netsnmprw
This command sets the SNMP read-write community string. The community string must be at least
8 and less than 32 characters. Characters must be alphanumeric or the underscore ‘_’. Entering con-
trol-C will quit without changing the community string. There is no query-mode for this command.
Set:
netsnmprw
Chassis response:
System prompts for the SNMP read-write community string.
Factory default setting:

Upgrading Firmware
Periodically, EndRun Technologies will make bug fixes and enhancements to our products available
for download from our website. All such downloads are freely available to our customers, without
charge. After you have downloaded the appropriate FLASH binary image file from the EndRun
Technologies website, you are ready to perform the upgrade to your Distribution Chassis.
For instructions on upgrading firmware using the serial port see
Appendix B
. This section contains
instructions for upgrading firmware via the network port. Upgrading firmware via the TCP/IP net-
work interface is supported using Telnet only. Upgrading via SSH is not supported.
What You Need To Perform the Upgrade
You will need a terminal program which can connect to your FDC3300 via Telnet and supports file
uploading using protocols XMODEM 128 with CRC or XMODEM 1K with CRC. These are very
common file transfer protocols and should be supported by virtually any terminal program. Less
common is a terminal program capable of connecting using Telnet. A recommended program for the
Windows platform is ZOC, available from Emtec: http://www.emtec.com.
Performing the Upgrade
Configure your terminal program to perform XMODEM file transfers with CRC, using either 128
byte blocks or 1K (1024) byte blocks. Then issue this command:
upload<CR><LF>
After issuing this command, you will see the Distribution Chassis respond with this message:
Waiting for download using XMODEM 128 or XMODEM 1K (both with CRC).
Control X will abort download.
CCC...
You will then see the Distribution Chassis send the character ‘C’ every three seconds while it is wait-
ing for you to begin uploading the image file. Should you need to abort the upload process now, send
CTRL-X to the Distribution Chassis. If you abort at this time, your current firmware will remain
intact. If you abort after the file transfer is in progress, you will not retain your original firmware and
will need to re-upload it. You will have to use the RS-232 port to do that.
Otherwise, start the XMODEM upload using the appropriate method for your terminal program.
During the upload, your terminal program will display some sort of status indication. If the upload is
