3.3.7 Update Software
Each 9161 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 9161
and swapping banks will affect the traffic. The ports will temporary go down during initialization..
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 to your computer.
2. Go to the Host Access Table and verify that the entry for the host you will use for the file
transfer allows FTP access.
3. From your computer, follow these steps at the DOS prompt:
a. Go to the directory that holds the new software.
b. Type FTP and the IP address for the 9161.
c. Log on with your username and password.
d. Put the filename for the new software.
5. 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 9161 and start using the new soft-
ware.
3.4 Managing Security
To effectively provide system security for a variety of network applications, the 9161 works with
SNMPv3. To use SNMPv3 security, set up the engine ID for the SNMPv3 agent in the device.
3.4.1 Set General Security Parameters

ues for general parameters, access the Security Configuration screen and follow these steps:
1. From the System menu type 6 , Security Configuration, and press <Enter>.
2. At the Security Configuration menu, type the number for an item and press <Enter>, then
enter data or press <Space> to cycle through the options and press <Enter> to select an
option.
