Firmware Upgrade Procedures
Firmware upgrades to an NCC 2020 may be done in two ways:
• Replacing the socketed EEPROMS which hold the node
management and CSU firmware.
• Using either Access Manager 2000 or Node Manager to
download new code to the module.
Replacing
EEPROMs
The TAC 2010 CSU firmware in an NCC 2020 resides in the EEPROM
in socket U11.
The NCC 2020 management firmware resides in the EEPROM in
socket U22.
Verilink offers upgrade kits which include one each of these two
integrated circuits. Contact Verilink Technical Support if you
require a firmware upgrade.
Network
Management
Programs
Both Access Manager 2000 and Node Manager offer download
procedures which may be used to upgrade either the CSU or
network management portions of an NCC 2020.
For details on using Access Manager 2000 to upgrade an NCC 2020
or the other modules it controls, refer to the
