- Home Module Related FAQ:

What USB/micro SD storage formats does the system support?

GCC60xx supports exFAT, ext4, FAT32, F2FS and NTFS for the external storage format. It's recommended to use ext4 format.

Does GCC60xx support multiple account management?

PBX and UC Endpoints module for GCC60xx support multiple accounts. It can be configured under GCC60xx webUI->Home Page-> System Settings->User Management Module.

How can I turn on or turn off email notifications?

Email notifications for GCC60xx can be turned on or turned off via option "Push to Email" under GCC60xx webUI->Homepage->Message Center->Message Settings.

How can I reset the administrator password if I forgot it?

GCC60xx supports password retrieval via email and mobile number. To reset administrator password:

First, you need to log in and navigate to GCC601x webUI->Home->System Settings, go to [Email Settings] or [SMS Settings] to configure SMTP and SMS servers.

Then, you can set your "Email" or "Mobile Number" information under [Setup Wizard] or from Home->System Settings->Security Settings->[Account Settings], which is used to retrieve the password.

If none of them are set, you can restore the device to factory settings and find the initial password on the sticker located on the bottom or back of the device to log in. The initial username is admin. 

What is the default SSID and password broadcast by the GCC6010W?

Once the GCC6010W is connected to a network, it will broadcast a default SSID based on its MAC address and a random password. The SSID consists of the last 6 digits of the MAC address, which you can find on the product box, or the sticker on the bottom of the device. The default password is the same as default Web UI login password.

How can I upgrade firmware for GCC60xx?

Users can log in to GCC60xx Web UI->Home->Maintenance->Upgrade page to perform the upgrade. The following lists various methods for upgrading the firmware.

  • Official online upgrade: This method allows upgrading directly from the Grandstream firmware server. The administrator can click “Detect New Version”to check for any new firmware releases. When a new firmware version is available, the administrator can proceed with upgrading the device.
  • Network upgrade: Typically used for batch upgrading. Users can configure the server address that hosts the firmware file and upgrade devices in batch.
  • Allow DHCP options 43 and 66 to set the server: Typically used for batch upgrading. When enabled, use the server path sent by the DHCP option to request firmware information; when disabled, use the configured server path to request firmware information by default. This configuration does not take effect in the official online upgrade mode.
  • Schedule Upgrade: Assign a specific time schedule for devices to check for and install new firmware.
  • Manual firmware upgrade: Users can directly upload firmware files on the device's Web UI.

How can I restore GCC60xx to factory settings?

Users can reset the device to factory default settings from the web interface or by simply pressing the reset button on the device. 

Method 1: Factory reset the device from the web interface.
- Log in to GCC60xx Web UI->Home->Maintenance->Factory Reset page, click the "Restore to Factory Defaults" button. The reset will be executed after confirmation.
 

Method 2: Hard Reset.
- When GCC6010 is powered on, insert a pin into the reset hole on the back of the device, hold it for 10 seconds, and then release it.
- When GCC6010W is powered on, press and hold the reset button on the bottom of the device for 10 seconds and then release it.
-
When the GCC6011/GCC6020/GCC6021 is powered on, insert a pin into the reset hole on the front of the device, hold it for 10 seconds, and then release it.

For all methods above for different models, the device LED will flash red and then reboot automatically. The factory settings will take effect after device boots up.

What are the functions of the MGMT port/HA port/Console port on GCC6021?

The installation methods supported by different models are as follows:

- MGMT port: used for remote management and monitoring of the device. Use a network cable to directly connect the computer to the MGMT port of the device, and log in to the device through the pre-configured IP address (192.168.1.1) of the MGMT port for Web management.

- HA port: used to achieve high availability between devices.

- Console port: used for initial configuration and subsequent management, using a serial line to interact directly with the command line interface of the device. Serial port login does not involve the network layer and does not require the IP address of the device, but requires the account and password for logging in to the device.
