CANOGA PERKINS 9151 Network Interface Device - Manual (Page 24)

Update Software
Each 9151 has two flash memory banks that store software:
• The Active Flash Memory holds the software currently in use
• The Inactive Flash Memory holds the new software from a download or the older version of
software
Software is downloaded to the inactive memory to avoid disrupting service. Resetting the 9151 and
swapping banks does not affect operation and is transparent to user traffic.
You can check the current version of software at the Description Report screen.
If you need to upgrade the software, follow these steps:
1. Download the new software from the Canoga Perkins web site to your FTP or TFTP client;
putting the software in the directory of your choice.
2. Go to the Host Access Table (see page 3-7) and verify that the entry for the host you will use for
the file transfer allows FTP or TFTP access.
3. Transfer the file to the 9145 by either of these methods:
• For a TFTP transfer, go to the DOS prompt on TFTP server, and type "
tftp -i [IP address for
the 9151] PUT [file name for the software] bsw_img " to send the software directly to the 9151.
• For an FTP transfer, go to the command line prompt on your FTP server, and follow these steps:
a. Go to the directory that holds the new software.
b. Type " FTP " and the IP address for the 9151.
c. Log on with your username and password.
d. Type " bin " to enable transfer in binary mode.
e. Put the filename for the new software.
4. When " Transfer complete " appears, you can log on in a regular VT100 session, access the
Utilities menu, and type 4, Swap Banks" to reset the 9151 and start using the new software.
Note: For details on the commands for the transfer process, see the documentation for your FTP or
TFTP software.
Managing Security
To effectively provide system security for a variety of network applications, the 9151 works with
SNMPv3. To use SNMPv3 security, set up the engine ID for the SNMPv3 agent in the device; for
details, see the documentation for the server and software.
As you set up values for various security parameters on your 9151, see the documentation for your
network security system for details on and values for those security parameters. Typically, you must
have supervisor access to set up security for the 9151.
