What Can I Do If the Alarm Sound and Quick Start of DeviceManager Do Not Function Properly on Chrome 55 or Later?

Symptom

The alarm sound is disabled by default. After you use Chrome 55 or later to log in to DeviceManager and enable the alarm sound, sound for new alarms is still not played. Message This plugin is not supported is displayed for Quick Start.

For the browser versions supported by DeviceManager, see the Huawei Storage Interoperability Navigator.

Possible Causes

If the customer's maintenance terminal cannot access Adobe's official website or Chrome 55's built-in Flash Player is not updated, Chrome 55 checks whether the current Flash Player version has security vulnerabilities. If security vulnerabilities exist, Chrome blocks the plug-in.

Procedure

1. Download the Flash Player from Adobe's official website and install it.
2. If the Chrome version is earlier than 57, perform the following operations:
   1. Restart Chrome, type chrome://plugins in the address box, and press Enter. The following page is displayed, as shown in Figure 4-10. If the Flash Player is installed correctly, two Flash Player plug-ins are displayed. The one that ends with pepflashplayer.dll in Location is Chrome's built-in Flash Player, while the other is the newly installed one.

   2. Disable Chrome's built-in Flash Player (clicking Disable) and enable the newly installed one, as shown in Figure 4-11.
