5 Owner Maintenance MIX 56 User Manual
5-10 Telect, Inc. 122188-10 A0
program. Nonredundant systems are updated directly through the Craft
port.
Regardless of which method you use, you must first download the update
from Telect’s website and ensure the files can be accessed by the system
during the update process.
Warning — Do not use HyperTerminal to download upgrades through the
serial port to the MIX 56. Data might be lost while using HyperTerminal to
download the new upgrade. Telect would recommend the use of other ter-
minal programs such as ProComm for doing Serial upgrades. Telect Inc.
uses ProComm (copyrighted by Symantec Corporation) for doing serial
updates.
Warning — Telect recommends that all updates/upgrades be performed in a
maintenance window, and that all configurations be copied prior to per-
forming any updates/upgrades. Performing updates/upgrades on non-re-
dundant M13 single-card systems will cause loss of system configurations,
requiring configuration information to be re-entered after any such update/
upgrade. In addition, performing updates/upgrades on a redundant system
may cause loss of system configurations. If you have any questions, please
contact application engineering before starting any software updates/up-
grades.
TFTP Update
Before beginning, ensure the two update files are on a TFTP server accessi-
ble to the MIX 56 system. You must also know the base name of the update
files and the network address of the TFTP server on which it resides.
NOTE
The TFTP update can only be done on a redundant system. You may want
to Ping the TFTP server to ensure it is up and running. See “To Ping Other
Systems on the Network” on page 4-19.
