Removing a USB Flash Device
To remove and then replace a USB flash token memory stick from a Cisco ASR 903 Router, follow these
steps:
Step 1 Pull the memory stick from the USB port.
Step 2 To replace a Cisco USB Flash memory stick, simply insert the module into the USB port labeled MEM
as shown in Figure 3-24 . The Flash memory module can be inserted in only one way, and can be inserted
