Chapter 8 Maintenance, Backup & Restore

This chapter covers backup, restore, maintenance, and firmware update operations.

8-1 Backup and Restore

Navigation: System → Backup & Restore (or backup under Maintenance, depending on firmware version).

This page backs up and restores device parameters.

Parameter Backup

Back up system parameters and download the file to your computer.

btn:blue:Backup: Exports current device parameters to a file and downloads it.

Parameter Restore

btn:green:Select File: Selects a previously backed-up parameter file to restore.

btn:blue:Restore: Uploads a parameter file and overwrites device settings; back up current settings first.

Backup Contents

Backup files mainly contain configuration settings (alert thresholds, schedules, notification rules, SNMP, network services, engineering parameters, etc.). The following are usually not included and must be reconfigured or verified after restore:

• Historical events and statistics
• User account passwords (verify Users and login credentials after restore)
• Firmware version (restore does not upgrade or downgrade firmware)
• Network IP address (if the backup includes network settings, the IP may change after restore—reconnect using the new address)

8-2 System Maintenance

Navigation: System → Maintenance.

This page sets debug levels, downloads debug logs, and provides system maintenance. Debug levels are for technical troubleshooting; normal operation needs no changes—the factory default is Off for all modules.

Field Descriptions

Debug Information

Each module can be configured independently. When a level is selected, the system logs that level and more severe levels (from most to least severe: Critical → Error → Alert → Info → Debug → Trace; see Debug Level Reference below).

System Control: Log threshold for system core and services (startup, config apply, internal state).

User Manager: Log threshold for login, accounts, and permissions.

Notification Manager: Log threshold for alerts, email, and Pushover delivery.

Hardware Control: Log threshold for sensors, outlet control, and hardware communication.

History: Log threshold for event and history data writes.

Tasks: Log threshold for background and periodic tasks.

Debug Level Reference

Usage Recommendations

1. Troubleshooting workflow: As directed by support, raise only relevant modules (e.g., System Control for network issues, Hardware Control for sensor issues), reproduce the issue, click btn:blue:Download Debug Log, send the file to support, then set levels back to Off.
2. Performance and storage: Debug or Trace increases log frequency and FLASH usage and may slightly affect response time. If FLASH usage on the Information page is high, click btn:red:Free Space.
3. Difference from Event History: History is for operators to query actions and alerts; debug logs on this page are for internal diagnostics and are technical—most users do not need them.

btn:blue:Download Debug Log: Downloads packaged debug logs from all modules (usually a compressed file) for support analysis; download immediately after reproducing the issue.

System Maintenance

btn:red:Free Space: Clears accumulated debug logs to free FLASH space; does not affect alerts, accounts, or general configuration.

btn:red:Reboot Device: Reboots the device; active connections will drop briefly.

8-3 Firmware Update

• SNMP Agent: SNMP monitoring and management
• Mail Server: SMTP and test mail
• Alert Service: External notifications such as Pushover
• Syslog: Syslog server and forwarding

9-1 LDAP

Navigation: Engineering → LDAP.

This page configures and tests LDAP.

Field Descriptions

Enable LDAP: When enabled, login validates against LDAP; when disabled, local accounts only.

Server Address: LDAP server hostname or IP.

Port: LDAP port (commonly 389; 636 with SSL).

Enable SSL: When enabled, uses LDAPS encryption for credential transport.

User ID Attribute: LDAP attribute matching login names (commonly uid or sAMAccountName).

Fall Back to Local Password When LDAP Unavailable: When enabled, uses local credentials if LDAP is unreachable, avoiding login lockout.

Permissions and Account Mapping

LDAP only validates credentials. After authentication, access is determined by the Level (System Administrator, Administrator, Viewer) of the matching account name in Permissions → Users. Create a local account matching the LDAP login name and assign a level first; without it, expected permissions may not apply.

9-1-1 LDAP Test

Procedure

Press btn:orange:Test to open the test window; fill in the account and password and press btn:blue:Test. The LDAP test results will be displayed in the result area.

Field Descriptions

Test Username: Enter the LDAP account to be verified to test whether the binding and search are successful.

Server Address: IP or FQDN of the authentication server.

Port: Authentication service port (commonly 1812 for RADIUS and 49 for TACACS+).

Key: The shared key agreed with the authentication server. When already set, the field shows eight asterisks (********); submitting those eight asterisks on save means the existing key is not changed.

Timeout: Seconds to wait for a server response.

Maximum retries: Number of retries when the connection fails.

Fall back to local password when unable to connect: When the server cannot be reached, whether local accounts may be used to log in.

Permissions and Account Mapping

RADIUS / TACACS+ authenticates accounts against an external server. After authentication, access is determined by the Level of the matching account name in Permissions → Users. Create a local account with the same remote login name and assign a level first. To map permissions from server groups, configure the correspondence between RADIUS/TACACS+ groups and local account levels.

Button Descriptions

btn:gray:Cancel: Discards this change.

btn:blue:Save: Saves RADIUS / TACACS+ settings.
