and access mode.

To Download the Management Information Base (MIB) files, go to the website, http://www.3com.com/support/ocr840/index.html, and click the drop-down menu under software/MIB downloads.

To set up an SNMP community on the OfficeConnect Remote 840, follow these instructions:

1 .   From the home page, select Configuration > Global > Administrator > SNMP. Click Add and the following screen fields appear:

2 .   Enter the following fields:

3 .   After the fields have been entered, click Submit. To clear the fields, click Reset.

4 .   Repeat steps 1-3 for each management station which is a part of this community.

Be careful to have the Access box checked the same for each new member of the community.

The entire community will be given the access rights of the last member.

5 .   To alter previously set Access Rights, follow step 1 and select the community from the community list and click Modify.

6 .   To delete a management station from a community, go to the home page and, select Configuration > Global > Administrator > SNMP. Select the community and management station from the lists and click Delete.


Controlling TFTP Access

The Trivial File Transfer Protocol (TFTP) provides a simple way to transfer files from one machine to another. The OfficeConnect Remote 840 has a TFTP server that allows you to copy files to or from the unit. All you have to do is set up TFTP access on the OfficeConnect Remote 840 and run a TFTP client program on a workstation. TFTP transfers files over either the LAN or WAN interfaces.

To configure the OfficeConnect Remote 840 to provide TFTP access, follow the instructions below:

1 .   From the home page, select Configuration > Global > Administrator > TFTP. Click Add and the following fields appear:

2 .   Enter the address of the client workstation or select Any Client for unrestricted client access.

3 .   After the fields have been entered, click Submit. To clear the fields, click Reset.


Assigning SNMP Trap Managers

An SNMP trap is an event that causes the OfficeConnect Remote 840 to send an unsolicited message to a SNMP manager.

These events are generally critical events that indicate an operational problem. (Critical events can also be viewed on the OfficeConnect Remote 840 Manager's Monitor > Events > Critical Event Log screen.)

To configure the OfficeConnect Remote 840 to send traps, follow these instructions:

1 .   From the home page, select Configuration > Global > Administrator > TRAP. Click Add and the following screen fields appear:

2 .   Enter the following fields:

3 .   After the fields have been entered, click Submit. To clear the fields, click Reset.

To alter previously set fields, follow step 1 and select an SNMP Trap Manager, then click Modify. To delete a server from your configuration, select an SNMP Trap Manager from the TRAP screen and click Delete.


Assigning Syslog Managers

A Syslog manager is a workstation that accepts and saves informational messages from a network device. The OfficeConnect Remote 840 Manager can be configured to send log messages to a syslog manager as follows:

1 .   From the home page, select Configuration > Global > Administrator > Syslog. Click Add and the following screen fields appear:

2 .   Enter the following fields:

3 .   After you enter the fields, click Submit. To clear the fields, click Reset.
