From your terminal emulator program send the firmware file using Xmodem protocol with CRC or press
CONTROL-D to abort. Upon successful upgrade, the unit will reset and the password> prompt will be
displayed.
Upgrade Modulator
The upgrade Modulator menu option allows upgrading the firmware for the QAM modulator via the local
interface. Remote upgrades cannot be done through a telnet session but can be accomplished via TFTP
over the 10/100 Ethernet interface. Note: Ethernet controller firmware can only be upgraded by TFTP. See
section 6.7 for information on upgrading firmware via TFTP.
To upgrade the modulator, type “4”. The local interface prompt will change to:
Upgrade Modulator [Y/N](N)>_
Upon selecting Yes, the unit will wait for the modulator file. The local interface prompt will change to:

That means that one may be upgraded without changing the other.
