The Cisco ASR 9001 Router RP card has an external USB Type A slot accessible on the front panel. The
front panel USB slot accepts widely available USB thumb drives. The only restriction on devices you
can plug into the front panel external USB slot is that they need to be USB 2.0 devices. These devices
can be formatted with FAT16, FAT32 or QNX4 file systems.
The mount point /disk1: is reserved for the front panel USB device.
Note Do not connect a USB hub device to the front panel USB port.
