DSA3017/3018 Firmware Replacement
Replacement of the Firmware chip should only be required if the DSA firmware is upgraded. It is not
expected that this chip might fail in normal use.
When software upgrades are available, customers will be notified by mail or FAX. Upgraded software will
only be made available to customers when requested. It is very important that the replacement procedure
be followed very carefully, otherwise damage to the chip or module may result. It is also very important to
observe ESD safety procedures while replacing this chip.
