Connecting a USB device
About this task
Perform this task before you install the operating system of the server or transmit data through a
USB device.
The server provides six USB connectors.
• Five external USB connectors on the front and rear panels for connecting USB devices that are
designed to be installed and removed very often:
{ Two USB 2.0 connectors provided by the left chassis ear on the front panel.
{ One USB 3.0 connector provided by the right chassis ear on the front panel.
{ Two USB 3.0 connectors on the rear panel.
• One internal USB 3.0 connector for connecting USB devices that are not designed to be
installed and removed very often.
Guidelines
Before connecting a USB device, make sure the USB device can operate correctly and then copy
data to the USB device.
USB devices are hot swappable. However, to connect a USB device to the internal USB connector or
remove a USB device from the internal USB connector, power off the server first.
As a best practice for compatibility, purchase H3C certified USB devices.
Connecting a USB device to the internal USB connector
1. Power off the server. For more information, see "Powering off the server."
2. Disconnect all the cables from the management module.
3. Remove the management module. For more information, see "Removing the management
module."
4. Connect the USB device. For the location of the internal USB connector, see "Management
module components."
5. Install the management module. For more information, see "Installing the management
module."
6. Reconnect the removed cables to the management module.
7. Power on the server. For more information, see "Powering on the server."
8. Verify that th
e server can identify the USB device.
If the server fails to identify the USB device, download and install the driver of the USB device.
If the server still fails to identify the USB device after the driver is installed, replace the USB
device.
