A smart switch that is a member of a stack retains its stacking 

configuration.

The smart switch provides one USB 2.0 port to upgrade firmware from a disk, back up the 
configuration to a storage device, and allow for the collection of a memory dump for 
debugging purposes.

A device that you attach to the USB port must comply with the following requirements:

The USB device must support USB 2.0.

The USB device must support the FAT32 or VFAT file type. The NTFS file type is not 
supported.

Because of hardware limitations, the write and read speed to and from a USB device is about 
1 Mbps.

In a stack, only the smart switch that functions as the master can 
detect and manage an attached USB device.
