Remove and Replace a USB Flash Device
To remove and replace a USB flash token memory stick from and into a router, follow these steps:
Note
If the USB flash device is abruptly removed, the constant sync operations of the file system in progress fail
due to the USB device removal. These errors occur with ext2 or ext3 or ext4 file systems and are not seen
with fat32 file system. This is a default behavior on any Linux platform.
The following error messages are displayed when you remove the USB device:
*Jun 24 10:29:45.766: %IOSXE-3-PLATFORM: R0/0: kernel: EXT2-fs (sda1): previous I/O error
to superblock detected
*Jun 24 10:29:45.878: %IOSXE-3-PLATFORM: R0/0: kernel: EXT2-fs (sda1): previous I/O error
to superblock detected
*Jun 24 10:29:46.012: %IOSXE-3-PLATFORM: R0/0: kernel: EXT2-fs (sda1): previous I/O error
to superblock detected
*Jun 24 10:29:46.013: %IOSXE-3-PLATFORM: R0/0: kernel: EXT2-fs (sda1): previous I/O error
to superblock detected
1. Execute the eject usb0: command before removing the USB from the router.
rommon 2 > eject usb0
rommon 2 >
If you do not run this command before removing the USB, the following error message is displayed:
rommon 2 > dir usb0:
2. Pull the memory stick from the USB port.
3. To replace the Cisco USB Flash memory stick, simply insert the module into the USB port labeled USB
MEM, as shown in router Flash Token Memory Stick figure. The Flash memory module can be inserted
only one way, and can be inserted or removed regardless of whether the router is powered up or not.
Connect Ethernet Cables
Note To achieve good performance, it is recommended to use Shielded Twisted Pair (STP) Cat 5E/Cat 6 cables for
all RJ-45 ports on the router.
The router interface modules support RJ-45 and Ethernet SFP ports. For instructions on how to connect cables
to Ethernet SFP ports, see the Connecting Cables to SFP Modules.
The RJ-45 port supports standard straight-through and crossover Category 5E unshielded twisted-pair (UTP)
cables. Cisco does not supply Category 5E UTP cables; these cables are available commercially.
