MAINTENANCE
67.1 Overview
This chapter explains how to configure the screens that let you maintain the firmware and configuration
files.
67.1.1 What You Can Do
• Use the Certificates screen (Section 67.2 on page 424) to see the Certificate screen and import the
Switch's CA-signed certificates.
• Use the Cluster Management screens (Section 67.5 on page 429) to manage the switches within a
cluster and view cluster status.
• Use the Restore Configuration screen (Section 67.8 on page 434) to upload a stored device
configuration file.
• Use the Backup Configuration screen (Section 67.9 on page 434) to save your configurations for later
use.
• Use the Erase Running-Configuration screen (Section 67.10 on page 435) to reset the configuration to
the Zyxel default configuration settings.
• Use the Save Configuration screen (Section 67.11 on page 436) to save the current configuration
settings to a specific configuration file on the Switch.
• Use the Configure Clone screen (Section 67.12 on page 436) to copy the basic and advanced
settings from a source port to a destination port or ports.
• Use the Diagnostic screen (Section 67.13 on page 438) to ping IP addresses, run a traceroute, perform
port tests or show the Switch’s location between devices.
• Use the Firmware Upgrade screen (Section 67.14 on page 440) to upload the latest firmware.
• Use the Reboot System screen (Section 67.15 on page 442) to restart the Switch without physically
turning the power off and load a specific configuration file.
• Use the Tech-Support screen (Section 67.16 on page 443) to create reports for customer support if
there are problems with the Switch.
67.2 Certificates
The Switch can use HTTPS certificates that are verified by a third party to create secure HTTPS
connections between your computer and the Switch. This way, you may securely access the Switch
using the Web Configurator. See Section 57.5.2 on page 361 for more information about HTTPS.
Certificates are based on public-private key pairs. A certificate contains the certificate owner’s identity
and public key. Certificates provide a way to exchange public keys for use in authentication.
