The 7210 SAS platform supports the use of the USB interface as an alternate storage location that provides a larger storage capacity than the internal flash. You can use a USB storage device to store TiMOS images, configuration files, accounting records, and log files. The BOF can point to images on the USB and you can use the USB to load TiMOS images and configuration files.
The following guidelines and caveats apply to the use of USB storage devices:
The option to load the boot loader (boot.tim) from a USB storage device is supported on all platforms as described in this document.
USB ports are supported on all 7210 SAS platforms as described in this document, except 7210 SAS-S 1/10GE.
See the 7210 SAS Software Release Notes 22.x.Rx for a list of USB devices and capacities that are supported on the 7210 SAS.
When a USB device is unplugged or removed from the system, a major alarm is raised. The alarm can be cleared using the shutdown command.
The 7210 SAS auto detects the device type when any supported device is connected to the USB interface. Only approved USB mass storage device and optical clip-on devices plugged in to the USB port are recognized as valid devices. The use of unsupported devices generates error logs.
Nokia recommends that the user should run the shutdown command before removing the USB storage device.
