8. Respond to the prompts as follows:

for example, 192.1.2.3. You can enter a server name if DNS is enabled.
User name
Enter the user name of your account on the server: for example, JohnDoe.
File name
Fabric OS 5.2.x or higher: Specify the full path name of the firmware
directory, for example, /pub/v5.2.x.
Fabric OS 5.1.x or lower: Specify the full path name of the firmware
directory, appended by release.plist; for example,
/pub/v5.1.x/release.plist.
Note: For v4.x and v5.x switches only, do not attempt to locate the
release.plist file in the top level directory; there is a release.plist file for
each platform, and the correct one is automatically selected.

field even if you are logged in as an anonymous user; in such cases, the
value may be ignored by the FTP service
The firmware is downloaded to one CP blade at a time, beginning with the standby CP blade. During
the process, the active CP blade is failed over. After the firmware is downloaded, a firmware commit
starts on both CP blades. The entire firmware download and commit process takes approximately 35
minutes.
If there is an AP blade present: At the point of the failover an auto-leveling process is activated.
Auto-leveling is triggered when the active CP detects the B-Series MP Router blade that contains a
different version of the firmware, regardless of which version is older. Auto-leveling downloads firmware
to the AP blade, swaps partitions, reboots the blade, and copies the new firmware from the primary
partition to the secondary partition. If you have multiple AP blades, they are updated simultaneously;
however, the downloads can occur at different rates.
Autoleveling takes place in parallel with the firmware download being performed on the CPs, but does
not impact performance. Fibre Channel traffic is not disrupted during autoleveling, but GbE traffic on
AP blades may be affected.
