3. At the Software Upgrade menu, type 1 , "TFTP Software Upgrade," and press <Enter>.
4. At the prompt, type the IP address for the source of the software.
5. At the prompt, type Y to confirm the choice.
6. If the file name differs from the default, type it and press <Enter> or press <Enter> to accept the
default.
7. At the prompt, type Y to start the upgrade.
To upgrade a remote unit to the same version of software, follow these steps:

Manage Security
To provide system security, the 3240S includes username and password access, as well as SNMP
with Read and Write communities and a Host table.
The SNMP agent allows access to up to four Host IP addresses listed in the Host Access Table. Set
up the Host information for access to the 3240S on the Host Access Table screen. When a host
attempts to access the 3240S, the IP address is authenticated against the entries on the host table. If a
user attempts SNMP access from a host or network that is not listed in this table, the 3240S rejects
that host and generates an authentication trap. To set up host access, follow these steps:
1. At the SNMP Agent Configuration menu, type 5 , "Host and Community Tables," and press
<Enter>.
2. At the Host and Community Tables menu, type 1, "Access Host Table," and press <Enter>.
3. To add a host, type 1 and press <Enter>, then follow the prompts to enter values for these
parameters:
a. IP Address: for the Host
b. Access Level: Read, Read/Write Read/Trap, or Read/Write/Trap
c. Trap Community: the community name for requests from the host or network
