11 - 8 Aironet Wireless Client

When the unit powers up, the boot block checks the integrity of the

application code. If it is valid, the boot block will execute the new ﬁrm-

ware. If it is invalid, the boot block will display an error message on the

Console and the ﬁrmware will need to be reloaded.

The only time you should receive an invalid application code is when

the ﬂash memory device fails or the power is interrupted while the ﬂash

memory is in the process of being programmed.

Downloading or Uploading using the File Transfer Protocol (Ftp)

Use the FTP option to download or upload ﬁrmware. The Aironet Wire-

less Client can be an FTP client or FTP server. To upload or download

ﬁrmware you can initiate a connection from:

n The Aironet Wireless Client console to a remote PC or host and

retrieve a new version of the ﬁrmware.

n The Aironet Wireless Client console to a remote PC or host and send

a copy of the running ﬁrmware.

n One Aironet Wireless Client console to another allowing units to

send or receive ﬁrmware running locally.

n A PC or host system to the Aironet Wireless Client and send a new

ﬁrmware version.

NOTE: Before you download or upload new code versions, make sure you

have set the IP address on all units involved.
